Abstract: A scroll compressor has a biasing chamber which contains a pressurized fluid. The pressurized fluid within the chamber biases the two scroll members together. A valve assembly is in communication with this biasing chamber and releases the pressurized fluid on demand to remove the load, biasing the two scroll members together. When the biasing load is removed, the two scroll members separate, creating a leakage path between discharge and suction to reduce the capacity of the scroll compressor.

Abstract: A discharge valve assembly (12) is provided for preventing reverse rotation of a scroll compressor. The discharge valve assembly includes a cup-shaped valve member (104) slidably engaged with a central post of a retainer member (106). The cup-shaped valve member (104) includes notches in communication between the central post of the retainer (106) and the sidewalls of the cup-shaped valve member.

Abstract: A compressor assembly (10) includes a planetary gear train (120) located between an input shaft (136) from the power unit and a drive shaft (80) of the compressor. The planetary gear train (120) is switchable between a high speed and a low speed condition. In the high speed condition, power is provided to the planetary gears (132), the ring gear (134) is locked and output to the drive shaft (80) is through the sun gear (130). In the low speed condition, a one-way clutch (122) between the input shaft (136) and the output shaft (80) provides a one-to-one driving ratio.
