ABSTRACT:
A diverter-type mixing valve has a body formed with a chamber having opposite ends, a mixed-water feed passage opening into the chamber between its ends, a faucet outlet port opening into the chamber at one end thereof, a vent port opening into the chamber at the other end thereof, a diverter port also opening into the chamber at the other end thereof, and a restriction in the chamber between the feed passage and the ports at the other end. Mixed water is supplied under pressure to the feed passage. A diverter valve in the chamber directs flow from the feed passage out the faucet port when pressure between the restriction and the other end is greater than pressure between the restriction and one end and directs flow from the feed passage to the diverter port when pressure between the restriction and one end is greater than pressure between the restriction and the other end. A one-way vent valve in the vent port only permits flow through the vent port into the chamber and a one-way check valve associated with the diverter port only permits flow through the diverter port out of the chamber.
