Abstract

A combustion driven fastener hand tool is disclosed having an extruded front body component including two to three parallel bores. A first bore forms a cylinder for the piston which drives the fastener. A second bore forms a primary combustion chamber in which a fuel and air mixture is ignited and directed into the adjacent piston cylinder. A third bore (or alternately an attached component) forms a pathway for the fuel and air mixture to be directed into the primary combustion chamber. The combustion driven fastener hand tool includes numerous other features affording improvements over the prior art.
