Definitions

  • the invention relates to a throttle valve unit with a housing which has a connecting piece which receives a shaft and a throttle valve associated therewith.
  • the throttle valve unit is particularly suitable for use in an internal combustion engine.
  • a throttle valve assembly which is used to adjust the power of an internal combustion engine and which is arranged between the outlet of an air filter and an inlet of an intake module of an internal combustion engine.
  • the throttle valve neck has a housing which has a neck which receives a shaft and a throttle valve associated therewith.
  • the throttle valve connector can be fastened to the outlet end of the air filter and to the inlet inlet of a suction module via fastening devices.
  • the object of the invention is to develop the known throttle valve unit so that it is simpler and can be used cost-effectively for various applications.
  • the throttle valve unit has a fastening device by means of which the throttle valve unit can be arranged on a suction module in such a way that the socket of the housing of the throttle valve unit is radially closed in a side recess of a suction module in the area of a throttle valve tube piece this is introduced.
  • the lateral recess is provided in the area of the throttle valve tube piece. It is designed radially and axially without completely interrupting the pipe section or the housing surrounding it, that is to say forming its end.
  • the throttle unit thus makes it possible in a simple manner to provide identical fastening devices for different applications with, for example, different diameters of the throttle valve tube piece and the connecting piece. This then makes it possible that the throttle valve only has to be extensively tested for use with a model by the manufacturer of the internal combustion engine and this can then be omitted for applications for other models.
  • the throttle valve unit can be easily arranged in an intake module. Furthermore, in particular with an increasing nozzle cross section, significantly less material is required than in the case of the conventional throttle valve connectors, which are flanged onto an inlet-side end of the intake module. This is particularly advantageous if the housing is made of plastic in an advantageous embodiment, since a more precise manufacture is easily possible because of the less required mass of plastic.
  • FIG. 1 shows a throttle valve unit and an intake module
  • FIG. 2 shows the throttle valve unit according to FIG. 1 in a second embodiment
  • FIG. 3 shows the throttle valve unit according to FIG. 1 inserted into an intake module according to FIG. 1.
  • An intake module 1 (FIG. 1) has a collector 2 and intake pipes 3 to 5, which lead to inlet channels, not shown Internal combustion engine are performed.
  • the intake module 1 further comprises a throttle valve tube piece 6, which is connected directly or indirectly to an air filter at its inlet end.
  • the throttle valve pipe section 6 has a recess which is designed radially and axially without completely interrupting the pipe section or the housing surrounding it. Furthermore, a lateral flange 9 is provided adjacent to the recess 8 and is used to fasten a throttle valve unit.
  • the throttle valve unit 11 has a housing which comprises a cover 13 and a lower housing part 15.
  • the lower housing part preferably comprises a connecting piece 17 which receives a shaft 19 and a throttle valve 21 associated therewith.
  • the nozzle is preferably only 1 to 5 cm wide in the axial direction. This saves mass accordingly, which is of particular advantage for the most precise possible production from plastic.
  • a bearing receptacle 23 is provided on the side of the throttle valve 21 that faces away from the cover 13, which is cone-shaped, preferably frustoconical.
  • the housing also includes a receptacle 25 for an actuator of the throttle valve 21, which is preferably designed as an electric motor with a corresponding gear.
  • the lower housing part 15 preferably also has a plug 27, which is designed to receive a corresponding mating plug and thus serves to connect the electrical supply and signal lines of the actuator 25 or a sensor (not shown) to a central control unit.
  • a fastening device provided which is designed as a lateral flange 29 of the throttle valve unit.
  • a groove 33 is provided coaxially to the throttle valve tube piece and thus to the free tube cross section of the connector 17, which receives an O-ring 35.
  • the throttle valve unit is fastened to the intake module by means of the flange 29 of the throttle valve unit and the flange 9 of the intake module 1, preferably by means of screws 37, 39.
  • the connector 17 is introduced into the lateral recess 8 of the intake module in the region of the throttle valve tube piece 6 radially to the latter.
  • the throttle valve can thus be used as a simple insert in the intake module, which makes it particularly suitable for highly integrated module solutions.
  • an overall extremely compact design of the intake module, including the throttle valve is made possible, which is particularly advantageous when there is often little space available.
  • the throttle valve can be attached to the intake module in a particularly simple and reliable manner.
  • the O-ring 35 which is introduced into the groove 33 of the connector 17, ensures that no leakage currents occur in the throttle valve tube section 6 when the intake module 1 is operating.
  • An O-ring is a simple and cheaply available ' standard part.
  • the peg-shaped, in particular frustoconical, outer contour of the bearing receptacle 23 can furthermore achieve a particularly reliable and precise fixing of the throttle valve unit 11 in the intake module 1 and at the same time ensure that the shaft 19 of the throttle valve 21 is very well supported.
  • the housing of the throttle valve unit 11 is preferably made of plastic. On the one hand, this enables cost-effective production and, on the other hand, "a weight saving compared to a structure made of metal.
  • the compact design of the connector 17 also ensures that the throttle valve functions properly in the entire temperature range in which the
  • FIG. 2 shows the throttle valve unit, which differs from that according to FIG. 1 only by a seal of a different design.
  • a groove 31 is provided along the outer contour of the connector 17, which receives a seal.
