Abstract: PURPOSE: An LPI fuel pump using a fuel distribution pipe is provided to minimize the flow-rate decrease of a fuel pump by immediately removing bubbles from the fuel pump by serially connecting the positive displacement fuel-chamber of the fuel pump using the fuel distribution pipe. CONSTITUTION: An LPI fuel pump using a fuel distribution pipe comprises a plurality of fuel chambers, a relief valve and a fuel distribution pipe(40). The fuel chamber can temporarily store fuel. The relief valve cancels abnormal high-pressure in the fuel pump(10). The fuel distribution pipe comprises an intake part(41) and a plurality of discharge parts(42). One end of the fuel distribution pipe is connected to a fuel tank to form the intake part so that liquid fuel flows into the fuel distribution pipe. The other end of the fuel distribution pipe is connected to the fuel chambers and the relief valve to form the discharge parts so that the liquid fuel is supplied to the inside of the fuel pump.

Abstract: A shutoff valve for preventing fuel from leaking in a vehicle is provided to inject fuel smoothly by minimizing the resistance pressure against fuel injection and to improve tightness by using a rubber seal in order to prevent fuel leakage. A shutoff valve includes a valve housing(10), a valve(11), a spring(13), and a seal(14). The valve housing has a step with a curved surface. The vale includes a valve body(11a) integrally formed with a valve stem(11b). The valve body has a funnel shape. The spring surrounds the valve stem to support the valve elastically. The seal is mounted on the outer peripheral surface of the valve body. The seal has a curved surface to stick to the step.

Abstract: An LPG supply system of a liquefied petroleum injection engine is provided to prevent intrusion of foreign substances into the system and to absorb noise of a fuel pump. An LPG supply system of a liquefied petroleum injection engine includes a liquefied petroleum injection engine(50), a main bombe(52), a sub bombe(54), and a fuel pump(56). The liquefied petroleum injection engine is operated by receiving LPG fuel. The main bombe stores a large amount of LPG fuel to drive the liquefied petroleum injection engine. The sub bombe is installed between the main bombe and the liquefied petroleum injection engine to store a small amount of LPG fuel. The fuel pump is installed in the sub bombe to pump the LPG fuel in the main bombe to the liquefied petroleum injection engine. A first fuel supply line and a first fuel return line are arranged between the liquefied petroleum injection engine and the sub bombe.
