ABSTRACT:
A thrust bearing assembly of a wobble plate type refrigerant compressor for supporting a non-rotatable inclined wobble plate on a rotatable drive element which rotates with a drive shaft, and having a inclined drive face able to convert a rotating motion of the drive element into a wobbling motion of the wobble plate to thereby cause a reciprocation of compression pistons in cylinder bores, the thrust bearing assembly having a plurality of roller elements, an annular retainer elements holding the roller elements therein and rotating in a space between the drive face of the drive element and an inclined face of the wobble plate confronting the drive face, a pair of race elements attached to the drive and inclined faces of the drive element and the wobble plate to provide raceways for rolling of the roller elements, and a circumferentially extended guide way element supplying the annular retainer elements with a constant slide guide during the operation of the compressor irrespective of a change in the operating speed and compression ratio of the compressor.
