ABSTRACT:
A scroll type fluid machine includes a lever 26 moved to draw a conical locus so that revolution is given to an orbiting scroll member 2, to thereby lower a sliding load and a sliding speed of a sliding portion on which a load is acted in a radial direction by the above principle. Further, the orbiting scroll member is supported in a thrust direction by a thrust force transmission member 50 interposed between the orbiting scroll member 2 and a fixed scroll member 1 to thereby lower a sliding speed of the sliding portion on which a load is acted in the thrust direction. With this arrangement, a scroll type fluid machine having high efficiency and durability can be provided.
