Definitions

  • Fuel injection system with at least one such arrangement.
  • the invention relates to the field of fuel injection systems for internal combustion engines.
  • Component is preferably carried out by a cohesive connection, in particular by brazing.
  • the development according to claim 6 has the advantage that a high mechanical stability and ease of mounting are possible. It is particularly advantageous if the connecting part is formed from a metal sheet, as in claim 8
  • the connecting parts are provided. This can be dispensed with a one-piece cast construction, each comprising a holding part and a connection part, which allows a significant cost savings. Thus, a voltage optimized design can be realized without a cast construction.
  • the connecting part 9 is suitably connected to the intermediate piece 18.
  • the connecting part 8 is connected to the connecting part 9 by means of the intermediate piece 18.
  • an indirect connection is possible, as described for example with reference to FIG. 5.

Abstract

L'invention concerne un ensemble (2) pour des systèmes d'injection de carburant destiné à relier une soupape d'injection de carburant à un composant (3) guidant le carburant. Ledit ensemble comporte une partie de retenue (7), qui sert à la fixation mécanique, et une partie de raccordement (8) à laquelle la soupape d'injection de carburant peut être raccordée hydrauliquement. Une partie de liaison (9) permet de relier la partie de raccordement (9) pouvant être reliée au composant (3) conduisant le carburant à la partie de retenue (7).
