Abstract

A scroll fluid machine has a stationary scroll having a stationary scroll lap and an orbiting scroll having an orbiting scroll lap that orbits relative to the stationary scroll lap. The orbiting scroll lap engages with the stationary scroll lap to form a closed compression chamber. An intermediate ring is positioned to surround the orbiting scroll lap. A plurality of first plate springs connect the intermediate ring and the orbiting scroll, while supporting the intermediate ring to enable the intermediate ring to move in a first direction orthogonal to a rotation axis of the machine. A plurality of second plate springs connect the intermediate ring and the stationary scroll, while supporting the intermediate ring to enable the intermediate ring to move in a second direction orthogonal to the rotation axis of the machine as well as orthogonal to the first direction.
