Developing a Compact Automotive Scroll Compressor

摘要

A compact automotive scroll compressor is developed to substitute an original compressor with equivalent suction volume. Comparing with the original compressor, the outer diameter of the compact compressor is reduced 10%, and the length is reduced 8%, and the weight is reduced 28%. The compact compressor is improved twice to increase its durability. The first improvement is to flat the load profile by moving the scroll center to the orbiting bearing center. The second improvement is to change the balls coupling to pins coupling. Eventually the durability of the compact compressor meets the technical standard requirement.
