Abstract
A household type refrigerator has a refrigeration system including a subcooling flow control valve placed between the outlet of the condenser and the inlet to the capillary tube. The subcooling flow control valve utilizes a sealed capsule of refrigerant which operates to open and close a valve to modulate the flow from the condenser to the capillary tube to insure only that a subcooled liquid enters the capillary. The valve is mounted vertically next to the compressor and has the inlet line to the valve secured in heat conducting contact to the return line to the compressor for faster opening and closing response while the discharge side of the valve has a chamber filled with a plug to minimize the volume of refrigerant remaining between the closed valve and the entrance to the capillary when the compressor is on the off cycle.
