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.
Claims4
A multiport diverter valve comprising a valve housing defining a valving chamber therein, a plurality of ports opening into said chamber, said flow diverter pivotally mounted in said chamber, said flow diverter having a concave diverter surface forming a portion of a torus, first and second ends of said torus communicating with a first adjacent pair of said ports to provide a flow path only between the adjacent pair while blocking flow to another port, means to pivot said diverter to a position connecting a second adjacent pair of said ports to provide a flow path only between said second adjacent pair while blocking flow to another port, said second pair including one of said ports from said first pair, said diverter being movable to a position simultaneously connecting all of said parts.
A multiport diverter valve comprising a valve housing including a cover defining a chamber, a plurality of ports opening into said chamber, a flow diverter pivotally mounted in said chamber, said flow diverter being defined by concave and convex surfaces forming a portion of a torus, an operating handle connected to said flow diverter, first and second ends of said torus communicating with a first adjacent pair of said ports when said handle is in a first position to provide a flow path between the first adjacent pair, said first and second ends of said torus communicating with a second adjacent pair of said ports when said handle is in a second portion to provide a flow path between the second adjacent pair, said second pair including one of said ports from said first pair, said handle being moveable to a third position to pivot said diverter to a position wherein the concave surface of said diverter does not connect any of said ports and the convex side of said diverter connects all of said ports.
