Definitions

  • the invention relates to an electric air pump for a device for flushing a Activated carbon trap and, if necessary, for a temporary leak test on one connected to it Fuel tank system of a vehicle internal combustion engine.
  • Such a device is the subject of the unpublished patent application 197 09 903.3, in which the purge air upstream of the throttle device Internal combustion engine introduced into the air intake system and by an electrical Air pump is conveyed, the direction of delivery is reversed in the leak test becomes.
  • This air pump is a version based on control signals from a Circuit arrangement or a control program of an electronic control unit on and off, and if necessary must be switched according to the direction of rotation.
  • FIG. 1 shows a section of a device 1 for flushing an activated carbon trap 2 and for the temporary leak test of a fuel tank system 3 connected to it a vehicle internal combustion engine 4, in which the purge air from the atmosphere via the Activated carbon trap 2 in an air intake system 5 with a throttle device 6 Internal combustion engine 4 is initiated and the leak test by setting a Test pressure in the hermetically sealed tank system 3 and subsequent Pressure drop measurement, which is detected by a pressure sensor 7, over a period of time done, which provides information about the tightness.
  • the determination of tight or leaky tank system 3 can then be used as a diagnostic value in a control unit 12 can be stored, acoustically or visually displayed. The latter is then done on a display.
  • FIG. 2 shows an electric air pump 8 according to the invention in a sectional view.
  • This electric air pump 8 consists of an electronically commutated electric motor 13, which is arranged together with the air pump in a housing 14, the one has first chamber 15, in which a stand package 16 is arranged, the electrical Connections 17 are guided through a plug cover 18 to the outside, the Plug cover 18 hermetically seals the chamber 15.
  • a second chamber 19 is provided, in which a bell-shaped on a pin 20 trained rotor 21 is arranged which has a cylindrical wall 22 of the area the first chamber 15, in which the stand package 16 is arranged, with the least Exceeds distance and one on the side facing away from the first chamber 15 Has collar 23, the several wing-shaped conveying members typical of peripheral pumps 24 which cooperate with an annular channel 25 which has a separating section 26 (Fig. 3) between two fluid connection piece 27, so that the fluid is sucked through the one nozzle 27 and pressed out of the other, depending reversed according to the direction of rotation.
  • the ring channel 25 is composed of an upper half of the housing 14 and a lower half a pump cover 28 is formed, the pin 20 on the one hand in a bore 29 of the housing 14 and on the other hand, a bore 30 of the pump cover 28 is held becomes.
  • the rotor 21 is fastened on the journal 20 by means of two bearings 31, 32. To increase the bearing distance, the rotor 21 has a hub extension 33, which protrudes into a corresponding bulge 34 of the pump cover 28.
  • the stand assembly 16 is held against rotation by ribs 35 which are arranged on the cylindrical wall 22 of the chamber 15 and engage in corresponding grooves 36 of the stand assembly 16. These ribs 35 serve on the other hand, to reinforce the relatively thin cylindrical wall 22.
  • this wall 22 borders the first chamber 15 opposite the second chamber 19.
  • This magnetic ring 38 is in one piece with the rotor 21 made of plastic sprayed connected or attached to the rotor 21 and attached to its inner circumference is a multi-pole lateral magnetization and is used during motor operation carried along by the traveling magnetic field generated in the stator assembly 16 and in Rotation offset.
  • the housing 14 has a pinch edge 39, which between the outer surface 40 of the rotor 21 or the magnetic ring 38 and a cylindrical End wall 41 of the second chamber 19 covers existing gap 42, so that splashing losses are minimized.
  • the cylindrical wall 22 between the stator assembly 16 and the rotor 21 is very thin, so that there is a very narrow iron-free gap and thus low magnetic circuit losses, with which the number of windings and / or the current strength can be minimized.
  • An elastic seal 43 is inserted between the housing 14 and the pump cover 28 and elastic by the connecting force between housing 14 and pump cover 28 deformed. Any connection type, e.g. B. a bayonet lock or welding can be provided.
  • Housing 14 and cover 18 and Pump cover 28 and rotor 21 can be made of plastic, advantageously polyphenylene sulfide, consist. To save the expensive high-quality polyphenylene sulfide the plug cover 18 can consist of a cheaper plastic.
  • Fig. 3 shows a side view of Fig. 2 with a detail from which the arrangement of the Ring channel 25, the separating section 26 and the wing-shaped conveying members 24 of the Rotor 21 and the two connecting pieces 27 can be seen.
  • Fig. 4 shows a complete stand package 16 with the individual sheets 46 and windings 47.
  • a plastic middle part 48 is pressed, into which several contact elements 49 are inserted, which have hooks 50 which are welded to winding ends 51. This results in cost-effective production.
  • a printed circuit board 52 is also placed on the middle part 48 and an electrical connection is made to the contact elements 49 by soldering.
  • the complete stand package 16 is held in the installed state by a plug cover attachment 53, which is supported on the printed circuit board 52 and loads it against contact surfaces 54 of the housing 14 (FIG. 2).
  • the air pump 8 can decouple structure-borne noise Have coupling ring 55 which is attached to the housing 14 and with a holder 56 is connected for mounting at an attachment point in the vehicle.
  • the coupling ring 55 by a shoulder 57 of the Plug cover 18 is loaded, so that the plug cover 18 and the housing 14 of the reaction force of the coupling ring 55 are exposed and thereby the plug cover 18th by means of snap-on clip attachments 58 on the housing 14 or housing recesses 59 supports and at the same time the chambers 15, 19 to the atmosphere by contacting the coupling ring 55 sealed to a housing wall 60 and the plug cover shoulder 57 are.
  • the housing 14 can be made of a high quality plastic and the plug cover 18 consist of an inferior plastic, the latter is subjected to deformation during assembly, but remains dimensionally stable Adapts housing 14.
  • the pin 20 can be molded around with the pump cover 28 and into the bore 29 of the housing 14 can be pressed in, with longitudinal ribs 61 being deformed in the bore 29 and the pin 20 are adapted.
