Furthermore, the device comprises a plurality of fluid-tight passages, which are completely formed extending through said high-pressure fuel accumulator and extend substantially perpendicular to the longitudinal axis, and a plurality of screws, which are to be inserted through the respective plurality of fluid-tight passages.
  • the fastening elements may be attached to the cylinder head, whereby the high-pressure fuel accumulator is attached to the cylinder head.
  • the fluid-tight passages are completely formed by the said main line of the high-pressure fuel accumulator.
  • This device has the disadvantage of an increased risk of leaks, allowing fuel to escape from the high pressure fuel reservoir, unless otherwise precautions are taken.
  • the fuel supply device comprises a fuel distribution element extending along a longitudinal direction and at least one connecting element extending transversely to the longitudinal direction, via which the fuel distribution element can be connected to the internal combustion engine.
  • a fuel rail for supplying fuel to injectors of an internal combustion engine having a manifold for receiving pressurized fuel having a fuel inlet and a plurality of injector receptacles.
  • the distributor tube can be fixed to the combustion engine via at least one fastening element guided by a sleeve.
  • the sleeve passes through the manifold and is tightly joined to the manifold.
  • the EP 2 317 118 A2 discloses a fuel rail for supplying fuel to injectors of a fuel-injection engine having a manifold for receiving pressurized fuel, wherein branch bores are provided in the manifold, to each of which a branch line is connected via a connection adapter. It is provided that each connection adapter is a one-piece deep-drawn part or a one-piece extruded part and has a matched to the outer contour of the manifold mounting flange, via which the connection adapter is joined to the manifold.

  • the stiffening element has at least one passage opening through which a connecting means for connecting the stiffening element to the connecting element and / or the fuel distribution element is introduced.
  • the fuel supply device comprises two stiffening elements, which are each connected on the one hand with the outer circumferential surface of the fuel distribution element and on the other hand with the connecting element outside, in particular exclusively outside, of the fuel distribution element.
  • the connecting element penetrates the fuel distribution element and projects beyond it in the axial direction of the connecting element on both sides, ie on both an upper and on an underside by a certain distance.
  • One of the two connecting elements is now arranged on the upper side of the fuel distribution element and on the one hand with the outer circumferential surface desselbigen and on the other hand connected to the connecting element.
  • the second of the stiffening elements is then arranged on the underside and connected on the one hand to the outer circumferential surface of the fuel distribution element and on the other hand to the connecting element.
  • the connection of the connecting element with the fuel distribution element is particularly strong.

  • the stiffening element By the stiffening element, the connection between the fuel distribution element, which is also referred to as a fuel rail, stiffened and the connecting element. It follows that the probability of occurrence of leaks and thus leakage of fuel received in the fuel distribution element is significantly reduced.
  • the stiffening element is connected to an outer circumferential surface of the fuel distribution element, a particularly large connecting surface between the stiffening element and the fuel distribution element is available. This results in lower stresses in this interface with very high pressure fuel in the fuel distribution element. This is particularly advantageous if the stiffening element with the fuel distribution element and / or materially connected to the connecting element, in particular soldered, is. Due to the large available connection surface, the mechanical stress is low, for example in the soldering seam. Even with a very high internal pressure of the fuel distribution element and in the presence of biasing forces of the fuel supply device cooperating injectors, the large connection surface is less heavily loaded, whereby a low probability of failure, for example, the solder seam and thus destruction of the entire fuel supply device is given.
  • the advantages outlined here can be achieved without increasing a wall thickness of the fuel distribution element and thus its weight. This keeps the total weight of the fuel supply device in a small frame. Also, the number of attachment points and connecting surfaces between the connecting element and the fuel distribution element can be kept low, which in turn leads to a low weight and low cost of the fuel supply device.
  • a connecting surface between the stiffening element and the connecting element is particularly large, and here also due to the large connecting surface even at a high prevailing in the fuel distribution element internal pressure, in the presence of mechanical biasing forces by fastened injectors and connected to the cylinder head fuel supply device low voltages and thus a low load in the interface. If the stiffening element and the connecting element are soldered to one another, this means a low load on the soldered seam, which has a positive effect on the functional performance of the fuel supply device.
  • the stiffening element is formed as a stiffening plate, which advantageously has a corresponding to an outer contour of the fuel distribution member receptacle in which the fuel distribution element is at least partially received, and which extends obliquely, in particular transversely to the longitudinal direction of the fuel distribution element.
  • the stiffening element thus has a collar shape, through which the fuel supply device is stiffened in the connecting region between the fuel distribution element and the connecting element.
  • the functional performance of the fuel supply device is given in a particularly high degree when the connecting element with the fuel distribution element materially connected, in particular soldered, is.
  • a particularly strong and rigid connection with a long service life is realized in a particularly preferred embodiment of the invention, in which a receiving space between the stiffening element and the connecting element and / or between the stiffening element and the fuel distribution element is formed, in which a connecting means, in particular a connecting means is received for cohesively connecting the stiffening element with the connecting element and / or the stiffening element with the fuel distribution element, such as solder, adhesive and / or the like.
