Definitions

  • the invention is based on a fuel distributor according to the preamble of claim 1.
  • a fuel distributor has already been proposed which serves to supply several fuel injectors of the top feed type and which has an inlet and a return nozzle and also has a number of connecting pieces corresponding to the number of fuel injectors into which the fuel injectors with their fuel supply ports can be inserted tightly.
  • This fuel distributor has the disadvantage that the inlet connection and the return connection are arranged at two opposite ends of the fuel distributor.
  • the pressure regulator is arranged on the side of the housing of the fuel distributor.
  • This proposed fuel distributor requires a large amount of space and can be connected to fuel supply lines and return lines only in a comparatively complicated manner.
  • the inlet connection and return connection are arranged in spatial proximity to one another at one end of the fuel distributor or at least in the vicinity of one end are and so a one-sided connection of the fuel distributor is possible.
  • the assembly of the fuel distributor e.g. in the engine compartment of a vehicle is facilitated and the space required is reduced or the available space at a suitable point is better utilized.
  • the fuel distributor according to the invention can be produced in a simple, inexpensive manner.
  • connection cover is arranged on the end face of the first end of the distributor housing and if the return port is centrally located on the connection cover and the inlet connection near the first End of the distributor housing is formed.
  • the return line is in a guide section of the connection cover is inserted and has a collar with which it projects into a receiving section of the connection cover and a bushing engaging the collar fixes the return line in the receiving section.
  • At least one spacer is arranged in the inlet cross section of the distributor housing between the wall of the inlet cross section and the return line, which limits the offset of the return line with respect to the longitudinal axis of the distributor housing. This simplifies the assembly of the pressure regulator in the distributor housing and reduces the risk of the sealing rings arranged on the circumference of the pressure regulator being cut.
  • the spacer has a plurality of cams which point radially inward perpendicular to the longitudinal axis of the distributor housing and which lie opposite a collar of the return line in the radial direction.
  • At least one slot perpendicular to the longitudinal axis is formed on the periphery of the distributor housing at its second end receiving the pressure regulator, through which a retaining clip partially projects and with a bias in the direction of the longitudinal axis is applied to the circumference of the pressure regulator.
  • a recess is provided on an end face of the distributor housing facing the connection cover, which recess interacts with a positioning lug formed on one end side of the connection cover, so that rotation of the connection cover relative to the distributor housing is prevented.
  • annular chamber is formed in the sealing ring in the direction of the longitudinal axis of the distributor housing between a support flange on the circumference of the connecting cover and a contact surface of the distributor housing and between the circumference of the connecting cover and the wall of the inlet cross section of the distributor housing is arranged.
