Abstract
Improved seal components for compressors, such as scroll compressors, are provided. Such seal components have a molded composite on a seal plate that is preformed, which serves as an improved face seal for floating seal assemblies. The preformed seal plate may be formed of a sintered powder metal or cast gray iron. The molded composite comprises a thermoplastic polymer and at least one reinforcing or lubricating particle. Methods of forming such seal components for a scroll compressor by injection molding are also provided.
Claims9
A scroll compressor comprising:
- a first non-orbiting scroll member having a baseplate defining a first side and a second side opposite to the first side, wherein the first side comprises an involute portion extending from the baseplate and the second side comprises a cavity having a floating seal assembly disposed therein, the floating seal assembly comprising a seal plate and a molded structural portion overmolded onto a region of the seal plate, wherein the seal plate comprises a metal, the molded structural portion comprises a thermoplastic polymer and at least one reinforcing or lubricating particle, the molded structural portion defines a first contact surface;
- and
- a second contact surface on a partition plate that interfaces with at least a region of the first contact surface of the molded structural portion.
