Abstract
A compressor may include a shell defining an internal volume containing compressed working fluid and first and second scrolls disposed within the internal volume. The first scroll may include a first spiral wrap. The second scroll may include a second spiral wrap, a suction inlet opening and a capacity-modulation aperture. The second spiral wrap may engage the first spiral wrap to define a pocket therebetween. The suction inlet opening may be sealed off from the internal volume. The capacity-modulation aperture may receive a valve member that is movable between a first position allowing leakage of fluid from the pocket to the suction inlet opening and a second position restricting leakage of fluid from the pocket.
