Abstract:
1. A control device for regulating delivery of fuel comprising: an inlet; an electromagnetic safety valve, having a thermocouple connection; a control valve, wherein the electromagnetic safety valve selectively allows fuel to flow from the inlet to the control valve through the electromagnetic safety valve when the thermocouple connection is heated; an actuator valve; a first conduit that is in fluid communication between the control valve and the actuator valve; a main valve having a pressure responsive device, having a first side and a second side and including an outlet chamber; a second conduit that is in fluid communication between the actuator valve and the second side of the pressure responsive device for the main valve; a regulator valve having a sensing port and an outlet; a third conduit that is in fluid communication between the outlet chamber of the main valve and the sensing port of the regulator valve; a fourth conduit that is in fluid communication between the outlet of the actuator valve and the first side of the pressure responsive device for the main valve; a fifth conduit that is in fluid communication between the control valve and the main valve; an outlet; and a sixth conduit that is in fluid communication between the outlet chamber of the main valve and the inlet, wherein fluid can flow from the inlet to the outlet when the electromagnetic safety valve, the control valve and the main valve are open.
