PNEUMATIC NAILING GUN WITH SINGLE AND CONTACT START-UP Russian patent published in 2019 - IPC B25C1/00 B25C1/04 

FIELD: instrument engineering.

SUBSTANCE: invention relates to a pneumatic nailing gun. Gun comprises a release device with a manual trigger, a contact sensor and a force transmitting device configured to actuate the control valve which triggers the clogging process and a switching device configured to translate the force transmitting device into a contact start position, in which it is possible to actuate the control valve by means of the said device transmitting force, with the actuator triggered by the contact sensor activation. At that, the switching device contains a control piston configured to transfer the device transmitting force to the contact start position or holding it in the contact start position. Control piston is installed in control cylinder containing control volume, wherein control piston is configured to move to first position in case pressure in control volume becomes greater or less than a predetermined pressure, and in gun is configured to supercharge air in control volume or bleed air from control volume by means of control valve when starting process of clogging.

EFFECT: technical result consists in ensuring optimum safety of operation.
