Abstract
A combustion nailer includes a tool housing, a combustion source disposed at least partially in the housing and including a valve sleeve reciprocating relative to a cylinder head along a tool axis between a rest position and a pre-firing position, a fuel cell chamber in the housing in operational proximity to the combustion source and dimensioned for accommodating a fuel cell, at least one pivot point associated with the fuel cell chamber transverse to the tool axis for facilitating movement of the fuel cell between a non-activated position and an activated position, and at least one actuator pivotable about the pivot point and engaging the valve sleeve at a point closer to the tool axis than to the fuel cell chamber such that movement of the valve sleeve from the rest position to the pre-firing position causes movement of the fuel cell from the non-activated position to the activated position.
