Abstract:
A swashplate type compressor, comprising:a cylinder block defining a cylinder bore and a crank chamber; a housing member attached to the cylinder block and defining a main aperture, an annular groove disposed around the main aperture, and a plurality of oil collection grooves extending outward from the annular groove, each oil collection groove being in fluid communication with the annular groove and having a first wall that is substantially perpendicular to the plane of the housing member and a second wall that is angled with respect to the first wall and the plane of the housing member; a bearing disposed in the main aperture; a shaft rotatably mounted within the main aperture on the bearing such that one end of the shaft is disposed in the crank chamber; a piston reciprocally disposed within the cylinder bore; a swashplate fixedly mounted to the shaft and disposed within the crank chamber; and shoes which slideably intervene between the piston and the swashplate such that rotational movement of the swashplate translates to linear reciprocating movement of the piston within the cylinder bore.
