GAS FEEDING APPARATUS OF GAS FUEL VEHICLES

摘要

PURPOSE: A gas feeding apparatus of gas fuel vehicles is provided to improve startability by remaining liquid fuel in a feed pipe when a vehicle stops for a long time. CONSTITUTION: A gas feeding apparatus of gas fuel vehicles includes a fuel feed line consisting of a base plate(110) installed in a fuel tank, a check valve on a multi-valve(100) constituted of a valve block(120) formed on one face of the base plate, an overflow preventing valve, a manual valve(128), a first opening and closing valve(132), and a feed pipe(140). The fuel feed device includes a bypass line consisting of a bypass path(152) and a relief valve. If the pressure of the fuel in the feed pipe becomes lower than 8 bar, the relief valve is closed. Thus, the fuel is not bypassed and remaining in the valve block and the feed pipe.
