COMBUSTION DRIVEN FASTENER HAND TOOL

摘要

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.

主权项

1. A combustion driven fastener apparatus, comprising:
a front body section including a first bore and a second bore comprising a combustion chamber, the first bore parallel to the second bore, where a passage couples the combustion chamber to the first bore at an end of the first bore; a piston disposed in the first bore to drive a fastener; and a primary housing comprising a left half and a right half enclosing the front body section; wherein the combustion driven fastener apparatus is capable of having a fuel and air mixture driven under pressure into the combustion chamber and ignited to generate pressure through the passage and force the piston in the first bore to drive the fastener.
