ABSTRACT:
In a scroll fluid machine, a stationary scroll fixed to a housing engages with an orbiting scroll to form a sealed chamber between the orbiting and stationary scrolls. Fluid in the sealed chamber is compressed or decompressed with revolution of the orbiting scroll with respect to the stationary scroll. A plurality of self-rotation preventing devices are provided on the orbiting scroll to prevent the orbiting scroll from rotating on its own axis. The self-rotation preventing device comprises an eccentric tube connected to a main shaft fitting in the housing, and an eccentric shaft fitted in a bearing plate. The eccentric tube is eccentrically revolved with respect to the main shaft thereby allowing engagement of the orbiting scroll with the stationary scroll to be adjusted.
