  • Control valve means for pressurized air-operated devices for driving fasteners into workpieces
    Patent number: 4915013
    Abstract: Control valve means for a driving tool operated with compressed air for the driving of fasteners into workpieces. Through a specific design of the main and the auxiliary valve and through a connection to the piston return chamber the control of the valves are brought into synchronization with the movement of the working piston. By this, high repetition frequencies can be achieved. Further, in the mode "automatic operation" also single shot operation is possible.
