Definitions
- the invention relates to a sealing device according to the type of the main claim.
- a fuel injection system which has a compensating element which consists of a support body which has a spherical support surface.
- a fuel injector is supported via this compensating element in a receiving bore in a cylinder head.
- In the annular gap between the receiving bore and the fuel injection valve there is a sealing ring in a groove of the fuel injection valve, which seals the annular gap from the combustion chamber. Since the fuel injection valve rests on the spherically shaped spherical cap surface with a support surface, the fuel injection valve can be mounted up to a certain angular deviation from the axis of the receiving bore and can be pressed firmly into the receiving bore by suitable means, for example a clamping claw.
- a disadvantage of the fuel injection system known from DE 197 35 665 AI is that the geometry of the fuel injection valve must be changed to adapt to changed installation geometries in the cylinder head.
- the seal acting in the radial direction requires a high degree of positional accuracy of the receiving bore and the outer geometry of the fuel injector relative to one another.
- the sealing device according to the invention with the characterizing feature of the main claim has the advantage that an adaptation to different geometries is simple and the interface of the fuel injector to the adjacent component remains unchanged.
- the sealing surface formed on the sealing sleeve in the axial direction enables simple machining of the corresponding surface of the cylinder head.
- the possibility of influencing the surface pressure on the axial sealing surface is also advantageous, as a result of which component tolerances have a smaller effect.
- the elastic sealing sleeve is also suitable for compensating position and angular tolerances.
- the intermediate sleeve for generating the axial force on the sealing sleeve is also advantageous, as a result of which the external geometry of the fuel injector can be changed within a wide range using an inexpensive component.
- Fig. 1 shows a schematic partial section through a first embodiment of an inventive
- Fig. 2 shows a schematic section through a second embodiment of a sealing device according to the invention.
- FIG. 1 A first embodiment is shown in FIG. 1.
- the fuel injector 1 is sealed with a radially sealing sealing element 3 against a sealing sleeve 4.
- the sealing sleeve 4 is acted upon by an intermediate sleeve 13 in the axial direction with a force which leads to the formation of a sealing surface pressure between the sealing sleeve 4 and the cylinder head 2.
- the cylinder head 2 For receiving the fuel injection valve 1, the cylinder head 2 has a receiving opening 6, which has a shoulder in the direction of the combustion chamber of the internal combustion engine, which shoulder is designed as a contact surface 7 for the sealing sleeve 4.
- the fuel injection valve 1 has at its downstream end a cylindrical nozzle body 8, into which a circumferential groove for receiving the sealing element 3 is made.
- the sealing sleeve 4 has a hollow cylindrical section 9, the inner radial extent of which corresponds to the radial extent of the sealing element 3, so that the sealing sleeve 4 produces a sealing press connection with the sealing element 3.
- On the upstream side of the sealing sleeve 4 is one arranged collar-shaped extension 10, the outer radial extension of which is greater than the inner radial extension of the shoulder in the receiving opening 6 of the cylinder head 2.
- the collar-shaped extension 10 has a curvature 11 formed in the upstream direction. Towards the outer circumference, the arch 11 merges into an oppositely directed second arch, on the downstream side of which an axial sealing surface 12 is arranged. The axial sealing surface 12 forms a sealing seat with the contact surface 7 of the receiving opening 6.
- the sealing sleeve 4 is pressed onto the contact surface 7 by an intermediate sleeve 13, which can also be pushed onto the nozzle body 8 of the fuel injection valve 1.
- a pressing surface 14 is formed at the downstream end of the intermediate sleeve 13. It arises by folding the downstream end of the intermediate sleeve 13 between the outer radial extent of the
- Sealing element 3 corresponds.
- the intermediate sleeve 13 is supported on a circumferential oblique shoulder 15 of the fuel injector 1.
- the intermediate sleeve 13 is via a housing part 16 of the
- Fuel injector 1 pushed.
- the axial and radial expansion of the circumferential curvature 11 of the sealing sleeve 4 are so large that the curvature 11 is supported on the pressing surface 14 formed by the intermediate sleeve 13.
- the curvature 11 of the sealing sleeve 4 is shaped such that the axial sealing surface 12 is the only contact surface of the sealing sleeve 4 with the contact surface 7 of the receiving opening 6.
- the intermediate sleeve 13 transmits at least part of the axial force, which is exerted on the fuel injection valve 1 by a fastening means, not shown, to the curvature 11 of the sealing sleeve 4 and thus to the axial sealing surface 12 Intermediate sleeve 13 and the cylinder head 2 clamped sealing sleeve 4 elastically deformed.
- the tension thus built up in the sealing sleeve 4 makes it possible to compensate for component tolerances without reducing the sealing effect.
- a clamping claw can be used as a fastening element, for example, which presses the fuel injection valve 1 against the cylinder head 2 with a flange 5 provided for this purpose.
- the axial distance between the downstream side of the flange 5 and the sealing surface of the sealing sleeve 4 in the unloaded state is greater than the distance between the corresponding contact surface, so that a tension is always built up in the sealing sleeve 4 when the fuel injector 1 is installed in the cylinder head 2, which generates the sealing surface pressure of the sealing surface 12 on the contact surface 7.
- the intermediate sleeve 13 is first pushed onto the fuel injection valve 1. Subsequently, the sealing sleeve 4 is pushed onto the fuel injector 1, whereby the intermediate sleeve 13 is held on the fuel injector 1.
- the forces designed to build up a sufficient sealing effect between the sealing element 3 and the sealing sleeve 4 are large enough to be able to use the sealing sleeve 4 as an assembly aid when inserting the fuel injection valve 1.
- FIG. 2 A second exemplary embodiment with a modified form of the intermediate sleeve 13 is shown in FIG. 2.
- the intermediate sleeve 13 is shortened and does not include the housing part 16 of the fuel injector 1, but is supported on its downstream side.
- the shortened design of the intermediate sleeve 13 enables improved dissipation of the heat introduced.
- the direct connection of the sealing sleeve 4 to the nozzle body 8 and the cylinder head 2 ensures good heat dissipation into the cylinder head 2 during operation of the internal combustion engine.
- the sealing sleeve 4 is preferably made of spring-elastic, low-alloy stainless steel, spring-hard CuSn6 or CuBe2. With the choice of the material used, an adaptation of the sealing sleeve 4 with regard to the mechanical properties as well as the corrosion resistance and the heat dissipation to the corresponding application can be achieved.
