ABSTRACT:
An improved scroll type compressor is disclosed. A moveable scroll is eccentrically connected to a rotary shaft and opposed to a fixed scroll for forming a compression chamber. The moveable scroll performs an orbital movement about an axis of the rotary shaft without rotating about its own axis. With the orbital movement, the moveable scroll reduces the volume of the compression chamber and compresses coolant gas therein. A fixed wall is disposed adjacent to the moveable scroll on the opposite side from the fixed scroll. The fixed wall receives a reaction force of the compressed gas applied to the moveable scroll. First elements disposed between the fixed wall and the moveable scroll transmit the reaction force from the moveable scroll to the fixed wall. Second elements are disposed independently from the first elements between the fixed wall and the moveable scroll for determining the orbit of the moveable scroll.
