Abstract: An air compressor system having a cast separator tank for use with an oil-flooded air compressor. The cast separator tank including an integrally cast air-end inlet opening which is mountable in face-to-face engagement with an air-end discharge opening of the compressor; an integrally cast first channel which extends between the air-end inlet opening and a separation chamber; an integrally cast second channel which communicates with a lower portion of the separation chamber and which extends along an outer portion of the cast separator tank; and an integrally cast lip which extends around an inner wall of the separation chamber. The integrally cast air-end inlet opening which is mounted to the discharge opening of the compressor, serves as a mounting foot, and supports the compressor on its discharge end. The compressor system further having a motor, such that the compressor, the motor and the cast separator tank are attached to from a single unit for ease of handling.

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.

Abstract: An air compressor system having a cast separator tank for use with an oil-flooded air compressor. The cast separator tank including an integrally cast airend inlet opening which is mountable in face-to-face engagement with an airend discharge opening of the compressor; an integrally cast first channel which extends between the airend inlet opening and a separation chamber; an integrally cast second channel which communicates with a lower portion of the separation chamber and which extends along an outer portion of the cast separator tank; and an integrally cast lip which extends around an inner wall of the separation chamber. The compressor system further having a motor, such that the compressor, the motor and the cast separator tank are attached to form a single unit for ease of handling. The compressor system also has a plurality of mounting feet for attachment to an appropriate subbase.

Abstract: A compressor including a prime mover having an output element which supplies a motive force produced by the prime mover; a compression module having an input element; a tensioned belt connecting the prime mover output element and the compression module input element to transmit the motive force from the prime mover to the compression module, and a self-adjusting belt tensioning member for applying a substantially constant tensioning force to the belt to maintain substantially constant the predetermined required belt tension. The compressor also includes an anchor bracket connected to the compression module, and a locator plate connected to the anchor bracket, the locator plate being movable relative to the anchor bracket, the anchor bracket having a stop member for limiting movement of the locator plate.
