Title: Refrigeration heat pump changeover valve assembly

Abstract

A refrigeration heat pump changeover valve assembly has a cylindrical housing with a slidable valve member in the housing for changing the flow of refrigerant in a refrigeration heat pump system. The evaporator and condenser lines are connected on one side of the housing adjacent each other in line with the axis of the housing. The compressor suction line and discharge or pressure line are connected on the other side of the housing opposite the evaporator and condenser lines adjacent each other at right angles to the axis of the cylindrical housing. The valve member upon moving between a first and a second position upon the operation of a pilot valve connects the suction line to either the evaporator or condenser line when in the first or second position, respectively, and the discharge line is connected to the other line. The valve assembly provides for low pressure drop , straight through flow of the refrigerant into the suction line and from the discharge line to either the evaporator or condenser lines depending upon the operation of the self-contained pilot valve system.
