A pneumatically timed control unit controls a gas operated projectile launching device. At rest, the control unit feeds pneumatic gas from a compressed gas supply to the launching device's loading, launching components and/or mechanisms, and/or gas storage chamber(s). Once the valve is partially activated, the control unit uses pneumatic pressure from the gas storage device to urge the valve to a fully activated position to start the launching and/or loading sequences of the launching device and to pneumatically hold the valve(s) within the control unit in the activated position. The control unit waits for pneumatic feedback and/or absence of feedback/exhausting pneumatic pressure from either the launching device's loading and/or launching components and/or mechanism, or from a gas storage chamber and/or a venting relief-type valve to release the pneumatic hold on the valve. This allows the valve to be shifted to the "at rest" position, ready for the next activation sequence. |
