Abstract: A compressor may include non-orbiting and orbiting scrolls, a hub plate, and primary and secondary discharge valve assemblies. The non-orbiting scroll includes a first end plate having primary and secondary discharge passages. The hub plate may be mounted to the non-orbiting scroll and may include a main body and a central hub extending axially from the main body. The central hub may include a recess and a hub aperture. The primary discharge valve assembly may include a retainer and a primary valve member. In a closed position, the primary valve member may restrict fluid flow between the discharge chamber and the primary discharge passage. The secondary discharge valve assembly may include a secondary valve member that selectively allows and restricts fluid communication between the secondary discharge passage and the hub aperture of the central hub.

Abstract: A compressor may include an orbiting scroll, a non-orbiting scroll, and suction conduit. The non-orbiting scroll is meshingly engaged with the orbiting scroll and includes a lower scroll piece and an upper scroll piece that is mounted to the lower scroll piece. The suction conduit is mounted to the non-orbiting scroll. The suction conduit includes an inlet, an outlet, and a mounting flange. The outlet is disposed adjacent to and in fluid communication with a suction inlet of the non-orbiting scroll. At least a portion of the mounting flange is captured between the upper and lower scroll pieces.

Abstract: A compressor includes first and second scroll members and a bearing housing. The first scroll member includes a first end plate and a first scroll wrap. The second scroll member includes a second end plate that has a first surface, a second surface, and an oil passage. The first surface has a second scroll wrap meshingly engaging the first scroll wrap. The second surface includes an oil aperture. The oil passage is in fluid communication with the oil aperture. The bearing housing cooperates with the second scroll member to define an interior volume. Lubricant in the interior volume is selectively allowed to flow into the oil passage via the oil aperture.

The bearing housing cooperates with the second scroll member to define an interior volume. The second scroll member is movable between a first position in which lubricant in the interior volume is allowed to flow into the oil passage via the oil slot, and a second position in which working fluid in the chamber is allowed to flow into the oil passage via the oil slot.

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.
