Structure Design of a New Kind of Rotary Refrigeration Compressor

This paper introduces the working principle and components structure of a new kind rotary refrigeration compressor which receives the merits of some existing rotary refrigeration compressors and discards some application limitation. The new type refrigeration compressor has the characteristics of fewer parts as well as simple structure, easy manufacturing, smooth operation and wide application capacity. In this paper the author puts emphasis on the discharge structure, capacity regulation mechanism, piston flexibleness and seal body.
