PNEUMATIC NAILER COMPRISING A MANUALLY ACTUATABLE TRIGGER AND A CONTACT FEELER

摘要

Pneumatic nailer comprising
a working piston which is 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, anda triggering device which has a manually actuatable trigger and a contact feeler, wherein actuating the trigger and the contact feeler together activates a first control valve and can trigger a driving-in process, characterized bya second control valve which is activated when actuating the trigger independently of an actuation of the contact feeler,a chamber which is either aerated or deaerated via a throttle when the second control valve is activated, anda locking piston 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.
