ABSTRACT:
A combustion-powered fastener-driving tool includes a combustion-powered power source including a cylinder defining a path for a reciprocating piston and an attached driver blade, the piston reciprocating between a pre-firing position achieved prior to combustion and a bottom out position. Upon combustion in the power source, the cylinder includes at least one exhaust valve configured for releasing combustion gases from the cylinder. The at least one exhaust valve is dimensioned so that sufficient gas is released to reduce post-combustion pressure in the cylinder to approximately one atmosphere in the time available for the piston to travel past the at least one exhaust valve and return to the at least one exhaust valve.
