  • Scroll Compressor With Center Hub
    Publication number: 20240052836
    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.
