摘要： A compressed air nailer comprises a working piston connected to a driving tappet configured to drive a fastener. A trigger and a placing sensor are configured to be actuated to aerate or deaerate a main control line to enable triggering of the driving process. A control valve assembly is configured to define a locked position and an open position by controlling a first pressure in a first control space and a second pressure in a second control space. The first control space is connected to the trigger valve and actuation of the trigger valve is configured to bring the safety valve assembly into the locked position. When the safety valve assembly is in the open position, an actuation of the placing sensor valve is configured to bring the safety valve assembly into the open position when the trigger valve is actuated.

The first control space is connected to the trigger valve and actuation of the trigger valve is configured to bring the safety valve assembly into the locked position. When the safety valve assembly is in the open position, an actuation of the placing sensor valve is configured to bring the safety valve assembly into the open position when the trigger valve is actuated.

摘要： 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.

摘要： A compressed air nailer comprises a control line configured to trigger a driving process when a valve pin is displaced relative to a valve sleeve into an actuated position. The valve sleeve is configured to move between a triggering position and a locked position. A switching surface is coupled to at least one of a trigger and a placing sensor and configured to actuate the valve pin. An outer sleeve is configured to guide the valve sleeve. The switching surface is positioned at a switching surface position relative to the outer sleeve when both the trigger and the placing sensor are actuated. The switching surface is configured to displace the valve pin into the actuated position when the valve sleeve is positioned in the triggering position. The switching surface does not displace the valve pin into the actuated position when the valve sleeve is positioned in the locked position.

摘要： A pneumatic nailer includes a working piston connected to a driving plunger for driving in a fastening means and which is subjected to compressed air when a driving-in process is triggered. The nailer also includes a triggering device which has a manually actuatable trigger and a contact feeler. Actuating the trigger and the contact feeler together activates a first control valve and can trigger a driving-in process. A second control valve is activated when actuating the trigger independently of an actuation of the contact feeler. A chamber is provided, which is either aerated or deaerated via a throttle when the second control valve is activated. A locking piston is provided which is displaced from a resting position into a locked position when the pressure in the chamber passes a predetermined pressure threshold and which in the locked position prevents a driving-in process from being triggered.

摘要： A pneumatic nail gun comprises a working piston connected to a driving ram that is configured to drive in a fastening means and is pressurized by air when a driving process is initiated. A hand-operated trigger and a contact sensor. Simultaneous actuation of the hand-operated trigger and contact sensor activates a first control valve and initiates the driving process if the pressure in a safety control chamber is above a given pressure threshold. A second control valve is configured to be activated upon actuation of the trigger. The safety control chamber is continuously de-aerated via a throttle and is separated from a pressurized casing interior when the second control valve is activated.
