Abstract
In a combustion-powered, fastener-driving tool, a cylinder body mounted fixedly within a housing structure has a combustion chamber defining an axis. A valve sleeve functions to open and close the combustion chamber. A piston operative within the combustion chamber and a driving blade moveable with the piston function to drive a fastener into a workpiece. An improved linkage for moving the valve sleeve includes a workpiece-contacting element and a pair of arms attached to such element and disposed alongside the cylinder body and the nosepiece. An improved, one-piece, interlocking member prevents a trigger from being actuated unless the combustion chamber is closed. Thus, a simple, compact, lightweight tool is provided.
