Abstract

A refrigerant flow control assembly for metering the flow of refrigerant, under low load and normal operating conditions, from the high pressure side to the low pressure side of refrigeration machine. The assembly includes a valve plate defining a circular port for the flow of refrigerant therethrough. A valve plug is provided having a conical surface at one end for communication with the circular port, and a stem at the other end. A valve plug support is operatively connected to the valve plate for mounting thereon the valve plug for slidable movement between a closed position and an open position along a line coincident with the axis of the valve plug, which line is perpendicular to and intersects the plane of the circular port at its center. At the closed and open positions, the valve plug defines annular ports, the respective areas of which are determined by an operating characteristic of the refrigeration machine, for passing therethrough gaseous and liquid refrigerant under low load and normal operating conditions.
