ABSTRACT:
A scroll-type fluid machine is provided with a plurality of liquid-confining pockets formed in the sliding surface of the end member of either one of orbiting and stationary scrolls. In operation, a high liquid pressure is generated in the pocket or pockets positioned in the region where a localized high axial urging force is exerted during operation, so that the localized high axial urging force acting on the two scrolls is partially or fully negated.
