Abstract
A compressor may include first and second scrolls and a capacity modulation assembly. The capacity modulation assembly may include a valve ring and a modulation control valve. The valve ring is movable relative to the first scroll between a first position corresponding to a first capacity mode and a second position corresponding to a second capacity mode. The modulation control valve includes a valve body and a valve member that is movable relative to the valve body to cause corresponding movement of the valve ring. The valve body includes a cavity in which the valve member is movably disposed. The valve body includes passages in fluid communication with the cavity. A first pressure differential between fluid in one of the passages and fluid in another of the passages causes movement of the valve member to cause corresponding movement of the valve ring between the first and second positions.
