Granted: 1995-02-11
Abstract: An explosive powder charge operated setting tool contains a channel (7) located between an inner piston guide (2) for a piston (1) and an outer housing part (6). At the rear end of the tool, the channel (7) continues in a carrier (3) and can be in communication with a cartridge receptacle (4) in the carrier (3). In its front region, the channel (7) is connected via a first opening (2c) in the piston guide (2) with a guide bore (2a) for the piston (1). Towards the rear end of the channel (7) there is a valve arrangement for forming a propellant gas storage space connected through the first opening (2c) to the guide bore (2a). Propellant gases within the storage space are compressed by the piston (1) driven in the setting direction and, after completion of the driving or setting procedure, serve to return the piston (1) back into its rear starting position by expansion of the storage space gases. After the driving operation, a second opening (3a) communicating with the ambient atmosphere vents the space rearwardly of the piston (1) so that the piston (1) can move without interference back into the rear starting position and, in addition, any residual gases can escape through the second opening into the ambient atmosphere.
