A fuel delivery system for use with a combustion nailer (10) including a cylinder head frame (40,50), the delivery system includes a fuel cell (60) with an outer shell (68) having a closed lower end (92) and an open upper end, a closure (70) crimped over the upper end and defining an opening for accommodating a reciprocating valve stem (64), a fuel cell adapter (80) frictionally engaging the closure and including a flange (90) configured for suspending the fuel cell in the fuel cell chamber (16). The diameter of the flange is greater than that of the fuel cell. A stem receiver block is connectable to the cylinder head frame and includes a stem engagement portion configured for directly and sealingly engaging an end of the valve stem, the stem engagement portion being in fluid communication with an internal receiver passage constructed and arranged for delivering fuel to the combustion chamber. The fuel cell adapter includes a collar projecting normally from the flange and dimensioned for slidingly accommodating reciprocal movement of the stem engagement portion and configured for protecting the valve stem against breakage. |
