Patent ID: 7603997

Claim:
An electrical control unit for a pneumatic gun that applies a pneumatic force through a bolt to a projectile to launch it from the pneumatic gun, said pneumatic gun comprising a solenoid valve that directs compressed gas through the solenoid valve to a pneumatic piston to open the bolt during operation of the pneumatic gun, said electrical control unit comprising: a power supply connection that receives power from a power supply arranged in the pneumatic gun; an electrical timing circuit that receives electrical power from the power supply, and outputs signals to the solenoid valve in the pneumatic gun in a timed sequence that is adapted to control a launching sequence of the pneumatic gun; and wherein said electrical timing circuit sends a signal to the solenoid valve, said signal having a sufficient duration to direct a flow of compressed gas through the solenoid valve to the pneumatic piston in a sufficient quantity to open the bolt and load a projectile into the pneumatic gun, wherein said bolt is further configured to supply a quantity of compressed gas through the bolt to the projectile to launch said projectile from the pneumatic gun during a firing operation.
