Definitions
- the invention relates to a fuel injector for a Internal combustion engine according to the preamble of claim 1.
- Such a fuel injector on the injection systems Fuel under high pressure in the combustion chamber an internal combustion engine is injected, for example known from EP-B-0 637 686.
- This injector points a nozzle body and a nozzle holder, the intermediate layer a stop washer by means of a nozzle lock nut screwed together.
- a nozzle needle is displaceable in the axial direction guided in the idle state in a valve seat on lower end of the guide bore arranged spray openings seals.
- the guide bore of the nozzle needle is still extended at one point to a pressure chamber, over a Inlet bore fuel is supplied at high pressure.
- the Nozzle needle has a pressure shoulder in the area of the pressure chamber on which the fuel under high pressure attack can.
- a blind hole in the nozzle holder is one of Helical compression springs loaded pressure pin arranged.
- Pressure pin acts via a formed in the stop plate Conduction with the nozzle needle together and presses it at rest with a preset holding force the valve seat in the nozzle body.
- nozzle body exceeds this holding force, raises the nozzle needle from the valve seat and moves axially in the direction on the stopper plate until the end face of the nozzle needle stops at the stop disc and so the maximum stroke the nozzle needle and thus limits the injection quantity.
- the stroke limiter for the nozzle needle are the one another lying surfaces of the stop disc, the nozzle holder and the nozzle body executed exactly plan to for a reliable sealing to the outside against the under one Pressure up to 1500 bar standing fuel to provide. Such Planicity of the adjacent surfaces is however difficult to reach.
- EP-A-0 957 262 is a fuel injection valve for a Common rail fuel injection system with multiple injector modules known, arranged axially one above the other and with a Union nut are axially braced against each other. Make up the two touching faces of two each Overlying injector modules sealing surfaces.
- an injector module For example, a stop element, with a Well of low planicity provided.
- the Recess in the face of the injector module by laser ablation or electron beam ablation produced. Both
- known methods can always only one end face of the injector module are processed individually. This is the result Production process very expensive and therefore expensive.
- the invention is based on the object, a fuel injector to provide at the sealing surfaces on a stop element can be produced quickly and precisely.
- a disc-shaped stopper member which in a region between a nozzle body and a nozzle holder is arranged, on both sides sealing surfaces, each with at least a recess on.
- the recesses are the areas of the two sealing surfaces on the
- Each end of the stop element is reduced, thereby on the one hand, a surface pressure between a nozzle holder section and the first sealing surface opposite thereto and on the other hand between a nozzle body portion and increases the opposite second sealing surface. Due to the compared to an overall end face of the stop element smaller first and second sealing surface is formed when biasing the nozzle holder and the nozzle body against each other a high surface pressure and a high pressure density Connection.
- the respective recess in the first and the second sealing surface is punched and / or embossed according to the invention.
- the manufacturing process for the recess very fast and therefore cost-effective.
- punching is a recess in the stop element can be produced with high accuracy and any shape.
- the manufacture of the recess according to the invention by means of punching and / or embossing it is possible in a manufacturing step To exclude both sealing surfaces at the same time, so that the manufacturing process for the sealing surfaces on the Lifting element considerably simplified.
- the recess is continuous from the first to the second sealing surface through the disc-shaped stop element passes through.
- the two-sided recesses in a simple way by punching the stop element produced. Unlike one For example, milled version of the recesses allows the punching a freer design possibility of Sealing surface geometry with low manufacturing costs.
- the recess is at a predetermined depth respectively formed recessed in the first and second sealing surface.
- the recesses at the first and the second sealing surface for example, by two-sided Embossing will be provided.
- embossing on both sides is again the processing of two sealing surfaces in one Work step ensured.
- the recess has a round, oval or polygonal shape.
- Such contours are quickly and accurately produced by punching.
- Fig. 1 shows a substantially rotationally symmetrical Fuel Injection nozzle in a first embodiment, at a nozzle body 2 through a nozzle lock nut 4 with a Nozzle holder 6 is firmly clamped.
- a first pilot hole 8 in the nozzle body 2 is a nozzle needle 10 in the axial direction slidably guided.

- the pressure chamber 12 is with a formed in the nozzle body 2 high-pressure inlet bore (not shown) connected via the pressure chamber 12 below High-pressure fuel is supplied.
- the nozzle holder 6 has a second guide bore 9, its longitudinal axis with the longitudinal axis of the first guide bore 8 is aligned in the nozzle body 2. Furthermore, in the Wall of the nozzle holder 6 a high-pressure inlet bore, not shown formed, which adhere to the high-pressure inlet bore in the nozzle body 2 connects to supply fuel. In the second guide bore 9 in the nozzle holder 6 is axial slidably provided a pressure pin 16, which with a not shown drive is in an operative connection, which acts on the pressure pin 16 with a desired holding pressure. Such a control can be electromagnetic or piezoelectrically or by a spring device be achieved.
- the pressure pin 16 acts via an intermediary transfer body 18 on the nozzle needle 10, wherein the nozzle needle 10, the pressure pin 16 and the transfer body 18 to achieve arranged aligned axially of a good power transmission are.
- the second guide hole 9 is in the front Area formed a spring chamber 20, in which a spring force adjustment 21 is arranged.
- a spring force adjustment 21 is arranged on the spring force adjusting disc 21 .
- a coil spring 22 with its one End supported.
- the other end of the coil spring 22 acts with an end face of the transfer body 18 together.
- the coil spring 22 is designed so that they over the transfer body 18, the nozzle needle 10 in the unpressurized state, if no fuel pressure in the pressure chamber of the nozzle body 2 is present, presses against the valve seat in the nozzle body 2 and thus prevent fuel injection.
- a disk-shaped stop element 26 Between opposite end faces of the nozzle holder 6 and the nozzle body 2 is a disk-shaped stop element 26 inserted.
- the stop element 26 a central passage 28 through which the transfer body 18 sections as active link between the pressure pin 16 and the nozzle needle 10 extends.
