Abstract (en)
[origin: EP0842744A1] The control gun has a trigger (11) which is pressed at one end (11a) to make the pneumatic motor (8) rotate in one direction and at the other end (11b) to make it turn the other way. The trigger is connected to a piston (21) which moves in a cylinder (22) and is connected on one side by a rod (19) to a compressed air inlet valve (15) and on the other to a cam (30). This interacts with a pusher (51) and a selector to open one of the motor's air inlet ducts while closing the other to determine the direction of rotation.
