Abstract

A compressor may include a shell assembly defining suction and discharge pressure regions, first and second scroll members disposed within the shell assembly, and a capacity modulation assembly. The first scroll member may include a first end plate defining a discharge passage, a biasing passage, a modulation port, a first spiral wrap extending from a first side of the first end plate, and an annular hub extending from a second side of the first end plate. The second scroll member may include a second spiral wrap meshingly engaged with the first spiral wrap forming a suction pocket in communication with the suction pressure region, intermediate compression pockets, and a discharge pocket in communication with the discharge passage. A first intermediate compression pocket may be in communication with the biasing passage and a second intermediate compression pocket may be in communication with the modulation port.
