ABSTRACT:
The present invention relates to a scroll fluid machine in use for compressors, expanders and the like, comprising spiral fine regulation elements having the same curvature as each spiral side plate of a fixed scroll and an orbiting scroll and grooves provided in an end face of each spiral side plate of both scrolls and provided with a stepped portion formed halfway thereof for being forced thereinto said spiral fine regulation elements, and axial gap between the end face of each spiral side plate of the fixed scroll and the orbiting scroll and the opposite bottom face of each bed plate being finely regulated by setting depths of putting the fine regulation elements in the grooves, whereby preventing a fluid from leaking in the operation thereof.
