Definitions
- the invention relates to a high-pressure pump according to the preamble of claim 1, and a flange according to the independent claims.
- the problem underlying the invention is solved by a high-pressure pump according to claim 1.
- Advantageous developments are specified in subclaims.
- the invention has the advantage that a flange on a housing of a high-pressure fuel pump ("high-pressure pump") by means of caulking form fit or non-positively by means of press-fitting instead of each cohesively.
- a welded connection between the flange and the housing is not required.
- the elimination of welding eliminates the introduction of thermal energy and a resulting structural change in a material of the welding partners. As a result, unwanted deformations of the flange or of the housing as a result of microstructural changes are simultaneously reduced.
- a sequence of assembly steps in the manufacture of the high-pressure pump can be made more flexible, which can result in manufacturing simplifications and cost savings.
- inventive caulking or press-fitting of flange on the housing of the high pressure pump a dirt entry is avoided, as is possible, for example, in a welding operation as a result of welding spatter and smoke.
- the flange can be made inexpensively and with relatively little mass of another material instead of stainless steel.
- the at least two-part flange according to the invention with respect to a one-piece design has the advantage that in the production of the flange parts by means of punching a comparatively low material waste can be achieved.
- each of the flange parts has only one, for example, a semicircular recess.
- an optimal arrangement of a flange contour on a strip of material during punching is possible.
- no additional connecting elements for the arrangement of the flange on the housing of the high pressure pump are required.
- Such fasteners would be pins, for example.
- a required positioning accuracy between the flange and the housing of the high-pressure pump is comparatively low, since no holes for pressing in said pins must be aligned. Likewise, additional holes can be omitted on the housing for pressing in the pins.
- One Another advantage is that the flange can be applied before caulking with the housing with clearance, which may be tolerances compensated component tolerances.
- the invention relates to a high-pressure pump, in particular plug-in pump, for a fuel system for an internal combustion engine, wherein the high-pressure pump comprises a housing and a flange arranged rigidly on the housing.
- the flange has at least two parts, the high-pressure pump having a groove-like receiving region ("groove"), in which a radially inward region of the flange parts is accommodated.
- the flange parts are held on the housing by a caulking connection and / or a press connection.
- a welded joint for the arrangement of the flange on the housing is unnecessary, which eliminates the specific disadvantages.
- the flange parts have recesses which are arranged on the flange parts in such a way that the recesses of the flange parts are partially covered by the groove in their installed position, wherein a material of the housing is caulked in the recesses. This creates space for the material changes made by the caulking in a simple and cost-effective way.
- the recesses are designed as circular holes. Circular holes can be produced in a particularly simple and cost-effective manner during the course of a stamping process, as a result of which the production of the high-pressure pump can be made cheaper.
- the radially inward regions of the flange parts have sections which have a greater material thickness and / or a different type of embossing than regions lying laterally thereof.
- the flange parts are pressed into the groove.
- the press-fit forces can be greatly reduced, since the contact surface between the flange on the one hand and the housing on the other hand reduced or even minimized and also the flange parts in the region of said sections are much more elastic.
- the housing of the high-pressure pump is generally designed for sufficient corrosion protection for contact with ethanol-containing fuel made of stainless steel. Because a connection between the flange and the housing according to the invention does not require a welded connection, therefore, the flange can be advantageously made of a different material to the housing.
- the housing and the flange are made of different stainless steels.
- a cheaper stainless steel can be used for the flange, whereby material costs can be reduced accordingly. It is not absolutely necessary that the stainless steel has the property of weldability.
- the flange is provided that it is made of aluminum or an aluminum compound or steel.
- the stainless steel for the material of the flange part are described, whereby the production of the high pressure pump can be simplified and costs can be reduced. This is possible in particular because the flange is not connected to the housing by means of a welded connection.
- the flange part is produced by stamping and / or embossing.
- Previously known embodiments of flanges are generally made in one piece and therefore have at their center a circular hole which serves to connect the flange to the housing of the high-pressure pump.
- each flange part has only one example semi-circular recess on.
- FIGS. 1A and 1B show a designed as a plug-pump high-pressure pump 10 for a fuel system for a (not shown) internal combustion engine in a first and second view.

- An in the Figures 1A and 1B Left and right areas, the flange portions 16a and 16b on edge portions 22 which are lifted by means of a stamping operation of other areas of the flange 16a and 16b, and thus allow a three-dimensional geometry of the flange 16a and 16b.
- the flange portions 16a and 16b are stiffened by the edge portions 22, resulting in greater strength.
- each of the flange parts 16a and 16b has a circular attachment hole 24.
- the fastening holes 24 By means of the fastening holes 24, the flange parts 16a and 16b, and thus the high-pressure pump 10, can be screwed to the mounting structure 12.
- the fastening holes 24 By means of the fastening holes 24, the flange parts 16a and 16b, and thus the high-pressure pump 10, can be screwed to the mounting structure 12.
- screws are in the Figure 1A and the FIG. 1B but not shown.
- FIG. 1B shows the arrangement of the high-pressure pump 10 after the Figure 1A in a partial sectional view tilted by 90 °.
- the groove-like receiving region 18 is arranged radially circumferentially on a radially outer region of the housing 14.
- the housing 14 of the high-pressure pump 10 is shown only in a region of the flange parts 16a and 16b.
- the embodiment of the high-pressure pump 10 corresponds to the Figures 1A and 1B
- conventional embodiments of high-pressure fuel pumps which are designed as piston pumps, in particular as plug-in pumps.
- An assembly of the flange parts 16a and 16b on the housing 14 takes place for example by means of the following steps: In a first step, the two flange parts 16a and 16b are applied to the groove-like receiving area 18 in a defined position. In a second step, a material of the housing 14 is caulked by Kreisverstemmitch in the space provided for recesses 20. Preferably, at least two recesses 20 per flange 16a and 16b used to prevent a radial displacement and / or a tangential rotation of the flange portions 16a and 16b relative to the housing 14. In this case, the recesses 20 only a partial overlap with the groove-like receiving area 18.
- the groove-like receiving portion 18 can be made with a comparatively small radial depth, whereby a required for the production of the housing 14 machining is facilitated.
- the Figures 1A and 1B describe a substantially positive connection between the housing 14 and the flange 16a and 16b.
- FIGS. 2A and 2B show one to the Figures 1A and 1B Alternative embodiment of the flange parts 16a and 16b and the high-pressure pump 10.
- the flange part 16b is shown in a perspective view.
- the flange portion 16b has in a radially inward region present three sections 26, which have a greater material thickness or a different type of embossing as lying laterally of their areas.
- the two flange parts 16a and 16b are also in the FIGS. 2A and 2B similarly executed.
- the two flange portions 16a and 16b in the radially encircling groove-like receiving portion 18 is pressed ("press connection"). Accordingly, in each case at least three radially inward areas, by means of which the flange parts 16a and 16b are held on the housing 14.
- a welded connection for fastening the flange parts 16a and 16b to the housing 14 is in the FIGS. 2A and 2B and also in the Figures 1A and 1B not mandatory.
- sections 26, deviating from the example of FIGS. 2A and 2B in almost any number, arrangement and shape can be arranged on the flange 16a and 16b.
- elements comparable to the sections 26 in a region of the groove-like receiving region 18 of the housing 14 instead of the flange parts 16a and 16b. This is in the FIGS. 2A and 2B but not shown.
- the housing 14 of the high-pressure pump 10 is made of a comparatively high-grade stainless steel, which makes it possible for the high-pressure pump 10 to be operated without corrosion with an ethanol-containing fuel.
- the two flange parts 16a and 16b are made of a different and relatively inexpensive stainless steel.
- the flange 16a and 16b are also produced by punching and / or embossing.
