Abstract
A cooling system for combustion-powered fastener-driving tools comprises the use of cooling fin structures upon the external wall members of the combustion chamber and cylinder. Fluid flow paths are constructed between internal wall portions of a surrounding tool housing and the cooling fin structures mounted upon the external wall members of the combustion chamber and cylinder. In this manner, ambient cooling air is passed over and through the cooling fin structures whereby the combustion chamber and cylinder components of the fastener-driving tool are efficiently cooled such that the temperature level of the fastener-driving tool is maintained at a desirable temperature level despite the substantial amount of heat normally generated during each combustion cycle.
