Abstract (en)
The fuel injection device easily sets the full lift position of the valve assembly and assures stable lift of the control piston(2) without being affected by pulsations of the fuel pressure in the balance chamber(35). In this fuel injection device, the valve assembly comprises a control piston(2) inserted into the control sleeve(7) and a needle valve(3) that opens and closes the nozzle holes(50). The end surface(75) of the control piston(2) is provided with a projecting portion(71) that projects into the balance chamber(35) formed in the control sleeve(7). In an area of the exhaust passage(26) in the control sleeve(7) a projecting portion(70) is provided which is formed with a slit(72) opening to the balance chamber(35) at all times. The end surfaces(77, 76) of these projecting portions(71, 70) engage with each other when the control piston(2) reaches its full lift. <IMAGE> <IMAGE>
