Abstract
A handheld pneumatic power tool apparatus is provided for use with a supply of pressurized air. The apparatus includes a handpiece and a pressure regulator assembly for regulating the pressure of air supplied to the handpiece. The handpiece includes a cylinder having first and second ends, an anvil positioned at the first end of the cylinder, and a piston received in the cylinder for bi-directional oscillating movement between the ends. The pressure regulator assembly includes a valve for controlling air flow to the handpiece, a pressure sensing element for sensing the pressure of the air supplied to the handpiece and for automatically controlling the valve in response to the sensed pressure, a compression spring for biasing the pressure sensing element against the pressure of the air supplied to the handpiece, and a foot pedal operatively connected to the compression spring for adjusting the force exerted by the spring on the pressure sensing element in order to adjust the regulated pressure of the supplied air.
