ABSTRACT:
An actuator assembly for a stunning gun has a trigger valve in addition to a second shiftable nose piece valve. In use, the trigger valve is manually depressed to open and the user then moves the stunner such that the nose piece shifts as the animal is engaged, whereupon the second valve opens. The stunner will fire only when both valves are simultaneously open, and thus the possibility of inadvertent actuation is significantly reduced. The pneumatic valve assembly requires very little force to operate, in contrast to mechanical trip actuators.
