- paintballs 110 are loaded 601 into the launching area 114 using a gravity feed or a force feed from a detachable hopper (not shown) through a short length feed port 5 as is well known in the art. Once loaded, the paintball 110 is unconventionally motivated from the launching area 114 by the exhaust of combustion gases from the combustion chamber assembly 300 .
- An understanding of the fuel supply, electrical circuitry, operational characteristics, and control system provides an understanding the launching of the paintball 110 .
- the combustion paintball marker 100 uses a fuel cell assembly 1 to supply the marker 100 with the combustible material 301 from a fuel cell cartridge 103 .

- the drawings also show how the fuel cell retainer 7 attaches to the fuel adapter assembly 33 perpendicular to the barrel assembly 29 of the paintball marker 100 .
- a perpendicular attachment was chosen to provide a forward grip for the marker, although it is envisioned that forward, backward, or sideways angles may also be utilized to provide differing grip arrangements.
- FIGS. 7 though 12 one may see that when the fuel cell retainer 7 attaches to the fuel adapter assembly 33 , the fuel cell adapter 2 is connected down onto the fuel cell cartridge 103 .
- the fuel cell adapter 2 fits around the fuel cell port 102 forming a pressure-tight seal. This seal allows for the fuel cell depressor pin 17 to press upon the fuel cell port 102 to release the combustible material 301 stored within the fuel cell cartridge 103 .
- the combustible material 301 can then be transported through the fuel injection assembly 400 , contained within the fuel adapter assembly 33 , into the combustion chamber assembly 300 for ignition by the ignition assembly 200 .
- the fuel injection assembly 400 is preferably constructed from a non-fuel reactive material that may withstand the environmental conditions that the marker will be subjected to during the normal lifetime of the marker.
- the combustible material passes through the fuel cell adapter 2 and around or through the fuel cell depressor pin 17 to a filter 14 .

- a regulator assembly 31 is attached to the fuel adapter assembly front 401 by a regulator screw 27 .
- the regulator assembly 31 maintains 646 the pressure gradient between the Schrader valve housing 23 and the fuel injection channel 407 . This pressure gradient is necessary to maintain an even flow of the combustible material 301 from the fuel cell cartridge 103 even when the amount of combustible material 301 diminishes.
- the combustible material moves perpendicular to the barrel assembly 29 to a fuel conduit 408 running parallel to the barrel assembly 29 where it runs past a fuel injection pin spring 12 , o-ring fuel valves 9 , 19 and a fuel injection pin 8 .
- a solenoid 15 activated by an electric charge 227 emitted from a battery 25 when trigger 36 is pulled, motivates the fuel injection assembly 400 to allow the combustible material 301 to move into a fuel conduit 409 running perpendicular to the barrel assembly 29 , past o-ring fuel valve 20 , up to a fuel conduit 410 running parallel to the barrel assembly 29 to fuel inlet 411 releasing the combustible material 301 from the fuel injection assembly 400 into the combustion chamber assembly 300 .

- the cocking bolt rear end 343 extends outside of the core assembly 30 to allow for a user to cock the paintball marker 101 .
- the cocking bolt 339 forms a sleeve around the interior bolt 338 with the forward end 344 capable of moving through a channel 345 located in the forward end 342 of the cocking bolt 339 and capable of moving through a channel 346 located in the forward end 347 of the exterior bolt 337 .
- the forward end 347 of the exterior bolt 337 when the marker 101 is cocked, rests within the rear block 315 against the combustion chamber wall component 348 located adjacent to the back chamber wall 311 .
- the combustion chamber wall component 348 is attached to an extending bolt 302 which runs parallel to the barrel assembly 29 . As shown in FIG.

- the trigger solenoid 334 is activated to motivate the lower arm 335 of the sear member 333 forward, thereby motivating the engaging arm 336 of the sear member 333 to release the exterior bolt groove 332 .
- the exterior bolt 337 attached to the exterior bolt spring 340 , is then motivated forward through the rear block bolt channel 331 utilizing the saved potential energy of the exterior bolt spring 340 .
- the chamber wall component 348 and the interior bolt 338 are also motivated forward, constricting the interior bolt spring 341 .
- the movement of the chamber wall component 348 motivates the extending bolt 302 forward to obscure the feed port 5 from allowing more paintballs from moving into the barrel assembly 29 .
- This movement 648 of the extending bolt 302 insures only one paintball 110 is fired when the trigger 36 is pulled.
- the movement of the chamber wall component 348 further creates a combustion chamber 303 for the allowing for the ignition of the combustible material 301 .
- the forward block 314 contains a number of channels and conduits necessary for the operation of the invention.

Further, air is allowed 610 into the combustion chamber 303 through a conduit 350 for mixing 630 with the combustible material. A second electric signal is then transmitted from the battery 25 to the ignition coil 6 and spark plug housing 34 to initiate the ignition 640 of the combustible material 301 . Further details regarding the battery 25 and the electric circuitry 210 are discussed below.
- the combustion reaction contained within the combustion chamber 303 creates a contained pressure forcing the chamber wall component 348 to move forward even further.
- This movement of the chamber wall component 348 forces the interior bolt 338 forward until the interior bolt spring 341 reaches a maximum constriction position.
- the forward movement of the interior bolt 338 is thus limited by the constriction of the interior bolt spring 341 .
- the chamber wall component 348 is able to move forward further than the interior bolt 338 , thus providing a channel 352 within the chamber wall component 348 .
- This channel 352 releases a portion of combustion gases to propel the paintball 110 from the launching area 114 .
- the release of pressure within the combustion chamber 300 thus allows the interior bolt spring 341 to relax to an unconstricted position which allows the interior bolt 338 to move backwards within the compound bolt 329 . Excess combustion gases not expelled through the channel 352 are released 647 through the exhaust conduit 350 .

- U.S. Patent Publication 2004/0144012 to Adams discloses a paintball marker having a combustion-gas-powered engine supplying pressure pulses for propelling paintballs or other projectiles.
- The prior art patents fail to teach either a fuel injection pathway for use with the combustion chamber or a cooling assembly for the displacement of heat resulting from the combustion reaction. Thus, it may be seen that these prior art patents are very limited in their teaching and utilization, and an improved paintball marker is needed to overcome these limitations. What is needed then is a paintball marker utilizing the energy produced from a combustion reaction while dissipating the excess heat from the reaction in an effective manner. Additionally, the art lacks a paintball marker which provides a continuously fixed amount of fuel for propulsion of a paintball despite a diminished pressure or supply of fuel.
- The present invention is directed to an improved paintball marker apparatus. In accordance with one exemplary embodiment of the present invention, a paintball marker is provided using fuel injection system to transmit a combustible material to a combustion chamber for a combustion reaction capable of propelling a paintball from the marker. Of particular note is the actual creation of a paintball marker using a combustion engine including a fuel connection system, a fuel handling system, a fuel injection system, a cooling assembly used to dissipate heat from the combustion reaction, and a paintball loading and handling system.
- Advantages of the present invention include: the connection of a combustible fuel tank to a paintball marker, the loading of a combustible fuel into the paintball maker, the use of a combustible material in a paintball marker as the means for propulsion of the paintball, the use of a pressurized fuel injection system providing a continuously fixed amount of fuel into the combustion chamber despite diminishing amounts of fuel as use continues, the use of a cooling assembly to dissipate excess heat from the combustion chamber after a combustion reaction, the integration f the user into the control of the marker, and the loading and handling system for controlling the movement of the paintball through the marker.
- It is an object of the present invention to provide a paintball marker utilizing combustion energy to propel a paintball from the barrel of the marker.
- Further, it is an object of the present invention to provide a paintball marker with a cooling assembly to dissipate heat created from a combustion reaction.
- Further, it is an object of the present invention to provide a paintball marker with a fuel injection assembly providing a continuously fixed amount of fuel to the combustion chamber despite diminished fuel reserves within the fuel container.
- Further, it is an object of the present invention to provide an electronic paintball marker with a circuit set regulating the fuel injection and fuel ignition in the combustion assembly.
- Further, it is an object of the present invention to provide a combustion-powered paintball marker with a forward-positioned paintball feed port for the insertion of paintballs in front of the combustion chamber assembly.

FIGS. 1 through 12 of the drawings, one exemplary embodiment of the present invention is generally shown as acombustion paintball marker 100 used for launching a paintball 110(seeFIGS. 9-12 ). As noted inFIG. 1 , thecombustion paintball marker 100 has amarker body 101 including abarrel 29, a downward extendinggrip frame assembly 32 housing atrigger 36, an internal launching area 114 (seeFIG. 9 ), an ignition assembly 200 (seeFIG. 12 ), a combustion chamber assembly 300, afuel injection assembly 400, a coolingassembly 500, afeed port 5, and afuel cell retainer 7. Several unique advantages are provided by thecombustion paintball marker 100 of the present invention and the method and apparatus that are utilized to launch apaintball 110. - As best understood from
FIGS. 8 through 12 ,paintballs 110 are loaded 601 into thelaunching area 114 using a gravity feed or a force feed from a detachable hopper (not shown) through a shortlength feed port 5 as is well known in the art. Once loaded, thepaintball 110 is unconventionally motivated from the launchingarea 114 by the exhaust of combustion gases from the combustion chamber assembly 300. An understanding of the fuel supply, electrical circuitry, operational characteristics, and control system provides an understanding the launching of thepaintball 110. - The
combustion paintball marker 100 uses afuel cell assembly 1 to supply themarker 100 with thecombustible material 301 from afuel cell cartridge 103. Thefuel cell cartridge 103 is filled with a quantity ofcombustible material 301, preferably a vapored fuel such as mapp gas, propylene, or propane. Thefuel cell cartridge 103 is preferably a pressurized cylinder withfuel cell port 102 housed within a pressurized body having afuel cell side 106,fuel cell top 105, and fuel cell bottom 104. The body and its components are generally composed of a durable material with non-corrosive characteristics that can withstand the pressure of the fuel it contains. During attachment to thecombustible marker 100, thefuel cell cartridge 103 is placed within thefuel cell retainer 7. Thefuel cell retainer 7 acts as additional protection for thefuel cell cartridge 103 during the physically-demanding sport of paintball. Thefuel cell retainer 7 additionally can feature graphic designs or other stylized aspects to match themarker body 101. - The
fuel cell retainer 7 includes threads for attaching thefuel cell retainer 7 to thefuel adapter assembly 33. Thefuel adapter assembly 33 surface is defined by fueladapter assembly front 401, fuel adapter assembly left side 402, fuel adapter assembly right side 403, fuel adapter assembly back 404, fueladapter assembly top 405, and fueladapter assembly bottom 406. - As shown in
FIGS. 1 through 9 , thefuel cell retainer 7 is preferably attached at the fueladapter assembly bottom 406. The drawings also show how thefuel cell retainer 7 attaches to thefuel adapter assembly 33 perpendicular to thebarrel assembly 29 of thepaintball marker 100. A perpendicular attachment was chosen to provide a forward grip for the marker, although it is envisioned that forward, backward, or sideways angles may also be utilized to provide differing grip arrangements. - Reviewing FIGS. 7 though 12, one may see that when the
fuel cell retainer 7 attaches to thefuel adapter assembly 33, thefuel cell adapter 2 is connected down onto thefuel cell cartridge 103. Thefuel cell adapter 2 fits around thefuel cell port 102 forming a pressure-tight seal. This seal allows for the fuel cell depressor pin 17 to press upon thefuel cell port 102 to release thecombustible material 301 stored within thefuel cell cartridge 103. Thecombustible material 301 can then be transported through thefuel injection assembly 400, contained within thefuel adapter assembly 33, into the combustion chamber assembly 300 for ignition by theignition assembly 200. - As shown in
FIGS. 8 and 9 , once thecombustible material 301 is released from thefuel cell cartridge 103, thecombustible material 301 enters thefuel injection assembly 400 located within thefuel adapter assembly 33. Thefuel injection assembly 400 is preferably constructed from a non-fuel reactive material that may withstand the environmental conditions that the marker will be subjected to during the normal lifetime of the marker. - Immediately after exiting the
fuel cell cartridge 103, the combustible material passes through thefuel cell adapter 2 and around or through the fuel cell depressor pin 17 to afilter 14. Thefilter 14 is preferably a 40 to 45 micron mesh screen. After passing through thefilter 14, thecombustible material 301 enters theSchrader valve housing 23. As shown inFIGS. 8 and 9 , the Schrader valve housing runs parallel to thebarrel assembly 29 of thepaintball marker 100. The Schrader valve 13 allows thecombustible material 301 to move from the area of high pressure to the area of lower pressure on the other side of the valve 13 intofuel injection channel 407. Aregulator assembly 31 is attached to the fueladapter assembly front 401 by aregulator screw 27. Theregulator assembly 31 maintains 646 the pressure gradient between theSchrader valve housing 23 and thefuel injection channel 407. This pressure gradient is necessary to maintain an even flow of thecombustible material 301 from thefuel cell cartridge 103 even when the amount ofcombustible material 301 diminishes. After moving through the Schrader valve 13 into thefuel injection channel 407, the combustible material moves perpendicular to thebarrel assembly 29 to afuel conduit 408 running parallel to thebarrel assembly 29 where it runs past a fuelinjection pin spring 12, o-ring fuel valves fuel injection pin 8. - A
solenoid 15, activated by an electric charge 227 emitted from a battery 25 whentrigger 36 is pulled, motivates thefuel injection assembly 400 to allow thecombustible material 301 to move into afuel conduit 409 running perpendicular to thebarrel assembly 29, past o-ring fuel valve 20, up to afuel conduit 410 running parallel to thebarrel assembly 29 tofuel inlet 411 releasing thecombustible material 301 from thefuel injection assembly 400 into the combustion chamber assembly 300. - The
paintball marker body 101 contains a combustion chamber assembly 300 located posterior to thefeed port 5 parallel to thebarrel assembly 29. The combustion chamber assembly includes an extendingbolt 302, acombustion chamber 303, and acore assembly 30. Thecombustion chamber 303 is defined byfront chamber wall 310, backchamber wall 311, and acylindrical chamber wall 312 extending from thefront chamber wall 310 to theback chamber wall 311. In another embodiment of the invention, thecombustion chamber 303 is defined by thefront chamber wall 304, theback chamber wall 305, thebottom chamber wall 306, thetop chamber wall 307, the left chamber wall 308, and the right chamber wall 309. Thefront chamber wall 310 and backchamber wall 311 extend to theexterior marker surface 107 to form forward block 314 andrear block 315. Theforward block 314 andrear block 315 are substantially square in shape framing the combustion chamber exterior 313 on themarker surface 107. Theforward block 314 is defined by forward block left 316, forward block right 317,forward block front 318, forward block back 319, forward block top 320, andforward block bottom 321. Theforward block 314 further contains a variety of conduits and channels necessary for the operation of the invention which will be discussed further below. Theforward block 314 is further constructed of substantially thick material for the containment of thecombustion chamber 303. Theback block 315 is defined by rear block left 322, rear block right 323,rear block top 324,rear block bottom 325,rear block front 326, and rear block back 327. Therear block 315 further contains a variety of conduits and channels necessary for the operation of the invention which will be discussed further below. The rear block 313 is further constructed of substantially thick material for the containment of thecombustion chamber 303. Theforward block 314 and therear block 315 provide flat surfaces for attachment of sections of themarker body 101 to thecombustion chamber 303. The fueladapter assembly top 405 is attached to theforward block top 320 andrear block top 324. Thecore assembly 30 is attached to and integrated with the rear block back 327. Thebarrel assembly 29 posterior to thefeed port 5 is attached toforward block front 318. - The
core assembly 30 is defined by acylindrical exterior 328 and acompound bolt 329. Thecore assembly base 330 is attached to and integrated with thegrip frame assembly 32. As shown inFIGS. 8 and 9 , thecompound bolt 329 constitutes the interior of thecore assembly 30 and enters therear block 315 through the rearblock bolt channel 331. Thecompound bolt 329 is defined by theexterior bolt 337, theinterior bolt 338, the cockingbolt 339, theexterior bolt spring 340, and theinterior bolt spring 341. As shown inFIG. 8 , theexterior bolt 337 forms a sleeve around theexterior bolt spring 340 and theforward end 342 of the cockingbolt 339. The cocking boltrear end 343 extends outside of thecore assembly 30 to allow for a user to cock thepaintball marker 101. The cockingbolt 339 forms a sleeve around theinterior bolt 338 with theforward end 344 capable of moving through a channel 345 located in theforward end 342 of the cockingbolt 339 and capable of moving through achannel 346 located in the forward end 347 of theexterior bolt 337. The forward end 347 of theexterior bolt 337, when themarker 101 is cocked, rests within therear block 315 against the combustionchamber wall component 348 located adjacent to theback chamber wall 311. The combustionchamber wall component 348 is attached to an extendingbolt 302 which runs parallel to thebarrel assembly 29. As shown inFIG. 8 , when themarker 101 is cocked, the extendingbolt 302 runs along the length of thecombustion chamber 303 and thesear member 333 latches thecompound bolt 329 on theexterior bolt groove 332. Additionally, when themarker 101 is cocked, theexterior bolt spring 340 is extended and theinterior bolt 338 extends through the cockingbolt 339, theexterior bolt 337, and therear block 315 into thecombustion chamber 303. When thetrigger 36 is pulled, thetrigger solenoid 334 is activated to motivate thelower arm 335 of thesear member 333 forward, thereby motivating theengaging arm 336 of thesear member 333 to release theexterior bolt groove 332. Theexterior bolt 337, attached to theexterior bolt spring 340, is then motivated forward through the rearblock bolt channel 331 utilizing the saved potential energy of theexterior bolt spring 340. Thechamber wall component 348 and theinterior bolt 338 are also motivated forward, constricting theinterior bolt spring 341. The movement of thechamber wall component 348 motivates the extendingbolt 302 forward to obscure thefeed port 5 from allowing more paintballs from moving into thebarrel assembly 29. Thismovement 648 of the extendingbolt 302 insures only onepaintball 110 is fired when thetrigger 36 is pulled. The movement of thechamber wall component 348 further creates acombustion chamber 303 for the allowing for the ignition of thecombustible material 301. - The
forward block 314, as mentioned above, contains a number of channels and conduits necessary for the operation of the invention. Theforward block 314 contains amain channel 349 allowing for the movement of the extendingbolt 302 and for the release ofcombustion gases 399 for the propulsion of thepaintball 110. Theforward block 314 additionally contains anexhaust conduit 350, thefuel conduit 409 running perpendicular to thebarrel assembly 29, thefuel conduit 410 running parallel to thebarrel assembly 29, and thefuel inlet 411 for the release of thecombustible material 301 into thecombustion chamber 303. Therear block 315, as mentioned above, contains a number of channels and conduits necessary for the operation of the invention. Therear block 315 contains asolenoid channel 351 running from the ignition coil 6 located in thefuel adapter assembly 33. - As discussed above, after a user pulls the
trigger 36 and thechamber wall component 348 has been motivated forward, an electric signal is transmitted from the battery 25 to thesolenoid 15 to release 620 thecombustible material 301 into thecombustion chamber 303. Further, air is allowed 610 into thecombustion chamber 303 through aconduit 350 for mixing 630 with the combustible material. A second electric signal is then transmitted from the battery 25 to the ignition coil 6 andspark plug housing 34 to initiate theignition 640 of thecombustible material 301. Further details regarding the battery 25 and theelectric circuitry 210 are discussed below. The combustion reaction contained within thecombustion chamber 303 creates a contained pressure forcing thechamber wall component 348 to move forward even further. This movement of thechamber wall component 348 forces theinterior bolt 338 forward until theinterior bolt spring 341 reaches a maximum constriction position. The forward movement of theinterior bolt 338 is thus limited by the constriction of theinterior bolt spring 341. Thechamber wall component 348 is able to move forward further than theinterior bolt 338, thus providing a channel 352 within thechamber wall component 348. This channel 352 releases a portion of combustion gases to propel thepaintball 110 from the launchingarea 114. The release of pressure within the combustion chamber 300 thus allows theinterior bolt spring 341 to relax to an unconstricted position which allows theinterior bolt 338 to move backwards within thecompound bolt 329. Excess combustion gases not expelled through the channel 352 are released 647 through theexhaust conduit 350. The pressure from the reaction additionally motivates the combustion chamber assembly 300 to return to a cocked position for further use. - As can be appreciated by those skilled in the art, combustion reactions release a tremendous amount of energy, much of which is in the form of heat. In the current invention, the presence of a large quantity of heat is detrimental to the proper workings of the
paintball marker 101. In particular, the gelatin of thepaintball 110 cannot withstand high temperatures. The present invention compensates for this heat by providing acooling assembly 500. The coolingassembly 500 encases the combustion chamber exterior 313 and extends between theforward block 314 andrear block 315. The coolingassembly 500 radiates 645 excess heat from the combustion chamber exterior 313 to help maintain a cooler temperature for thepaintball marker apparatus 100. The coolingassembly 500 is defined by a plurality offins 501 extending from thecylindrical base 502 around the combustion chamber exterior 313. The coolingassembly 500 is preferably constructed of a durable material conducive to radiating and wicking away the heat from the combustion chamber assembly 300, such as aluminum, diamond, carbon or any other substance. The plurality offins 501 are defined by a plurality of surfaces, namely a front edge 503, aback edge 504, atop edge 505, a bottom edge 506, aleft edge 507, and aright edge 508. The bottom edge 506 is attached to thecylindrical base 502 of the coolingassembly 500. In a preferred embodiment, the front edge 503 andback edge 504 are rounded to prevent injury to paintball users or snagging of clothing or other items by the plurality offins 501. The plurality offins 501 are positioned upon thecylindrical base 502 radiating from a central point in an appropriate ratio to maximize the efficiency of the coolingassembly 500 without increasing production costs for themarker 101. - As mentioned above, a battery 25 and an
electric circuit 210 are necessary for the current invention. The battery 25 is housed at theposterior end 201 of thegrip frame assembly 32 in abattery housing 24. Thebattery housing 24 is defined by a front 211, a back 212, aleft side 213, aright side 214, a top 215, and a bottom 216. Thehousing bottom 216 consists of thebattery housing door 22 which is affixed to the battery housing bybattery door screw 21. Thebattery housing 24 is attached to thegrip frame assembly 32 byhousing screws 26, 226. Anelectric circuit board 210 is housed within thegrip frame assembly 32. Theelectric circuit board 210 transmits electric charge 227 to thesolenoid 15 to release thecombustible material 301 into thecombustion chamber 303 and transmits electric charge 228 shortly after to the ignition coil 6 for the ignition of thecombustible material 301. -
FIG. 13 of the drawings shows a flow chart of aCombustion launching method 600 of the present invention. The method includes the elements of inserting paintball 601 to the firing chamber, and continues with a parallel process of providingair 610, providingcombustible material 620, regulating the fuel and pressurizing thefuel injection system 646 and then mixing the air andcombustible material 630. The method then uses the element of igniting the mixed air andcombustible material 640 which continues by radiating the excess heat from thecombustion 645, motivatingbolt 648, launching paintball 649 and purging the ignition by-products 647. - Reference numerals used throughout the detailed description and the drawings correspond to the following elements:
