Gas-actuated stud setter has pressure casing between stud delivery casing, stud channel axially movable with control rod when delivery casing pushed against spring force to free actuator

摘要

The device has a pistol-shaped housing (2) with a piston (16) movable in a chamber filled with a gas-air mixture, and a stud delivery casing (4) with a spring (9) for setting the initial position. An ignition plug (15) ignites the gas-air mixture and a lockable actuator (27) supplies the plug with electrical energy. A pressure casing (11) between the stud delivery casing and a stud channel is axially movable with a control rod (26) when the delivery casing is pushed against the spring force, whereby the control rod releases the actuator locking element (29).
