In addition, guide groove 125 makes valve body 121 make the position of valve body portion 121 along the circumferencial direction swing offset of valve accommodation section 112c along the axle direction displacement of valve accommodation section 112c as long as being formed on simultaneously, also can be formed on other position of valve body 121 peripheral parts.Moreover guide groove 125 might not be formed on valve body 121 with through hole, for example, also can be cunette shape.Moreover, enlarged portion 125c expands formation towards the circumferencial direction of valve accommodation section 112c gradually from circumferencial direction limiting unit 125a end, that is, except the axle direction extension toward valve body 121 extends to form toward the circumferencial direction of valve accommodation section 112c simultaneously, also can be only extend to form from the circumferencial direction of Wang Fa accommodation section, the end 112c of circumferencial direction limiting unit 125a, in other words, also can extend to form with the direction that circumferencial direction is orthogonal from circumferencial direction limiting unit 125 courts.
The 121b of sliding cylinder portion is the chimeric through hole of state that can make feeding sleeve 126 slide with the axle direction towards valve body 121, and is formed as less than the bore of the circulation 121a of cylinder portion.Feeding sleeve 126 be with feed shaft 113a interoperation so that valve body 121 along the assembly of the axle direction displacement of valve accommodation section 112c, it forms tubular by brass material and is formed.The interior perimembranous of this feeding sleeve 126 is formed with the box thread of the male thread that is engaged in feed shaft 113a, and engages with feed shaft 113a.Moreover the peripheral part of feeding sleeve 126 is slidably embedded in the 121b of sliding cylinder portion, meanwhile, the peripheral end on diagram right side is outstanding to be formed as flange shapely, and rides over the end (end of the circulation 121a of cylinder portion) of the 121b of sliding cylinder portion.
The concavity cylinder 121c of portion is the open part of accommodating spring 127, by being formed with the roughly the same aperture of the 121a of cylinder portion of circulating.Spring 127 is for producing the elastomer that makes valve body 121 and the required pushing force of the mutual rubbing contact of feeding sleeve 126.In this example, spring 127 forms with cone shape helical spring.An end (diagram right side) of this spring 127 is housed in the concavity cylinder 121c of portion and pushes the 121b of sliding cylinder portion end, and meanwhile, another end (diagram left side) pushing is located at the pressure-bearing portion 128 of feeding sleeve 126 ends.Pressure-bearing portion 128 is in order to bear the elastic force of spring 127 and the member with pushing body 114 rubbing contact, is formed as discoideusly forming by SPC material.This pressure-bearing portion 128 with respect to feeding sleeve 126 along the circumferential direction the state of swing offset be arranged on feeding sleeve 126.Mode by this, valve body 121 and feeding sleeve 126 become the contact condition of pushing each other by the pushing force taking spring 127 as the frictional force of the limit.
Then, the standby idling that is provided with this valve body 121, feeding sleeve 126, spring 127 and pressure-bearing portion 128 is adjusted valve 120, just with inflow side opening portion 122 towards upstream passages 112a side (diagram right side), simultaneously outflow side opening portion 123 for the downstream the direction of path 112b side (diagram upside) be configured in the 112c of valve container.Thereby the 2nd opening portion 124 that idling is adjusted valve 120 can become blocking state because of valve container 112c inner peripheral surface conventionally period.And the guide groove 125 that idling is adjusted valve 120 becomes blocking state because of the inner peripheral surface of the diagram downside of valve container 112c.
With perimembranous in this guide groove 125 valve container 112c in opposite directions, to be provided with mosaic process 129 from the outstanding state of this interior perimembranous.Mosaic process 129 is for being embedded in the displacement with restriction guide groove 125 in guide groove 125, that is the assembly of limiting valve body 121 displacements, is formed as bar-shapedly forming by brass material.This mosaic process 129 is pressed in the set through hole that penetrates into valve container 112c from main body 111 outsides, and outstanding with predetermined overhang from the interior perimembranous of valve container 112c.
On the other hand, at the crankshaft 105 of engine 101, link dynamic transfer unit 200 via main actuation gear 105a.Power transmitting deice 200, for the mechanical device that the rotary driving force that engine 101 is produced carries out speed change and transmits with multiple gear stage, is mainly made up of clutch 210 and variable-speed motor 220.
On the bang path that clutch 210 is the rotary driving force that produces at engine 101, be configured between engine 101 and variable-speed motor 220, and the rotary driving force that this engine 101 is produced mechanical device that variable-speed motor 220 is transmitted and interdicted.This clutch 210 is accepted the rotary driving force from engine 101 via the main drive gear 201 that is engaged in main actuation gear 105a.
This clutch 210 is arranged on a tip side (diagram right side) of the main shaft 221 extending from variable-speed motor 220 axle shapes, and in order to being provided with the friction plate 211 of not shown friction member and the state of steel plate clutch plate 212 alternate configurations multi-discs processed, be housed in respectively in rotatable mode that clutch box 213 is interior to be formed.And, this clutch 210 is by rotariling actuate in one mode with connecting airtight of clutch plate 212 by friction plate 211, make the rotary driving force of engine 101 be delivered to variable-speed motor 220, simultaneously, by the releasing of friction plate 211 and clutch plate 212 tightlock status, and the transmission of the rotary driving force of disconnection engine 101 to variable-speed motor 220.
On the other hand, variable-speed motor 220 for example, carries out speed change with multiple gear stage (, 4 sections of speed changes) and is delivered to the mechanical device of driving wheel for the rotary driving force that engine 101 is produced.The formation of this variable-speed motor 220 makes to be connected to via clutch 210 main shaft 221 and counter axle 222 configuration parallel to each other that is connected to driving wheel of the crankshaft 105 of engine 101, meanwhile, be provided with at this 222,2 main shafts, 221 sum counter axle the multiple gear trains that form multiple gear stage of differing from one another of gear ratio.The multiple gear trains that are arranged on 222, described main shaft 221 sum counter axle are formed with the multiple counter shaftgear 222a that are separately positioned on multiple mainshaft gear 221a of main shaft 221 and are arranged on counter axle 222, and described mainshaft gear 221a and counter shaftgear 222a make to be configured between gear toward each other a pair of, and keep engagement always.
Moreover, described mainshaft gear 221a and counter shaftgear 222a are formed on sincere sub-223a and embedding hole 223b side toward each other, and sincere sub-223a and embedding hole 223b are embedded in the each mainshaft gear 221a adjacent one another are and the each counter shaftgear 222a that form 1 gear stage each other.Mode by this, the each mainshaft gear 221a adjacent one another are and the each counter shaftgear 222a that form 1 gear stage have just formed the mode that is connected to each other and separates on main shaft 221 and counter axle 222.So the power transmitting deice 200 that comprises this variable-speed motor 220 just can utilize the rotary actuation of shift shaft drive motor 230 and move.
ECU300 (engine control unit) is by being formed by the micro computer that comprises CPU, ROM, RAM etc., and according to remembering in advance the control gear that at the not icon control program of ROM etc., the various actions of idling gettering quantity regulating device 100, engine 101 and power transmitting deice 200 is carried out to Comprehensive Control.Particularly, ECU300 is the gear shift control signal of exporting according to the Gear-shift switch 302 that is arranged on vehicle handgrip 301, control the various actions of spark plug 103, sparger 109, actuator 113 and shift shaft drive motor 230, and the repairing action that lowers category while carrying out respectively every gear shifting operation in the time of gear up and gear down of clutch 210 and variable-speed motor 220 and this every gear shifting operation operation.
In addition, it is to control idling gettering quantity regulating device 100 that this ECU300 has more than, and the vehicle action that is provided with idling gettering quantity regulating device 100 is carried in comprehensive control.Therefore, ECU300 each portion of engine 101 and the engine 101 that comprises power transmitting deice 200 standby be provided with to obtain control engine 101 and (for example move required information, amount of oxygen in the aperture of the revolution of engine 101, the speed of a motor vehicle, throttle valve 108, aperture, the outlet pipe of idling regulating device 120, make act amount etc. on angle of rotation, shift pattern and the clutch of the shift shaft (not shown) that power transmitting deice 200 moves) not shown sensor, and control the each control object that comprises engine 101 according to the information obtaining from described sensor.In addition, in Fig. 1, the information path of obtaining from described sensor represents with dotted line arrow.Moreover the action that power transmitting deice 200 is undertaken by the rotary actuation of shift shaft drive motor 230 also represents with dotted line arrow.
(action of idling gettering quantity regulating device 100)
Then, just the action of idling gettering quantity regulating device 100 is illustrated as constituted above.This idling gettering quantity regulating device 100 is configured in the below of seat cushion or the fuel tank of two-wheeled automotive vehicle as previously mentioned, carries out gear down and moves by vehicle driver (not shown) operation Gear-shift switch 302.In addition, this driver's of mat gear down operation and the action of the idling gettering quantity regulating device 100 that carries out operates with gear up and the action of the idling gettering quantity regulating device 100 that carries out is mutually the same.Therefore,, in following action specification, though be only illustrated with regard to the gear down action of variable-speed motor 220, its gear up action is also same.
Particularly, during vehicle is walked with the arbitrary gear stage in 2 sections～4 sections (also referred to as " 2 grades～4 grades "), gear stage is reduced in the gear down situation of 1 section to 1 section～3 sections (also referred to as " 1 grade～3 grades "), vehicle driver can operation setting at the Gear-shift switch 302 of handgrip 301, and ECU300 is assigned to the instruction of gear down.Then,, on one side with reference to the plotted curve shown in Fig. 4, the aperture change procedure of the idling adjustment valve 120 after this gear down operation is described on one side.
If driver carries out gear down operation to Gear-shift switch 302, Gear-shift switch 302 can be exported to ECU300 the gear down control signal of the gear shift control signal of the gear down of indicating.Action by this, ECU300 can make power transmitting deice 200 start to downgrade the gear down action of variable-speed motor 220 gear stage, and meanwhile, the repairing that lowers category while making idling regulating device 110 start to carry out gear down is moved.Now, the what is called repairing that lowers category is air-breathing to engine 101 when by gear shifting operation, makes the revolution of engine 101 sides increase and approaches the operation of variable-speed motor 220 side revolutions.
In the time inputting gear down control signal from Gear-shift switch 302, ECU300 can make idling adjust the only pulse signal to air suction way 107 standard-sized sheets of valve 120 to actuator 113 outputs of idling regulating device 110 immediately.On the other hand, idling regulating device 110 is as shown in Fig. 5 (a)～(d), in the time of vehicle to run, (with reference to Fig. 2 (a)～(d)) is displaced to diagram left side with prearranging quatity from the icon low order end position of valve accommodation section 112c to make idling adjust valve 120, become outflow side opening portion 123 with prearranging quatity opening the state at downstream passages 112b.In this case, be the required inferior limit of idling of engine 101 toward the aperture of the opening amount of downstream passages 112b as the outflow side opening portion 123 of idling adjustment valve 120.
Then, adjust valve 120 receive the pulse signal that makes idling adjust valve 120 standard-sized sheets from ECU300 by idling, idling regulating device 110 can start to make actuator 113 to rotarily actuate.In this case, idling is adjusted valve 120 and is made outflow side opening portion 123 path 112b side displacement downstream by the feed screw mechanism being made up of feed shaft 113a and feeding sleeve 126.In addition, in this case, idling is adjusted valve 120 can be owing to being embedded in circumferencial direction limiting unit 125a, the 125b of the guide groove 125 that is formed on valve body 121 with the state of being seized on both sides by the arms by mosaic process 129, and valve body portion 121 is restricted toward the displacement of circumferencial direction, therefore only can be towards the axle direction displacement of valve accommodation section 112c.
Idling is adjusted valve 120 and is started after displacement, in the downstream passages 112b of shunt access 112, along with the increase of outflow side opening portion 123 to downstream passages 112b aperture, the air quantity of carrying from idling adjustment valve 120 is increased with certain proportion.Then, while making mosaic process 129 arrive the enlarged portion 125c of guide groove 125 because of the displacement of idling adjustment valve 120, because valve body 121 forms the state of allowing toward the circumferencial direction swing offset of valve body 121, thus mosaic process 129 can in the scope till colliding enlarged portion 125c with swing offset together with the rotary actuation of feed shaft 113a.
By the swing offset of this valve body 121, will as shown in Fig. 6 (a)～(d), become by the 2nd opening portion 124 path 112b for the downstream, to replace outflow side opening portion 123 state of path 112b for the downstream.In this case, to form as previously mentioned compared with outflow side opening portion 123 be large opening area to the 2nd opening portion 124.What therefore, gettering quantity ratio can be rapid from the larger air of the gettering quantity of outflow side opening portion 123 is supplied to downstream passages 112b.By this, engine 101 is to make revolution increase because idling regulating device 110 is air-breathing to cylinder 102.In addition, past downstream passages 112b's is air-breathing in the time that outflow side opening portion 123 is switched to the 2nd opening portion 124, because the peripheral part of valve body 121 is present between outflow side opening portion 123 and the 2nd opening portion 124, strictly speaking, if the aperture toward downstream passages 112b becomes 0 (zero), will become and not carry out air-breathing situation completely.But in Fig. 4 because 0 the time of becoming only have in a flash, so omit its sign.
In this case, use traditional adjustment valve to lower category in the engine of repairing, because the gettering quantity toward cylinder 102 only increases gradually according to the increase of outflow side opening portion 123 apertures, so the rising of engine revolution will expend time in, the CLV ceiling limit value of revolution is also low simultaneously.On the other hand, being equiped with in the engine 101 of idling gettering quantity regulating device 100 of the present invention, because the air-breathing of past downstream passages 112b is to be switched to the 2nd opening portion 124 that aperture efficiency outflow side opening portion 123 is large, so can carry out at short notice a large amount of air-breathing, revolution upper act at short notice, meanwhile, the CLV ceiling limit value of revolution is also higher.
Moreover, valve body 121 along guide groove 125 in the situation of circumferencial direction swing offset, idling is adjusted the pressure-bearing portion 128 of valve 120 and can be subject to the pushing of the pushing body 114 rotariling actuate together with feed shaft 113a.By this, valve body 121 can, again by the rotary driving force transmitting from pushing body 114 outside feed shaft 113a, be rotated displacement with stronger rotating force.
On the other hand, ECU300 lowers category in repairing action sign on assigning mat idling gettering quantity regulating device 100, power transmitting deice 200 is assigned variable-speed motor 220 and started the instruction of gear down action.Particularly, power transmitting deice 200 makes the friction plate 211 of clutch 210 start after separating action with clutch plate 212 by the rotary actuation of shift shaft drive motor 230, and sincere sub 223 of variable-speed motor 220 is just extracted out from embedding hole 223b.
In this case, engine 101 be in undertaken by idling gettering quantity regulating device 100 lower category repairing action and the state that makes revolution increase.Therefore, in the deceleration torsion (so-called engine braking torque force) of variable-speed motor 220 meetings in variable-speed motor 220 reduces, because the upper act that starts of clutch 210 is lowered the rotary driving force that is delivered to variable-speed motor 220 from engine 101, make sincere sub-223a become the state of easily extracting out from embedding hole 223b.By this, the present situation gear stage that variable-speed motor 220 just can carry out in gear shifting operation is smoothly eliminated.
Carried out, after the elimination of present situation gear stage, switching to new gear stage.
Then, power transmitting deice 200 is after clutch 210 disconnects the transmit mode of power because of friction plate 211 with separating of clutch plate 212, and variable-speed motor 220 can make the sincere sub-223a in new gear stage be fitted to embedding hole 223b to carry out gear stage switching.In this case, power transmitting deice 200, because the revolution of engine 101 rises because of the aforementioned repairing that lowers category, carries out gear down therefore can suppress the steep shake of gear shift.That is, because the engine 101 that can produce by idling gettering quantity regulating device 100 lowers category repairing, the revolution difference of the revolution of engine 101 and wheel side (counter axle 222) is reduced, therefore quick joining that can mat clutch 210 make torsion not the what is called of transmit mode lose the time shorten of torsion, to reduce driver's uncomfortable feeling.
In addition, ECU300 indicates to idling gettering quantity regulating device 100 the lower category opportunity of repairing action and the opportunity of power transmitting deice 200 being indicated to gear down action, can be simultaneously, can be also the instruction of carrying out again another after one of them instruction of execution.In addition, ECU300 also can driver operate Gear-shift switch 302 and outside the gear down operation carried out as trigger timing, for example, ECU300 itself can according to the walking states judgement of vehicle must gear down and the action of carrying out gear down as trigger timing.That is ECU300 is equivalent to control device involved in the present invention.And power transmitting deice 200 also can respond from the gear down action instruction of ECU300 variable-speed motor 220 is started after the elimination action of present situation gear stage, starts the friction plate 211 of clutch 210 and the separating action of clutch plate 212.
On the other hand, ECU300 adjusts after the pulse signal of valve 120 standard-sized sheets idling in output, and the wait scheduled time goes over, then 113 outputs make idling adjustment valve 120 fix on the pulse signal of idling mode aperture to actuator.In this case, making idling adjust pulse signal that valve 120 fixes on idling mode aperture is to make the opposite direction of actuator 113 when adjusting valve 120 standard-sized sheet with idling with only and the signal that the amount of same degree is rotated when standard-sized sheet.Moreover, in output, idling is adjusted after the pulse signal of valve 120 standard-sized sheets, until output makes idling adjustment valve 120 fix on the scheduled wait time of the pulse signal of idling mode aperture, supply with countercylinder 102 the repairing required air quantity that lowers category, have the sufficient time, the time in general 0.1～1 second is just very suitable.By this, because valve body 121 forms mosaic process 129 and be positioned at the enlarged portion 125c of guide groove 125, and allowed towards the state of circumferencial direction swing offset, so can feed shaft 113a rotarily actuate in, the scope till mosaic process 129 collides circumferencial direction limiting unit 125b towards with aforementioned contrary direction rotation displacement.
By the swing offset of this valve body 121, outflow side opening portion 123 replaces once again the 2nd opening portion 124 and faces downstream passages 112b.Therefore,, toward the gettering quantity of downstream passages 112b, sharply revert to the gettering quantity via outflow side opening portion 123.In this case, compare with conventional art, because idling regulating device 110 can reduce the gettering quantity toward downstream passages 112b in early days, therefore can be suppressed at the air quantity sucking when idling is adjusted the closing motion of valve 120.That is, because adjusting the closing motion of valve 120, idling can make the revolution of engine 101 sharply reduce, therefore can prevent that the revolution because of engine 101 too much accelerates suddenly in the time connecting clutch 210.In addition, even in the time being switched to outflow side opening portion 123 toward downstream passages 112b air-breathing from the 2nd opening portion 124, with aforementioned same, will become and do not carry out air-breathing situation completely if become strictly speaking 0 (zero) toward the aperture of downstream passages 112b.But, in Fig. 4, because it is short to become 0 time compole, only have in a flash, so omit its sign.
Then, idling regulating device 110 again mat actuator 113 rotary actuation again and along guide groove 125 in the 112c of valve accommodation section towards upstream passages 112 sides (diagram right side) displacement.In this case, it is also to seize mosaic process 129 on both sides by the arms by circumferencial direction limiting unit 125a, the 125b of the guide groove 125 that is formed on valve body 121 that idling is adjusted valve 120, make to be restricted toward the displacement of valve body portion 121 circumferencial directions, therefore only towards the axle direction displacement of valve accommodation section 112c.Then, in this situation, the gettering quantity of past downstream passages 112b is along with outflow side opening portion 123 reduces the aperture of downstream passages 112b, and minimizing in certain proportion.As a result, the gettering quantity of the cylinder 102 from idling regulating device 110 toward engine 101 also reduces gradually, the gettering quantity while adjusting common idling eventually.By this, the repairing action that lowers category producing because of idling gettering quantity regulating device 100 when gear down will finish.
Also can understand from above-mentioned action specification, if according to above-mentioned example, idling gettering quantity regulating device 100 is adjusting that throttle valve 108 is shunted when the air-breathing cylinder 102 to engine 101, adjusts valve 120 and is provided with the 2nd opening portion 124 that becomes the 2nd outflow side opening portion with respect to outflow side opening portion 123 in order to adjust the idling of gettering quantity.In this case, the 2nd opening portion 124 is to be independently position as large opening is formed on to this outflow side opening portion 123 to outflow side opening portion 123 that should the 2nd opening portion 124.And ECU300 can be synchronizeed and make the 2nd opening portion 124 of idling adjustment valve 120 be communicated to shunt access 112 with the gear down action of variable-speed motor 220.Design by this, in the time of the gear down action of variable-speed motor 220, just can be supplied to suction gas via the 2nd large opening portion 124 of aperture efficiency outflow side opening portion 123 cylinder 102 of engine 101.As a result, during due to variable-speed motor 220 gear shifting operation, can make in early days the revolution of engine 101 sides increase, so the present situation gear stage in gear shifting operation can be eliminated smoothly, can effectively extenuate speed change and suddenly shake simultaneously.
In addition, implementing time of the present invention, to be not limited to above-mentioned example, in the scope of vagus escape the object of the invention not, can do various changes.In addition, the routine explanation of following each variation is used graphic in, the component part identical with above-mentioned example is accompanied by same-sign, and the description thereof will be omitted.
For example, in above-mentioned example, the 2nd opening portion 124 is arranged on outflow side opening portion 123 as the 2nd outflow side opening portion.That is, in above-mentioned example, it is interior for establishing one in order to will suck the inflow side opening portion (inflow side opening portion 122) that gas imports by adjust valve 120 in idling that idling is adjusted valve 120, meanwhile, possessing 2 outflow side opening portions (outflow side opening portion 123 and the 2nd opening portion 124) that make idling adjust the suction gas outflow in valve 120 forms.But, as long as be increased to air suction way 107 because the 2nd opening portion 124 can make gettering quantity section rank property, so might not be defined in above-mentioned example.
That is idling is adjusted valve 120 also can be located at inflow side opening portion 122 as the 2nd inflow side opening portion using the 2nd opening portion 124.Particularly, idling modulation valve 120 can be by possessing 2 by sucking gas and importing idling and adjust the inflow side opening portion (inflow side opening portion 122 and the 2nd opening portion 124) in valve 120, possesses 1 and allow idling adjust the outflow side opening portion (outflow side opening portion 123) that the suction gas in valve 120 flows out to form.In this case, formed with the opening area large compared with inflow side opening portion 122 as the 2nd opening portion 124 of the 2nd inflow side opening portion.And in this case, as long as outflow side opening portion 123 arranges 1, its opening area is than inflow side opening portion 122 and large as the 2nd opening portion 124 of inflow side certainly.In addition, in this case, also as shown in following, can, by forming 2 inflow side opening portions 122 of inflow side opening portion and the 2nd opening portion 124 and be arranged on the outer circumferential face of valve body 121,1 the outflow side opening portion 123 that forms outflow side opening portion be arranged in the mode of the axle direction opening towards valve body 121 simultaneously.
Moreover, in above-mentioned example, inflow side opening portion 122 is arranged to the axle direction opening towards valve body 121, meanwhile, outflow side opening portion 123 and the 2nd opening portion 124 are formed on to the peripheral part of valve body portion 121.But suitable decision is done according to the form of shunt access 112 in the formation position of inflow side opening portion 122, outflow side opening portion 123 and the 2nd opening portion 124 of valve body 121, might not be defined in above-mentioned example.For example, also 3 of inflow side opening portion 122, outflow side opening portion 123 and the 2nd opening portions 124 etc. all can be arranged to the peripheral part of valve body 121.And, the 2nd opening portion 124 is provided as in the situation of the 2nd inflow side opening portion, also inflow side opening portion 122 and the 2nd opening portion 124 can be formed on to peripheral part towards the axle direction of valve body portion 121, meanwhile, also outflow side opening portion 123 can be arranged in the mode of the axle direction opening towards valve body 121.
In described situation, inflow side opening portion 122, outflow side opening portion 123 and the 2nd opening portion 124 can also belong to certain towards corresponding respectively upstream passages 112a or downstream passages 112b.That is, shunt access 112 is fastened in the pass of each formation position with inflow side opening portion 122, outflow side opening portion 123 and the 2nd opening portion 124, also be as long as form with form freely, not necessarily will as above-mentioned example, make downstream passages 112b be formed on upstream passages 112a (valve container 112c) with L word shape roughly.Thereby it is also except idling is adjusted the form of valve 120 displacements that idling in shunt access 112 adjusts that valve 120 apertures change, if can make idling adjust valve 120 towards change shape with independent mode or appropriately combined mode.
Moreover, in above-mentioned example, for make idling adjust valve 120 in the axle direction displacement towards valve accommodation section 112c towards circumferencial direction swing offset, and the guiding mechanism that uses the conveying screw mechanism that form by feed shaft 113a and feeding sleeve 126t and formed by guide groove 125 and mosaic process.And, adjust valve 120 driving sources by the actuator 113 forming using stepper motor as idling and drive.But, make idling adjust the position of valve 120 or needn't be defined in above-mentioned example towards the mechanism and the driving source thereof that change, can certainly use other mechanism and driving source.For example, also can only make idling adjustment valve 120 swing offsets flow out the switching action of opening portion 123 and the 2nd opening portion 124 by stepper motor or servomotor.
In addition,, in above-mentioned example, in order to make idling adjust the more certain rotation of valve 120, idling regulating device 110 forms to possess the clutch mechanism being made up of pushing body 114 and pressure-bearing portion 128.But idling regulating device 110 also can omit clutch mechanism and form.For example, as shown in Figure 7, make the diagram left end of feeding sleeve 126 protrude flange shape and ride over the 121b of the sliding cylinder portion end (end of the concavity cylinder 121c of portion) of valve body 121, simultaneously, diagram right-hand end is extended to form in the circulation 121a of cylinder portion, and with means of fixation, seat board 126a is set.And, between this seat board 126a and the circulation 121a of cylinder portion end (end of the 121b of sliding cylinder portion), configure spring 127.Design by this, idling regulating device 110 just can carry out same action completely in above-mentioned example except clutch operating.In addition; in above-mentioned example and this variation example; adjust valve 120 because certain reason is cannot be towards axle direction displacement and towards circumferencial direction swing offset time in idling; spring 127 can be brought into play the function as protective gear, to guarantee the rotary actuation of actuator 113 and to prevent that excessive load is applied to actuator 113.Thereby, not needing in the situation of this protective gear function, also can omit spring 127.In this case, feed shaft 113a can directly or via feeding sleeve 126 be connected in valve body 121.
Moreover, in above-mentioned example, the 2nd opening portion 124 is formed as square.But if the 2nd opening portion 124 is set as than the larger opening of outflow side opening portion 123 (be provided as in the situation of the 2nd inflow side opening portion at the 2nd opening portion 124, refer to inflow side opening portion 122), this shape is just not limited to above-mentioned example.For example, the 2nd opening portion 124 also can as shown in Figure 8, form to arrange towards the narrow pre-opening portion 124a of outflow side opening portion 123 sides formation A/F.If design according to this, idling regulating device 110 can prevent that adjusting because of idling the tightness that the 2nd opening portion 124 of valve 120 causes reduces, and can make the 2nd opening portion 124 rapidly at shunt access 112 openings and expand aperture simultaneously.
In addition, in above-mentioned example, outflow side opening portion 123, to arrive the scope till the enlarged portion 125c of guide groove 125 in mosaic process 129, forms length for continuing at downstream side path 112b opening.But outflow side opening portion 123 also can be as shown in Figure 9, not yet to arrive the scope of the enlarged portion 125c of guide groove 125 in mosaic process 129, in downstream side, path 112b opening forms a length, that is, also can the length shorter than above-mentioned example form.If design according to this can make to adjust the minimizing more sharply of engine 101 revolutions that the closing motion of valve 120 produces because of idling, can more effectively prevent the acceleration suddenly too much causing because of engine 101 revolutions when connecting clutch 210.
Moreover in above-mentioned example, ECU300 is configured in the time power transmitting deice 200 being carried out to gear down action, idling regulating device 100 is carried out to the mode of the repairing action that lowers category.But, if the mode of carrying out and forming is synchronizeed in the repairing action that lowers category of idling regulating device 100 with the gear shifting operation of power transmitting deice 200, be just not limited to above-mentioned example.That is, ECU300 also can be configured to only in the time power transmitting deice 200 being carried out to gear up action or gear down action, just idling regulating device 100 is carried out the mode of the repairing action that lowers category, also can be configured in the time that gear up move and respectively idling regulating device 100 be carried out to the mode that the repairing that lowers category is moved when gear down action.
