PNEUMATIC NAIL GUN WITH SAFETY VALVE UNIT Russian patent published in 2022 - IPC B25C1/04 

FIELD: building tools.

SUBSTANCE: invention relates to a pneumatic nail gun. The gun contains a case with a handle and an end tool, while there is a safety valve unit in the case, containing the first control chamber and the second control chamber and made with the possibility of movement between a locking position and an unlocking position by control of pressure in the first control chamber and in the second control chamber. In this case, there is a main control channel in the case, which, in the unlocking position, is connected to the control valve unit, and, in the locking position, is disconnected from the control valve unit. At the same time, the first control chamber is connected to a trigger mechanism valve in such a way that the safety valve unit is in the locking position, when the trigger mechanism valve is actuated, until a contact sensor valve is actuated. Moreover, the second control chamber, in the unlocking position, is connected to the contact sensor valve in such a way that the safety valve unit is in the unlocking position, when the contact sensor valve is actuated, with the actuated trigger mechanism valve.

EFFECT: development of a pneumatic nail gun with an effective, durable, and reliable safety mechanism.
