  • the filter device is then arranged on the pressure side of the pump, wherein the pump can suck the fuel, for example from the fuel tank via an intermediate pre-filter.
  • connection channel leads from a filter outlet to a pump inlet.
  • the fuel pump then sucks the fuel out of the filter device into which the fuel flows out of the tank.
  • the filter device in general a reduced pressure, since the fuel is sucked from there.
  • the filter device can take over the function of a possibly necessary pre-filter for the pump.
  • the connecting channel forms the essential part of a flow connection between the pump and the pump Forms filter device, so that additional hose or pipe connections from the pump to the filter device are not needed.

  • the housing has at least one cover part and an at least partially formed connecting channel.
  • At least one second fuel outlet is provided for connecting a pressure control device.
  • a pressure control device is particularly preferably designed as a pressure regulator and can be fastened to the housing. Unlike in known from the prior art solutions in which a pressure regulator on Flange of the tank installation unit is connected, can be dispensed with this measure on hose or pipe pieces for connecting the pressure regulator with the fuel delivery device. Through this solution effort during assembly is saved.
  • This embodiment is particularly preferred when at least two outlets are provided on the housing. One outlet then serves as drain to the motor and the second to connect a pressure regulator.
  • the pressure control device may also be provided within the housing, wherein the fuel inlet is connected to the fuel outlet of the pump or the filter device and to a Kraftstoffauslassstutzen the conveyor and having a second outlet which is closed by the pressure control valve and opens into the tank space.
  • all fuel outlets are arranged on the cover part.
  • a part of the housing forms the pump housing, so that a separate housing for the fuel pump is not needed.
  • the pump housing may be part of the inner wall of the housing in this development.
  • the pump housing is formed by a part of the body part. Accordingly, preferably, the housing may at least partially form the housing for the filter device.
  • a likewise cylindrical cavity can remain in the center, which can be surrounded by an inner boundary wall.
  • the inner boundary wall can simultaneously serve as a motor housing for the fuel pump, so that a total of material for housing walls can be saved.
  • a flexible coupling between the fuel pump and the housing is arranged, whereby the transmission of vibrations from the fuel pump to the housing can be suppressed.
  • At least one opening for carrying out the electrical connections of the fuel pump is provided in the cover part.
  • a particularly simple construction is made possible, in which the Fuel drainage and the electrical connection via the cover part takes place, so that a particularly simple assembly is possible.

It has a formed with a hollow cylindrical partition 6 , downwardly open inner chamber 7 for receiving the fuel pump 2 and a concentric thereto, open at the top outer chamber 8 for receiving the filter element 3, the outwardly via a hollow cylindrical outer wall 12 and down through arranged between intermediate wall 6 and outer wall 12 , annular disc-shaped bottom is completed on.
  • the radially outer space of the outer chamber 8 forms the dirty side 9 and the inner space separated therefrom by the filter insert 3 forms the clean side 11 of the filter insert 3 .
  • the filter insert 3 may be formed, for example, with a wound filter or as a star filter insert.
  • a fuel inlet 13 is provided.
  • the cover part 5 is seated on top of a radially projecting from the upper edge of the outer wall 12 and outwardly annular annular web of the body part 4 , wherein it preferably welded to this, but may also be connected thereto, for example via clip elements.

When the pressure input is at a pressure which generates a pressure force greater than the biasing force acting on the valve closure member, the valve closure member lifts from the valve seat and releases a certain passage area, so that the fuel can overflow to the pressure outlet.
