HIGH PERFORMANCE VALVE SYSTEM

摘要

This paper covers the design and performance of a radically new valve system now being used in semi-hermetic compressors. The discharge valve, trademarked the "Discus Valve," is made from a high temperature polymeric material. This valve, together with a unique laminated steel valve plate and a ring-type suction valve, provides large flow areas, low clearance volumes, and high efficiency. The development of this valve system required the determination of the long-term physical integrity of the valve material and the design of suitable spring and retention systems. The valve plate development required optimization of performance, durability and machinability. In addition to details of these developments, the paper describes the long-term reliability tests run on components and assemblies to guarantee that reliability as well as performance goals were met.
