Definitions
- the invention relates to a delivery unit with a pump wall having pump, with a on the pump wall in the Area of an inlet channel to be attached filter element and with tensioning devices to pre-tension the filter element the pump wall, the filter element suction openings having.
- the Conveyor unit usually forms with one to drive the Pump provided electric motor a pre-assembled unit.
- the inlet channel here has one protruding from the pump wall Pipe socket on which a connector of the filter element is plugged on (DE 44 31 788 A1). Then will the connector on the pipe socket using a pipe clamp secured.
- a disadvantage of the known delivery unit is that the pump wall difficult due to the protruding pipe socket represents manufacturing component. This creates the Conveyor unit very expensive. Furthermore, the filter element through the pipe socket a very large distance of the pump wall, making the delivery unit very bulky component represents.
- the invention is based on the problem of a conveyor unit of the type mentioned in the beginning so that they are special is inexpensive to manufacture and the smallest possible dimensions having.
- the filter element is in direct contact the pump wall having the inlet duct.
- a pipe socket to attach the filter element as in the known Conveyor unit is therefore no longer required.
- the suction opening is particularly close to the pump wall and thus arranged the inlet duct. This leads to special low height of the filter element.
- the suction opening requires of the inlet duct thanks to the invention exclusively a distance required for the assembly of the clamping devices.
- the invention Conveyor unit particularly compact.
- the pump wall and the one on the pump wall adjacent side of the filter element can thanks to the invention each be designed flat.
- the pump wall and the filter element therefore make components that are particularly simple and inexpensive to manufacture
- the conveyor unit according to the invention is suitable due to its inexpensive Design not only to deliver fuel, but also for example, for conveying washing liquid from a windscreen washer system.
- the filter element could be pretensioned against the pump wall are generated, for example, by the filter element between the pump wall and a bottom of the container is clamped.
- the conveyor unit according to the invention can be particularly inexpensive pre-assemble to a structural unit if they have a clamping element for biasing the filter element.
- the tensioning element could, for example, be attached to the pump Clamping bracket to be formed overlap the filter element.
- the tensioning element is designed according to another advantageous one Development of the invention structurally particularly simple if that Clamping element made from a sheet metal strip and an edge of the filter element and an edge of the pump is designed behind.
- a clamping element to be fastened separately advantageous development of the invention can be dispensed with if the Clamping element in one piece with a housing of the conveyor unit or Pump is made and one adjacent to the edge of the filter element Has flanging.
- Such flanging is usually necessary anyway to clamp individual components of the pump together.
- the manufacturing costs for the conveyor unit according to the invention kept particularly low.
- the filter element as a result, particularly in the case of strong vibrations of the motor vehicle reliably attached to the pump.
- Conveyor unit helps if the ceramic pump wall in the Sintering process is made. Because the pump wall thanks to the invention can be designed, is necessary for the manufacture of the pump wall Sintered mold has a particularly simple structure and is easy to demold axially. Furthermore, ceramics used in sintering technology have a special high surface hardness, high compressive strength and good Corrosion resistance, so that the conveyor unit is particularly high Has lifespan. Silicon carbide, for example, is suitable as the ceramic or oxide ceramics.
- the particularly long life of the invention Conveyor unit is particularly necessary if the conveyor unit for use in an inexpensive blow molding process Fuel tank is provided. Here is the conveyor unit trapped in the fuel tank after blowing and can no longer be removed. Another advantage of this design is that there is noise inside the pump particularly well insulated due to the ceramic pump wall become.
- the invention allows numerous embodiments. For further clarification its basic principle is shown in the drawing and is described below.
- This shows in a single figure a conveyor unit 1 according to the invention with one of an electric motor 2 driven pump 3 and a filter element 4.
- the electric motor 2 and the pump 3 are in a common pot-shaped housing 5 arranged.
- the pump 3 is designed as a side channel pump and has an impeller 6 driven by the electric motor 2, which between two fixed pump walls 7, 8 rotates.
- the pump walls 7, 8 are of a tubular, the impeller 6 concentric enclosing spacer 9 held in its intended position.
- the spacer 9 has a slightly larger width than the impeller 6 on.
- In the pump wall 7 facing the filter element 4 is a Inlet duct 10 arranged.
- In the other pump wall 8 is an outlet channel 11 incorporated.
- the filter element 4 has a filter housing 12 with a filter insert 13 arranged therein.
- the filter insert 13 can be made of foam, for example.
- the housing 5 of the conveyor unit 1 is facing the filter element 4 Side made in one piece with a clamping element 18.
- the Clamping element 18 has a circumferential edge 19 to engage behind of the filter housing 12 a flanging 20. This will make the filter housing 12 against the pump wall having the inlet duct 10 7 biased and at the same time the individual components of the pump 3 and of the electric motor 2 clamped together.
- the electric motor 2 the pump 3 and the filter element 4 can simply be inserted into the pot-shaped housing 5.
