Abstract
An inlet valve for use in a gas compressor, the inlet valve including a piston movable within a housing chamber toward and away from a housing inlet and a valve disc movable with the piston, the valve disc including an aperture for selectively providing air flow from the housing inlet into the chamber, and a flexible member engageable with the valve disc to close the aperture. The inlet valve also includes a valve seat disposed near the housing inlet, and the piston is movable between a first position where the valve disc contacts the valve seat, and a second position where the valve disc is spaced from the valve seat. A spring biases the valve disc toward the valve seat.
