Definitions

  • the invention relates to a conveyor unit with a
  • the delivery unit is used to deliver fuel from a fuel tank to an internal combustion engine of a motor vehicle.
  • the filters known for this purpose are separate components, which are mounted on the bottom of the swirl pot, so that the filter is in the fuel tank even when the level is low
  • Fuel is located.
  • a correspondingly small mesh size of the filter fabric ensures that the entire surface of the filter is wetted with fuel, even if the filter is only partially immersed in the fuel. Due to the installation of the filter under the bottom of the conveyor unit, the installation space required for the conveyor unit in the axial direction increases to a not inconsiderable extent. Since today's fuel tanks are becoming increasingly flat, it is increasingly learn to integrate such delivery units in the fuel tank.
  • the object is achieved in that channels are arranged on the side of the swirl pot facing the tank bottom. are designed such that fuel can flow from the periphery of the swirl pot to the inlet opening, and that filter-forming shaped elements are arranged in the channels.
  • the swirl pot of the conveyor unit according to the invention thus enables relatively flat filters, which require particularly little installation space in axial extension.
  • the channels on the underside of the baffle ensure that the radial inflowing fuel is now directed to the inlet opening. This ensures a reliable fuel supply to the inlet opening even when the fuel tank is low.
  • the regions of the bottom of the baffle that form the channels are offset inwards relative to the remaining regions of the bottom.
  • the manufacture of the surge pot by means of injection molding is simplified in that the bottom of the surge pot has an almost uniform wall thickness.
  • a pocket formation on the inside of the swirl pot, depending on the channel design, is advantageously counteracted by a targeted arrangement of the suction area of the fuel pump in the largest pocket.
  • At least two, preferably three or four, channels are arranged on the bottom of the swirl pot.
  • the channels at the bottom of the baffle can be designed in any way. The formation of the channels with a course beginning at the circumference of the surge pot and then tapering has proven to be advantageous.
  • An increase in the degree of filtering by reducing the gap width with a constant flow cross-section is achieved in that at least one shaped element is not in contact with the tank bottom and the area thus created between the end face of the shaped element and the tank bottom is now part of the flow cross-section of the filter.
  • the geometrical dimensions and the spacing of the shaped elements can be adapted to the prevailing conditions of use.
  • FIG. 2 a perspective view of the surge pot of the conveyor unit according to FIG. 1
  • 3 a second embodiment of the surge pot according to FIG. 1
  • the fuel tank 1 shown in FIG. 1 contains a delivery unit 2.
  • the delivery unit 2 is inserted through an opening 3 in the fuel tank 1, a flange 4 closing the opening 3 in the fuel tank 1.
  • the delivery unit 2 comprises a swirl pot 5 for receiving fuel and a fuel pump 6 arranged therein, which pumps the fuel to an internal combustion engine (not shown) of the motor vehicle.
  • the delivery unit 2 sits on the tank bottom 9 with the swirl pot 5.
  • FIG. 2 shows the top view on the bottom 7 of the swirl pot 5 from FIG. 1.
  • the bottom 7 has an inlet opening 8 through which fuel from the fuel tank 1 enters the swirl pot 5.
  • the inlet opening 8 is provided with spacers 10.
  • Channels 11 are arranged in the bottom 7 of the surge pot 5 and are designed as inwardly offset regions. The channels 11 run from the radially outer edge of the base 7 of the baffle 5 to the inlet opening 8, with a tapering profile with respect to the radially outer edge.
  • the surge pot 5 stands on the tank bottom 9.
  • Shaped elements 13 are arranged in the radially outer region of each channel 11, which form a filter 14 in each channel 11, so that three channels 14 are present in three channels 11.
  • the fuel in the fuel tank 1 flows through the filter ter 14 and the channels 11 to the inlet opening 8, through which it enters the baffle 5.
  • the surge pot 5 shown in FIG. 3 has contact elements 14 with which it stands on the tank bottom, not shown.
  • the contact elements 15 are designed such that they form lateral boundaries of the channels 11, via which fuel can flow from the fuel tank to the inlet opening 8 and thus into the surge pot 5.
  • Shaped elements 13 form a filter 14 in each channel 11 so that the particles in the fuel do not get into the swirl pot 5 and thus into the suction area of the fuel pump.
  • the surge pot 5 in FIG. 4 has a base 7, in which the channels 11 are formed as regions offset inwards. In the interior of the surge pot 5, the bottom 7 is flat. As a result, the bottom 7 in the areas 12 with which the baffle 5 sits on the tank bottom has a greater wall thickness than in the area of the channels 11.
  • the channels 11 in the surge pot 5 according to FIG. 5 are also designed as inwardly offset regions.
  • the bottom 7 of the baffle 5 has approximately the same wall thickness in all areas, so that the channels 11 form as elevations and the areas 12 form pockets 16 in the interior of the baffle 5.
  • the size of the pockets 16 can be influenced by targeted design of the channels 11.
  • the fuel pump 6 is arranged with its suction area in the largest pocket 16.
