Internal combustion fastener driving tool manual recycler

摘要

The present invention relates to a fastener driving tool operable through an internal combustion driven piston. The stool includes a pump system having an intake system, an exhaust system, a pump sleeve, a pump housing, and a piston housing. The pump sleeve sealably contacts the piston housing and defines the space around the piston housing. The pump housing is arranged and configured to axially in the space and to sealably contact the pump sleeve. A pump compression spring in the space axially biases the pump housing. The intake system is arranged and configured for fluid communication with the combustion chamber. The exhaust system is arranged and configured for fluid communication with the space. The tool can also include a linear cam system and fuel valve; a fuel metering system; and/or a trigger.
