Patent ID: 7976294

Claim:
A scroll fluid machine comprising: a first scroll having a first scroll lap; a second scroll having a second scroll lap that is engaged with the first scroll lap and forms a closed compression chamber together with the first scroll lap; an intermediate element that transmits torque between the first scroll and the second scroll; a first plate spring element that connects the intermediate element to the first scroll and supports the intermediate element to enable the intermediate element to move in a first direction orthogonal to a rotation axis of the machine; and a second plate spring element that connects the intermediate element to the second scroll and supports the intermediate element to enable the intermediate element to move in a second direction orthogonal to the rotation axis of the machine as well as orthogonal to the first direction, wherein a revolving axis of the first scroll and a rotation axis of the second scroll are placed with an eccentricity so that the first scroll revolves relatively around the second scroll.
