GAS FEEDING APPARATUS OF GAS FUEL VEHICLES

摘要

A gas feeding apparatus of gas fuel vehicles is provided to enable a user to simply/easily repair or replace a fuel pump by separating a fuel pump only from a supplying pipe after blocking a bombe and the supplying pipe through an opening/closing valve. A gas feeding apparatus of gas fuel vehicles includes a bypass pipe(400), a valve block(300). The bypass pipe is installed so as to connect a supplying line between a fuel pump(200) and a regulator unit(500) and a bombe(100), and bypasses a fluid gas fuel in a supplying pipe(110) to the bombe. The valve block is installed at a connection portion between the bypass pipe and the supplying pipe, prevents flowing backward of the supplied fluid gas fuel, and bypasses the supplied fluid gas fuel to the bombe through the bypass pipe when pressure of the supplying pipe increases. The valve block includes a body and a projection. The body is connected to the supplying pipe and includes a cavity. The bypass pipe is installed at the protrusion of the valve block to connect the valve block to the bombe. A check valve(320) is installed on one side of the body. And, a relief valve(330) is installed at the protrusion connected thereto the bypass pipe.
