Description

Valve for metering a fluid
Technical Field
The invention relates to a valve for metering a fluid, in particular a fuel injection valve for an internal combustion engine. The invention relates in particular to the field of injectors for fuel injection systems of motor vehicles, in which direct fuel injection is preferably carried out in the combustion chamber of an internal combustion engine.
Background
DE 102005020380 a1 discloses a fuel injection system comprising a fuel injection valve, a receiving bore in a cylinder head for the fuel injection valve, and a fuel distribution line having an attachment stub into which the fuel injection valve is inserted in a partially overlapping manner. The connecting body is arranged in the receiving bore in such a way that the fuel injection valve is held in the connecting body in such a way that all surfaces or walls of the fuel injection valve and the connecting body, which do not extend axially parallel to the injection valve, are inserted without contact relative to the receiving bore of the cylinder head. In the known configuration, the connecting body is for this purpose mounted directly on the attachment stub of the fuel distribution line.
Disclosure of Invention
The invention relates to a valve for metering a fluid, in particular a fuel injection valve for an internal combustion engine, having a valve housing, wherein a tolerance compensation element is provided, which is arranged on the valve housing and surrounds the valve housing in an annular manner with respect to a longitudinal axis of the valve housing, wherein a securing element is provided, which at least partially surrounds the valve housing and is inserted at least partially into an annular groove formed on the valve housing in order to secure (fix) the tolerance compensation element on the valve housing, and wherein at least one projection extending radially outward with respect to the longitudinal axis of the valve housing is formed on the securing element.
The valve according to the invention has the advantages that: advantageous configurations and operating modes can be achieved. In particular, the valve can be advantageously arranged in the receiving bore.
The invention also provides an advantageous development of the valve.
The tolerance compensation element can be configured in an advantageous manner annularly, wherein a suitable contour can be selected depending on the respective application. The tolerance compensation element can in particular compensate for radial tolerances. Tolerance compensation can be achieved, for example, with respect to a receiving bore for the valve. Such a receiving opening can be formed, for example, on the cylinder head.
In principle, it is conceivable for the securing element to bear circumferentially against the valve housing as a securing ring and to be designed in the form of a simple ring. With such a securing element, it is likewise possible to secure the tolerance compensation element, in which case the tolerance compensation element is prevented from falling out during transport, during installation, during possible disassembly and the like. However, this may require a securing element with a large wire diameter in order to prevent the tolerance compensation element from falling off, based on the corresponding tolerance compensation element. This is disadvantageous in terms of installation space and may not be possible for installation space reasons.
The safety element mentioned makes it possible to achieve a geometry which not only enables a reliable safety of the tolerance compensation element on the valve, but also enables an advantageous geometry of the safety element, in particular a small wire diameter. This also makes it possible to use special tolerance compensation elements which, for example, make it possible to compensate for radial tolerances of the inner diameter of the receiving bore or of the outer diameter of the valve housing. In particular, this enables the tolerance compensation element to be configured from plastic. The securing element can be made of steel or based on steel, for example. In particular, the securing element is formed from a wire, in particular a steel wire.
According to the invention, a plurality of projections extending radially outward with respect to the longitudinal axis of the valve housing are formed on the securing element. This has the advantage that: the tolerance compensation element can advantageously be secured on the periphery. In particular, the embodiment according to this aspect provides that the projections formed on the securing element are distributed at least approximately uniformly over the circumference with respect to the longitudinal axis, which is particularly advantageous.
According to the invention, the securing element is inserted at least partially into an annular groove formed on the valve housing between two adjacent projections. This has the advantage that: an advantageous fixing between the projections can be achieved. In this case, for example, the wire diameter can be selected to be small, since the fixation is essentially achieved by the geometry of the securing element in the case of a projection, not by the wire thickness. The wire thickness can then be selected such that sufficient stability is ensured for possible bending. The possible small wire diameters in this way also make it possible to correspondingly form the annular groove small in a corresponding manner. This allows on the one hand a greater freedom in positioning the annular groove on the valve housing. On the other hand, a small space requirement for the realization of the annular groove in the valve housing is obtained, which in turn has an advantageous effect on the installation space requirement.
The projection on the securing element thus enables a large tolerance gap to be spanned while the wire thickness is thin. This has the advantageous effect of complying with predefined installation space restrictions.
According to the invention, the securing element is interrupted at one point. This has the advantage that: the securing element can advantageously be mounted on the valve housing. This embodiment makes it possible in particular to achieve a simple assembly if the securing element is to be applied to the valve housing with a pretensioning force in the assembled state, if the securing element engages with the valve housing with a pretensioning force. The securing element, which is preferably configured as a slotted securing ring, can advantageously be produced from a stainless steel wire coil. Such a securing element can be expanded by the flange of the valve housing and can find its final position in a groove provided on the valve housing.
One possible configuration is to realize, for example, four or five projections on the securing element, which are distributed uniformly over the circumference. These projections block the tolerance compensation element so that it cannot fall out over the safety ring. Dropping over the safety ring can cause the tolerance compensation element to fall off, thereby preventing this in the manner described above.
The specific embodiment of the projection can be predefined on the basis of the respective application. The surrounding outer diameter of the securing element, in particular of the securing ring, is particularly important for the securing function. The inner diameter and the cross-sectional profile of the securing element, in particular the wire diameter, are particularly important for a predetermined pressing force and/or the required removal force. The geometric design of the fuse element can thus be advantageously carried out on the basis of the conditions which are important in the respective application case.
In an advantageous manner, the securing element, in particular the securing ring, is interrupted at a point of the circumference, so that the securing ring acts as a C-spring during installation. In this case, it is provided according to the invention that the securing element is interrupted at one point by a gap and that the gap width of the gap is smaller than the minimum extension of the cross-sectional contour of the securing element. This enables an advantageous storage of a plurality of fuse elements for installation. In particular, the width of the interruption, in particular the width of the gap, can be selected to be smaller than the wire thickness, so that the securing elements can be handled as individual parts and do not catch on one another during storage. This advantage is achieved in particular when the securing element is formed from a wire and the gap width of the gap is smaller than the minimum wire thickness of the wire.
According to the invention, the projection is formed by a bend of the securing element. This makes it possible in particular to realize the fuse element on the basis of a bent wire. Such a wire, which may be made of stainless steel in particular, may be bent in a predetermined shape with one or more projections. This enables manufacturing at a low unit cost.
The realization of the securing element with one or more projections also has the advantage: a greater degree of freedom is obtained when the compensation element is predefined. In particular, the compensation element can be made of or at least partially based on plastic. The projection adapted in this way can also prevent the compensation element from falling off beyond the securing ring in the case of more elastic plastics and thus in the case of a better deformable compensation element.
Drawings
Preferred embodiments of the present invention are explained in more detail in the following description with reference to the figures, in which corresponding elements are provided with corresponding reference numerals. Shown here are:
fig. 1 shows a valve in a schematic sectional illustration according to an exemplary embodiment of the invention; and
fig. 2 shows a schematic perspective view of the securing element of the valve shown in fig. 1.
Detailed Description
Fig. 1 shows a valve 1 in a schematic sectional illustration and a cylinder head 2 in a partially schematic illustration according to an exemplary embodiment. The illustrated assembly 3 with the valve 1 and the cylinder head 2 shows a preferred application in which the valve 1 is used as a fuel injection valve for an internal combustion engine. The cylinder head 2 delimits a combustion chamber 4 of the internal combustion engine, into which the valve 1 injects fuel directly during operation. In this case, a correspondingly arranged further valve for the direct injection of fuel into the combustion chamber of the associated internal combustion engine is preferably provided. In this case, liquid or gaseous fuels can be used as fuel. However, the valve 1 is also suitable for other applications.
The valve 1 has a housing 5, which can be embodied in several parts. In particular, the housing 5 can have a base body 6, an attachment socket 7 connected to the base body 6 and a nozzle body 8 connected to the base body 6. The interfaces between the individual housing parts 6 to 8 are suitably embodied here, but are not shown in detail in order to simplify the illustration.
An annular groove 9 is formed on the valve housing (housing) 5. Furthermore, a tolerance compensation element 10 and a securing element 11 are provided. The tolerance compensation element 10 is configured on the basis of the desired arrangement and orientation of the valve 1 in a cylindrical bore 12 of the cylinder head 2, which serves as a receiving bore 12. The securing element 11 serves to fix or secure the tolerance compensation element 10 to the valve housing 5. The securing element 11 is in this case configured as a securing ring 11.
In the mounted state, a portion 13 of the receiving bore 12 is sealed off from the combustion chamber 4 by an annular sealing element 14 arranged on the nozzle body 8. Thereby preventing gas from entering the portion 13 of the receiving bore 12 from the combustion chamber 4. The tolerance compensation element 10 is thus protected against the thermal and chemical aspects associated therewith. This enables the tolerance compensation element 10 to be configured on the basis of at least one plastic. In this case, by means of this particular design of the securing element 11, it is also possible to use elastically deformable plastics.
In particular, securing by the securing element 11 is required when the valve 1 is inserted into the receiving bore 12 or when the valve 1 is removed from the receiving bore 12. In particular, the tolerance compensation element 10 is thereby prevented from falling out of the valve housing 5, for example during disassembly, and being completely or partially left in the receiving bore 12. For this purpose, the extension of the securing element 11 in the exemplary illustrated radial direction 15 with respect to the longitudinal axis 16 is particularly advantageous. However, if there is no installation space required for this purpose in the receiving bore 12 or on the valve housing 5, this may not be possible by increasing the diameter d of the cross-sectional contour 17 of the securing element 11. Furthermore, a large diameter d may also be disadvantageous for other reasons.
In order to make it possible for the securing element 11 to extend in the radial direction 15, projections 21 to 24 are provided on the securing element 11 in this exemplary embodiment. This embodiment of the securing element 11 is also explained in more detail below with reference to fig. 2.
Fig. 2 shows a schematic perspective view of the securing element 11 of the valve 1 shown in fig. 1. The securing element 11 is preferably mounted on the valve 1 in such a way that it is oriented on a plane 25,26, which is shown here by two dashed lines 25, 26. An angle 27 of 90 ° is provided between the dashed lines 25, 26. The projections 21,23 are shaped, viewed in the planes 25,26, to be bent symmetrically about the line 25. The projections 22,24 are correspondingly also symmetrically curved about the line 26. The securing element 11 has sections 29 to 32 in the circumferential direction 28 about the longitudinal axis 16. The section 31 is divided into two parts 33, 34. The division of the portion 31 is brought about by the interruption of the portion 31 at the point 35 by means of the slit 36. The gap width 37 of the gap 36 is smaller than the diameter d of the cross-sectional contour 17 of the securing element 11.
However, the securing element 11 does not necessarily have to be configured with a circular cross-sectional contour 17. If the securing element 11 is formed from a wire 38, the gap width 37 of the gap 36 is predefined to be smaller than the minimum wire thickness dmin. This makes it possible to handle the securing element 11 as a separate part without hooking each other.
If the securing element 11 is configured as a wire or the like, the projections 21,24 can advantageously pass through the curved configuration of such a wire 38. In particular, the projections 21 to 24 can be formed by a bend 21 to 24 of the securing element 11 or of the wire 38 along its periphery. The inner diameter D of the securing element 11 can be predetermined in such a way that a pretensioning is achieved when the securing element 11 is engaged on the valve housing 5. In addition, the diameter d can be predetermined in such a way that the securing element 11 is completely or partially inserted into the annular groove 9 on the valve housing 5. The securing element 11 is then inserted completely or partially between the sections 29 to 32 or between the projections 21 to 24 into the annular groove 9 formed on the valve housing 5.
In this exemplary embodiment, the projections 21 to 24 are each spaced apart from one another in pairs by 90 ° with respect to the circumferential direction 28, as is shown here by way of example by an angle 27 of 90 °. However, other configurations are also contemplated.
In a modified embodiment, an angle 27 other than 90 ° can also be provided. Other numbers of projections 21 to 24 may also be provided. However, a configuration is advantageous in which a predetermined number of projections 21 to 24 are formed on the securing element 11 at least approximately uniformly distributed in the circumferential direction.
The tolerance compensating element 10 can be configured with a suitable inner diameter 40, a suitable outer diameter 41 and a suitable cross-sectional profile 42 depending on the respective application. In this case, different possibilities are conceivable, such as the tolerance compensation element 10 interacting with the valve housing 5 on the one hand and the receiving bore 12 on the other hand. The illustrated contact of the tolerance compensation element 10 between the valve housing 5 and the securing element 11 on the one hand and on the receiving bore 12 on the other hand represents an exemplary application. Due to this advantageous configuration of the securing element 11, it is not absolutely necessary, for example, for the tolerance compensation element 10 to bear with its inner diameter 40 against the valve housing 5. However, configurations are conceivable in which the tolerance compensation element 10 rests with its inner diameter 40 on the valve housing 5. If the tolerance compensation element 10 is correspondingly embodied in a deformable manner and/or the tolerances to be compensated are sufficiently small, the radial compensation can be achieved, for example, by elastic deformation of the tolerance compensation element 10.
The invention is not limited to the illustrated embodiments.
