Compressor

摘要

A compressor may include first and second scrolls, a hub plate and a valve. The first scroll may include an end plate defining first and second sides, a primary discharge passage extending therethrough, and a secondary discharge passage extending therethrough and located radially outward from the primary discharge passage. The hub plate may be mounted to the first scroll and may include first and second opposite sides and a hub discharge passage in fluid communication with the primary discharge passage. The first side of the hub plate may face the second side of the end plate and may include a valve guide extending axially toward the end plate adjacent the hub discharge passage. The valve member may be secured on the valve guide for axial movement between open and closed positions to respectively allow and restrict fluid communication between the secondary discharge passage and the hub discharge passage.

1. A compressor comprising:
a first scroll member including a first end plate defining first and second sides opposite one another, a primary discharge passage extending through said first and second sides, a first spiral wrap extending from said first side, an annular recess in said second side, and a first aperture extending through said first and second sides and in communication with said annular recess; a second scroll member including a second end plate having a second spiral wrap extending therefrom and meshingly engaged with said first spiral wrap to form a series of compression pockets, said first aperture being in communication with one of said compression pockets; and a hub assembly including a hub plate mounted to said first scroll member and including first and second sides opposite one another and having a hub discharge passage extending therethrough and in fluid communication with said primary discharge passage, said first side of said hub plate adjacent said second side of said first end plate, said second side of said hub plate including an annular hub surrounding said hub discharge passage and an annular rim surrounding said annular hub and defining an annular chamber therebetween, a second aperture extending through said hub plate into said annular chamber and fluidly communicating with said annular recess.
