摘要： A fuel injector (1) for fuel injection systems of internal combustion engines includes a valve needle (3) and a valve closing body (4) which is mechanically linked thereto and cooperates with a valve seat surface (6) situated in a valve seat body (5) to form a sealing seat, and having a plurality of discharge orifices (7), which are introduced in a spray-orifice disk (31), which is situated downstream from the sealing seat on the fuel injector (2). The spray-orifice disk (31) has a dome-shaped convexity (37) at least in the area of the discharge orifices (7), which is oriented against the direction of flow of the fuel and the discharge orifices (7) are arranged in a spiral on the dome-shaped convexity (37) of the spray-orifice disk (31).

摘要： The invention relates to a fuel injection valve for fuel injection systems of internal combustion engines, comprising a valve needle (3) and a valve closing body (4) functionally linked therewith that interacts with a valve face (6) disposed in a valve seat body (5) to give a sealing seat. A plurality of recesses (34) are provided downstream of the sealing seat in the valve seat body (5). An orifice plate (31) is disposed downstream of the valve seat body (5) and is provided with at least one spray orifice (7) per recess (34). The cross-section of said spray orifice is smaller than that of the recess (34) and disposed in such a manner that its inlet cross-section lies completely within the outlet cross-section of the respective recess (34).

摘要： The injection valve has a swirl-generating device (34) with helical winding (35), which together with an aperture (39) in the valve seat body (5), forms a fuel channel (38). The channel feeds fuel along a spiral path to an ejection aperture (7). The swirl device is located on the intake side of the valve seat, and the valve closure body (4) extends through the swirl device. The device may be formed by a pre-tensioned helical spring, and the fuel channel is formed between the spring and an inner wall (40) of the valve seat body aperture.

摘要： The invention relates to a fuel injection valve (1), in particular, for directly injecting fuel into a combustion chamber of an internal combustion engine. Said fuel injection valve comprises an actuator (10) for actuating a valve needle (3), whereby the valve needle (3), at a spraying end, has a valve closing body (4) that, together with a valve seating (6), which is provided on a valve seat body (5), forms a tight seat. Fuel channels (35) that lead into a turbulence chamber (43) are arranged inside a valve needle guide (31), which is connected to the valve seat body (5) or provided therewith as one piece. The number of fuel channels (35) is calculated as to render a turbulent flow, which is generated in the turbulence chamber (43), homogeneous in a peripheral direction.

摘要： The invention relates to a fuel-injection valve for fuel-injection systems of internal combustion engines, which among other things comprises an actuator (10, 11, 12) and a displaceable valve part (5, 7) that co-operates with a fixed valve seat (22) configured on a valve seat body (16) to open and close the valve. A disc-shaped swirl element (25), which has both at least one inlet zone (27) and at least one outlet opening (29), is located downstream of the valve seat (22). Said swirl element has at least one swirl channel (28), positioned upstream of the outlet opening (29). The incoming flow is received centrally by the inlet zone (27) in the swirl element (25). Several swirl channels (28) run from said inlet zone, which permits a swirling characteristic to be imposed on the fuel that traverses the swirl channels (28) exclusively in a radial direction from the interior towards the exterior. The fuel-injection valve is particularly suitable for use as a high-pressure injection valve for directly injecting fuel into the combustion chamber of compressed-mixture, spark-ignition internal combustion engines.

摘要： A fuel injection valve (31, 48), especially an injection valve for fuel injection systems of internal combustion engines, has an actuator which interacts with a first valve needle (35, 52). A first valve-closing body (36, 53) which is located on said first valve needle (35, 52) interacts with a first valve seat surface (37, 54) to form a first sealed seat (38, 55). A second actuator interacts with a second valve needle (39, 56), a second valve closing body (40, 57) which is located on the second valve needle (39, 56) interacting with a second valve seat surface (41, 58) to form a second sealed seat (42, 59).

摘要： PCT No. PCT/DE95/00523 Sec. 371 Date Oct. 30, 1996 Sec. 102(e) Date Oct. 30, 1996 PCT Filed Apr. 13, 1995 PCT Pub. No. WO96/10694 PCT Pub. Date Apr. 11, 1996The nozzle plate according to the present invention includes an axial passage for a fluid, particularly for a fuel, which is made up in the downstream direction by a filter, a ring chamber and an uninterrupted ring gap following one another. Using this arrangement, a cohesive tulip-shaped jet lamella can be produced which thins out in the downstream direction and then disintegrates into tiny droplets. As a consequence, the exhaust emission of an internal combustion engine can be further reduced and likewise a reduction of the fuel consumption can be achieved. The nozzle plate is suited particularly for injection valves in fuel injection systems of internal combustion engines with externally supplied ignition which compress the mixture.

摘要： The invention relates to a fuel injector for fuel injection systems of internal combustion engines, comprising two pre-assembled independent modules, namely a functional part (30) which essentially comprises an electromagnetic circuit (1, 2, 5) and a sealing valve (15, 19), and a connecting part (40) which consists primarily of a hydraulic connector (42, 43) and an electrical connector (55, 56, 57). In the fully assembled injector electrical connecting elements (34, 59) and hydraulic connecting elements (28, 43) of the two modules (30, 40) cooperate such as to ensure a reliable electrical and hydraulic connection. An over-moulding (60) in the area of the connection ensures the mechanical connection of the two modules (30, 40), a high injector stability and sufficient tightness. This fuel injector is especially well suited for use in fuel injection systems of mixture-compressing, spark-ignited internal combustion engines.

摘要： The invention relates to a swirl disk characterized in that it consists of at least one metallic material, has at least one inlet area (65) and at least one outlet opening (69) which is embodied in a lower base layer (62), and at least two swirl channels (66) which discharge into a swirl chamber (68). The swirl chamber (68) is situated in a middle swirl-generating layer (61). An upper layer is configured as a covering layer (60) which across its entire cross-sectional area is a continuous layer without opening outlines. All layers of the swirl disk (30) are placed directly on top of each other by means of galvanic metallisation (multilayer galvanic metallisation). This swirl disk (30) is especially suitable for use in a fuel injection valve, especially a high-pressure injection valve for the direct injection of fuel into a combustion chamber of a spark-ignition internal combustion engine with mixture compression.
