Abstract: A combustion chamber system, for use in connection with internal combustion powered fastener-driving tools, comprises a dual-level combustion chamber comprising first and second pre-combustion and main combustion chambers, and a dual-level rotary valve mechanism which is operatively connected to the dual-level combustion chamber so as to control the intake of the air/fuel mixture as well as the scavenging or purging of the exhaust gases or combustion products. The first and second pre-combustion and main combustion chambers are also separated by a plate having a plurality of apertures defined therein whereby multiple jets or flame fronts are defined throughout the combustion chamber system.

Abstract: A new and improved combustion-powered fastener-driving tool utilizes a new and improved single component intake/exhaust valve member (112) which integrally defines both the intake and exhaust valves thereon. The intake/exhaust valve member (112) is adapted to be axially movable within the combustion chamber (102), and operatively cooperates with wall, structure of the combustion chamber (102). When the intake/exhaust valve member(112) is disposed, for example, at a first upper position, both the intake and exhaust ports (126, 130) defined within the wall structure of the combustion chamber (102) are closed so as to permit the ignition and combustion phases of the tool-firing cycle to proceed, whereas, conversely, when the intake /exhaust valve member (112) is disposed, for example, at a second lower position, both the intake and exhaust ports (126, 130) defined within the wall structure of the combustion chamber (102) are open so as to permit incoming air to scavenge combustion exhaust products and to subsequently mix with injected fuel in preparation for the commencement of another tool-firing cycle.
