Abstract
A drilling apparatus for directional drilling. A freely moveable connecting plate is seated in a seating provided for in a drill string motor support. The plate connects a drill string motor and a cylinder drive so that any mechanical stress transmitted by a drill string connected to the motor is substantially damped by the moveable plate. The result is that the drill string remains relatively true running to accurately bore while additionally preventing mechanical stress from damaging the cylinder, drill string motor or support therefor.
