- this flange 14 is connected to the high-pressure fuel pump 10 as a one-piece flange and as made separate component, and is welded to the housing 12 during the pump assembly. That is, this flange 14 is normally connected to the high-pressure fuel pump 10 by means of a weld material fit.
- the weld allows no subsequent reorientation of the flange 14 and the high-pressure fuel pump 10, which, for example, in an offer phase can lead to increased problems with time-critical sample structures.
- a subsequent reorientation of the high-pressure fuel pump 10 may also be useful in Baumraumuntersuchungen if necessary.
- the flexibility and thus the orientation options are limited so far only on the specified high-pressure fuel pump 10th
- both flange 26 must be supported on the two parallel groove surfaces top and bottom. This causes considerable stresses in the component, which can lead to deformations, for example, of highly accurate guide elements. Thus, this method is not good for the application or only partially suitable.
- the two flange portions 26 of the flange 14 can therefore be attached either at the pump assembly to the housing 12 of the high-pressure fuel pump 10, for example by welding and delivered in this way to the customer, or alternatively it is also possible to send them as individual parts to the customer, so this can put the flange 14 directly on the engine block on the housing 12 of the high-pressure fuel pump 10.
- the handling of the high-pressure fuel pump 10, for example, during assembly or transport, can therefore be done without flange 14. Thus, the handling is due to the not changed
- the flange in Fig. 1 accordingly has two flange portions 26, which are separated from each other, and which are connected by an overlap or a positive engagement in each case two Flanschharms Suiteen 28 to form an overall flange 14.

- the first flange plane 40 and the second flange plane 41 are arranged parallel to one another but at a distance, and are also not located in the flange main plane 39, which is defined by the fastening region 38.
- both flange portions 26, which form the entire flange 14, are formed identical to one another. Therefore, when a flange member 26 in the embodiment shown in FIG. 2 is brought into contact with itself, the protruding connecting members 50 slide over the planar connecting members 46 of the other flange member and the flat connecting members 46 of the one flange member 26 slide under the protruding connecting members 50 This results in a positive engagement of the flat connecting elements 46 and the protruding connecting elements 50 and thus a secure connection of the two separately executed flange 26.
- the particularly secure connection of the two flange 26 results from the fact that each two areas or elements in each flange connection area 28 are available for the positive connection.
- the two flange portions 26 of the flange 14 are made identical, thus facilitating the assembly, since there is no likelihood of confusion, and to keep the unit cost as low as possible, since at higher quantities a lower part price.

- FIG. 5 shows a sectional view through the line AA from FIG. 4 of the two flange connection regions 28 of a connection embodiment according to FIG. 2.
- FIG. 6 shows a perspective view of a third embodiment of one of the two flange parts 26, the two flange connection regions also being shown here 28 are executed differently.
- a channel elevation 52 is provided, wherein viewed from the Flanschsch distrierachse AH along the longitudinal axis AL before the channel elevation 52, a recess 56 is arranged.
- a connecting plate 48 is provided, which is here designed as a bridge element 58 and to a disposed in the first flange 40 bridge portion 60A and a portion disposed outside the first flange 40 bridge portion 60B has. If two flange parts 26 formed in accordance with FIG. 6 are connected to one another, the bridge element 48 can simply be levered into the recess 56 so that a partial region 62 of the connecting strap 48 formed as a bridge element 58 is received by the recess 56. In order to allow a stable connection of two flange parts 26, the channel bump 52 is formed so as to extend parallel to the flange bisecting axis AH over the entire flange connecting portion 28.
- Fig. 7 shows a perspective view of a fourth embodiment of the flange 26, wherein in a Flanschharms Scheme 28 again a channel elevation 52 is provided, and in the other Flanschharms Complex 28 the
- Connecting straps 48 wherein a connecting strap 48 in the first flange plane 40 and the other two connecting straps 48 are arranged outside the first flange plane 40.
- a recess 56 is provided along the longitudinal axis AL seen from the Flanschschierachse AH from behind the channel elevation 52.
- the flat connection tab 48 in the first flange plane 40 is formed longer along the longitudinal axis AL than the other protruding connecting tabs 48, and can Therefore, after it has intervened in the channel elevation 52, be mechanically bent into the recess 56 so as to realize a secure connection of the two flange portions 26.
- the flange parts 26 are formed from a mechanically deformable sheet material 64 at least in the flange connection regions 28.
- the flat connecting strap 48 is formed from this mechanically deformable sheet material 64.
- FIG. 8 shows a sectional view through the region in which the two flange parts 26 are connected to one another, the two flange parts 26 being designed in accordance with FIG. 6. It can be seen that the connecting plate 48 of a Flanschver ⁇ binding region 28 just levered into the recess 56 of the other Flanschharms Symposiumes 28th 9 shows a sectional view through the region in which the two flange parts 26 are connected to each other, according to the embodiment shown in Fig. 7, wherein the central connecting plate 48 is bent into the recess 56.
- one or more portions 62 of the flange 14 may be after the positive-fit joining of the two
- Flange members 26 are formed to prevent disengagement of the two flange members 26.
- this step can also be omitted by geometrically shaping the components in such a way that they are already inserted into one another in a form-fitting manner and already join, namely by means of joining by levering, which is shown in FIG. 8.
