Abstract:
PROBLEM TO BE SOLVED: To provide a compressor capable of appropriately assuring a pressing force for pushing a revolving scroll against a fixed scroll when a pressure within a back pressure is lack.SOLUTION: A spring member 60 at a compressor is configured by a bimetal washer, the lower a temperature of refrigerant in a back pressure chamber 403a, the larger a pressing force Fp produced by the spring member 60 against a revolving scroll 402. Accordingly, the lower a refrigerant pressure in the back pressure chamber 403a, the larger the pressing force Fp produced by the spring member 60 in response to the refrigerant temperature in the back pressure chamber 403a. In view of this fact, when the refrigerant pressure in the back pressure chamber 403a acted as the back pressure in a motor axial direction DRm for pressing the revolving scroll 402 against a fixed scroll 401 is lack, it is possible to assure properly the pressing force Fp against the revolving scroll 402.SELECTED DRAWING: Figure 3
