ABSTRACT:
A thrust ring plate of a scroll type compressing apparatus supports the movable scroll member of the apparatus and has flat and parallel circumferential opposite surfaces extending over an Oldham ring in the bearing frame to bear a thrust pressure occurred by the compressing action of the movable scroll member and the stationary scroll member thereby preventing the movable scroll member from the fluctuating movement in a thrust direction perpendicular to the end plate of the movable scroll member and ensuring a smooth orbital movement of the movable scroll member.
