  • Patent number: 4457680
    Abstract: A rotary compressor of the type in which a female rotor and a male rotor turn in opposite directions in the compressor casing, the female rotor having at least one pocket therein that receives at least one lobe on the male rotor, the lobe sweeping a cylindrical side wall of the casing to effect compression of a gas. A sealing rib is provided on the female rotor on the trailing side of the pocket, and a recess is provided on the male rotor at the rear of the lobe for receiving this rib. The female rotor has a peripheral surface extending rearwardly from the rib with respect to the direction of rotation of the female rotor, and terminating in the same or a different pocket, this peripheral surface being spaced a substantial distance radially inwardly of the surrounding cylindrical side wall of the casing, the rib sweeping this side wall with close clearance and hence effecting a portion of the compression of the compressor.

  • Patent number: 4402342
    Abstract: A compressor valve assembly for use with a gas compressor, comprises a valve seat, a valve guard, and between the valve seat and the valve guard a valve seat plate and a resilient valve member disposed side-by-side. These members are apertured with the apertures of the valve member and valve seat plate out of registry with each other, the valve member being adapted to flex toward and away from the seat plate thereby to open and close the apertures through the seat plate. The valve member has a plurality of radially extending arms that interconnect the central portion of the valve member with a peripheral portion of the valve member, and generally radially extending slots through the valve member bordering these arms. The valve seat plate has radially extending imperforate portions that underlie these slots, thereby to close the slots in the closed position of the valve assembly so as to prevent leakage of gas through those portions of the slots that overlie annular grooves in the valve seat.

  • Patent number: 4350475
    Abstract: An air cooled compressor is provided with a centrifugal type fan mounted on one end of a motor shaft. Cooling air is drawn through a shroud for bearing eccentric and connecting rod cooling. A shroud also directs the cooling air drawn and delivered by the fan, over the external surfaces of thinned cylinders and cylinder heads. The cooling air flowing over the thinned cylinder heads also functions to cool the intake air which assists in reducing the temperature experience within the compression chambers of the compressor. A pair of oppositely disposed openings are formed in the wall of each cylinder, which openings register with a wrist-pin that connects a connecting rod to a reciprocating piston when the piston is in the lowermost portion of a stroke within the cylinder. This construction allows the cooling air to flow through the hollow wrist-pin for cooling purposes.
