Abstract

PURPOSE: To prevent danger that a large amount of fuel is released through a main valve, by detecting the pressure at the outlet port of a pilot valve to open an attached valve and then open the main valve when the detected pressure is higher than a prescribed level.
CONSTITUTION: A passage 138 provided with an orifice 136 communicate with the inlet port 104 of an electromagnetic throttle valve 70 which communicates with the inlet chamber 72 of a main flow rate regulation valve 68. When the leak from the valve 68 or 70 is larger than the quantity of pressurized gas supplied from the orifice 136, the diaphragm chamber 130 of a fail-safe valve 114 is not pressurized and a force for pushing a diaphragm 126 against spring 124 is not caused, so that a valve element 122 remains in contact with a valve seat 120 and the fail-safe valve 114 is not opened. For that reason, a diaphragm chamber 54 is not pressurized. Consequently, a main open/close and pressure control valve 52 remains closed. This results in pre venting a danger that a large amount of fuel is released through the main valve 52.
