Abstract
A scroll compressor having a suction chamber into which fluid is received substantially at suction pressure and a discharge chamber from which the fluid is discharged substantially at discharge pressure, including mutually engaged fixed and orbiting scroll members, in fluid communication with the suction and discharge chambers, an intermediate pressure chamber defined in part by one of fixed and orbiting scroll members, an oil reservoir, an electric motor, and a shaft operably coupling the motor and the orbiting scroll member. The shaft is provided with a longitudinal passageway extending longitudinally therethrough, the longitudinal passageway in fluid communication with the oil reservoir and provided with oil therefrom. The shaft is provided with a first passage in fluid communication with the longitudinal passageway and which extends substantially laterally outward from the longitudinal passageway to a radially outer surface of the shaft. A roller is disposed about the shaft radially outer surface, the orbiting scroll member linked to the shaft through the roller. The roller is provided with inner and outer circumferential surfaces and a second passage extending therebetween, th…
