Embodiment Construction
[0040] figure 1 A fuel injection system 1 with a fuel guide part 2 and an assembly 3 for connecting a fuel injection valve 5 ( figure 2 ) of the joint piece 4 is connected to the cup seat 6 of the fuel guide part 2 . The fuel guiding part 2 here has a tubular base body 7 and a cup 6 , wherein, in addition to the cup 6 , further cups are fastened to the tubular base 7 , preferably along the axial extension of the tubular base 7 superior. To simplify the illustration, only a section of the tubular base body 7 is shown here, wherein the tubular base body 7 extends along its axis 8 over a sufficient length.
[0041] In this exemplary embodiment, the tubular main body 7 can be part of the fuel-carrying component 2 designed as a fuel distributor 2 , in particular a fuel distribution rail 2 . The interior space 9 of the tubular base body 7 then serves as a fuel accumulator in order to store fuel under high pressure and to distribute the fuel via a corresponding number of cups 6 t...
