Thus, the 2nd control grease chamber S2 lateral pressures become smaller than the 1st control grease chamber S1 sides, even if the 1st control grease chamber S1 and the 2 control grease chamber S2 area is identical, and the direction that can also strengthen makes inner shell 3 always be tailed off from the discharge-amount of spitting unit 14 is moved Dynamic trend.That is, the trend for the useless acting that always prevent oil can easily be turned into.
In the presence of the embodiment for the aerial drainage throttle orifice 16 being reduced in the 3rd control grease chamber S3 downstream provided with sectional area. Aerial drainage throttle orifice 16 plays a part of making the 3rd control grease chamber S3 oil be difficult discharge.Aerial drainage throttle orifice 16 is made as choke valve With, the discharge rate from the 3rd control grease chamber S3 positioned at upstream side is turned into micro, can be by the 3rd control grease chamber S3 The size of the oily amount of flowing suitably adjusts the 3rd control grease chamber S3 oil pressure, also can be used in the oil pressure cntrol.Separately Outside, in the case where being set to the 2nd embodiment of the specification of temperature-sensing valve 4（Reference picture 11）, for the 3rd control in pump case 1 Grease chamber S3 is without oily inflow and outflow, so without the oil pressure cntrol by the 3rd control grease chamber S3.
Then, the effect of the present invention is illustrated corresponding to various situations.First, make rotating speed for constant, oil temperature by Illustrated under the situation gradually risen.Here, rotary speed area is low rotation speed area, and specifically the speed setting of engine is 750rpm.But, low rotation speed area is not particularly limited to numerical value given here, and numerical value can also increase and decrease.In addition, in figure In, oily flowing or oil pressure transmission under various situations are represented by the arrow recorded along each stream.
(low oil temperature, invariablenes turning speed)
Low oil temperature is set as 40 °C.But, the numerical value of low oil temperature is not limited to this, and the numerical value can also increase and decrease.In low oil temperature And in low rotation speed area, as shown in Fig. 2 by discharge primary flow path J, the 1st control oil circuit J1, pressure is with the discharge pressure of spitting unit 14 To the 1st control grease chamber S1 transmission.Equally, by discharge primary flow path J, the 2nd control oil circuit J2, pressure is also with the discharge of spitting unit 14 Press to the 2nd control grease chamber S2 transmission.Also, the 1st control grease chamber S1 and the 2nd control grease chamber S2 have substantially same oil pressure and by Pressure surface is accumulated, and the 1st control grease chamber S1 control grease chambers of oil pressure P1 and the 2nd S2 respective oil pressure of oil pressure P2 acts on inner shell 3 On pressure it is roughly equal, cancel out each other.
Thus, the power of the elastic force of elastomeric element 7, the elastic acting force of elastomeric element 7 are internally only remained on housing 3 Act on as former state.In addition, in the 2nd control grease chamber S2, being discharged without the oil carried out by discharge oil circuit J6 and pressure-regulating valve 5 (reference picture 2（C）〕.
Temperature-sensing valve 4 is standard-sized sheet (reference picture 2 in low oil temperature（B）〕.Thus, the 3rd control grease chamber S3 due to oil flowing compared with Greatly, so producing high oil pressure, the high oil pressure exceedes the elastic force of elastomeric element 7, and inner shell 3 (is schemed to the 2nd control grease chamber S2 sides 2（A）Pump case 1 left side) move to greatest extent.Thus, the oily discharge-amount from spitting unit 14 turns into minimum, can make every The discharge-amount of rotation 1 week tails off, and improves specific fuel consumption.
(middle oil temperature, invariablenes turning speed)
Middle oil temperature is set as 80 °C.But, the numerical value of middle oil temperature is not limited to this, and the numerical value can also increase and decrease.In middle oil temperature And in low rotation speed area, as shown in figure 3, blade rotor 2 is low rotation speed area, so the discharge pressure from spitting unit 14 is relatively low Original state.Oil pressure is transmitted to the 1st control grease chamber S1 and the 2nd control grease chamber S2.In addition, in the 2nd control grease chamber S2, without By discharge oil circuit J6 and pressure-regulating valve 5 oil discharge (reference picture 3（C）〕.
Temperature-sensing valve 4 is due to middle oil temperature, so being half-open (reference picture 3（B）), flow path area reduces.Thus, in the 3rd control The oil mass flowed in grease chamber S3 is reduced, so oil pressure P3 declines, the power brought of the oil pressure P1 by the foregoing 1st control grease chamber S1 is added On power after the power brought by the 3rd control grease chamber S3 oil pressure P3 reduce, inner shell 3 is to the 1st control grease chamber S1 side (Fig. 3 （A）Pump case 1 right side) it is mobile.Thus, the discharge-amount often rotated 1 week increases.
(high oil temperature, invariablenes turning speed)
High oil temperature is set as 120 °C.But, the numerical value of high oil temperature is not limited to this, and the numerical value can also increase and decrease.In high oil temperature And in low rotation speed area, as shown in figure 4, blade rotor 2 is low rotation speed area, so the discharge pressure from spitting unit 14 is relatively low Original state.Oil pressure is transmitted to the 1st control grease chamber S1 and the 2nd control grease chamber S2.In addition, in the 2nd control grease chamber S2, without By discharge oil circuit J6 and pressure-regulating valve 5 oil discharge (reference picture 4（C）〕.
Temperature-sensing valve 4 is due to high oil temperature, so being fully closed (reference picture 4（B）), oily flowing stops.Thus, the 3rd control oil Room S3 oil pressure P3 turns into substantially atmospheric pressure, and the 1st control grease chamber S1 and the 2nd controls grease chamber S2 oil pressure P1 and oil pressure P2 equal, So internally only acting on the elastic acting force of flexible part 7 on housing 3, inner shell 3 controls grease chamber S1 side (Fig. 4 to the 1st （A）Pump case 1 right side) position move to greatest extent.Thus, the discharge-amount for often rotating 1 week from spitting unit 14 As maximum.
Then, situation when illustrating to make oil temperature for constant, rotation speed change.Here, oil temperature is set as 80 °C.But, oil temperature Numerical value given here is not particularly limited to, numerical value can also increase and decrease slightly.
(oil temperature constant and rotating speed 750rpm)
Engine speed is set as 750rpm.But, the numerical value is not limited to this, and the numerical value can also increase and decrease slightly.Such as Fig. 5 Shown, by the control oil circuit J1 of discharge primary flow path J and the 1st, pressure presses to the 1st control grease chamber S1 with the discharge of spitting unit 14 and passed Pass, by the control oil circuit J2 of discharge primary flow path J and the 2nd, oil pressure is also transmitted to the 2nd control grease chamber S2.
Also, the 1st control grease chamber S1 and the 2nd control grease chamber S2 have substantially same oil pressure and compression area, the 1st control The power that the control grease chambers of grease chamber S1 oil pressure P1 and the 2nd S2 respective oil pressure of oil pressure P2 is acted on inner shell 3 is roughly equal, Cancel out each other.The power of the elastic force of elastomeric element 7 is internally only remained on housing 3, the elastic acting force of elastomeric element 7 is as former state Ground is acted on.In addition, the power of branch path J5 oily pressure is smaller than the power of elastomeric element 53, it is impossible to slide valve 52 is moved to the 1st Level aperture position, without the oil discharge (reference picture 5 by pressure-regulating valve 5（C）〕.
Temperature-sensing valve 4 is half-open position (reference picture 5 under 80 °C（B）〕.3rd branch oil k3 via the 3rd control oil circuit J3 to 3rd control grease chamber S3 is flowed into.Thus, although the 3rd control grease chamber S3 produces oil pressure, because temperature-sensing valve 4 is half-open position, so Oil pressure is relatively low, and the power brought by the oil pressure is more slightly larger than the elastic force of elastomeric element 7, so inner shell 3 controls grease chamber S2 to the 2nd Side (Fig. 5（A）Pump case 1 left side) move slightly.Thus, the oily discharge-amount from spitting unit 14 turns into intermediateness.
(oil temperature constant and rotating speed 1000rpm)
Speed setting is 1000rpm.But, the numerical value is not limited to this, and the numerical value can also increase and decrease slightly.As shown in fig. 6, By the control oil circuit J1 of discharge primary flow path J and the 1st, pressure presses to the 1st control grease chamber S1 with the discharge of spitting unit 14 and transmitted, by The control oil circuit J2 of discharge primary flow path J and the 2nd, oil pressure is also transmitted to the 2nd control grease chamber S2.
Also, the 1st control grease chamber S1 and the 2nd control grease chamber S2 have substantially same oil pressure and compression area, the 1st control The power that the control grease chambers of grease chamber S1 oil pressure P1 and the 2nd S2 respective oil pressure of oil pressure P2 is acted on inner shell 3 is roughly equal, Cancel out each other.The power of the elastic force of elastomeric element 7 is internally only remained on housing 3, the elastic acting force of elastomeric element 7 is as former state Ground is acted on.In addition, the power of branch path J5 oily pressure is smaller than the power of elastomeric element 53, it is impossible to slide valve 52 is moved to the 1st Level aperture position, without the oil discharge (reference picture 6 by pressure-regulating valve 5（C）〕.
Temperature-sensing valve 4 is half-open position (reference picture 6（B）〕.Due to discharge primary flow path J pressure ratio 750rpm when it is high, so It is big during the 3rd branch oil k3 flow-rate ratio 750rpm.Thus, it is big during the 3rd control grease chamber S3 pressure ratio 750rpm, by the oil pressure band The power come is bigger than the elastic force of elastomeric element 7, so inner shell 3 controls grease chamber S2 side (Fig. 6 to the 2nd（A）Pump case 1 Left side) move slightly.Thus, being reduced slightly when often rotating the oily discharge-amount specific speed 750rpm of 1 week from spitting unit 14.
(oil temperature constant and rotating speed 1500rpm)
Speed setting is 1500rpm.But, the numerical value is not limited to this, and the numerical value can also increase and decrease slightly.Speed setting is The state of inner shell 3, temperature-sensing valve 4 and pressure-regulating valve 5 in the case of 1500rpm as shown in fig. 6, with being by speed setting 1000rpm situation is substantially same.Further, since rotating speed increase, so the oily discharge-amount specific speed from spitting unit 14 Increase during 1000rpm.So, in the case where being set as rotating speed 1000rpm to 1500rpm, temperature-sensing valve 4 and pressure-regulating valve 5 State to be substantially same.
(oil temperature constant and rotating speed 2000rpm)
Speed setting is 2000rpm.But, the numerical value is not limited to this, and the numerical value can also increase and decrease slightly.As shown in fig. 7, By the control oil circuit J1 of discharge primary flow path J and the 1st, pressure presses to the 1st control grease chamber S1 with the discharge of spitting unit 14 and transmitted, by The control oil circuit J2 of discharge primary flow path J and the 2nd, oil is also flowed into the 2nd control grease chamber S2, and oil pressure is transmitted to the 2nd control grease chamber S2.
By the way that rotating speed is set into 2000rpm, the discharge-amount increase from spitting unit 14, oily pressure increase.By being present in The power increase that oily press belt in branch path J5 comes, more than the elastic force of elastomeric element 53, slide valve 52 is moved.Thus, the 1st Inflow entrance 511 is connected with the 1st outlet 513, and the oil in the 2nd control grease chamber S2 is discharged (reference picture by pressure-regulating valve 5 7（C）〕.Therefore, foregoing 2nd control grease chamber S2 oil pressure P2 becomes smaller than the 1st control grease chamber S1 pressure.
Temperature-sensing valve 4 is half-open position (reference picture 7（B）), in the state of the 3rd branch oil k3 flow is many, the 3rd branch Oily k3 is flowed into via the 3rd control oil circuit J3 to the 3rd control grease chamber S3.Thus, by the 1st control grease chamber S1 and the 3rd control grease chamber S3 The power come of the oily press belt being added together exceed oily pressure by the elastic force of elastomeric element 7 and the 2nd control grease chamber S2 The power brought is made a concerted effort, and inner shell 3 is to the 2nd control grease chamber S2 side (Fig. 7（A）Pump case 1 left side) it is mobile.Thus, come It is reduction direction from the oily discharge-amount of 1 week that often rotates of spitting unit 14.
(oil temperature constant and rotating speed 2400rpm)
In fig. 8, speed setting is 2400rpm.But, the numerical value is not limited to this, and the numerical value can also increase and decrease slightly.Will Speed setting be 2400rpm in the case of temperature-sensing valve 4 state as shown in figure 8, with being 2000rpm by speed setting（Reference Fig. 7）Situation be substantially same.
By the way that rotating speed is set into 2400rpm, when rotating speed 2000rpm compared with, discharge-amount and pressure from spitting unit 14 Further increase, is present in the oily pressure increase in branch path J5.Thus, the slide valve 52 of pressure-regulating valve 5 further to Move left, pressure-regulating valve 5 temporarily becomes full-shut position, without the 2nd control grease chamber S2 oily discharge (reference picture 8（C）〕. Temperature-sensing valve 4 is half-open position (reference picture 8（B）〕.Oily pressure from the 2nd control oil circuit J2 passes to the 2nd control oil as former state Room S2, makes inner shell 3 together with elastomeric element 7 to the 1st control grease chamber S1 side (Fig. 8（A）Pump case 1 right side) it is mobile. Thus, the oily discharge-amount from spitting unit 14 is increase direction.
(oil temperature constant and rotating speed 3000rpm)
In fig .9, speed setting is 3000rpm.But, the numerical value is not limited to this, and the numerical value can also increase and decrease slightly.Turn Speed be set as 3000rpm in the case of temperature-sensing valve 4 state as shown in figure 9, with being for 2400rpm situation by speed setting Substantially same.
By the way that rotating speed is set into 3000rpm, when rotating speed 2400rpm compared with, discharge-amount and pressure from spitting unit 14 Further increase, is present in the oily pressure increase in branch path J5.Thus, the slide valve 52 of pressure-regulating valve 5 is further moved Dynamic, the 2nd inflow entrance 512 of pressure-regulating valve 5 connects with the 2nd outlet 514 and as full-gear, carries out the 2nd and control grease chamber S2 oily discharge (reference picture 9（C）〕.Thus, even if rotating speed rises, the 2nd control grease chamber S2 oil pressure rises also almost quilt entirely Suppress.As rotating speed rises, inner shell 3 controls grease chamber S2 side (Fig. 9 to the 2nd（A）Pump case 1 left side) it is mobile.Thus, Oily discharge-amount from spitting unit 14 is reduction direction.
As previously discussed, it is constant to make oil temperature, and with rotating speed is increased, by pressure-regulating valve 5, grease chamber is controlled by the 2nd The S2 appropriate discharge of oil and progress discharge stopping, making inner shell 3 to the 2nd control grease chamber S2 sides and the 1st control grease chamber S1 sidesways It is dynamic.So, even if rotating speed increase, also can remain constant by the oily discharge pressure from spitting unit 14.
In addition, in the present embodiment, temperature-sensing valve 4 is configured in the 3rd control oil circuit J3, pressure-regulating valve 5, which is configured, to be divided In branch road J5.The 3rd control oil circuit J3 length by the upstream of ratio temperature-sensing valve 4, branch path J5 ratio pressure-regulating valve 5 are by the upstream Length is arbitrary respectively, also including zero.
