ABSTRACT:
A scroll fluid machine has a stationary scroll having a stationary scroll lap fixed to a scroll casing and an orbiting scroll having an orbiting scroll lap that orbits relative to the stationary scroll lap. The stationary and orbiting scrolls are connected via a coupling mechanism other than an Oldham coupling or pin crank type mechanism having sliding parts. The coupling mechanism includes plate springs that connect the stationary scroll to the orbiting scroll. The orbiting scroll lap engages with the stationary scroll lap to form a closed compression chamber.
