PNEUMATIC TOOL WITH INCREASED POWER CAPABILITY

摘要

A pneumatic tool (10) includes a housing (12) defining an air inlet (22) and first (70) and second (76) exhaust passages and an air motor (20) fluidly coupled to the air inlet (22) and disposed in the housing (12). The motor (20) produces exhaust air in operation and is fluidly coupled to the first and second exhaust passages (70, 76). The tool (10) also includes an exhaust valve (84) for selectively opening and closing only the second exhaust passage (76).
