ABSTRACT:
A backpressure mechanism for a scroll type compressor to effectively prevent leakage of coolant; a recessed seat being provided at the top of a coolant passage at the center of a fixed scroll; a ring groove being disposed on the outer circumference of the recessed seat; a high-pressure sealing assembly comprised of a high-pressure ring, a sealing device and a high pressure ring seat and a medium-pressure sealing assembly comprised of a medium-pressure ring, a sealing device and a medium-pressure ring seat being respectively provided to the recessed seat and the ring groove; pressure from the compressed coolant causing an axially compromising vacuum unloading function to float the both sealing assemblies.
