Definitions
- the invention relates to a metallic sealing connection arrangement and a device of a fuel injection system with a metallic sealing connection arrangement. Specifically, the invention relates to the field of fuel injection systems of
- a rail assembly of a fuel injection system is known. This is used in particular for an internal combustion engine of a motor vehicle.
- the supply pipe has at its axial end, in which a pressure sensor connection is inserted, an inner contour which is configured conically complementary to an outer contour of an insert portion.
- this conical inner contour which has an outwardly widening inner cross-section, also form only by the axial pressing of the insert portion. This can ensure that the inner contour of the supply pipe exactly
- the rail assembly known from DE 10 2008 035 492 A1 and the connection provided in this case, which is formed by axial press-fitting, have the disadvantage that the resulting preloading force on the connection is largely indeterminate. Especially by the axial pressing in this case very large forces can occur, which requires a corresponding design of the connection partners. Since the cone angle for the conical inner contour is very small, the clamping forces that occur can very quickly become very large, so that a corresponding deformability of the supply pipe must be ensured.
- a screw connection is used.
- Ball / cone or cone / cone connection pairings with moving contact surfaces conceivable.
- a screw with a predetermined torque is possible, the interface seals by a flat contact. Due to the
- inventive metallic sealing connection arrangement with the features of claim 1 and the inventive device of a fuel injection system with the features of claim 10 have the advantage that an improved design and operation are possible.
- an improved sealing effect can be achieved.
- the power density can be increased with the same space, so that can be sealed against a higher pressure. Accordingly, the use of materials can be reduced to achieve predetermined requirements. This also allows one
- Fuel injection system possible. Specifically, use can be made in fuel injection systems for gasoline direct injection, wherein an air-fuel mixture is produced within cylinder combustion chambers of an engine designed as a gasoline engine. The fuel is injected for this purpose at high pressure into the combustion chambers.
- a fuel distributor can here as Pressure accumulator and serve to distribute the fuel to a plurality of fuel injection valves.
- a sensor can be used, which enables at least one pressure measurement and is preferably designed as a high-pressure sensor.
- a connection partner can be an internal pressure-carrying screw-in socket with a sealing function.
- the biasing force can not be maintained by a screw head, but via a sealing cone.
- connection partner is set next to the sealing point.
- Fuel storage is, and another connection partner, which is for example an attachment, possible.
- This metallic interface can be characterized in that a rotating bolt with thread and conical sealing surface, a threaded nut and spherical or toric sealing seat, a relative movement of the two connection partners (sealing partner) by the rotational movement when screwing the bolt and a plastic deformation of the one Connection partner as a result of
- a spherical or toric pin and a conical nut can be used in a possible modification.
- the attachment at the sealing point may be a sensor.
- plastic deformation can only take place at the pressure sensor nozzle by a suitable combination of materials.
- Interface can be achieved by a rotation angle controlled mounting method.
- An intended bolt internal pressure can be designed leader.
- a cone angle on the bolt can be between about 60 ° to about 120 °.
- a radius on the nut side be designed so that even with a maximum compression of this is not completely plastically deformed.
- the circumferential elevation is formed spherical and / or toric.
- a configuration corresponding to a partial shape of a torus, in particular a convex configuration is specified under a toric shape.
- Design is usually the partial form of a torus.
- a formation is possible in which the plastic deformation of the second connection partner is limited to the circumferential survey.
- an advantageous, circumferential seal can be achieved by a specific plastic contouring a sealing contour is set with an at least approximately predetermined size of the resulting sealing surface. Therefore, it is also advantageous that a plastic deformation between the first connection partner and the second connection partner only at the
- connection partner is designed so that at a maximum adjustable plastic deformation of the circumferential survey only a partial plastic deformation of the survey occurs.
- the screw connection between the first connection partner and the second connection partner can in this case advantageously be designed so that a sealing seat width at the deformed elevation between the first connection partner and the second connection partner over a rotation angle between the first
- connection partner and the second connection partner is adjustable.
- the degree of plastic deformation of the sealing contour of the second connection partner is also predetermined via the predetermined angle of rotation. It is also advantageous that due to the plastic deformation of the sealing contour of the second connection partner
- the first connection partner as a bolt having an axial bore, and the second connection partner as a nozzle, which has an axial through hole are configured.
- the axial bore or the axial through-bore can also be designed "axially” only with respect to the sealing region and not necessarily “axially” with respect to the entire component.
- the first connection partner as a nozzle, which has an axial through-hole, and the second connection partner as a bolt, which has an axial bore are configured. In this way, depending on the application, especially for the connection of a sensor, in particular a pressure sensor, specifically a plastic deformation can be achieved at only one of the connection partners.
- Sealing cone occurs. This can be explained in particular by locally high stresses at the edges of an intended chamfer. This is counteracted especially by the crowned or toric sealing contour on the seat, as a result, a more uniform increase in the voltage is achieved.
- a metallically sealing, modified in the contact area, modified ball / cone connection can be realized after assembly, wherein the sealing contour in the contact area is crowned or toric shaped, so that the "ball” modified in a spherical shape or as part of a tome Due to the mating material takes place during screwing a plastic deformation of the sealing contour, while the first connection partner, especially in his
- connection partner is specified.
- the extent of this tapered area allows the required sealing length and preload to be set very precisely. This is especially by means of a rotation angle controlled assembly process on the geometric relationship between the thread pitch and the angle of rotation.

- Connection partner 6 in the second connection partner 5 can be screwed.
- About the External thread 9 and the internal thread 10 is given a screw 11.
- connection partners 5, 6 can be connected to one another by screwing with respect to an axis 12 such that the connection partner 6 can be joined in a joining direction 13 into a recess 14 of the connection partner 5.
- a conical sealing surface 15 is formed.
- a cone angle 16 of the conical sealing surface 15 is selected here from a range of about 60 ° to about 120 °.

- the survey 18 runs around the axis 12.
- the circumferential elevation 18 is the conical sealing surface 15 of the
- connection partner 5 The sealing contour 19 of the connection partner 5 is designed so that when screwing the first connection partner 6 with the second connection partner 5, the circumferential elevation 18 of the second connection partner 5 is partially plastically deformed to a metallic seal between the conical sealing surface 15 of the first connection partner 6 and form in the bolted state at least partially deformed elevation 18 of the second connection partner 5. This process is described in more detail below with reference to FIG. 2.

- Angular position 20 just touches the survey 18 at a contact point 21 and a circumferential contact line 21. Upon further screwing, there is a plastic deformation of the elevation 18. In this way, for example, an end position can be assumed, which is illustrated by an interrupted line 22.
