Abstract

A capacity control for a multi-cylinder refrigeration compressor (20) includes a modulating valve (40) disposed between a suction manifold (34) and less than all of the cylinders (30) of the refrigeration compressor (20). The modulating valve (40) regulates the flow of refrigerant gas from the manifold (34) to the cylinders (30) in communication therewith, with the valve (40) functioning to increase the flow of refrigerant gas to the cylinders (30) as the load on the refrigeration unit (10) increases and to decrease the flow of refrigerant as the load on the refrigeration unit (10) decreases.
