Fluid apparatus of the scroll-type are disclosed wherein radially compliant means effect relative orbital motion between first and second wrap elements such that actual moving line contact occurs between their flank surfaces, and wherein linkage means interconnect one of the wrap elements and crankshaft means such that a component of the force acting therebetween is imposed upon the wrap element in a radially outward direction in order to provide a sealing or contact force between the wrap elements. Counterweight means impose a force upon the wrap element in a radially inward direction which is substantially equal to the centrifugal force experienced thereby, whereby the contact force is made independent of the operating speed of the apparatus and self-compen-sating with respect to pressure conditions therein.
