Definitions

  • the invention relates to an impeller for a particular trained as a side channel pump or as a peripheral pump Feed pump, which has one in each end Wreath has vane bounding vanes and a driver for its rotationally fixed attachment has a correspondingly designed drive.
  • Such wheels usually have a non-round at their center Recess as a driver and can be on a Attach the shaft of an electric motor on which the impellers are stored with axial play.
  • the impellers are made of plastic by injection molding or sintered.
  • the one equipped with such an impeller Feed pump is often used as a fuel pump in today Motor vehicles used.
  • the guide vanes usually have to be reached a very large angle of inclination to the perpendicular to the Front of the impeller. Facing each other Blade chambers are for axially flowed impellers also connected to each other.
  • a disadvantage of the known Impeller is that it is very difficult to demold.
  • a Injection mold an injection die or a mold must be pulled apart during a rotary movement become. Furthermore, the impeller requires a core for the driver, as this is usually perpendicular to the end faces the impeller is aligned. This leads to a very expensive manufacture of the impeller.
  • the invention is based on the problem of an impeller type mentioned so that it is very can be produced inexpensively and that a provided with it Feed pump has a particularly high efficiency.
  • the impeller consists of at least two superimposed ones Washer parts are assembled and that the washer parts are non-rotatably connected.
  • the impeller-equipped feed pump has a non-rotatable design the connection of the disc parts a very high Efficiency. Thanks to the invention can be almost any design guide vanes and connections to each other Manufacture opposite vane chambers.
  • the two are Disc parts on a driver located in their center pressed on.
  • the driver has one of the Circular shape deviating outer contour, preferably one Square contour, on. But there are also other contours, e.g. B. tooth profile, possible.
  • the driver also has a receptacle for the drive shaft of the electric motor. In the simplest case, this mount is a hole which is flattened at one point on its circumference having. Because the driver is usually in the center of the wheel is arranged, it is not necessary for all To provide panes with a driver.
  • each of the disc parts can be in one manufacture coreless, two-part form. Designed this way the manufacture of the impeller is very inexpensive.
  • the pane parts can be simply connect the invention together, if the disc parts are outside the center of the impeller are non-rotatably connected.
  • the disc parts are advantageous according to another Development of the invention without additional security against rotation aligned against each other when pressing, if at least one of the disk parts bores for pressing with a non-rotatably connected to the other part of the disc Has cones.
  • the impeller according to the invention consists of a particularly few Components if the pin is in one piece with one of the Disc parts are designed.
  • the disc parts can be according to another advantageous To make the development of the invention identical, if the pins are arranged in bores. This Design leads to a sharp reduction in costs for the manufacture of the impeller according to the invention necessary tools. For reliable pressing, for example, two or more cylinder pins are suitable or dowel pins.
  • the impeller according to the invention has regardless of the Impeller prevailing pressures a designated height when the pane parts glued or welded together are. This design also leads to a special one high efficiency of the impeller according to the invention provided feed pump.
  • the gluing or welding can be used alone or in addition to the positive connection the disc parts are used. For example can be glued to the number of for the Keep the required pins low.
  • pane parts can also be identified as identical Manufacture components. For example, as a welding process mirror welding can be used.
  • the impeller however requires only very little reworking, if the welding process is ultrasonic welding is used.
  • Impeller contributes when one of the disc parts Has recesses and if the other disc part locking hooks penetrating into the locking recesses Has.
  • the disc parts are advantageous according to another Further development of the invention reliably against each other preloaded when the washer parts have a bayonet lock for their connection.
  • the feed pump 2 has a rotatably arranged in a housing 3, on a Shaft 5 of the electric motor 1 attached impeller 4.
  • the housing 3 has an inlet channel 6 on one side and on the side opposite the inlet duct 6 Outlet channel 7 on.
  • the impeller 4 consists of two disc parts 8 which are integrally connected to one another, 9 together.
  • the integral connection of the pane parts 8, 9 can for example by gluing or Welding, for example in the ultrasonic process, be generated.
  • the disk parts 8, 9 each have one Wreath vane chambers 10, 11 delimiting guide vanes 12, 13.
  • Vane chambers facing each other 10, 11 are each connected to one another via a channel 14.
  • the housing 3 In the guide vanes 12, 13 of the disc parts 8, 9 opposite areas, the housing 3 each seen in the direction of rotation of the impeller 4 from the height of the inlet duct 6 to the height of the Exhaust duct 7 extending, partially annular duct 15, 16 on.
  • the vane chambers 10, 11 and the part-ring-shaped Channels 15, 16 form a delivery chamber for one promoting liquid.
  • the Channels 14 for connecting the opposing Blade chambers 10, 11 can be one of the angle of inclination of the guide vanes 12, 13 deviating angles have and for example perpendicular to the end face of the Impeller 4 be aligned.
  • FIG 2 shows a longitudinal section through another Embodiment of the impeller according to the invention.
  • the Impeller has a driver 17 with a in its center Square 18, with which it relates to a not shown, Arrange the correspondingly designed drive so that it cannot rotate leaves.
  • the impeller has two disc parts 19, 20 and a wreath of vane chambers in each of its end faces 21, 22 guiding vanes 23, 24 opposite blade chambers 21, 22 overlap itself, so that a medium to be promoted by one Flow over the blade chamber 21 into the other blade chamber 22 can.
  • the Disk parts 19, 20 with one another via a bayonet catch 25 be connected.
  • the bayonet lock 25 serves in this case at the same time as an anti-rotation device.
  • FIG. 3 shows a further embodiment of the invention Impeller in which two disc parts 26, 27 are pressed together. For this has one of the disc parts 26 a protruding collar 28 and the other Disk part 27 has a recess 29 for receiving the federal government 28.
  • the collar 28 is outside of vane chambers 30, 31 delimiting guide vanes 32, 33 are arranged. As in the impeller of Figure 1 are opposed to each other Blade chambers 30, 31 connected to one another via channels 34.
  • FIG. 4 shows a sectional view through the Impeller from Figure 3 along the line IV - IV that the the disc part 27 having the recess 29 a radial has outwardly into the recess 29 facing nose 35 and between ends of the collar 28 of the one shown in Figure 3 Disk part 26 is clamped. This makes them Disk parts 26, 27 rotatably in an intended position connected to each other.
  • FIG. 5 shows a further embodiment of the invention Impeller in which opposing Washer parts 36, 37 by means of a snap-in connection 38 are interconnected.
  • Impeller in which opposing Washer parts 36, 37 by means of a snap-in connection 38 are interconnected.
  • the disc parts 37 protruding in the radial direction of the Impeller elastically designed locking hooks 39, which are in locking recesses 40 penetrate the other disc part 36.
  • FIG. 6 shows a further embodiment of the invention Impeller in which two disc parts 41, 42 for their pressing holes 43 - 45.
  • One of the disc parts 41 is made in one piece with a pin 46.
  • a pin 47 penetrates mutually opposing bores 44, 45 of the disk parts 41, 42.
  • the disc parts 41, 42 either exclusively the holes 44, 45 for those to be used separately Have pins 47 or in one piece with one of the disk parts 41 have pins 46 produced.
