  • Such housing parts are mostly made of metal, preferably anodized aluminum manufactured.
  • the circumferential between the housing parts Funding is made of plastic and contains Increase in the strength of embedded glass fiber elements. Even after a short period of operation, such Flow pump an increased wear occur. In particular, dirt introduced from the outside can lead to a Abrasion of the anodized layer and the surface of the impeller to lead.
  • an aggregate for Pumping fuel which is a pump chamber has, in which at least parts of the multi-part structure Pump housing are made of ceramic material. This allows a wear-resistant wall of the Pump chamber are created, which also a can reduce unpleasant and unwanted noise.
  • a pump chamber is in internal gear pumps intended. Because of the geometrically simple design Housing parts to form a pump chamber Internal gear pump can be a simple and inexpensive Manufactured from ceramic. This is at Flow pumps are not given as the the pump chamber forming housing parts a relatively complicated have geometric configuration. It is also known from DE 15 28 689A a turbine liquid pump, in which the housing, the cover and the turbine are made of plastic Material are made and sliding surfaces made of stainless steel, chromed metal or the like and are firmly connected to the housing or cover.
  • the unit according to the invention with the characteristic Features of claim 1 has the advantage that an inexpensive design of a pump chamber can be given, which also has a long service life due to the at least one pointing to the funding has wear-resistant insert. This allows the areas subject to heavy wear Pump chamber with wear-resistant inserts, so that for the rest on inexpensive materials can be used, which is mostly also a simple one Enable manufacturing. At the same time, this shows Design according to the invention has the advantage that a reduces unpleasant and unwanted noise can be.
  • FIG. 1 shows an aggregate for conveying of fuel with one shown in longitudinal section
  • Figure 2 is a view Arrow II in Figure 1 on the wear-resistant insert
  • Figure 3 the flow pump in longitudinal section with the use according to a second embodiment
  • Figure 4 the flow pump in longitudinal section with the use according to a third embodiment.
  • a unit shown in Figure 1 is used to convey Fuel from a storage tank, not shown also not shown internal combustion engine one Motor vehicle.
  • the fuel delivery unit has one Flow pump 11 on with a funding 12 in the form of an impeller that is not with one by one shown electric drive motor driven shaft 13 is rotationally connected.
  • the flow pump 11 can as a peripheral pump or as described below Embodiment to be designed as a side channel pump.
  • the shaft 13 penetrates the impeller 12 and is against one Intake cover 16.
  • the intake cover 16 closes this Fuel delivery unit 10 on its intake side Face.
  • the impeller 12 is in a pump chamber 7 arranged in the direction of the axis of rotation 15 of the impeller 12 seen on both sides is delimited by walls 18, 19.
  • the flow pump 11 fuel through an intake port 26 in the intake cover 16 and presses this medium over one Pump outlet 28 in an intermediate housing 21 in a room 29, in which the drive motor, not shown is housed. From there, the fuel is over an outlet or pressure port 31 of the internal combustion engine fed.
  • the fuel delivery unit can within the Fuel tanks may be arranged or outside the Fuel tanks.
  • the intake cover 16 is according to one in FIGS. 1 and 2 illustrated first embodiment of the flow pump formed in two parts and has a wear-resistant Insert 51, which is preferably made of ceramic.
  • This Insert 51 is in a receptacle 52 made of plastic formed housing section 53 of the intake cover 16 added.
  • the receptacle 52 of the housing section 53 is in the Longitudinal section considered essentially U-shaped and the insert 51 is inserted in this.
  • the mission 51 can with the housing section 53 force and / or be positively connected.
  • the insert 51 is inserted in the receptacle 52, clipped in, snapped in or partially made of the material of the Housing section 53 is overmolded.
  • the housing section 53 made of plastic can also with a complicated outer contour of the intake cover 16 in a simple manner, for example by injection molding, getting produced. This also has the advantage that the suction cover 16 in already existing Assembly systems can be processed without retrofitting.
  • the insert 51 is essentially plate-shaped and the first shown in Figure 2
  • the insert 51 forms the entire wall 18 and has a delivery channel 41.
  • the insert 51 only partially the wall 18 forms, while the rest of the wall 18 through the Housing section 53 is formed.
  • the Insert 51 the wall 18 where the impeller 12 is due to from occurring during the operation of the flow pump 11 Compressive forces on the wall 18 in the direction of its axis of rotation 15 supported.
  • insert 51 may be close in a ring shape the outer circumference of the impeller 12 outside of Delivery channel 41 may be arranged or disc-shaped within the conveyor channel 41.
  • the insert 51 has Bores 56, into the pin 57 of the housing section 53 intervene to fix it.
  • the insert 51 points furthermore has a bore 59 which is connected to the intake port 26 is aligned so that fuel in the pump chamber 17th can flow in.
  • the insert 51 can also be a Have recess 58 into which the end of the shaft 13 dips.
  • the insert 51 executed with a small thickness, so that this essentially only a wear-resistant contact surface for forms the impeller 12.
  • the insert 51 can for example as one on the housing section 53 of the Suction cover 16 applied coating to be executed.
  • the insert 51 can also be used as a thin plate be formed, which is connected to the housing portion 53 is, for example, of the plastic material of the Housing section 53 is overmolded.
