ABSTRACT:
A variable capacity wobble plate type compressor provided with a reciprocatory piston mechanism for compressing a refrigerant gas and discharging the compressed refrigerant gas, a drive shaft driven by an external drive source to allow an assembly of angularly variable drive and wobble plates to reciprocate the reciprocatory piston mechanism, a coil spring mounted on the drive shaft for applying a biasing force to the assembly of drive and wobble plates toward a predetermined angularly inclined position, and annular spring support members for supporting the opposite ends of the coil spring so that the coil spring is not in contact with the outer surface of the drive shaft, to thereby prevent an abrasion of the coil spring and the drive shaft when the coil spring is contracted and expanded during the operation of the compressor.
