SCROLL COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To provide an asymmetrical scroll compressor having good operating efficiency. SOLUTION: The scroll compressor has an outer compression chamber bypass port with a check valve, which is formed in an end plate of a fixed scroll and brings a tip portion of an outer compression chamber Y into communication with a discharge chamber when an orbiting scroll turns from an angular position of confining the outer compression chamber Y over a bypass turning angleθoutand a confined volume Vout(0) of the outer compression chamber Y is decreased to a predetermined bypass volume Vout(a), and an inner compression chamber bypass port with a check valve, which is formed in the end plate of the fixed scroll and brings a tip portion of an inner compression chamber X into communication with the discharge chamber when the orbiting scroll turns from an angular position of confining the inner compression chamber X over a bypass turning angleθinand a confined volume Vin(0) of the inner compression chamber X is decreased to a predetermined bypass volume Vin(a). The bypass turning anglesθoutandθinare set so that Vin(a)/Vin(0)>Vout(a)/Vout(0) is satisfied. COPYRIGHT: (C)2007,JPO&INPIT
