COMBINED GAS PRESSURE REGULATOR AND SHUT OFF VALVE Abstract of The Disclosure A gas stove (A) includes a combined pressure regulator and manual shut off valve (C) which has an inlet (46) connected with a source (B) of natural gas. The combined valve includes a pressure regulator (60) in fluid communication with the inlet through a regulating valve assembly (64, 66). The regulating valve assembly which controls the flow of gas to a regulator chamber (62) is controlled by a diaphragm (68) and a spring (70) to maintain the pressure in the chamber substantially constant. A first outlet (48) is connected by a passage (72) directly with the regulator chamber for supplying pressure regulated gas to a plurality of range burner control valves (20) and range burners (22). A poppet valve (80) having only two stable states, fully open and fully closed, is connected between the regulator chamber and a second outlet (50). A manually graspable lever (52) and a cam member (80) enable the state of the poppet valve to be controlled. The second outlet is connected with an oven assembly including an electrically operated oven gas supply valve (30) which supplies gas to an oven burner (32) under the control of a temperature monitor (34).
