Abstract:
1. A reversing valve comprising: a tubular valve body defining an internal chamber, the valve body including a first, second, third, and fourth port disposed therein; a valve member defining a channel for providing a flow path between a selectable pair of the second, third or fourth ports, the valve member including a flow splitter dividing the channel into a plurality of sub-channels, the valve member proximate to and movable with respect to the second, third, and forth ports; an actuator reciprocally movable inside the valve body and engaging the valve member; whereby, when the actuator is moved to a first position, the channel intersects the second and third ports thereby establishing fluid communication between the second and third ports while simultaneously allowing fluid communication between the first and fourth ports via the internal chamber; and whereby, when the actuator is moved to a second position, the channel intersects the second and fourth ports thereby establishing fluid communication between the second and fourth ports while simultaneously allowing fluid communication between the first and third ports via the internal chamber.
