Abstract
A compressor may include a scroll member, a hub, a discharge valve and a bypass valve. An end plate of the scroll member includes a recess, a discharge passage in communication with the recess, and a bypass passage in communication with the recess and disposed radially outward relative to the discharge passage. The hub may be received in the recess and may include a central opening in communication with the discharge passage and the bypass passage. The discharge valve may be disposed between the hub and the end plate and may control fluid flow through the discharge passage. The bypass valve may be disposed between the hub and the end plate and may be movable between a first position restricting fluid flow through the bypass passage and a second position allowing fluid to flow through the bypass passage, around the discharge valve and through the central opening.
