Abstract
For a combustion-powered, fastener-driving tool, a combined ignition and fuel system comprises a battery, two normally opened switches connected to the battery, namely a head switch and a trigger switch, a fuel injector including a solenoid and an associated circuit controlling the fuel injector to enable the fuel injector to inject a combustible fuel for a first time interval, a circuit for producing ignition, and a circuit for monitoring the head and trigger switches, for disabling the injector-controlling circuit if the trigger switch is closed while the head switch is opened or if both switches are opened, for enabling the solenoid if the trigger switch is closed while the head switch is closed, for enabling the ignition-producing circuit after a second time interval succeeding the first time interval, and for disabling the ignition-producing circuit when the injector-controlling is disabled as mentioned. The system further comprises a circuit for monitoring the battery voltage, for comparing the monitored voltage to a reference voltage, and for enabling the injector controlling circuit and the ignition-producing circuit if the monitored voltage is not less than the reference voltage, and for disabling the injector-controlling circuit and the ignition-producing circuit if the monitored voltage is less than the reference voltage.
