Compressed air nailer with safety actuator

A compressed air nailer having an operating pressure and comprising:

• a driving tappet connected to a compressed air supply and configured to drive in a fastener;
• a triggering apparatus configured to trigger a driving process;
• a working piston coupled to the driving tappet, wherein compressed air is supplied when the driving process is triggered;
• a safety actuator configured to be moved 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;
• a throttle;
• a safety control chamber configured to be aerated and deaerated by the throttle, wherein a pressure in the safety control chamber exerts an actuating force on the safety actuator;
• and
• a counterforce generator configured to generate a counterforce that acts on the safety actuator and is directed in an opposite direction from the actuating force, wherein the counterforce is linearly dependent on the operating pressure, and wherein the counterforce is configured to move the safety actuator into the locked position.
