WOBBLE PLATE TYPE VARIABLE DISPLACEMENT COMPRESSOR

Disclosed is a wobble plate type variable displacement compressor that uses a constant velocity universal joint mechanism, which comprises an inner ring and an outer ring, balls that are held between guide grooves of the inner ring and the outer ring to transmit power, and a sleeve, which functions as a wobble central member of the wobble plate, which is rotatable relative to a main shaft and is movable in the axial direction, and which is engaged with the inner ring movably in the axial direction. In the compressor, an inner ring rotation preventing mechanism is constructed as a contoured interlock mechanism formed between the outer circumference of the inner ring and the inner circumference of a housing, and a swash plate minimum inclination angle regulating mechanism, which regulates the minimum inclination angle of the swash plate by abutting the axial ends of the inner ring side and the housing side of the contoured interlock mechanism to each other, is provided to the contoured interlock mechanism. The accuracy of the minimum inclination angle regulation can be improved, and the abrasion resistance of the inner ring rotation preventing mechanism can be improved in the wobble plate type variable displacement compressor using this specified constant velocity universal joint mechanism.
