PNEUMATIC NAILING GUN WITH SAFETY CHAMBER Russian patent published in 2019 - IPC B25C1/04 B25C1/00 

FIELD: tools for repair and construction; pneumatic engineering.

SUBSTANCE: invention relates to a pneumatic nailing gun. Gun comprises working piston connected with driven hammer for clamping fasteners and configured to be loaded by compressed air at start-up of drive, trigger device comprising manual trigger and contact sensor, wherein combined activation of the trigger mechanism and the contact sensor enables to actuate the first control valve and start the clogging process if the pressure in the safety chamber exceeds a predetermined threshold pressure, and a second control valve configured to actuate it when the trigger is actuated regardless of actuation of the contact sensor, at that, independent of second control valve position, there is possibility of continuous bleeding of air from safety chamber through throttle, and when the second control valve is actuated it is possible to separate safety chamber from inner space of pressurized housing.

EFFECT: technical result consists in improvement of safety mechanism of gun.
