摘要:
A portable, internal combustion power operated working device, such as a setting tool for driving fastening elements into a receiving material, has a combustion chamber (9) for burning an air-fuel mixture. A piston (7, 7a), guided within a guide cylinder (8), is driven by the gas pressure generated by the combustion of the air-fuel mixture. The combustion chamber volume can be varied by at least one displaceable combustion chamber wall (11). To prepare the air-fuel mixture, a metering chamber (67) holds a predetermined quantity of gaseous fuel. Fuel from the metering chamber along with air is drawn into the combustion chamber by a negative pressure produced in the combustion chamber when the combustion chamber volume is increased by displacing the at least one combustion chamber wall (11).

摘要:
An explosive powder charge operated setting tool includes a housing (1), a piston guide (13) for a driving piston (9) located in the housing. The driving piston (9) can be propelled from an initial rearward position through a bore (18) in the piston guide (13) into a forward driving position by gases generated from an ignited cartridge charge (12) in a cartridge chamber (10) located rearwardly of the initial rearward position of the driving piston. A channel (18a, 18b) is located in the housing in flow communication with the cartridge chamber and communicating with the guide bore (8) in the piston guide (13). A check valve (5) is positioned in the channel (18a, 18b) and forms a storage space closed to the ambient atmosphere and made up of a section (18a) of the channel (18a, 18b) closer to the forward driving position of the driving piston and of the guide bore (8). The check valve (5) can be closed by the gas in the storage space.
