Patent ID: 8152497

Claim:
A compressor, comprising: a hermetic housing having a refrigerant inlet and a refrigerant outlet; a motor having a stator and a rotor positioned within said housing; a crankshaft including an eccentric, said crankshaft rotatably engaged with said rotor; first and second bearings positioned within said housing, said crankshaft rotatably supported by at least one of said bearings; and a cylinder block moveable relative to said bearings, said cylinder block defining with said eccentric at least one compression chamber configured to receive a refrigerant therein, said eccentric positioned in and engaging said cylinder block whereby rotation of said crankshaft and said eccentric causes reciprocating translation of said cylinder block with respect to said bearings and relative movement between at least one inner wall of said compression chamber and said eccentric to compress the refrigerant in said compression chamber from a suction pressure to a discharge pressure; said hermetic housing comprising a first portion and a second portion connected to said first portion, said first and second bearings being disposed between said first and second portions of said hermetic housing and pressed together by said first and second portions of said hermetic housing; wherein said cylinder block is spaced radially inwardly from said hermetic housing and said bearings radially enclose said cylinder block and contact said cylinder block on opposite axial ends thereof to form said at least one compression chamber.
