FUEL CELL ACTUATION MECHANISM FOR COMBUSTION-POWERED TOOL

摘要

A combustion nailer (10) includes a tool housing (12), a combustion source (14) disposed at least partially in the housing and including a valve sleeve (24) reciprocating relative to a cylinder head (42) along a tool axis (A) between a rest position and a pre- firing position, a fuel cell chamber (34) in the housing in operational proximity to the combustion source and dimensioned for accommodating a fuel cell (36), at least one pivot point (56) associated with the fuel cell chamber (34) transverse to the tool axis for facilitating movement of the fuel cell (36) between a non-activated position and an activated position, and at least one actuator (50) pivotable about the pivot point (56) and engaging the valve sleeve (24) at a point (54) closer to the tool axis (A) than to the fuel cell chamber (34) 2 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.
