Definitions

• Filter module for a fuel delivery unit and fuel delivery unit for a motor vehicle
• the invention relates to a filter module for a fuel delivery unit of a motor vehicle, in which the fuel delivery unit has a fuel pump with at least two inlet areas and two independent delivery chambers. Furthermore, the invention relates to a fuel delivery unit for a motor vehicle with a fuel pump having at least two delivery chambers, each with an inlet area of the delivery chambers and with a filter module for filtering the fuel flowing into the inlet areas.
• filter modules each with a filter fabric for each of the inlet areas, are used on the feed pump.
• one of the delivery chambers is used to deliver fuel from a baffle to an internal combustion engine of the motor vehicle.
• the second delivery chamber which is separate from the first delivery chamber, serves to deliver fuel into the baffle.
• the suction jet pump conveys fuel from the fuel tank into the baffle.
• the filter fabric ⁇ can have an intended mesh size for the respective application.
• a disadvantage of the known filter module is that it is expensive to manufacture and requires complex assembly. As a result, the fuel delivery unit with the filter module is also very complex.
• the invention is based on the problem of designing a filter module of the type mentioned at the outset in such a way that it can be produced particularly cost-effectively. Furthermore, a fuel delivery unit of particularly simple construction is to be created. "
• the first-mentioned problem is solved according to the invention in that a common filter area is provided for both inlet areas.
• the filter module according to the invention requires a particularly low manufacturing outlay for the filter area. Thanks to the invention, the filter area can be manufactured in one piece for both inlet areas and thus in a particularly cost-effective manner. Furthermore, the two filter areas can be installed particularly easily in one operation.
• the filter module according to the invention could have a separate connection piece for each of the inlet areas.
• the filter module according to the invention is structurally particularly simple if it has a single connecting piece for both inlet areas.
• the second-mentioned problem namely the creation of a fuel delivery unit of particularly simple construction, is solved according to the invention in that the filter module has a common filter area connected to both inlet areas of the fuel pump.
• the fuel delivery unit is particularly compact and requires very few components to be assembled. A complex attachment of several filter areas to the feed pump is avoided thanks to the invention.
• the fuel delivery unit is therefore of a particularly simple construction.
• the housing part has a partition wall which extends up to the housing of the filter module.
• FIG. 1 shows a schematic representation of a fuel delivery unit used in a swirl pot in longitudinal section
• FIG. 2 shows a sectional view through a connection of a filter module of the fuel delivery unit from FIG. 1 along the line II-II,
• FIG. 3 shows a sectional view through the fuel delivery unit from FIG. 1 in the region of a suction jet pump
• FIG. 4 shows a further embodiment of the fuel delivery unit in longitudinal section.
• FIG. 1 shows schematically the area of a fuel delivery unit 2 facing the bottom of a fuel tank 1 in a longitudinal section.
• the fuel delivery unit 2 is mounted within a baffle 3 and has a fuel pump 5 driven by an electric motor 4.
• the fuel pump 5 has an impeller 8 which is rotatably arranged between two housing parts 6, 7.
• the housing parts 6, 7 are kept at a distance by means of a spacer ring 9.
• the impeller 8 has a plurality of rings 10 - 12 of vane chambers delimiting guide vanes in its end faces.
• the rings 10 - 12 are arranged opposite each other in part-annular channels 13 - 15.
• the partially annular channels 13 - 15 and the vane chambers each form delivery chambers 20, 21 extending from inlet areas 16, 17 to outlet areas 18, 19.
• the fuel pump 5 thus operates on the principle of the side channel pump.
• the innermost of the delivery chambers 21 serves to supply a suction jet pump 22 shown in FIG. 3 with propellant.
• the radially outer rings 10, 11 of the vane chambers are interconnected and, with the corresponding part-ring-shaped channels 13, 14, form a single delivery chamber 20 for delivering fuel to an internal combustion engine (not shown) of the motor vehicle.
• the fuel delivery unit 2 has a filter module 23 for both inlet areas 16, 17 with a common filter area 24 arranged in the baffle 3.
• the filter area 24 can be, for example, a filter fabric with an intended mesh size.
• the filter area 24 can have a plurality of filter fabrics arranged one above the other with different mesh sizes, so that the fuel is first filtered roughly and then finely.
• the filter area 24 is arranged on a connecting piece 25.
• the connecting piece 25 is inserted into the housing part 7 having the inlet regions 16, 17 and sealed by means of a sealing ring 26.
• Figure 2 shows the connection of the Connection piece 25 with the housing part 7 in the area of the sealing ring 26 in a sectional view along the line II - II from Figure 1. It can be seen here that the housing part 7 has recesses 27 with a radius r at the inlet areas 16, 17 and that Merge radii r.
• the connecting piece 25 is shaped accordingly and inserted into the recess 27.
• FIG. 3 shows a sectional view through the fuel delivery unit 2 from FIG. 1 in the area of the suction jet pump 22.
• the housing part 7 having the inlet areas 16, 17 has a receptacle 28 for the suction jet pump 22.
• the suction jet pump 22 is made in one piece with a nozzle 29 and a mixing tube 30 and inserted into the receptacle 28.
• the mixing tube 30 and the nozzle 29 are connected to one another via webs 31.
• the mixing tube 30 is guided into the swirl pot 3.
• FIG. 4 shows a further embodiment of the fuel delivery unit 32 according to the invention in longitudinal section. This differs from that of FIG. 1 primarily in that inlet regions 33, 34 are separated from one another by a partition 36 arranged in a housing part 35.
• a filter module 37 with a common filter area 38 likewise has a partition 40 in a connecting piece 39. This partition 40 is separated from the housing part 35 up to a second filter area 41. leads.
• This second filter area 41 is arranged behind the common filter area 38, viewed in the direction of flow, and has a particularly small pore size.
• the common filter area 38 is therefore used for the coarse filtering, while the second filter area 41 is provided for the fine filtering of the fuel supplied to the internal combustion engine.
