ABSTRACT:
A refrigerant flow reversing valve includes a tubular valve body defining ports for respectively communicating with the discharge of a refrigerant compressor, the compressor inlet and with heat exchangers in the refrigeration system. A valving member is supported by the body for movement with respect to the ports so that in one valving member position refrigerant flows through the heat exchangers in one direction and in a second valve member position refrigerant flows in the opposite direction through the heat exchangers. Refrigerant flow tubes are hermetically fixed to the reversing valve body for directing refrigerant flows through the valve from the refrigeration system. Heat transfer is blocked immediately adjacent the valve body for minimizing heat flow between the valve body and refrigerant in the flow tubes adjacent the valve body.
