- the invention relates to a high-pressure fuel system for Internal combustion engines from, as it is from the published application DE 198 27 628 A1 is known.
- a high pressure fuel system as in this document in the form of a Fuel injection valve is a valve holding body and a valve body in place by a tension nut be pressed together. Through the contact surface of the an inlet channel passes through both bodies, through which Fuel under high pressure to the injection ports of the Fuel injector arrives. To ensure the tightness of the inlet channel when passing through the contact surface of the two To ensure bodies are on one of the contact surfaces of the raised both body areas, in particular surround the passage of the inlet channel.
- the clamping nut With the same tightening torque the clamping nut turns the surface pressure in this area increases so that there is better sealing of the inlet channel results.
- the known high-pressure fuel system however, the disadvantage of that training such raised areas is relatively complex and therefore costly.
- the high-pressure fuel system according to the invention with the characteristic In contrast, features of claim 1 the advantage that a between the two high pressure bodies Sealing film is arranged, the passage of the channel surrounded by the contact surface and so in a simple and inexpensive Way leads to a seal.
- the sealing film can be designed so that they next to the inlet channel also further penetrations of channels and holes surrounds that are formed in the high-pressure fuel system are.
- the sealing film can be manufactured separately and for example punched out of a corresponding plate be so that it is easy and inexpensive to manufacture.
- the formation of the invention is particularly advantageous Sealing film on a fuel injector where the sealing film between a high-pressure body Valve holding body and a high-pressure body Valve body is arranged.
- the sealing film is made of a metal.
- This metal is preferably soft compared to steel, from which the two high pressure bodies are made.
- Copper or soft iron has been found to be an advantageous material the sealing film proved.
- the sealing film preferably has a thickness in the range of a few ⁇ m up to a few hundred ⁇ m. This can the sealing effect and the flow properties of the sealing film optimal when bracing the two high pressure bodies against each other be matched to the desired tightness.
- FIG. 1 shows an exemplary embodiment of a High-pressure fuel system shown in longitudinal section.
- the high pressure fuel system here is a fuel injection valve, which has a housing that has two high pressure bodies, a valve holding body 1 and a valve body 10 includes.
- the valve body 10 is by means of a clamping nut 12 axially clamped against the valve holding body 1, see above that the two bodies 1.10 touch in a sealing surface 14.
- a bore 8 is formed in the valve body 10, in which a piston-shaped valve needle 16 is longitudinally displaceable is arranged.
- the valve needle 16 faces its combustion chamber End a valve sealing surface 25 which with a trained at the end of the bore 8 facing the combustion chamber Valve seat 23 cooperates and so on their longitudinal movement controls the opening of at least one injection opening 27, which is formed on the valve seat 23.
- the valve needle 16 has a pressure shoulder 13 which faces the combustion chamber is directed and which is surrounded by a pressure chamber 11, by a radial expansion of the bore 8 in the valve body 10 is formed.
- the pressure chamber 11 is one formed in the valve body 10 and in the valve holding body 1 Inlet channel 20 with one not shown in the drawing High pressure fuel source connected so that the pressure chamber 11 be filled with fuel under high pressure can.
- valve needle 16 goes in a pressure pin 7, which in a in the valve holding body 1 designed spring chamber 3 coaxial to the valve needle 16 is arranged to be longitudinally displaceable.
- spring chamber 3 arranged to generate a closing force on the valve needle 16, which are here in the form of a closing spring 5, which between the pressure pin 7 and the combustion chamber facing away End of the spring chamber 3 arranged under pressure is, so that the valve needle 16 by the closing spring 5 in Closing direction is applied.
- valve piston 18 Goes away from the combustion chamber the pressure pin 7 in a valve piston 18, which in a piston bore 17 formed in valve holding body 1 is arranged to be longitudinally displaceable and by means of a the drawing, not shown, a closing force can be exerted on the valve needle 16.
- a closing force can be exerted on the valve needle 16.
- This closing force is caused by the valve needle 16 Pressure in the pressure chamber 11 and the associated hydraulic Force on the pressure shoulder 13 in the opening direction, i.e. from Combustion chamber away, moved or by the closing force of the valve piston 18 with the valve sealing surface 25 on the valve seat 23 pressed so that the injection openings there 27th be closed.
- the valve holding body 1 designed as a high-pressure body lies with a contact surface 101 on the valve body 10 trained contact surface 110.
- Figure 2 shows the area the contact surfaces of valve holding body 1 and valve body 10 in an exploded view.
- a sealing film 35 is arranged, so is designed so that it the passages of the inlet channel 20th and centering pin bores 32 through the sealing surface 14 surrounds.
- In the centering pin bores 32 are centering pins 30 arranged, both in the valve holding body 1 and also protrude into the valve body 10 and thus a precise alignment enable the two high pressure bodies against each other.
- FIG. 2 shows a possible embodiment of the sealing film 35 shown.
- the sealing film 35 comprises in that shown here Embodiment in which in the valve body 10 in addition the inlet channel 20 and the bore 8 two centering pin bores 32 are formed, three ring-shaped areas, the inlet channel 20 and the two center pin holes 32 surrounded and the one another by connecting webs 36 are connected.
- figure 3 is an enlargement of FIG. 1 in the area of the contact surfaces, here the sealing film 35 for the sake of clarity is shown thickened. You can see that the sealing film 35 both the passage of the inlet channel 20 and the Passage of the centering pin holes 32 surrounds without in the to protrude into each passage.
- FIG 4 is another embodiment of an inventive Sealing film 35 shown.
- the one shown here Valve body 10 has only one centering pin bore 32 and next to it only the bore 8 and the inlet channel 20. Since here the inlet channel 20 and the centering pin bore 32 have the same diameter and each other with respect to the Opposite the center of the circular contact surface 110, can the sealing film 35 designed mirror-symmetrical be so that when assembling the fuel injector not be installed in the wrong way can.
- the contact surface 110 of the valve body 10 is one Recess 37 formed, in which the sealing film 35 is inserted is.
- the recess 37 is formed such that the sealing film 35 is not laterally on the contact surface 110 can slip.
- the recess 37 is not so deep that the sealing film 35 is completely immersed in it so that it is raised relative to the contact surface 110.
- the fuel injection valve comes into contact surface 101 of the valve holding body 1 on the sealing film 35 for contact and not on the contact surface 110.
- the sealing film 35 can be made from various materials his. For example, Steel which is a larger or may have a lower hardness than the steel from which the high pressure bodies are made. Furthermore, it can be provided, the sealing film 35 from a compared to Steel to produce soft metal, for example from copper or soft iron. Such a soft metal allows that the material flows when the clamping nut is tightened, so that minor bumps on the contact surfaces or dirt particles do not affect the tightness.
- the thickness of the Sealing film 35 can meet the corresponding requirements of Fuel injector or other high pressure fuel system be adjusted. It can only be a few ⁇ m or a few tenths of a millimeter, preferably the sealing film 35 has a thickness of 5 to 500 microns.
- the hardness of the material and the tightening torque of the nut is more or less strong flow of the sealing film 35 between the two High pressure bodies. Care must be taken here that the material of the sealing film 35 is not in the inlet channel 20 flows in and there to a narrowing of the flow cross section leads. In addition, it can also be provided that To produce sealing film 35 from a plastic, the Fuel is not dissolved and its softness ensures a good seal with low contact pressure.
- Sealing film 35 can also be provided, depending on the number the passage of channels or holes through the contact surfaces the high pressure body of the sealing film 35 other shapes to give. However, it must always be ensured that the Sealing film 35 the channels in the area of the passage in the form of an annular disk surrounds, so that there is always a good seal results.
- Example of a high pressure fuel system in the form of a Fuel injection valve can be a sealing film according to the invention also provided in other high-pressure fuel systems be in which the passage of a high-pressure fuel channel sealed by the contact surfaces of two high pressure bodies shall be. Examples of such high pressure fuel systems are high-pressure fuel pumps, line seals or pump-nozzle units and any connections of high pressure lines on high pressure bodies.
- the sealing film 35 is not a separate one To produce a part, but as a molding directly onto a Apply contact surface of a high pressure body. This can happen, for example, that a corresponding Layer electrolytically, galvanically or with a phototechnical Process is applied to the contact surface, so that the passages of the high pressure channels and the other holes are surrounded by a raised surface.
