Filed:

Apr 23, 2007

Appl. No.:

11/788884

Inventors:

Michael Brown - Phoenix AZ, US
John Lockhart - Cave Creek AZ, US
Jeff Doss - Scottsdale AZ, US

International Classification:

G05D 23/02

US Classification:

236 93A, 236 99 K

Abstract:

A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.
