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 flap arranged in an exhaust gas recirculation passage, the intake passage and the exhaust gas recirculation passage opening into a common collection passage, and 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 intake flap and the exhaust flap are controlled such that the
- Exhaust flap opens starting from the first position linearly with a drive signal of the drive device. However, the intake flap initially remains in the first position and is closed only above a planned drive signal.
- the flaps of the known mixing valves have a distance which corresponds at least to the diameter of the larger of the flaps. This prevents a collision of the flaps.
- the different drives of the flaps require a large amount of space, which, however, is often not available.
- 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 structural complexity for driving the flaps can be kept particularly low according to another advantageous embodiment of the invention, when the drive device has a single electric motor and when the electric motor is connected via a respective adjusting means with the flaps.
- the mixing valve allows the complete replacement of two individual valves. Thanks to the invention, numerous components, such as housing, cover, sensors and plug connection for the electric motor are simply needed.
- the mixing valve according to the invention in addition to the space advantage also offers a major cost advantage.
- the electric motor may according to another advantageous embodiment of the invention have an electric motor with particularly small dimensions, if at least one of the actuating means has a gear transmission with multiple gears up.
- Such electric motors usually have a high speed.
- the gear transmission allows the translation of the high speed of the electric motor to the intended pivotal movement of the flaps.
- the sequence of movements of the flaps can be easily controlled according to another advantageous development of the invention. ern when a coupling is arranged between the one adjusting means and the flap.
- the coupling is structurally particularly simple according to another advantageous embodiment of the invention, when the clutch is a dog clutch with a backlash.
- the sequence of movements and the speed of movement of the flaps can be made particularly versatile according to another advantageous development of the invention, if at least one of the actuating means has a control cam for guiding a control part.
- the cam and the control part designed according to another advantageous embodiment of the invention structurally particularly simple when the control cam is arranged on the outer contour of a driven wheel and when the control part is connected to one of the flaps, rolling on the control cam role.
- the flap is resiliently biased with wheel against the outer contour.
- the combination of the drive of a flap by means of the control cam and the other flap by means of the gear transmission allows the particularly small dimensions of the mixing valve.
- the number of bearings can be kept particularly low according to another advantageous embodiment of the invention, when the cam having the wheel is arranged on a gear of the gear transmission. This contributes to a further reduction in the size of the mixing valve.
- the flowing in the intake passage and the exhaust gas recirculation passage gases can be mixed according to another advantageous embodiment of the invention as desired, if in one
- Fig. 1 shows an internal combustion engine with an inventive
- Fig. 3 schematically pivoting movements of valves of the
- FIG. 1 schematically shows an internal combustion engine 1 with an intake line 2 and with an exhaust gas line 3.
- the intake line 2 has an intake passage 4, via which air is drawn in from the environment.
- an exhaust gas recirculation passage 5 leads via a mixing valve 6 into the intake passage 2.
- the mixing valve 6 merges the intake passage 4 and the exhaust gas recirculation passage 5 to form a collecting passage 7.
- the collecting channel 7 leads directly to the internal combustion engine 1.
- a drive device 8 with an electric motor 9 enables an adjustment of the mixing valve 6.
- FIG. 2 shows the mixing valve 6 from FIG. 1 with the drive device 8.
- the drive device 8 is shown schematically.
- the mixing valve 6 has a arranged in the intake passage 4 pivotable flap 10 and arranged in the exhaust gas recirculation passage 5 pivotal flap 11.
- the arranged in the intake passage 4 flap 10 is slightly larger than the arranged in the exhaust gas recirculation passage 5 flap 11.
- the distance from pivot axes 12, 13 the flaps 10, 11 is about 80% of the diameter of the larger, arranged in the intake passage 4 flap 10th
- the flaps 10, 11 are driven by the single electric motor 9.
- the pivoting direction of the flaps 10, 11 extends in the same direction, as illustrated in the drawing with arrows.
- the drive device 8 has first, leading to the arranged in the intake passage 4 flap 10
- the arranged in the intake passage 4 flap 10 leading actuating means 14 have a gear transmission 16 with a plurality of gears 17 and a clutch 18.
- the clutch 18 has a backlash 19, by which the gears 17 can be driven without the flap 10 is moved.
- the arranged in the exhaust gas recirculation passage 5 flap 11 actuating means 15 have a control cam 20 for moving a control part 21.
- the control part 21 is connected via a lever 22 with the arranged in the exhaust gas recirculation passage 5 cap 11.
- the control cam 20 is arranged on the outer contour of a gear 23 driven by the gear wheel.
- the control part 21 is designed as a roll rolling on the outer contour.
- Both flaps 10, 11 are biased by spring elements, not shown, in the open position.
- the drive device 8 thus drives the flaps 10, 11 in the closing direction.
- FIG. 3 shows the opening angle Ot of the flaps 10, 11 over a range of movement of the toothed gear 16.
- the movement of the flap 10 arranged in the intake channel 4 is indicated by I and the movement of the flap 11 arranged in the exhaust gas recirculation channel 5 is indicated by II.
- the range of motion is shown in percentage. It can be seen here that in an initial state of 0% of the movement range, the flap 10 of the intake duct 4 is completely open, while the flap 11 of the exhaust gas recirculation duct 5 is completely closed. In a drive of the gear wheel drive 16 to 50% of the range of movement, both flaps 10, 11 are fully open. Subsequently, the flap 10 arranged in the intake passage 4 closes completely, while the flap 11 arranged in the exhaust gas recirculation passage 6 remains in the fully open position.

Abstract
L'invention concerne une soupape mélangeuse (6) d'un moteur à combustion interne (1) de véhicule automobile, dans laquelle la distance des axes de pivotement (12, 13) de deux clapets (10, 11) est plus petite que le diamètre du plus grand clapet (10). Les clapets (10, 11) sont en outre reliés à un unique dispositif d'entraînement (8). Ce dernier (8) assure un couplage exempt de collision des mouvements des clapets (10, 11). De ce fait, la soupape mélangeuse (6) est particulièrement compacte.
