Abstract: PURPOSE: A link-type fuel pump for a gas fuel vehicle is provided to reduce the number of assembling processes since the number of pump chambers, which perform the suction and the discharge of fuel, are reduced. CONSTITUTION: A link-type fuel pump for a gas fuel vehicle comprises a motor unit(M), a pump unit(P) and a fuel discharge unit. The motor unit comprises a rotor(R) and a stator(12), which are connected to a shaft, in motor case. The pump unit converts the rotating movement of the shaft to linear movement. The pump unit comprises diaphragm assembly, which generates the pressure difference in a fuel chamber(FC) and practices a pumping operation. The fuel discharge unit discharges the fuel, which has been discharged from the pump unit. The diaphragm assembly comprises an eccentric cam, a link shaft and a diaphragm. The eccentric cam is eccentric-connected to the bottom of the shaft and comprises a plurality of holders on the outer circumferential surface.

Abstract: PURPOSE: An in-tank type pump is provided to reduce manufacture cost using a swash plate and a diaphragm instead of an eccentric shaft. CONSTITUTION: An in-tank type pump comprises a motor unit(11) and a pump unit(15). The motor unit rotates a shaft(13) to pump fuel stored in a fuel tank. The pump unit pumps fuel by receiving the rotational motion of the shaft. The pump unit forms intake pressure and the exhaust pressure of the fuel. The pump unit comprises a first cover, a body portion(17), and a second cover(18). The first cover forms the intake pressure and exhaust pressure by the rotational motion of the shaft.

Abstract: PURPOSE: A liquefied petroleum injection system for a gas vehicle is provided to improve durability by including a lifting unit which lifts a vent hole to prevent the vent hole from being soaked in the liquid when gas fuel is overcharged. CONSTITUTION: A liquefied petroleum injection system for a gas vehicle comprises a bombe, a pump, a vent hole(P-3), and a vent hole lifting unit(A1). The gas fuel is saved in the bombe. The pump is installed inside the bombe and transmits the gas fuel. The vent hole is formed at the end of the hose(P-2) connected to the discharge side of the pump. The vent hole lifting unit is positioned on the upmost layer of bombe by lifting a vent hole upward. The vent hole lifting unit comprises a fixing member, an axis pin, a bracket, an elastic unit, and a pipe. The fixing member has one side formed with a fixing hole and the other side formed with a connection part. The axis pin is connected to the connection part of the fixing member. The bracket is inserted into the axis pin. The elastic unit is coupled with the axis pin and applies the elastic force to the bracket.
