Definitions

  • the development according to claim 2 has the advantage that all fuel outlet openings are on one side and also the fuel feed line. Due to the direct juxtaposition of these lines, inexpensive hose laying can be achieved.
  • the fuel distributor housing 1 constructed according to the invention consists of the two housing halves 2 and 3. Both housing halves are made of plastic or die-cast and are connected to one another in a pressure-tight and leak-proof manner by suitable connecting methods.
  • the housing half 3 has a cup-shaped extension 4.
  • the fuel pressure regulator 5 known per se is installed in this extension. It consists of a membrane 6, which is biased by a spring 7 and presses a closure piece 8 against a bore 9 arranged in the housing half 2.
  • the bore 9 is provided with a hose connection piece 10, which is used to connect a fuel return line to the fuel tank.
  • the bore 9 opens into a chamber 11, which lies below a chamber 12, which is also enclosed by the two housing halves 2 and 3.
  • the chamber 12 is separated from the chamber 11 by a longitudinal wall 13.
  • the longitudinal wall 13 is in equal parts by each case half formed.
  • the chamber 12 is connected to the fuel supply line 14.
  • the 2 shows the inner side of the housing half 2. As can be clearly seen from this, the chamber 12 extends over the entire length of the housing half 2.
  • the fuel feed line 14 is located in its longitudinal center. As a result, the fuel distribution to the individual injection valves (not shown) is made more uniform.
  • the bore 9 for the fuel return line is also in the same horizontal plane as the fuel supply line.
  • the bores 15 extend from the chamber 11 to the individual injection valves.
  • the fuel rail 1 is designed for a four-cylinder reciprocating internal combustion engine.
  • the connection openings 16 are dimensioned such that it is ensured that the required amount of fuel can flow to the injection valves.
  • FIG. 3 shows a cross section through the fuel distributor housing 1 at the level of a connection bore 15 with a connected injection valve 17.
  • the injection valve 17 is fastened to the fuel rail housing 1 against axial displacement by a spring clip 18.
  • the spring clip 18 is held in guide grooves which are embedded in the projections 19 and which allow the spring clip 18 to be displaced in order to release and fasten the injection valve.
