Abstract

Provided is a reversing valve that can reverse flow in a refrigeration system. The reversing valve includes a valve body extending between a first end and an opposing second end. Multiple ports are disposed through the first and second ends. In one aspect, to reduce the pressure drop across the valve body, flow is channeled generally straightly between the ends. This is accomplished by a valve member defining a channel that is coupled to a port at the first end while pivotally movable to intersect different ports at the second end. Flow direction in the system is determined by which port at the second end is intersected. In another aspect, to move the valve member, the reversing valve includes a permanent magnet joined to the valve member and an electromagnet extending partly around the valve body. Applying different polarities to the electromagnet moves the permanent magnet and the valve member.
