ABSTRACT:
A rotary fluid pump in which thermal seizure and wearing due to thermal expansion are substantially eliminated. The rotary shaft of the compressor is coupled to a front housing through bearing means composed of two ball bearings each having inner and outer races. The widths of one of the inner or outer races of both the bearings are reduced at first sides thereof with the reduced sides confronting each other. First and second retainer rings are provided abutting, respectively, the inner and outer races to push the farther sides of the inner and outer races against a stepped portion formed on the rotary shaft. Soft material can be provided on one or both of the sides of the rotor and/or the circumferential surface of the rotor so that the rotor abuts the front housing and the rear housing through the soft material and/or the circumferential surface of the rotor abuts an inner surface of the center housing.
