Abstract
A setting device uses a driving piston for propelling fastening members into a receiving material. High pressure gases within an expansion chamber propel the driving piston through a working cylinder against a fastening element. A vent valve connects the expansion chamber with the atmosphere exterior of the setting device and, normally, the valve is maintained in the open position. A control member, located in part on the outside of the setting device, moves the vent valve into the closed position when a fastening member is to be driven.
