Abstract
A compressed air nailer comprises a driving tappet connected to a compressed air supply and configured to drive in a fastener. A triggering apparatus is configured to trigger a driving process and a working piston is coupled to a driving tappet. A safety actuator is configured to be displaced between a locked position and an open position, wherein when in the locked position, the safety actuator is configured to inhibit the triggering of the driving process when an actuation of the triggering apparatus occurs. The compressed air nailer further comprises a throttle and a safety control chamber configured to be aerated and deaerated by the throttle. A counterforce generator is configured to generate a counterforce that acts on the safety actuator and is directed in an opposite direction from the actuating force. The counterforce is linearly dependent on an operating pressure of the compressed air nailer.
