ABSTRACT:
A multiport diverter valve comprising a valve housing defining a valving chamber therein. A plurality of ports open into the chamber. A flow diverter is pivotally mounted in the chamber and has a concave diverter surface forming a portion of a torus. First and second ends of the torus communicate with a first adjacent pair of the ports to provide a flow path between the adjacent pair. A valve handle is adapted to pivot the diverter to a position connecting a second adjacent pair of the ports with the second pair of ports including one of the ports from the first pair. The handle is further adapted to pivot the diverter to a position connecting all of the ports.
