- FIG. 1 we see the air supply circuit of the cylinders 100 of a turbocharged internal combustion engine for a motor vehicle.
- the air taken from the outside, passes through an air filter 101 and is compressed by the compressor 102 of the turbocharger which sends it into a double doser, object of the invention.
- the body 1 of the double doser has an inlet channel 2 through which the air coming from the compressor and two outlet channels 3 and 4 passes. It receives orders for the determination of the air between these two channels.
- a calculator 103 said ECU for Electronic control unit or electronic control unit.
- the burnt gases are directed towards the exhaust system and pass into the turbine 104 of the turbocharger, which takes a part of their residual energy to drive the corresponding compressor 102. These exhaust gases then pass through a filter particulate and / or catalyst 105 before being ejected from the vehicle.
- part of the exhaust gas is recycled, via a high-pressure valve 106 located upstream of the turbine 104, into the fuel circuit. intake downstream of the junction of the two exit lanes 3 and 4.
- the body 1 of a double doser with the input channel 2 and the two output channels 3 and 4.
- the first channel 3 is intended to be connected to a cooler 5 while the second channel 4 is intended to bypass this cooler to directly reach the intake pipes.
- Each of the two channels 3 and 4 is dosed by a flap movable about an axis which is mounted on an axle support, 7 for the first channel and 8 for the second.
- the dosage on each channel is effected by the rotation of the flap, which more or less obstructs the flow of air or gas that passes through the corresponding channel.
- the body 1 also comprises a support 6 for the electric motor for actuating the two flaps, to which they are connected by an appropriate kinematics.
- FIG. 4 shows a flap 10 and its control device, in a version intended for a cooled track 3.
- the flap 10 is mounted on its axis 1 1, the lower end of which is intended to rotate in the axle support 7 doser.
- the flap is thus rotatable relative to the body 1.
- the upper end of the axis 1 meanwhile, carries a first upper plate 12 to which it is fixed rigidly so that a rotation of this upper plate triggers a rotation of the same magnitude of the flap 10.
- On the axis 1 1 is also mounted a lower plate 13 which is free to rotate about the axis and which, therefore, n ' is not driven in case of rotation of the upper platen 12.
- the axis 1 1 carries a toothed wheel 14, free to rotate about said axis, the latter allowing the driving of one or the other or both turntables, according to a principle that will be explained later.
- the toothed wheel 14 is driven, in one direction or the other, by a pinion mounted on the output shaft of the electric motor controlled by the ECU 1 03.
- This gear wheel is the actuating member of the two plates and, in fine, positioning the shutter 10.
- each plate here comprises a notch, referenced respectively 121 and 131, which forms a housing in which is embedded the corresponding end of the return spring 15, and which takes the force exerted by the spring.
- the upper plates 12 and lower 13 will now be described in relation to Figures 4 to 6. While the upper plate 12 has a slot 122, mortise type, in which is inserted a pin carried by the axis 1 1 to secure it with this axis, the bottom plate 13 comprises a tubular bearing 132 in which the axis 1 1 can rotate freely. This ensures both the attachment of the upper plate 12 with the axis and the free rotation of the lower plate 13 relative to this axis.
- Each of these two plates further comprises two radially extending protrusions, so as to form both an upper short stop 123, respectively a lower short stop 133, and an upper long stop 124, respectively a lower short stop 134, which are intended to constitute limits to the rotation of these plates vis-à-vis the surrounding parts.
- the long stops 124 and 134 are intended to limit the rotation relative to the body 1 of the double doser, cooperating with fixed stops positioned on this body, while the short stops serve as a support for driving the plates and / or the compression of the spring 15 under the action of the toothed wheel 14.
- the angular position of these stops, both short and long is defined to adapt the position of the flap to the operating case considered for the engine.
- the toothed wheel 14 is in the form of a disc having teeth over most of the circumference of its outer face 141 so as to be rotatable by the pinion of the actuating motor. double doser. At its center it comprises a cylindrical tube 142, extending axially, which forms a bearing for the axis 1 1 of the metering flap flow passing through the considered channel. Finally to his periphery, the toothed wheel comprises a drive pin 143 which extends axially and which has the function of cooperating with the short stops upper 123 and lower 133 of the two plates 12 and 13 of the first channel. Its radial distance to the axis 1 1 is therefore substantially equal to that of the short stops of the two plates for their training.
- the second channel corresponding here to the uncooled channel 4, comprises a control device similar to that described, except that it comprises only one upper plate, said second upper plate 22, and no lower plate.
- the finger 243 of the second toothed wheel 24 then cooperates only with an upper short stop 223.
- the return spring 25 of the second track is carried at its ends, on the one hand, by a notch positioned on the upper platen and, secondly, by a fixed stop which, it is positioned on the body of the double doser.
- These elements are shown schematically in Figures 10 to 16. All other elements are similar to those of the first channel. It is also, of course, that the first channel can be chosen as the uncooled track, which would then include two plates, the second channel then being the cooled track, which would then include only one plate.
- FIGS. 8 and 9 the relative evolution of the positioning of the two flaps, under the action of a control of the actuator motor of the double dispenser, and of the drive kinematics of the two toothed wheels are shown. and 24.
- the pinion of the actuating motor meshes directly with one of the two toothed wheels, the second meshing on the first and thus rotating in an opposite direction.
- This first mode could equally well be achieved with a pinion meshing with the two toothed wheels, which would then rotate in the same direction, the driving dynamics of the second flap being adapted accordingly.
- the rest position that is to say that take the first plates 12 and 13 of the first channel 3, and the second upper plate 22 of the second channel 4, in the case of an absence or loss of drive by the actuating motor, corresponds to the ordinate axis.
- This is the position, marked "0" occupied by the flaps under the action of the springs 15 and 25 of each of the channels.
- the flap 10 of the first track 3 is open, while the flap of the second channel 4 is closed.
- the actuating motor is capable of driving the gears in a rotation of magnitude - in one direction and a rotation of magnitude 2 in the other direction.
- a rotation of the toothed wheels of the angle -a causes the shutter of the first lane to close while that of the second lane remains closed.
- a positive rotation of the toothed wheels by an angle represented by the branch B, causes both a closure of the shutter of the first track and an opening of the shutter of the second track.
- the continuation of the rotation of a second angle represented by the branch C, causes closure of the flap of the second path, that of the first path remaining closed.
- Branch A corresponds to a dosage of the fluid that passes through the first lane
- the temperature obtained remains constant and equal to that obtained at the outlet of the cooler since all the fluid passes through this cooled path.
- the branch B corresponds to a regulation of the temperature of the fluid, without dosage of its volume.
- the opening and closing kinematics of the two flaps are represented here, without this being imperative, as compensating each other, which makes it possible to obtain a constant output flow for all the positions of the branch B.
- the branch C corresponds to a flow rate determination on the only second channel and therefore a flow rate determination on the fluid at the uncooled temperature.
- FIG. 11 represents the rest position
- FIGS. 10, 12 and 13 correspond to at rotations respectively of -a, + a and + 2a.
- the position of the fingers 143 and 243 of the two gears in the rest position is recalled by a dotted line.
- the toothed wheel 14 of the first track is represented twice, with the indication of the position of its finger 143 both at the level of the upper plate 12 and at the level of the lower plate 13.
- FIG. 10 shows the position of the various elements of the double doser in the extreme configuration of the branch A, after a rotation of the actuating motor which has brought the flap 10 of the first channel 3 in the closed position (rotation of the actuating motor by an angle -a, taken here equal to -83 °).
- the gears 14 and 24 of the two lanes have rotated in opposite directions because, by choice of construction, their teeth mesh with one another and only one of them meshes with the gear of the motor. actuation.
- the fingers 143 and 243 of these gears turned, respectively 83 ° for the first and -83 ° for the second, with reference to the direction of rotation of the clockwise.
- the upper plate 22 On the second track 4, the upper plate 22 has not rotated, it being blocked by the cooperation of its second long stop 224 with a second fixed upper stop 225 positioned on the body 1 of the double doser.
- the flap of the second channel 4 remains closed for all positions of the actuating motor that correspond to the points of the branch A.
- a rotation of the actuating motor causes an equivalent rotation of the upper plate 12 which is driven by the rotation of the first finger 143, associated with a closing of said first channel.
- Parallel to the rotation of the first gearwheel 14 has not changed the orientation of the lower plate 13, the latter being locked in rotation by the cooperation of its long stop 134 with a lower fixed stop 135 which is positioned on the body 1 of the double doser.
- the rotation of the upper plate 12 and the non-rotation of the lower plate 13 allows the compression of the spring 15 of the first channel by creating an offset of 83 °, with respect to its offset in the rest position, between the circumferential orientation both ends of the spring 15. This compression allows the automatic return of the first upper plate to the rest position when the actuating motor will return its angle -a to 0 °.
- Figure 1 1 the two upper and lower plates of the first channel and the upper plate of the second channel are in their rest position, which corresponds to the meeting point of the branches A and B.
- the upper plate 22 of the second channel and the bottom plate 13 of the first channel are in contact with their fixed stops, respectively 225 and 135, under the action of the only preload given to the springs 15 and 25 of these two channels, in order to guarantee the automatic positioning of the shutters. in their rest position, especially in case of failure of the actuating motor.
- the first channel 3 is fully open, allowing the intake flow to pass to the cooled path and the second channel 4 is closed, which makes it possible to supply the cylinders, for safety reasons, with a fluid which is the most cooled possible.
- Figure 12 shows the position of the various elements in the extreme configuration of the branch B, at the point of intersection with the branch C, ie after a rotation of the motor actuation which gradually brought the flap 10 of the first channel 3 in the closed position (rotation of the actuating motor by an angle + a, taken here equal to 83 °) and the flap of the second way gradually in the open position .
- the closed position of the first flap 10 is 166 ° to that obtained at the end of the branch A, or substantially after a complete reversal of the flap about its axis January 1.
- the fingers 143 and 243 of the toothed wheels turned, accordingly of -83 ° for one and + 83 ° for the other.
- the first upper plate 12 has turned -83 ° under the action of the spring 15 of the corresponding channel until its upper long stop 124 abuts against the first corresponding upper fixed stop 125.
- the first finger 143 has driven the lower plate 13 in a rotation of -83 °, this which has the effect of not modifying the compression level of the return spring 15, leaving it at its preloading level to drive the upper plate 12.
- the finger 243 of the second gear 24 has driven the second upper plate 22 in a rotation of + 83 °, by compressing the second spring 25 to allow the device to return to its rest position in case of failure of the actuating motor.
- the closure of the first flap 10 simultaneously with the closure of the second flap 20 makes it possible to maintain a substantially constant cross section for the metering device as a whole and to regulate the temperature of the intake fluid, at constant engine load, as appears on FIG. figure 9.
- FIG. 13 shows the position of the various elements in the extreme configuration of the branch C, ie after a second rotation of the actuating motor by an angle + a, which progressively led the flap of the second track 4 into position closed, the flap 10 of the first channel 3 remaining in the closed position.
- the closed position of the second flap is substantially 180 ° from the closed position obtained at the end of the branch A.
- the fingers 143 and 243 of these gears have continued their rotation by a second value a.
- the first upper plate 12 has been blocked by the cooperation of its upper long stop 124 against the first upper fixed stop 125 while the lower plate 13 has rotated by an angle to put the first spring Under stress.
- the upper plate 22 of the second channel has continued its rotation, driving the corresponding flap and assuring a dosing of the fluid flow on the second channel 4, at constant temperature, since the first channel remains constantly closed.
- the rotation of the upper plate 22 also has the effect of compressing the second spring 25 in a complementary manner. compression of the two springs 15 and 25 is then added to give the devices the possibility of returning to its rest position.
- FIGS. 14 to 16 in another embodiment, the kinematics set up to produce the diagrams of FIGS. 8 and 9 are seen.
- These figures describe the movements of the elements during the branches A, B and C, with a dashed recall of the position of a platen when it corresponds to the rest position of the corresponding flap.
- the plates 12, 13 and 22 are illustrated by rectangles, movable.
- the state of the flaps corresponding to the positioning of the plates is indicated by an "O" for open and an "F” for closed in said rectangles.
- the displacement of the plates along the branches A, B and C is also represented by two positions interconnected by an arrow.
- FIG. 14 shows the unwinding on the branch A, where the actuating motor passes from 0 ° to -a, that is to say that of a progressive closure of the flap 10 of the first path 3, starting from its rest position which corresponds to a full open position. It also corresponds to that of a metering of the intake fluid on the only first channel 3, the second channel 4 remaining closed by the second flap 20.
- the finger 143 of the first gear 14 drives the upper plate 12 of the first channel by compressing the first spring 15.
- the first upper plate 12 is shown clearly in its initial position, full open referenced O, and in a closed position, greyed and referenced F.
- the lower plate 13 is held in place by the lower fixed stop 135 of the metering body which blocks it in rotation and allows compression of the first spring 15.
- the second way is not affected during this branch A, the second spring 25 being in its prestressing position and the second upper plate 22 being in its rest position, pressed against the second upper fixed stop 225 under the action of said second spring 25.
- Figure 15 shows the position of the various elements on the branch B, which corresponds to a so-called proportional dosage of the intake fluid. All the points of the branch B correspond in fact to a dosage in variable proportions of the fluid passing in the two channels.
- the first spring 15 remains, in this branch B, in a prestressing position as long as the first upper plate 12 does not come into contact with the first upper fixed stop 125, and drives the first upper plate 12.
- the second finger 243 progressively opens the second lane 4 by pushing the second upper plate 22 and subsequently the second louver 20.
- second spring 25 compresses progressively, unlike the first spring which remains preloaded along the branch B.
- the first flap 10 is completely closed and the second flap 20 completely open.
- the kinematics of the two flaps is, a priori, designed so as to maintain a constant flow rate for all of the two channels 3 and 4 for all the points of the branch B.
- FIG. 16 shows the dosing on the second path 4 by the displacement of the second upper platen 22 under the action of the second toothed wheel 24. More precisely, the finger 243 of the second toothed wheel 24 drives the short stop 223 of FIG. the second upper plate and subsequently the shutter of the second channel which closes gradually.
- the first upper plate 12 remains in abutment against the first upper fixed stop 125 and the compression of the first spring 15 increases, because the first lower plate 13 is rotated by the first finger 143 whereas the first upper plate 12 is in abutment. The compression of the two springs 15, 25 is added.
- the drive motor does not drive the gears directly, but it acts by means of an actuator which either rotates the planet gear carrier which meshes with the gears, or rotation, in the opposite direction of the previous one, the toothed wheel of one of the two lanes, here the second lane.
- the shutters are driven, for the first track by the shaft of the carrier, and for the second track, by the gear wheel on which the actuator acts directly.
- the elements of the second mode that have the same function as in the first mode have the same reference number and are not described again.
- Figure 17 is a schematic perspective view of the device while Figures 18 to 21 are views unfolded on a plane of the same device.
- the device is described in the rest position, that is to say the one where the shutter 1 0 of the first channel is open and that of the second channel is closed.
- the positioning is then analogous to that of FIG. 11 in the first embodiment, that is to say at the transition between the branches A and B.
- FIG. 18 corresponds to a rotation of the drive motor of an angle -a
- Figures 20 and 21 correspond to rotations of the drive motor angles respectively + a and + 2a.
- the first gear 14 operates as the outer ring of an epicyclic gear while the second gear 24 operates as the sun gear of the train.
- a satellite 33, linked in rotation to a carrier 34, is housed between these two gears and ensures their combined drive.
- a driver 30, actuated by the actuating motor (not shown), is movable in rotation about the axis of the epicyclic gear and has a driving pin 31, first of all the finger 243 of the second gear wheel and secondly a third finger 343 carried by the planet carrier 34. It is represented in FIG. 17, in solid lines and in dashed lines, in the two positions in which it engages respectively on the finger 243 of the second toothed wheel. and on that 343 of the planet carrier.
- a return spring 35 tends to push the finger 343 of the planet carrier 34 of the finger 143 of the first toothed wheel and to return the planet carrier to its rest position corresponding to the state of prestressing of the spring.
- the body 1 of the double metering device comprises a number of fixed stops, which will be detailed below, against which the fingers of the gear wheels and that of the planet carrier come to rest to operate the epicyclic train and let two of its elements while the third is stationary.
- the actuator 30 In the position -a of the actuating motor, which is illustrated in FIG. 18 and which corresponds to the end of the branch A, the actuator 30 is in a full retracted position, which is associated with a closed full position. of the flap 1 0 of the first lane 3.
- the second gearwheel 24 remains in a position where the flap of the second lane 4 is also closed; this position is defined by placing on a first fixed stop 246 of the second channel, which is formed on the body 1 of the double doser. More specifically, along the branch A, the finger 243 of the second gear 24 remains in contact with this first fixed stop of the second path 246 and the second flap 20 therefore remains closed.
- the flap 10 of the first channel follows, on the other hand, the movement of the planet carrier 34 and gradually closes along this branch A, passing from the position 0 ° to -a, thus ensuring the dosing on the only first channel 3
- the first toothed wheel 14 positioned as the ring gear of the epicyclic gear train, it is rotated by that 33 of the planet carrier 34 since the sun gear 24 is blocked by the first fixed stop 246 of the second track. It encounters no stop along the branch A.
- the spring 35 undergoes against a first compression, because the planet carrier 34 rotates slower than does the crown 14 of the epicyclic gear; this compression ensures the possibility of return of the carrier 34 to the rest position when the driver 30 is released or is pushed to the 0 ° position.
- the second finger 243 In the rest position, illustrated in FIG. 19 and corresponding to a 0 ° setting of the rotation of the motor of the actuator, the second finger 243 is, as already mentioned, in abutment against its first fixed stop 246 while the pin 31 of the actuator 30 is in contact with the second finger 243.
- the third finger 343 is also in contact with the pin 31, being biased towards this position under the action of the return spring 35.
- the position of the actuator 30 corresponds to a position of the satellite carrier 34 in which the flap 10 of the first channel 3 is open.
- the second channel 4 is still in the closed position and the finger 143 of the first toothed wheel is in abutment against its fixed stop 146.
- the finger 143 of the first gear remains in abutment against its fixed stop 146.
- the extension of the actuator 30 pushes the second gear 24, thus opening the second path; parallel, under the action of the second gear which acts as a sun gear, the planet carrier 34 is rotated which ensures the closure of the flap 10 of the first path. In this way, the desired proportional dosage and the constancy of the flow rate of the inlet fluid are obtained on all the two channels.
- the actuator 30 has moved sufficiently for the planet carrier 34, under the action of the return spring 35, to come on a fixed stop of the planet carrier 346, which corresponds to a closed full position of the first track 3.
- the second gear 24 is in an intermediate position between its first second track stop 246 and a second second track stop 247 explained later, which corresponds to the open full position the second part 20.
- the branch C corresponds to an even larger extension of the actuator 30, the final position of which is illustrated in FIG. 21.
- the planet carrier 34 remains blocked by its fixed stop 346 and the planetary gear train generates a simultaneous rotation of the two wheels. toothed.
- the actuator 30 completely pushes the second gearwheel 24 by its lug 31 and progressively closes the flap of the second lane 4, while the first lane 3 remains closed, thus ensuring the dosing of the intake fluid on the only second lane.
- This progression continues until the second finger 243 encounters the second second channel stop 247, which is formed in the body 1 of the dual metering device.
- the position of this second stop corresponding to the closed full position of the second flap 20, thus avoiding that it exceeds this position of full closure.
- this second embodiment reproduces the same diagram of opening and closing of the flaps of the two channels 3 and 4, as the first mode, as illustrated in FIGS. 8 and 9.
- the kinematic disengages one of the flaps 10, 20 relative to each other to ensure the dosing function on one of the channels, the flap of the other path remaining fixed. That being said, according to another aspect of the invention, the dual metering device according to the invention can also operate without kinematic disengaging.
- the body 1 of the dispenser comprises an internal housing 404, separated into a first stage 500 for the first circulation channel 3, comprising said first flap 10, and a second stage 502 for said first flap second traffic lane 4 comprising said second flap 20.
- said first and second flaps 10, 20 comprise at least one closure portion 414, arranged in a plane inclined with respect to said cylindrical housing 404 and cooperating with the side wall 405 of said housing by a peripheral generator so as to provide a sealing contact between the flaps 10, 20 and the body 1 in at least one angular position.
- Said proportioner further comprises a control rod 415, driven by said kinematics and connected to the first and second flaps 10, 20,
- the body 1 of the dispenser is provided with an inner housing 404 which is cylindrical with axis A and circular section and which is delimited by a side wall 405.
- the inner housing 404 can be likened to a bore.
- an inlet 406 and an outlet 407 forming a path for the fluid to flow through the housing of the valve.
- These inputs 406 and 407 are aligned with each other. They have here a longitudinal axis X perpendicularly intersecting the axis A of the housing 404, and have identical diameters. They extend beyond the side wall 405 of the housing by conduits, not shown, integrated into the body 1 and for connection with the circuit equipped with said metering device.
- the stages 500, 502 are separated by a partition 409, provided with an orifice 413. At one and / or the other of its ends, there is a transverse cover 410 extending by a tip 41 1 with an axial hole. 412. The orifice 413 of the partition 409 and / or the axial hole of the transverse lids 410 are traversed by said control rod 415.
- the inclined portion 414 is shaped as an elliptical shutter 416 disposed in a plane inclined relative to the axis A of the circular cylindrical housing 404 and centered on said axis A, so that its peripheral edge 417 is in constant contact with the side wall.
- This peripheral edge 417 thus constitutes a generatrix G always in sealing contact with the side wall 405 of the housing.
- inclined is meant strictly between 0 ° and 90 °.
- Shutter here means a part having two surfaces inclined relative to the axis A and connected by the peripheral edge 417. The said inclined surfaces are optionally parallel to each other. The piece has a small thickness, namely a distance between said inclined surfaces much smaller than the diameter of the body, in particular ten times lower. This is, for example, a disk.
- the flap 416 has an elliptical shape of greater axis greater than the diameter of the circular housing 404 and minor axis substantially less than the diameter of the circular housing 404.
- the diameter of the circular housing 404 is also greater than the identical diameters of the inputs 406. and outputs 407 of fluid.
- the connecting rod 415 is arranged along the axis A of the housing, so as to be centered on the inclined disk, with the angle B between the inclined plane of the disk and the axis A here equal to 45 °.
- the major axis of the disc 416 is therefore substantially equal to the housing diameter multiplied by V2.
- This contact can be defined as being a cylinder / cylinder contact between the wall 405 of circular section of the housing 404 and the generator G corresponding to the peripheral edge 417 of the inclined disc 416 and which is circular in projection on a plane perpendicular to the axis of shutter rotation.
- the small axis of the flap 416 may be substantially greater than the diameter of the inputs 406 and 407 fluid outlets.
- the rod 415 is associated with the disk 416, by assembly or overmolding, or it is formed with the disk, so as to have a one-piece sealing means.
- the disc 416 may be plastic and the rod 415 metal or vice versa, or both may be plastic or metal according to the monobloc or composite embodiment chosen.
- the axial hole 412 of the nozzle 41 1 may be provided with a guide bearing 418.
- Said control rod 41 6 may be continuous and through said housing.
- the inclined disk 416 isolates the inlet 406 from the outlet 407, preventing the flow of fluid through the valve 1.
- the peripheral edge 417 of the inclined disc 416 cooperates with sealing and completely with the side wall 405 of the cylindrical housing 404, in the manner of a partition separating the housing into two separate internal chambers and sealed, each facing one of the inlet channels 406 and 407 of the fluid passage.
- This angular position of the inclined disk 416 corresponds to a closure of the illustrated traffic lane.
- the drive device When the drive device is biased, it causes rotation of the control rod 415 and flaps 10, 20 at the desired angle corresponding to a given flow rate of fl uid e through the use channel.
- the peripheral edge 417 is no longer in full contact with the side wall 405 of the housing, but only partially since opposite portions of the edge 417 are opposite the circular inlets and outlets 406 and 407. This erased angular position of the disc allows the passage of fluid between the inlet 406 and the outlet 407, at one and / or the other of the stages, via the inner sealed housing 404 of the body.
- the dispenser can be operated in both directions from an original position as the dispenser can be operated for more than 360 °.
- Such a van does not therefore ensure sealing in both directions of closure by the adaptation of the inclined disc in the circular housing (cylinder-cylinder contact), which disc, by its symmetry, can be mounted indifferently in both meaning without coding in the body of the valve.
- the edge of the disk moves linearly on the cylindrical wall, this makes it possible to prevent clogging between the disk and the wall and to ensure self-cleaning of the valve.
- said first and second flaps 1 0, 20 have between them an angular offset with respect to said control rod 415 and / or said traffic lanes 3, 4 having between them an offset angularly relative to said control rod 415, the angular offset of the flaps 10, 20 being related to the angular offset of said traffic lanes 3, 4.
- the circulation lanes 3, 4 are oriented in the same direction and the first and second flaps 10, 20 are offset by 60 °.
- the inlet and outlet ports 406, 407 are aligned in the same direction from one floor to another.
- Figures 26 and 27 to 30 help to better understand how the successive positions occupied by the flaps 10, 20 make it possible to achieve the desired control law.
- FIG. 26 illustrates different points of passage of the flaps, with respect to the inlet and outlet orifices 406, 407 of the corresponding channels, during their rotation about the axis A.
- FIGS. 27a to 30a show the position of the inclined disc 416 of the first flap 10, respectively of the second flap 20, depending on the height (mm) of the side wall 405 of the housing, which wall is developed from -180 ° to + 180 ° to be represented in plan.
- the trace 504, 506 of the flaps 10, 20 on the side wall 405 is illustrated by a double wavy line which thus has a sinusoidal shape.
- the inlet ports 406 correspond to a circle, centered on the graphs.
- the outlets 407 each correspond to two semicircle, being on the other side of the graphics. It can be seen first of all that, regardless of their angular position, said traces 504, 506 are well offset by 60 ° from each other between each of FIGS. 27a and 27b, 28a and 28b, 29a and 29b, as well as 30a and 30b.
- the first flap 10 is open, the trace 504 crossing the circles of the orifices 406, 407 of the first lane, while the second louver is still closed, its lane 506 not intersecting the circles of the orifices 406, 407 of the second lane.
- a dosage was therefore made on the first channel, only the first flap 10 passing from a closed position, illustrated in FIG. 27a, to a fully open position, illustrated in FIG. 28a, while the second flap 20 even if it is mobile, continues to close the second way.
- FIGS. 30a and 30b the two flaps 10, 20 are both closed again, their trace 504, 506 not crossing the circles of the orifices 406, 407.
- An assay was thus made on the second path, only the second flap 20 passing from a fully open position, illustrated in Figure 29b, to a closed position, illustrated in Figure 30b, while the first flap 10, although movable, continues to close the second way.
- the flaps 10, 20 From the positions illustrated in Figures 27a, 27b to the positions illustrated in Figures 30a, 30b, the flaps 10, 20 have rotated 180 °. They can perform the same cycle in the opposite direction or continue their rotation until reaching the initial position of Figures 27a, 27b.
- Said rod can be connected directly to the driving motor.
- the kinematics then consists of the drive shaft.
- the double doser makes it possible, by the progressive rotation of a single actuating motor, to dose the admission fluid on the only first path (branch A according to the modes of clutch embodiment), the second channel being closed, on the only second channel (branch C according to the clutch embodiments), the first channel being closed or simultaneously simultaneously with the two channels (branch B according to the embodiments clutch) by dosing the distribution between the two lanes.
- the dual metering device makes it possible to regulate the temperature of the intake fluid.
- calibrating the opening and closing curve of the flaps as a function of the rotation angle of the actuating motor, it is possible to maintain a constant overall flow rate during this proportional dosing and to act in this branch only on the final temperature of the fluid.
