ABSTRACT:
A scroll type compressor has a movable scroll which is supported by a drive shaft by way of an eccentric pin in a housing. The movable scroll engages in an orbital movement for defining a compression chamber with a fixed scroll which is disposed opposite to the movable scroll. The compression chamber decreases in size in accordance with the orbital movement of said movable scroll for compressing gas in the compression chamber. A first ring orbits together with the movable scroll between the movable scroll and the housing, for receiving compressive reaction force acting on the movable scroll. A second ring which is secured to the housing receives the compressive reaction force received by and acting on the ring.
