Abstract
An expander driven compressor assembly is disclosed comprising a scroll-type expander having at least one pair of meshed axially extending involute spiral wraps wherein one of the wraps orbits relative to the other wrap and a scroll-type compressor having at least one pair of relatively orbiting meshed axially extending involute spiral wraps. The orbital wrap of the expander is drivingly connected to the orbital wrap of the compressor through a common synchronizer and counterweight assembly. Auxiliary drive power developed by the expander and not required to drive the compressor is used to drive a power take-off shaft. In addition, expansion struts are proved to compensate for thermal expansion or contraction of the relatively orbiting scroll wraps. By this arrangement, a compact and efficient expander driven compressor assembly is achieved.
