Abstract
A uniform cross-section and ribbed thermoplastic compressor valve which can be used as a discharge valve for a compressor and has internal rib structure and uniform wall thickness. The valve member can be made of high-performance polymeric resin such as polyimide. The valve member comprises a base member, an annular wall member, a central member protruding from the base member, and a plurality of internal wall members. The internal wall members provide the internal rib structure which strengthens the valve member and allows for light-weight construction. Preferably, there are six internal wall members and the central member has a cavity.
