Definitions

  • the invention relates to a mixing valve of an internal combustion engine of a motor vehicle having a flap arranged in an intake passage and a valve disposed in an exhaust passage flap, with rotatable, the valves holding waves, the intake passage and the exhaust passage into a common collection channel, and with a drive means for driving the flaps.
  • Such mixing valves are often used in exhaust gas recirculation systems of internal combustion engines of modern motor vehicles and are known from practice.
  • the movements of the flap of the intake passage and the flap of the exhaust passage are controlled such that the flap of the exhaust passage opens from the first position linearly with a drive signal of the drive means.
  • the flap of the intake passage initially remains in the first position and is closed only above a designated drive signal.
  • the flap of the exhaust passage remains in the open position.
  • the invention is based on the problem to design a mixing valve of the type mentioned so that it has a very small space.
  • the flaps can be particularly close to each other order.
  • the position of the driver is determined how the flaps are controlled in response to the movement of the drive pinion. Since the drivers of the control discs and the drive pinion can be freely positioned, almost any movement can be generated with a single drive. As a result, the space of the mixing valve according to the invention is kept particularly low.
  • the control discs and the drive pinions are sandwiched over one another, which contributes to the compact construction of the mixing valve.
  • the pivotal movement of the flaps can be easily limited according to another advantageous embodiment of the invention, when a shaft bearing housing has stops for supporting the arranged on the control discs driver.
  • a movement of the flaps in both directions can be according to another advantageous embodiment of the invention easily avoided if at least one of the control discs is biased by a spring element in the basic position. In conjunction with the coupling of the drive pinion via the intermediate gear, it is sufficient if only one of the control discs is biased in the normal position.
  • the drive pinions are formed as part gears with a exclusively over 180 ° extending sprocket.
  • FIG. 1 schematically shows an internal combustion engine 1 with an intake passage 2 and with an exhaust pipe 3.
  • the intake passage 2 has an intake passage 4, is sucked through the air from the environment.
  • an exhaust passage 5 via a mixing valve 6 into the intake passage 2.
  • the mixing valve 6 performs the intake passage 4 and the exhaust passage 5 to a collecting channel 7 together.
  • the collecting channel 7 leads directly to the internal combustion engine 1.
  • a drive device 8 with an electric servomotor 9 allows an adjustment of the mixing valve. 6
  • FIG. 2 shows a sectional view of the mixing valve 6 FIG. 1 ,
  • the intake passage 4 and in the exhaust passage 5 are each a flap 10, 11 mounted on pivotal shafts 12, 13.
  • the exhaust passage 5 is arranged at right angles to the intake passage 4.
  • the servomotor 9 of the drive device 8 is arranged in the corner region between the intake duct 4 and the exhaust duct 5.
  • the shafts 12, 13 and thus also the flaps 10, 11 are driven.
  • the Figure 3a and 3b show from two perspectives the mixing valve 6 in a plan view of the drive means 8.
  • the mixing valve 6 has an open housing 14 shown with a plane open towards the recess 15 for receiving the servomotor 9.
  • On the shafts 12, 13 are respectively control discs 16, 17th arranged rotationally fixed and drive pinion 18, 19 rotatably mounted.
  • the drive pinions 18, 19 are connected to a common pinion 21 in engagement.
  • the servomotor 9 drives an intermediate gear 20 connected to the pinion 21.
  • the drive pinions 18, 19 have on their the control discs 16, 17 facing sides in each case a driver 22, 23, with which they protrude into a range of movement of a arranged on the control discs 16, 17 driver 24, 25.
  • Spring elements 30, 31 bias the control discs 16, 17 in a basic position in which the intake passage 4 is opened and the exhaust passage 5 is closed.
  • FIG. 4 shows for clarity the individual components of the drive device in an exploded view.
  • the flaps 10, 11 are fastened to the shafts 12, 13 by means of screws 33, 33 '.
  • the shafts 12, 13 have bushings 34, 34 'for mounting in the housing 14.
  • a cover 37 closes in the mounted state, the housing 14.
  • the arranged on the shaft 12 of the flap 10 of the output channel 4 driver 24 is connected via a further spring element 36 with the drive pinion 18 is connected.
  • a second, mounted on this shaft 12 driver 38 acts with in FIG. 5 shown stops 26, 27 of the housing together.
  • a structural unit of intermediate gear 20 and pinion 21 is rotatably mounted on a bearing shaft 39 fixed in the housing 14.
  • FIG. 5 shows a plan view of the housing 14. It can be seen that the housing 14 stops 26-29 for support of the drivers 24, 25 of the control discs 16, 17 has.
  • the housing 14 has, in addition to the stops 28, 29 for supporting the driver 25 of the control disk 17 of the flap 11 of the exhaust passage 5, a recess 32 for supporting the spring element 31st
