Detailed description of the invention

With reference to Fig. 1 it can be seen that be used for the air supply loop to cylinder 100 of the turbocharging internal-combustion engines of motor vehicles. It is passed in air filter 101 from extraneous air, and is then compressed by the compressor 102 of turbocharger, this turbine Air is sent in the double throttle device of present subject matter by supercharger.The body 1 of this double throttle device have access road 2 with And two exit passageways 3 and 4, the air from compressor passes through via this access road 2.It is from computer 103 (referred to as electronics Control unit (ECU)) receive the order for controlling the air between said two passage.These orders are with flashboard displacement Form performs, flashboard more or less closing passage 3 He under electricity actuates the effect of motor (not shown) and appropriate exercise system 4, described electricity actuates motor and kinematics system is incorporated in the body of double throttle device.Heat exchanger or cooler 5 are arranged on it In on a passage, referred to as cooling duct 3, and another passage, referred to as bypass passageways or non-cooled passage 4, be directly connected to send out The entrance pipeline of motivation.Control at the air entered between two passages that ducts upstream combines by changing, thus can adjust The inlet temperature of joint electromotor.

In cylinder exit, burning gases guide towards exhausting loop, and are passed into the turbine of turbocharger 104, this turbocharger makes the part extraction of they residual amount of energy, to actuate corresponding compressor 102.Generally, these rows Gas then passed through particulate filter and/or catalytic converter 105 from vehicle before discharging.

In the case of high voltage structures, as it is shown in figure 1, a part of aerofluxus is by the high pressure valve via turbine 104 located upstream In the air inlet loop in 106 downstreams, junction being recycled to two exit passageways 3 and 4.

In the case of low-pressure structure, as in figure 2 it is shown, it appeared that the element identical with high voltage structures, simply aerofluxus Recycle sections removes in turbine 104 downstream, and via low pressure valve 107 in compressor 102 upstream of turbocharger by again Inject.In air inlet loop, the fluid of circulation is then not only air, but air and the mixture of aerofluxus.But, double throttle device 1 Operation in two structures, keep identical.

Referring now to Fig. 3, it can be seen that the body 1 of double throttle device, it has access road 2 and two exit passageways 3 and 4. First passage 3 is connectable to cooler 5, and second channel 4 can make this cooler short circuit directly to link with entrance pipeline. By the mobile flashboard around axle, controlling each generation to two passages 3 and 4, the axle that this axle is arranged on for first passage props up Support member 7 and the axle support member 8 for second channel.Control on each passage is rotated by flashboard and performs, this flashboard or More or less stop the air by respective channel or gas stream.Body 1 also includes actuating motor for the electricity of two flashboards Support member 6, described flashboard is connected to it by appropriate exercise system.

Fig. 4 is shown in the flashboard 10 in the version being designed to cooling duct 3 and controls device.Flashboard 11 is arranged on On its axle 11, its lower end can rotate in the axle support member 7 of reducer.Flashboard it is possible in rotary moving relative to body 1. For the upper end of axle 11, it carries the first upper plate 12 then, and this upper end is rigidly fixed to upper plate, thus described upper plate Rotate the rotation of same magnitude triggering flashboard 10.Axle 11 is also equipped with lower plate 13, its situation about rotating at upper plate 11 Under, rotate freely around axle and do not driven as result.Finally, axle 11 has band gear 14, and it rotates freely around described axle, Described axle allow according to the principle that will be explained below drive two plates one or the other or the two.Band gear 14 is along one Direction or other direction are driven by little gear, and this little gear is arranged on the output shaft of the electric notor controlled by ECU 103.Should It is the actuation member of two plates with gear, and is finally the keeper of flashboard 10.

Between two plates 12 and 13, there is spinning reduction spring 15 location, and it tends to rotate in mutually opposite directions two plates. To this end, each plate includes notch, being respectively labeled as 121 and 131, it forms housing, and the respective end of back-moving spring 15 is contained in Wherein, and absorb the power that applied by spring.

With reference to Fig. 4 to 6, upper plate 12 and lower plate 13 are described.Upper plate 12 has the groove 122 of mortise type, axle 11 carry Tenon be plugged into secure it to axle, lower plate 13 includes that tubular support 132, axle 11 can rotate freely wherein. Thus, it is ensured that upper plate 12 is fixed to axle and lower plate 13 rotating freely relative to this axle.The each of said two plate also includes two The individual protuberance radially extended, in order to short adjacency section 123 in formation, under short adjacency section 133 and upper long adjacency section 124, lower long neighbour Meeting portion 134, they have the purpose constituting described plate relative to the rotation limit around parts.Long adjacency section 124 and 134 is with fixed Fixing adjacency section on the body, position cooperates with having and limits the purpose rotated relative to the body 1 of double throttle device, and short neighbour Connect portion's support member acting on the compression driving plate and/or spring 15 under the action of band gear 14.Described adjacency section (long and Short) Angle Position be defined, in order to the position of gate is adapted to the associative operation of motor.

With reference to Fig. 7, band gear 14 has the form of dish, and this dish has tooth in the major part of the circumference of its exterior face 141, Rotate so as to driven by the little gear actuating motor of double throttle device.At its center, it includes the post axially extended Shape pipe 142, it forms the bearing being used for controlling the axle 11 of the flashboard of the stream by related channel program.Finally, on periphery, band gear Including driving finger piece 143, drive finger piece axially to extend and there is the upper short neighbour of two plates 12 and 13 with first passage Connect portion 123 and under the function of short adjacency section 133 cooperation.Its radial distance away from axle 11 thus with the short adjacency section of two plates away from The radial distance of axle 11 is generally equalized, to guarantee that it drives.On the contrary, it is less than the radial distance away from axle 11 of long adjacency section, with Just can pass through in the region of respective corners sector in they fronts, and thus allow band gear rotation continue, and not with meaning Figure is interfered for the fixing adjacency section of the long adjacency section of plate.

At this, the second channel corresponding to non-cooled passage 4 includes the control device similar with described control device, simply It only includes a upper plate, the referred to as second upper plate 22, and does not has lower plate.The finger piece 243 of the second band gear 24 is the most only with upper Short adjacency section 223 cooperates.In this configuration, on the one hand the back-moving spring 25 of second channel passes through in its end to position on upper plate Notch, on the other hand carried by fixing adjacency section, this fixing adjacency section is positioned on the body of double throttle device.Described element Schematically show in Figure 10 is to 16.Every other element is similar to those elements of first passage.Also it is clear that First passage may be selected to be non-cooled passage, and it then includes two plates, and second channel is thus cooling duct, and it then can only include Single plate.

Referring now to Fig. 8 and 9, it is seen that the relative development of the location of two flashboards under the control action of double throttle device, with And the driving kinematics system of two band gears 14 and 24.In this first embodiment, the little gear of motor and two bands are actuated A direct engagement in gear, second is engaged with first and thus rotates in mutually opposite directions.This first embodiment can be also Being carried out by little gear, this little gear and two band gear engagements, it rotates the most in same direction, the driving fortune of the second flashboard Therefore dynamic system adapts.

In these figures, actuating under the entraimnent that motor causes lacking or losing, i.e., first leads to rest position The position that first plate 12 in road 3 is used with the second upper plate 22 of 13 and second channel 4 is corresponding with reference axis.This is The position being denoted as " 0 " occupied by flashboard under the action of the spring 15 and 25 of each passage.At this rest position, first passage The flashboard 10 of 3 is opened, and the flashboard of second channel 4 cuts out.Relative to rest position, actuating motor can rotate by drive belt gear There is amplitude-α in one direction and rotate amplitude-2 α having in another direction.

In the drawings, the rotation of the angle-α represented by branch A that band gear is carried out causes the flashboard of first passage to be closed, simultaneously The flashboard of second channel remains turned-off.On the contrary, the positive rotation of the angle α represented by branch B that band gear is carried out causes first passage Flashboard close and second channel flashboard open both.Finally, the continuation rotation of the second jiao of α represented by branch C is carried out Transduction causes the flashboard of second channel and closes, and the flashboard of first passage remains turned-off.On the one hand Fig. 9 describes, and these motions are to throttling Device is for entering the impact of the active surface that fluid passes through in two passages, and therefore impact on controlled stream, another Aspect describes, and they convection cells are the impact of fluid temperature (F.T.) when two passage meets are downstream into cylinder.

Branch A corresponds to the pass the control of the fluid of single first passage 3.By being cooling duct by this channel selecting, The temperature obtained keeps constant and is equal to the temperature obtained in the exit of cooler, because all fluids are via described cooling Passage passes through.Branch B is corresponding to the regulation of fluid temperature (F.T.), and does not has the control to its volume.For opening and closing two locks The kinematics system of plate is shown in which as they are complimentary to one another (but at this not necessarily), and this allows to for branch B's All positions, it is thus achieved that constant outlet stream.Finally, branch C is corresponding to the control of the stream on the most single second channel and the most right Ying Yu is in the control of the stream of the fluid of non-cooled temperature.

Referring now to Figure 10 to 13, the first embodiment allowing such operation will be disclosed.These figures show band gear And upper and lower plate is in branch A, B of Fig. 8 and the relative position in the extreme position of C.Figure 11 correspond to rest position, Figure 10, 12 and the 13 corresponding rotations corresponding respectively to-α ,+α and+2 α.Two bands in these Figure 10,12 and 13, in rest position The position of the finger piece 143 and 243 of gear is illustrated by the broken lines.The band gear 14 of last first passage is illustrated twice, and indicates Go out the position in the region at upper plate 12 of finger piece 143 and the region of lower plate 13.

Figure 10 demonstrates that the motor rotation of actuating the flashboard 10 of first passage 3 is brought into closed position (actuates motor The anglec of rotation-α, at this equal to-83 °) after position in the extreme structure of branch A of the various elements of double throttle device.Due to The tooth being engaged with each other with gear and their only one engage with the little gear actuating motor, by they selected structures, The band gear 14 and 24 of two passages has been rotated in the opposite sense.As result, with reference to turning clockwise direction, described band tooth The finger piece 143 and 243 of wheel has rotated 83 ° (for first finger pieces) and-83 ° (for second finger piece).Lead to second On road 4, upper plate 22 does not rotate, by the long fixing neighbour of its second long adjacency section 224 and second be positioned on double throttle device body 1 Meet portion 225 to cooperate and be blocked.In all positions of actuating motor corresponding with the point of branch A, the flashboard of second channel 4 Remain turned-off.

About first passage 3, the rotation actuating motor causes the equivalent of upper plate 12 to rotate, and it is closed with described first passage The rotation closing the first finger piece 143 being associated drives.Meanwhile, the rotation of the first band gear 14 does not change taking of lower plate 13 To, cooperated with the lower fixing adjacency section 135 being positioned on double throttle device body 1 by its long adjacency section 134 and be blocked for rotation. The rotation of upper plate 12 and the compression not rotating the spring 15 allowing first passage of lower plate 13, cause the circle at two ends at spring 15 Relative to 83 ° of biasings of its biasing in rest position between being orientated in week.This compression allows when actuating motor by its angle from-α When returning to 0 °, the first upper plate automatically returns to rest position.

In fig. 11, two upper and lower plates of first passage and the upper plate of second channel at their rest position, its The point met corresponding to branch A and B.Only under the pre-tensioned effect of spring 15 and 25 being supplied to the two passage, second The upper plate 22 of passage contacts with fixing adjacency section 225 and 135 respectively with the lower plate 13 of first passage, in order to guarantee that flashboard is at it Being automatically positioned, particularly in the case of actuating motor failure of rest position.In this position, first passage 3 is beaten completely Open, it is allowed to entrance stream is by cooling duct, and second channel 4 is closed, for security reasons allow cylinder to be supplied with as far as possible The fluid of minimum temperature.

Figure 12 illustrates the position in each element extreme structure at the point that branch B and branch C meets, i.e. incited somebody to action The flashboard 10 of first passage 3 is gradually brought into closed position and the rush being gradually brought in open position by the flashboard of second channel After dynamic motor rotates (actuating motor rotation+α, at this equal to 83 °).It is worthwhile to note that the closed position of the first flashboard 10 be 166 ° obtained at the end of branch A, i.e. substantially at flashboard after its axle 11 completely returns to.Finger piece 143 and 243 with gear The most therefore one rotates-83 °, another rotation+83 °.(for the flashboard 10 of first passage 3, it is from position to run through branch B 0 ° advances to 83 °, position), under the action of the back-moving spring 15 of respective channel, the first the most rotated-83 ° of upper plate 12, until its Upper long adjacency section 124 adjoins with fixing adjacency section 125 on corresponding first.More specifically, simultaneously, the first finger piece 143 is Driving lower plate 13 to rotate-83 °, it has the effect not changing back-moving spring 15 compression level so that it is stay its pre-tensioner level, To drive upper plate 12.Meanwhile, the finger piece 243 of the second band gear 24 has driven the second upper plate 22 to rotate+83 °, compresses second Spring 25 returns to its rest position with permission device in the case of actuating motor failure.When electromotor be in shown in Fig. 9 complete During power, the closedown with the second flashboard 20 simultaneously of closing of the first flashboard 10 allows to retain perseverance substantially for reducer entirety Fixed effective cross-section, and it is adjusted into the temperature of fluid.

Finally, Figure 13 illustrates each element position in the extreme structure of branch C, i.e. at the flashboard by second channel 4 Gradually bring the motor second of actuating that the flashboard 10 of closed position and first passage 3 maintains the closed position into rotate after+the α of angle. The most again, the closed position of the second flashboard is in away from about 180 °, the closed position obtained at the end of branch A.Described band The finger piece 143 and 243 of gear continues their rotation with the second value α.Running through branch C, the first upper plate 12 keeps by long on it Fix the cooperation of adjacency section 125 on adjacency section 124 against first and be blocked, and lower plate 13 rotation angle α is so that the first bullet Spring 15 tensioning.Meanwhile, the upper plate 22 of second channel has continued it and has rotated, and drives corresponding flashboard, and guarantees to lead to via second The fluid stream in road 4 is in the control of steady temperature, because first passage keeps completely closing.The rotation of upper plate 22 also has with complementation Mode compresses the effect of the second spring 25.The compression of two springs 15 and 25 is thus combined, to allow device to return to theirs Rest position.

Referring now to Figure 14 to 16, the kinematics system of the figure implementing Fig. 8 and 9 can be seen in further view.These figures Describe the displacement of element during branch A, B and C, be represented by dotted lines the quilt when it is corresponding to the rest position of corresponding flashboard The position that plate occupies.Plate 12,13 and 22 illustrates by changing the rectangle of position.Corresponding to the state of flashboard of location of plate in institute State in rectangle and open with " O " expression, represent with " F " and close.Plate links together along the displacement of branch A, B and C also by arrow Two position display.

Figure 14 illustrates the sequence on branch A, wherein, actuates motor from 0 ° to-α, i.e. the flashboard 10 of first passage 3 is not busy from it Progressively closing off of seated position (corresponding to fully open position).Its also with the phase of control entering fluid on single first passage 3 Correspondence, second channel 4 keeps being sealed by the second flashboard 20.On this branch A, the finger piece 143 of the first band gear 14 drives The upper plate 12 of one passage compresses the first spring 15.First upper plate 12 is shown as in its initial fully open position being labeled as O Unblanketed, be shown as in closed position band shade and be labeled as F.The lower plate 13 lower fixing adjacency section by reducer body 135 are held in place, and this adjacency section prevents it from rotating and allows the compression of the first spring 15.Second channel does not has during this branch A Being affected, the second spring 25 is in its pre-tensioned positions, and under the effect of described second spring 25, the second upper plate 22 is in Its rest position, is supported by second and fixes adjacency section 225.

Figure 15 shows each element position on branch B, and it controls corresponding to the so-called ratio entering fluid.Branch The control of the variable proportion of the fluid being particularly corresponding to a little pass through in two passages of B.The finger of the first band gear 14 Shape thing 143 promotes lower plate 13 after it the most substantially carries out half-turn rotation and progressively closes off the first flashboard 10.First spring 15 In this branch B, be maintained at pre-tensioned positions, if the first upper plate 12 not with fix adjacency section 125 on first and contact and drive First upper plate 12.Meanwhile, the second finger piece 243 is gradually opened second channel 4, promotes the second upper plate 22 and the followed by second lock Plate 20.Second spring 25 is little by little compressed, contrary with the first spring, and it runs through branch B and keeps pre-tensioner.In branch, B terminates Time, the first flashboard 10 completely closes, and the second flashboard 20 fully opens.As noted above, the kinematics system priori of two flashboards Be designed as, for two passages 3 and 4 the two, steady flow is kept a little for branch B.

Figure 16 finally shows the control to second channel 4 of the displacement by the second upper plate 22 under the effect of the second band gear 24 System.More specifically, the finger piece 243 of the second band gear 24 drives the short adjacency section 223 of the second upper plate, and followed by second channel Flashboard, this flashboard progressively closes off.Meanwhile, the first upper plate 12 keeps abutting against fixing adjacency section 125 on first, and the first bullet The compression of spring 15 is driven rotation to increase along with the first lower plate 13 by the first finger piece 143, and the first upper plate 12 is in adjacent simultaneously In.The compression of two springs 15,25 is combined.

Referring now to Figure 17 to 21, will describe the feature of the second embodiment, it is to there is single spring and epicyclic train of gears, This epicyclic train includes two band gears.In this embodiment, actuating motor does not has direct drive belt gear, but it is via rush Dynamic device effect, this actuator rotates the band gear of in the planetary carrier engaged with band gear or two passages of rotation, It is second channel in this case, edge and the most contrary direction.Flashboard is also driven, and for first passage, passes through planetary gear The axle of support, for second channel, by actuator direct acting band gear.There is with first embodiment identical function The element of two embodiments has same reference numerals, and no longer describes.

Figure 17 is the perspective schematic view of this device, and Figure 18 to 21 is identical this regarding launched in a plane simultaneously Figure.In Figure 19, device describes at rest position, i.e. the flashboard 10 of first passage is opened, and the flashboard of second channel cuts out.Fixed Figure 11's that position is thus similar to that in first embodiment, i.e. the transition position between branch A and B.Figure 18 is corresponding to driving motor The anglec of rotation-α, Figure 20 and 21 is corresponding to the described driving motor anglec of rotation+α and+2 α respectively simultaneously.

First band gear 14 operates as the outer shroud of epicyclic train of gears, and the second band gear 24 is as the planet of this gear train Wheel operation.With the planetary gear 33 that planetary carrier 34 is rotatably connected is accommodated between described band gear, and provide comprehensive to it Driving.Driven element 30 in rotary moving around the axis of epicyclic train of gears by actuate that motor (not shown) actuates, and have and drive Untie-sell 31, is the drive pin of the finger piece 243 of the second band gear and in a second situation for by planetary gear in the first case The drive pin of the 3rd finger piece 343 of support 34 carrying.Drive element show with solid line in fig. 17, respectively with the second band tooth Two positions that the finger piece 243 of wheel engages and engages with the finger piece 343 of planetary carrier are shown in phantom.Back-moving spring 35 are intended to push back the finger piece 343 of planetary carrier 34 from the finger piece 143 of the first band gear, and are taken back by planetary carrier The rest position of spring pre-strained state is corresponded to it.

Finally, the body 1 of double throttle device is included in a number of fixing adjacency section described below, the finger-like of band gear The finger piece of thing and planetary carrier is against this adjacency section, in order to operation epicyclic train of gears and allow two of its element rotations and 3rd stopping.

In the position-α actuating motor, it figure 18 illustrates and terminate corresponding to branch A, and actuator 30 is in completely Retracted position, it is associated with the fully closed position of the flashboard 10 of first passage.Meanwhile, the second band gear 24 is maintained at second The position that the flashboard of passage 4 is also switched off；This position is by being positioned at the first of the second channel being formed on double throttle device body 1 It is defined on fixing adjacency section 246.More specifically, run through branch A, the finger piece 243 of the second band gear keeps leading to second Described the first of road 246 fixes adjacency section contact, and therefore the second flashboard 20 remains turned-off.On the contrary, the flashboard of first passage 10 motions following planetary carrier 34, and progressively close off along this branch A from 0 °, position to-α, therefore ensure that single first passage Control on 3.For orientating the first band gear 14 of the ring of epicyclic train of gears as, it is driven by the band gear 33 of planetary carrier 34 Dynamic rotation, stops because planetary gear 24 is fixed adjacency section 246 by the first of second channel.Adjacency section is not run into along branch A.Make For contrast, spring 35 is by the first compression, and this is owing to the ring 14 of the ratio epicyclic train of gears of planetary carrier 34 rotation is slow；This pressure Contracting guarantee when drive element 30 to discharge or push back put in place set to 0 ° time, planetary carrier 34 returns to rest position.

At rest position, Figure 19 illustrate and rotate to 0 ° corresponding to actuating motor, the second finger piece as has been proposed 243 abut against it first fixes adjacency section 246, and the pin 31 of actuator 30 contacts with this second finger piece 243 simultaneously.3rd refers to Shape thing 343 also contacts with pin 31, returns to this position under the action of back-moving spring 35.The position of actuator 30 corresponds to planetary gear One position of support 34, in this position, the flashboard 10 of first passage 3 is opened.Second channel still in closed position, the first band tooth The finger piece 143 of wheel abuts against its fixing adjacency section 146.

Running through branch B, the finger piece 143 of the first band gear keeps abutting against its fixing adjacency section 146.Actuator 30 Extension promotes the second band gear 24, thus opens second channel；Meanwhile, moving at the second band gear as planetary gear effect Under work, planetary carrier 34 is driven in rotation, and this guarantees the closedown of flashboard 10 of first passage.Thus, it is thus achieved that desired ratio Control and the homeostasis entering fluid stream on two passages.At the end of branch B, as shown in Figure 20, at back-moving spring 35 Under effect, actuator 30 fully shifts with the fixing adjacency section 346 against planetary carrier for planetary carrier 34, and this is corresponding Fully closed position in first passage 3.Second band gear 24 is in the first adjacency section 246 and second channel of its second channel The second adjacency section 247 between centre position, as described below, this is corresponding to the fully open position of the second flashboard 20.

Branch C is corresponding to the bigger extension of actuator 30, and its final position figure 21 illustrates.Planetary carrier 34 is protected Hold and stopped by its fixing adjacency section 346, and epicyclic train of gears produces rotation while two band gears.Actuator 30 is sold by it Second band gear 24 is pushed back by 31 completely, and progressively closes off the flashboard of second channel 4, and first passage 3 remains turned-off simultaneously, thus Guarantee to control via the entrance fluid of single second channel.This sequence lasts, until the second finger piece 243 clashes into second channel Second adjacency section 247, it is formed in the body 1 of double throttle device.The position of this second adjacency section is corresponding to the second flashboard 20 Fully closed position, is therefore prevented from described flashboard and exceedes this fully closed position.For the first band gear, when actuator contracts again Hui Shi, it is by the rotary compression back-moving spring 35 of epicyclic train of gears, to prevent the second band gear 24 at branch C and then to divide Prop up the return on B.

Finally, this second embodiment is reappeared identical with first embodiment as shown in FIG. 8 and 9 for opening and closing two The pattern of the flashboard of individual passage 3 and 4.

In the aforementioned embodiment, during kinematics system allows flashboard 10,20 disconnects relative to another flashboard and connecing Closing, to guarantee the control function via a passage, the flashboard of another passage keeps fixing.Other spy according to the present invention Levying, this is this situation: can also be operated without disengagement kinematics system according to the double throttle device of the present invention.

As shown in figure 22, according to other feature, the body 1 of reducer includes inner shell 404, and it is divided into for including The first order 500 of the first flow channel 3 of described first flashboard 10, and include the second flow path 4 of described second flashboard 20 The second level 502.

As Figure 23 is more clearly visible that to 25, although accompanying drawing only illustrates the single-stage 500 of described inner shell 404, described shell Body is cylindrical, has circular cross section.Additionally, described first and second flashboards 10,20 include at least one seal member 414, it is disposed relative in the plane that described cylindrical housings 404 tilts and by the sidewall of circumference bus with described housing 405 cooperations, in order at least guarantee being in sealing contact between flashboard 10,20 and body 1 in an Angle Position.Described reducer is also Including controlling bar 415, it is driven by described kinematics system, and is connected to the first and second flashboards 10,20.

In other words, the body 1 of reducer is provided with inner shell 404, and it is cylindrical, has axis A, and has Circular cross-section, and defined by lateral sidewall 405.

In this case, inner shell 404 is incorporated in hole.In each level, formed and be used for being designed as passing through valve casing Entrance 406 and the outlet 407 of the passage of the fluid of body circulation are discharged to its wall, radial to axis A.This entrance 406 is relative with 407 In being in alignment with each other.They have the longitudinal axis X that the axis A with housing 404 intersects vertically in this case, and have identical Diameter.They extend beyond the lateral sidewall 405 of housing via conduit (not shown), and this conduit is incorporated in body 1 and is designed For for being connected with the loop being provided with described reducer.

By interval 409 separately, this is arranged at intervals with hole 413 to level 500,502.At one end thereof and/or another end At portion, there is laterally lid 410 location, and this is laterally covered and is extended by the end pieces 411 with axial hole 412.The hole 413 at interval 409 And/or the axial hole 410 laterally covering (one or more) is passed by described control bar 415.

Tilt component 414 is configured to the oval flashboard 416 being arranged in a plane, and this plane is relative to cylindrical housings The axis A of 404 tilts, and this flashboard is centered on described axis A, thus its periphery edge 417 and the lateral sidewall 405 of housing 4 It is permanently connected to, in order at least one given Angle Position of air locking, every grade of entrance 406 and outlet 407 are separated, with dry Turbulent stream or entrance 406 and outlet 407 are arranged as fluid communication, stream can be according to the given angle aperture of flashboard 10,20 And controlled.This periphery edge 417 thus constitutes bus G, its always sidewall 405 with housing be in sealing contact.

" tilt " to be interpreted as strictly between 0 ° to 90 °." flashboard " is interpreted as the parts with two surfaces at this, this Two surfaces tilt relative to axis A and connect via periphery edge 417.Described inclined surface can be parallel to each other.Parts have There is little thickness, i.e. much smaller than the body diameter distance between described inclined surface, the least ten times.Such as, it is dish.

It is contemplated that geometry is to guarantee the correct operation of reducer.Flashboard 416 has elliptical shape, and it has more than toroidal shell The big axis of the diameter of body 404, and there is the little axis of the diameter being significantly less than circular shell 404.In this case, toroidal shell The diameter of body 404 is also greater than fluid intake 406 and the same diameter of outlet 407.Connecting rod 415 is arranged along housing axis A, in order to Being centered on pitch, have the angle B between the clinoplain and axis A of dish, it is equal to 45 ° at this.In order to obtain and shell The constant contact of the lateral sidewall 405 of body, the big axis of dish 416 is thus substantially equal to the diameter of housing and is multiplied by √ 2.This contact can limit It is set to the wall 405 of the circular cross-section of housing 404 and corresponding to the cylinder between the bus G of the periphery edge 417 of pitch 416 Body/cylinder contact, and it is projected as circle in the plane being perpendicular to flashboard rotation axis.The little axis of flashboard 416 can be bright The aobvious diameter more than fluid intake 406 with outlet 407.

The flashboard 10,20 installation in the housing 404 of valve body does not require that troublesome adjustment operates, and it only needs to control Bar 415 is arranged as the most axially adjoining, to be felt relieved relative to fluid intake and outlet by dish 416.

Bar 415 is attached to dish 416 by assembling or be coated with molding, or is configured to have dish, in order to produces single-piece and seals Device.As an example, according to single-piece embodiment or the complex of selection, dish 416 can be made of plastics, and bar 415 is by metal system Becoming, vice versa, or the two can be made up of plastic material or metal.The axial hole 412 of end pieces 411 can be provided with guiding Bearing portion 418.Described control bar 416 can be continuous print and pass through described housing.

In the position that figure 23 illustrates, pitch 416, by entrance 406 and outlet 407 isolation, prevents fluid stream from passing through valve 1.To this end, the periphery edge 417 of pitch 416 to be divided into two individually and to seal the compartment of terrain mode of chamber hermetically by housing And fully cooperate with the sidewall 405 of cylindrical shell 404, each towards the entrance and exit passage 406 passed through for fluid, One rotation of 407.This Angle Position of pitch 416 is corresponding to the closedown of shown fluid passage.

When driving means is activated, its rotation according to expectation angle causing controlling bar 415 and flashboard 10,20, corresponding In by the constant current really of the fluid of related channel program.As the result rotated, periphery edge 417 no longer with the lateral sidewall 405 of housing Completely attach to, and be only partly to contact, because the contrary positioning parts at edge 417 is and round entrance and outlet 406 and 407 Relatively.This angle retracted position of dish allows the entrance 406 in the region of one-level and/or another grade and the stream between outlet 407 Body passes through, via the sealing inner shell of body 404.

It is worthwhile to note that reducer can operate from home position along both direction, because reducer can be more than 360 ° Upper operation.Such valve is thereby, it is ensured that cut out direction along two seal (cylinder by being adapted in circular shell by pitch Body-cylinder contact), this dish can be installed along both direction by any way by its symmetry, and not in valve body Polarization.Additionally, shift in cylindrical wall in a linear fashion along with plate edge, this allows to the pollution avoided between dish and wall, And guarantee the automatically cleaning of valve.

In order to ensure the control principle according to the present invention, described first and second flashboards 10,20 are relative to described control bar 415 offset with respect to each with an angle, and/or described flow channel 3,4 offsets with respect to each with an angle relative to described control bar 415, The angled biasing of flashboard 10,20 is associated with the angled sheet of described fluid passage 3,4.

According to shown example, flow channel 3,4 is orientated in same direction, and the first and second flashboards 10,20 bias 60 °. In other words, align to another level from one-level in same direction in entrance and exit hole 406,407.

Figure 26 and 27 to 30 contributes to being more clearly understood that how the sequential positions occupied by flashboard 10,20 allows desired Control principle is carried out.

Figure 26 be shown in flashboard around axis A rotate during, flashboard is relative to the entrance and exit hole 406,407 of respective channel The difference passed through.When flashboard is positioned at the axis in described hole, this is fully open position.Once they are by along a side To or another direction rotate more than 60 °, corresponding flow channel is then closed.

Figure 27 a to 30a and 27b to 30b is shown respectively the position of the pitch 416 of first flashboard the 10, second flashboard 20, edge The height (mm) of the sidewall 405 of housing, this wall expands into-180 ° to+180 ° with plane graph.Flashboard 10,20 is on lateral sidewall 405 Profile 504,506 illustrated by double wave streakline, this double wave streakline thus has sinusoidal shape.Ingate 406 is corresponding to circle, fixed The heart is on figure.Outlet opening 407 each corresponds to two semicircles, is positioned at the both sides of figure.First, it is noted that arrive, no matter their angle Position, described profile 504,506 is relative to each other each at Figure 27 a and 27b, 28a and 28b, 29a and 29b and 30a and 30b 60 ° are biased between individual.

In Figure 27 a and 27b, flashboard 10,20 all cuts out, and their profile 504,506 does not has the round phase with hole 406,407 Hand over.

In Figure 28 a and 28b, the first flashboard 10 is opened, and profile 504 intersects with the circle in the hole 406,407 of first passage, and Second flashboard is still cut out, and its profile 506 does not has the circle in the hole 406,407 with second channel to intersect.Thus, control only via First passage realizes, the second flashboard 10 from the closed position shown in Figure 27 a by the fully open position shown in Figure 28 a, and Second flashboard, despite movably, continues to seal second channel.

In Figure 29 a and 28b, the first flashboard 10 is again switched off, profile 504 no longer with the hole 406,407 of first passage Circle intersects, and the second flashboard 20 is opened, and its profile 506 intersects with the circle in the hole 406,407 of second channel.The most same time control Making and perform via the first and second passages, first passage passes through to corresponding to Figure 29 a's from the fully open position of corresponding diagram 28a New closed position, and second channel passes through to the fully open position corresponding to Figure 29 b from the closed position of corresponding diagram 28b.

In Figure 30 a and 30b, two flashboards 10,20 are all again switched off, their profile 504,506 not with hole 406, The circle of 407 intersects.Thus, controlling only to perform via second channel, the second flashboard 20 is logical from the fully open position shown in Figure 29 b Cross the closed position shown in Figure 30 b, and the first flashboard 10, despite movably, continue to seal second channel.

From the position shown in Figure 27 a, 27b to the position shown in Figure 30 a, 30b, flashboard 10,20 has performed the rotation of 180 ° Turn.They can perform same loop in opposite direction, or continues their rotation, until arriving the initial position of Figure 27 a, 27b.

Described control 415 may be coupled directly to actuate motor.Described kinematics system actuates motor described in thus including Axle.

In a word, whichever embodiment, is permitted by the single gradually rotation actuating motor according to the double throttle device of the present invention Permitted to enter fluid to be controlled (according to the branch A of interengaging embodiment) via single first passage, and second channel is closed；Via list Individual second channel (the branch C in interengaging embodiment) is controlled, and first passage is closed；Or by controlling between the two channels And controlled via two passages (according to the branch B of interengaging embodiment) simultaneously.When a passage in reducer downstream towards cold But device 5 is opened, and when another passage bypassed this cooler with first passage before converging, double throttle device allows access into fluid Temperature is conditioned.It addition, by demarcating the opening and closing curve as the flashboard actuating motor anglec of rotation function, can be at this Ratio control period keeps constant ensemble stream, and the final temperature of only convection cell has an impact in this branch.
