Definitions

  • the invention relates to a decoupling element, which is used for decoupling a fuel injection valve from a cylinder head, and an arrangement with a fuel injection valve and such a decoupling element.
  • the invention relates to the field of fuel injection systems of internal combustion engines, fuel under high pressure being injected into associated combustion chambers of the internal combustion engine via fuel injection valves.
  • a compensation element for a fuel injector is known.
  • the compensating element is used for mounting a fuel injection valve in a cylinder head of an internal combustion engine.
  • the compensating element is ring-shaped and is arranged between a valve housing of the fuel injection valve and a wall of a receiving bore in the cylinder head.
  • the compensating element has legs which are supported on the fuel injection valve and the cylinder head. Here, a first leg rests on a shoulder of the cylinder head. A second leg rests on a shoulder of the valve housing. Undercuts and breakthroughs can be provided on the compensating element.
  • the compensating element can have segments that are punched out of the compensating element and bent radially inward. In this way, the compensating element both compensates for manufacturing tolerances of the individual components and also tolerances that are due to the heating of the fuel injector during operation, and thus prevents canting and incorrect positions.
  • a decoupling element for a fuel injection device is known.
  • the decoupling element creates a low-noise design.
  • the spring stiffness of the decoupling element is chosen to be so low and the decoupling element is placed in such a way that the decoupling resonance in the frequency range is below 2.5 kHz.
  • a possible misalignment of a fuel injection valve is compensated for by local weakening of an inner contact area of the decoupling element.
  • This local weakening of the radially inner contact area is achieved by radially extending slots which, starting from the inner diameter of the decoupling element, extend, for example, to the inner radius.
  • such slots or other openings reducing the rigidity can be provided in a number of three to twenty.
  • the decoupling element has a non-linear, progressive spring characteristic as a solid body joint, at least one contact collar having a spherical or spherical valve contact surface that extends up from a flat ring area, the flat ring area being based on a support base and the inside of the ring area one has a smaller inner diameter than the contact collar and the support base that is supported on the wall of the receiving bore.
  • a circumferential investment collar a plurality of investment collar sections distributed equally over the circumference can also be provided.
  • the ring area of the decoupling element can optionally also be supported with its inner edge on a snap ring resting on a valve shoulder.
  • the decoupling element according to the invention with the features of claim 1 and the arrangement according to the invention with the features of claim 3 have the advantage that an improved vibration damping is ensured over the service life.
  • the noise transmission of the fuel injector to the cylinder head can be reduced in a simple manner, with the smallest possible installation space and with low additional costs.
  • a specified target stiffness for example less than 50 kN / mm, can be maintained.
  • the problem of the circumferential tensions can be limited by a special segmentation, which means breaking up the rotational symmetry.
  • the decoupling stiffness then results from the sum of the stiffnesses of the individual segments distributed over the circumference. This corresponds to a parallel connection of spiral springs.
  • the segments acting as individual bending elements are held together only by a comparatively small, circumferential, closed ring of the cylinder-side support area of the base body.
  • a better elasticity of the segments is achieved, since they are designed to be comparatively large and can therefore be designed with a comparatively thick material thickness given a given target stiffness.
  • the mechanical circumferential stresses are concentrated on the cylinder-side support area of the base body, which does not contribute to the spring behavior and can therefore be designed in relation to the required circumferential forces.
  • Another advantage is that the function of the tolerance compensation element required for shear force compensation can be easily integrated into the shape of the segments (bending elements). Due to a spherical or similar design of the segments, the fuel injection valve on the decoupling element can tilt like on a ball joint and thus transverse forces and tolerance offsets between a center line of an installation hole on the cylinder head and a center line of a rail cup can be compensated.
  • the configuration according to the invention in which only the cylinder-side support area of the base body is at least partially designed in the form of a closed ring, has significant advantages.
  • This configuration is to be understood in such a way that the base body is segmented outside the cylinder-side support area into the segments distributed over the circumference.
  • this also includes the possibility that the segments distributed over the circumference also extend partially into the support region of the base body on the cylinder side. Then the support area of the base body on the cylinder side is only partially designed in the form of a closed ring.
  • the base body is pressurized when the fuel injector is supported between the valve-side support area and the cylinder-side support area.
  • the segments distributed over the circumference can advantageously act as bending segments. Comparatively large bending movements are possible in relation to a predetermined maximum stress on the material. Among other things, this enables advantageous tolerance compensation with regard to the positioning of the fuel injector.
  • the closed ring of the cylinder-side support area has bulges between the segments distributed over the circumference, which extend radially outwards.
  • the base body has recesses that are provided between the segments of the base body and that the recesses of the base body extend partially into the cylinder-side support area of the base body, so that the cylinder-side support area of the base body only partially in the form of a closed ring is designed.
  • the segments of the base body distributed over the circumference thus also extend somewhat into the support area. This further facilitates bending of the segments.
  • the component stresses occurring in the circumferential direction can also be concentrated in an advantageous manner on the closed ring.
  • the bulges provided between the segments distributed over the circumference ensure a sufficiently large material cross section in the region of the segments to absorb the forces acting in the circumferential direction. At the same time, the bulges do not affect the bending behavior of the segments. However, the contact area on the cylinder head can be enlarged by the bulges.
  • the bulges thus enable an improved configuration with further advantages. It is also advantageous here that the bulges of the closed ring, which partially bridge recesses that extend into the cylinder-side support area of the base body. In this embodiment, the bulges also extend somewhat into the areas of the cylinder-side support area, which adjoin the recesses on both sides in the circumferential direction. In this way, an advantageous introduction of force into the areas adjacent to the recesses and thus an advantageous non-positive connection over the circumference is achieved.
  • the closed ring of the cylinder-side support area is designed as an at least substantially flat cylinder-side support area for the cylinder head. This results in an advantageous support surface and reliable positioning on the cylinder head.
  • a securing element is configured at least on a segment of the valve-side support area, which in the assembled state interacts with the housing of the fuel injector.
  • a plurality of securing elements can be provided, each of which is prestressed in the radial direction against the housing of the fuel injector in order to form an anti-loss device. This also enables an advantageous assembly of the arrangement comprising the fuel injection valve and the decoupling element attached to it.
  • Fig. 1 shows an arrangement 1 according to the invention with a fuel injection valve 2 and a decoupling element 3 and a cylinder head 4 in a partial, schematic and spatial representation.
  • the arrangement 1 is used for a fuel injection system of internal combustion engines.
  • the arrangement 1 is particularly suitable for fuel injection systems for the direct injection of fuel into combustion chambers of the internal combustion engine.
  • the internal combustion engine can be designed as a mixture-compressing, spark-ignited internal combustion engine, it being possible to inject gasoline or other fuels suitable for such internal combustion engines as well as suitable mixtures of such fuels.
  • the decoupling element 3 is particularly suitable for such applications.
  • the arrangement 1 or the decoupling element 3 reduces the Noise transmission from fuel injector 2 to cylinder head 4 possible.
  • the fuel injection valve 2 can be configured as an electromagnetic high-pressure injection valve 2, which is used in gasoline engines with direct injection. Without a decoupling element, there is the problem that the fuel injection valve 2 makes a conspicuous and disruptive contribution to the overall noise of the engine.
  • a noise that can be described as valve ticking can arise, for example, from the rapid opening and closing of the fuel injector 2 when a valve needle is moved into the respective end stops with high dynamics. The impact of the valve needle on the end stops leads to short-term, very high contact forces, which can largely be transmitted to the cylinder head 4 as structure-borne noise and vibrations via a housing 5 of the fuel injector 2. This then leads to a strong noise development at the cylinder head 4, which is however significantly reduced by the decoupling element 3, which is located between the cylinder head 4 and the fuel injection valve 2.
  • the decoupling element 3 also has the requirement that it shows the required decoupling stiffness and the required strength with respect to a given small installation space, in particular at high system pressures over the service life.
  • the decoupling element 3 has a base body 6 with a cylinder-side support area 7 and a valve-side support area 8.
  • the cylinder-side support area 7 serves to support an upper side 9 of the cylinder head 4.
  • the valve-side support area 8 serves to support the fuel injector 2.
  • the decoupling element 3 surrounds the housing 5 of the fuel injector 2 circumferentially.
  • the top 9 of the cylinder head 4 is designed as a flat top 9 in this example.
  • the base body 6 of the decoupling element 3 is pressurized when the fuel injector 2 is supported between the valve-side support area 8 and the cylinder-side support area 7.
  • the base body 6 in this case has segments 15, 16, 17, 18 which are distributed over the handling and which are elastically bent when acted upon.
  • the segmentation of the valve-side support area 8 ensures optimum elasticity over the service life in relation to the predetermined material thickness. Stresses acting in the circumferential direction are considerably reduced by the segmentation in the valve-side support area 8.
  • the cylinder-side support area 7 of the base body 6 is at least partially in the form of a closed ring 20 designed.
  • only the cylinder-side support area 7 of the base body 6 is at least partially designed in the form of the closed ring 20.
  • the cylinder-side support area 7 of the base body 6 is only partially designed in the form of a closed ring 20. Because between the segments 15 to 18 recesses 21, 22, 23 are provided, which also extend somewhat into the cylinder-side support area 7. In this way, for example, a web 25 of the closed ring 20 remains in the recess 22, in which the cylinder-side support region 7, viewed in the circumferential direction, has a reduced radial extent of a flat support surface 26 ( Fig. 5 ) having.
  • the closed ring 20 of the cylinder-side support area 7 is designed as a flat cylinder-side support area 7 with a flat contact surface 26 for the cylinder head 4. Reliable positioning on the cylinder head 4 is thus possible. This also improves the vibration damping with a tolerance compensation for the fuel injector 2 that may be required at the same time.
  • the recesses 21, 22, 23 extending in the cylinder-side support region 7 are preferably maximally pronounced, so that the remaining ring thickness on the web 25 is reduced to a possible minimum.
  • Fig. 2 shows the in Fig. 1 Arrangement 1 shown and the cylinder head 4.
  • an outer edge 27 of the closed ring 20 is bent upwards viewed from the top 9 of the cylinder head 4.
  • the stability of the closed ring 20, in particular on the web 25, can be improved in this way, especially when space is limited.
  • Fig. 3 shows the in Fig. 1 Arrangement 1 shown and the cylinder head 4.
  • the closed ring 20 of the cylinder-side support area 7 has bulges 28 between the segments 15 to 18 distributed over the circumference, only the bulge 28 being marked for simplification of the illustration.
  • the bulge 28 extends radially outwards.
  • the bulge 28 in this exemplary embodiment increases the bearing surface 26 of the cylinder-side bearing region 7.
  • the bulge 28 in this case bridges the recess 22 which extends partially into the bearing region 7 on the cylinder side.
  • the recess for absorbing the circumferential tensile forces becomes significant cross-sectional area increased in particular in the region of the web 25.
  • the bulge 28 also extends into areas (zones) 29, 30 of the cylinder-side support area 7, which adjoin the recess 22 in the circumferential direction.
  • the zones 29, 30 thus enable an advantageous frictional connection in the closed ring 20.
  • Fig. 4 shows the decoupling element 3 of the in Fig. 1 Arrangement 1 shown in a partial, schematic and spatial representation to illustrate the operation.
  • the upwardly curved segments 16, 17 are designed in the form of curved tabs which provide the fuel injector 2 with a support or support on the line 31 drawn in for illustration. Via this line (support line) 31, the load is transferred to the decoupling element 3 due to the hold-down and the pressure forces on the fuel injector. The segments 16 to 18 bend due to the load. The total stiffness of the decoupling then results from the sum of the individual bending stiffnesses. This corresponds to a parallel connection of individual spiral springs.
  • the function of tolerance compensation for compensating lateral forces and / or a tolerance-related offset is also integrated into the decoupling.
  • the segments 15 to 18 can be designed in a suitable shape, number and thickness by shape optimization in such a way that the desired rigidity is achieved with the required strength.

  • the securing element 32 can be expanded outward in the radial direction when it is applied to the housing 5.
  • clawing into the housing 5, in particular a magnetic pot of the housing 5 can be achieved by a special shaping of the securing element 32. This forms a protection against loss.
  • Fig. 6 shows an arrangement 1 not according to the invention and the cylinder head 4.
  • the segment 18 is designed as an inwardly open segment 18.

  • a spacer element 33 is configured on the segment 18 of the valve-side support area 8, which faces the cylinder-side support area of the base body 6. When the valve-side support area 8 is pressed against the cylinder-side support area 7, the spacer element 33 strikes the cylinder-side support area 7 after a certain movement path.
