Definitions

  • the invention relates to an electrically driven air pump, for example for Motor vehicles in which so-called secondary air is conveyed into the exhaust pipe system should be to improve the exhaust gas values.
  • the invention has for its object an air pump with reduced To create running noise, spraying a metal reinforcement with the Pump cover wall should be possible.
  • FIG. 1 shows the air pump 1 according to the invention, consisting of a plastic Manufactured housing 2, which houses a pump unit 3 on the one hand and on the other hand an electric motor 4.
  • the housing 1 is on the electric motor side by a cover 5 closed and has led out electrical connection cable 6 for the Electric motor 4.
  • the pump station side is closed by a pump cover 7, which has an air supply connection 8.
  • a stator 9 having guide channels 10 with which in turn the air conveyed by a first impeller 11 from the outer impeller outlet 12 the inner impeller inlet 13 of a further impeller 14 is supplied.
  • the Housing 2 has an annular channel 15 in the area of the last impeller 14, in which the air exits the impeller 14 and is led to a pressure connection.
  • the two impellers 11, 14 are with their hubs 16 on a shaft 17 of the Fixed electric motor 4, which protrudes into the pump station side.
  • the electric motor 4 is in a recess by means of a first elastomer ring 18 19 a housing wall separating the pump station side from the electric motor side 20 and a second elastomer ring 21 held.
  • the pump cover made of plastic 7 a metal reinforcement 23 sprayed with an axial wall 22 of the pump cover 7 has, with its outer surface or its edge 24 made of plastic or the pump cover wall protrudes and its inner jacket surface or inner edge 25 interrupted by a plurality of openings 26 arranged in a star shape is, as can be seen from Figure 2, a view of the metal reinforcement 23 from Figure 1 shows.
  • openings 26 are filled with plastic during the pressure spraying process form plastic walls 27 that exist on both sides of the metal reinforcement 23 Connect axial walls 28, 29 of the axial wall 22.
  • the one after the spraying process shrinking process of the plastic against the metal can now take place without Stress build up because the outer edge 24 of the metal reinforcement 23 from the Plastic or the pump cover wall can slide out and also the between the openings 26 existing plastic walls 27 from the star shape arranged openings 26.
