Abstract: A swash plate type compressor is disclosed, wherein a shoe, having a first surface slidably disposed on a swash plate and a second surface received in a pocket formed in a piston, is formed from a copper alloy.

Abstract: A variable displacement compressor includes a housing and a rotatable shaft supported within the housing. A pin extends generally outward from the shaft and includes a generally cylindrical distal end. A sleeve is slidably mounted about the shaft and rotates with the shaft. A swash ring is pivotally supported on the sleeve by a pair of bearing pins that extend radially outward from opposite sides of the sleeve and pivotally engage the swash ring. The swash ring is rotatable with the shaft and includes a radially inwardly open spherical pocket. A spherical bearing insert is positioned within the pocket and the cylindrical distal end of the pin slidably engages the spherical bearing insert. The swash ring defines an adjustable angle with respect to the longitudinal axis of the shaft. A biasing member engages the sleeve and biases the sleeve along the shaft.

Abstract: An oil separator-muffler for a compressor includes an inner chamber with an oil accumulation region and a wall positioned in the inner chamber. The wall defines a separator region and has an impingement surface. The arrangement of the wall in the inner chamber defines flow channels of varying cross-sectional areas. A mixture inlet for the separator-muffler provides a passageway for an oil gaseous refrigerant mixture to flow from the exterior of the separator-muffler into the separator region. The oil is separated from the mixture as the mixture impinges against the impingement surface and flows into the oil accumulation region. A channel in fluid communication with the oil accumulation region provides a passageway for the separated oil from the accumulation region to the exterior of the separator-muffler.
