    摘要： Disclosed herein is a two-stage fuel injection valve for a diesel engine. The valve includes a fuel valve block (110) having therein a passage (1701) into which fuel is supplied; a nozzle (140) having a low pressure nozzle hole (160) and a high pressure nozzle hole (161); a needle valve (130) differentially opening the low pressure nozzle hole and the high pressure nozzle; pressure booster spindles (141), (142) and (143) pressurizing the needle valve to boost pressure of low-load fuel; a shuttle valve (150) configured to supply a gauge pressure to the pressure booster spindles, thus raising the pressure of the fuel; a lifting bush valve (180) discharging fuel to a fuel discharge hole through a gap between the fuel discharge hole and a nozzle holder when a solenoid valve (201) is moved upwards; and the solenoid valve (201) controlling pressure applied to the lifting bush valve.

    摘要： The fuel injector (44, 66, 70, 74) for an internal combustion engine, particularly of the inwards or outwards opening needle injector type, comprises an injector body (12) which in particular forms a nozzle (16) ending in an injection orifice, means for closing off the said injection orifice of the said injector body, the said closing-off means comprising a vibrating pintle (24) ending in a head (26) for closing off the said injection orifice, return means (30) for returning the said closing-off means to the position in which they close off the said injection orifice, and means (36, 72) for setting the said pintle (24) and/or the said nozzle (16) into cyclic longitudinal vibration so as to open and close the injection orifice alternately. The fuel injector (44, 66, 70, 74) is notable in that it comprises selectively activatable means (46, 48) for immobilizing the said pintle (24) with respect to the said body (12).

    摘要： The invention concerns a fuel injection device for internal combustion engine. The fuel injection device for internal combustion engine comprises an injecting head integral with the end of a needle (3) mobile in translation inside an injection housing (4) supplied with high pressure fuel and having a seat for the injecting head, and a piezoelectric or magnetoresistive vibratory element (5) capable, when it is energized, to act on the needle (3), maintained by a return spring (10), to cause same to vibrate, such that the injecting head co-operates with its seat to periodically open and close a passage for fuel injection. The device comprises means for controlling (16, 17) the movement of the needle in translation, countering the return spring (10), independent of the vibratory element (5).

    摘要： The invention relates to a fuel injection valve which comprises a housing (1) with a valve seat (20) configured therein and an interior valve needle (17) and an exterior valve needle (15). The pressure in an exterior control chamber (56) exerts a closing force onto the exterior valve needle (17) and the pressure in an interior control chamber (54) exerts a corresponding closing force onto the interior valve needle (15). The interior control chamber (54) is linked with a control valve chamber (60) of a control valve (30) via an interior outlet throttle (51) and the exterior control chamber (56) via an exterior outlet throttle (49), a valve member (62) being disposed in said control valve chamber (60). The interior control chamber (54) is linked with a high-pressure area (8) via an interior inlet throttle (47) and the exterior control chamber (56) via an exterior inlet throttle (45). The valve member (62) can assume a first, a second and a third switched position so that the pressure in the control chambers (54; 56) can be controlled to open only the exterior valve needle (17) as well as both valve needles (15; 17).

    摘要： A control valve assembly for use in a pump or injector of fuel injection valves is provided. A pump (10) or injector body has a pumping chamber (16), and a valve chamber (22). The valve chamber (22) defines a valve seat (72) and has an axial guiding portion. A plunger (30) is disposed in the pumping chamber (16). A valve body (48) disposed in the valve chamber controls fuel. The valve body (48) has a valve stem defining a seating surface. The valve body further has a valve guide in sliding engagement with the valve chamber guiding portion. The valve body is axially movable with respect to the valve chamber over a stroke range. The valve guide has an outer engagement surface that slidingly engages the valve chamber guiding portion with a clearance fit of at least about 5 micrometers in one embodiment. In another embodiment, the axial length of the engagement surface is at most about 7 millimeters. The reduced axial length and/or the clearance fit improve initial sealing performance and sealing performance over the life cycle of the product.
