CONSTITUTION: An integral valve for a fuel tank of a gaseous fuel vehicle comprises an integral housing(51) installed outside a fuel tank to keep airtightness, a valve assembly for feeding fuel installed in the integral housing, a valve assembly for exhausting fuel(58) formed in the integral housing, a return oil passage, and a fuel gauge installed in the integral housing. The valve assembly for fuel feed is equipped with an overcharge prevention valve and a float(53) interlocking with the over charge prevention valve. The valve assembly for exhausting fuel has a reverse flow-preventing check valve(56) and an overflow-preventing valve(57) to the outlet side exhausting fuel from the fuel tank to the engine side by the operation of a fuel pump(55). The return oil passage returns some of fuel from the engine to the fuel tank and has a reverse flow-preventing check valve(59) within. The fuel gauge indicates the residual amount in the fuel tank.

Abstract: PURPOSE: A fuel supply apparatus of a gas fuel vehicle is provided to reduce parts, and to improve safety against gas fuel leakage by eliminating a recovery system and connecting plural injectors mutually with a rail module. CONSTITUTION: A fuel supply motor pump(21) is installed in a fuel tank(20) storing fuel to supply liquid fuel and discharge. Fuel gas is returned to the fuel tank in case of pressure of fuel gas to be over the reference value in passing through a gas fuel discharge pressure adjusting unit(22). Gas fuel is streamed from the gas fuel discharge pressure adjusting unit through a gas supply pipe(23) to a rail module(24). Plural injectors(242) injecting gas fuel to an engine and a pressure sensor(244) detecting pressure of gas fuel are installed in the rail module. An ECU(Electronic Control Unit)(25) sets opening and closing time of injectors according to pressure, opens and closes plural injectors in driving the engine, and controls the motor pump.
