The order of these actions is: when connecting (during installation), after seal member 33 being contacted with the inside surface of the tube portion 541 that imports parts 54 guarantee sealing, front end by interlock projection 544 is opened the control valve 61 of valve system 6, communication of fluid send into path, then, admittedly and second ring, 44 rotations of tiing up mechanism 4 become lock-out state.On the other hand, during releasing (when taking off), admittedly and tie up second ring, the 44 rotation states that unlock of mechanism 4, then, control valve 61 cuts out and stops connection, and finally sealed parts 33 separate and depressurization from importing parts 54.
Below with reference to Fig. 5～Fig. 8 supply company fitting 3 and being connected of connector 2 are described, the action of mechanism 4 is tied up in wherein main explanation admittedly.
As shown in Figure 2, released state before connecting is: encircle 44 locking with projection 444 butts and push admittedly tie up the stage portion 463 and second of the spring suppport 46 of mechanism 4, the direction protrusion 432,442 of first ring, 43 and second ring 44 is positioned at second gathering sill 424 of ratchet support 42, second ring 44 can not rotate, and the 3rd ring 45 is in the confined position of down position.Under this state, first non-return valve 56 of pressure regulating device 5 cuts out, and the control valve 61 of supply company fitting 3 also is in closed condition.
The action that pushes corresponding to supply company fitting 3, the locking of connecting cylinder portion 32 is moved by the pod of first ring, 43 and second ring 44 as illustrated in fig. 7 with engaging protrusion 321, inner face 324 butts of the bottom of spring suppport 46 and supply company fitting 3 and upwards being pushed away, then, pushing stage portion 322 and first is encircled 43 lower surface butt and it is upwards pushed away.Meanwhile, second ring 44 also rises, the lower surface butt of the 3rd ring 45 that stops with lower end because of first gathering sill 421, and the 3rd encircles 45 is also upwards pushed away.In this way, second ring, 44 direction protrusion 442 stretches out from the upper end of second gathering sill 424 of ratchet support 42 and turn, by with the dip plane butt of the blade tooth 453 of the lower surface of the 3rd ring 45, second encircles 44 power that are subjected to towards sense of rotation d.
Fig. 5 represents that the maximum of supply company fitting 3 pushes state, under this state, the 3rd moving upward of ring 45 is restricted, second ring 44 contacts by the inclined-plane with the 3rd ring 45 and rotates to sense of rotation d on first ring 43, as shown in Figure 8, because of this second ring, rotation of 44, its locking to the locking of the connecting cylinder portion 32 of supply company fitting 3 medial movement and the engaging with engaging protrusion 321, can not be extracted mobile state thereby be locked as with projection 444.Under the state of Fig. 5, interlock projection 544 is opened control valve 61 and is begun sending into of fluid.
Then, pushing state from maximum begins to remove when pushing action, supply company fitting 3 is disengaged the spring 47 direction application of force of drawing back, but the locking of the connecting cylinder portion 32 of supply company fitting 3 engages ground with the locking of second ring 44 with projection 444 with engaging protrusion 321 moves downwards, and the 3rd ring 45 and first ring 43 also moves downwards integratedly.Then, when the 3rd ring 45 lower ends because of first gathering sill 421 stop to descend, second ring 44 further descends discretely with it, thereby both inclination contact separations, second ring 44 makes the front end of the direction protrusion 442 of lower end move to the dip plane of ratchet protuberance 423 since the position of second gathering sill 424 by above-mentioned rotation, and contact with this dip plane with this, because the further decline of second ring 44, thereby further rotate along its dip plane.
Then, the direction protrusion 442 of second ring 44 stops operating with buckle stage portion butt, and stops to continue to descend, and is locked with the supply company fitting 3 that projection 444 engages with the locking of this second ring 44, is in the lock-out state that is connected indissociably.
Fig. 6 is the cut-open view of this lock-out state, and the fluid that is adjusted into predetermined pressure by pressure regulating device 5 is supplied with to body 11 sides from escape hole 514.
Then, begin to remove when action from above-mentioned lock-out state, again supply company fitting 3 is pushed, first ring, 43 and second ring 44 moves upward, the bottom of second ring 44 is left and is turned from the buckle stage portion, inclined-plane by the 3rd ring 45 blade tooth 453 rotates second ring 44, retreating of supply company fitting 3 after following is mobile, the inclined-plane of second ring, 44 direction protrusion 442 contacts with inclined-plane from the buckle stage portion of ratchet protuberance 423 to second gathering sill 424, by this inclined-plane contact, second ring 44 rotates to the position in direction protrusion 442 insertions second gathering sill 424 further to sense of rotation d rotation.Position of rotation at this second ring 44, as shown in Figure 7, engaging protrusion 321 depart from projection 444 with locking and with the position consistency of pod, releasing is locked and fastened, thereby the connecting cylinder portion 32 of supply company fitting 3 can separate mobile, carry out separating action by the application of force of removing spring 47 across spring suppport 46, thus outstanding.
Described pressure regulating device 5 is used for by adjusting the pressure regulation of the valve 55 and first non-return valve 56, corresponding to the action of diaphragm 52, with pressure independent ground a pressure decompression is adjusted into predetermined secondary pressure, below its effect is described.
Fig. 6 represents the pressure regulation state, is flowed into to pressure balance chamber 530 by the fluid after adjustment valve 55 and 56 pressure regulation of first non-return valve, and decompression is for discharging from escape hole 514 behind the secondary pressure accurately.
The position that the application of force that the application of force that secondary pressure and atmospheric pressure reduction causes and pressure spring 513 cause of being maintained at diaphragm 52 balances each other.And, when the secondary pressure correspondence changes from the change of the fluid discharge of escape hole 514 discharges, the change of a pressure etc., the off normal amount of diaphragm 52 changes accordingly therewith, follow the change in location of axle 522, adjust valve 55 and 56 actions of first non-return valve, carry out on-off action from mutually different direction, secondary pressure is remained necessarily.By making pressure regulating screw 512 actions that the application of force of pressure spring 513 is changed, can set secondary pressure arbitrarily.
In addition, the voltage adjustment characteristic of the adjustment valve 55 that changes at pressure and the voltage adjustment characteristic of first non-return valve 56 are opposite characteristics mutually, and the secondary pressure that a corresponding pressure reduces rises because of the pressure regulation of adjustment valve 55, because of the pressure regulation of first non-return valve 56 reduces.And, on axle 522, the leading section of axial region 524 is accepted to adjust the pressure loss of projected area of valve 55 and lug boss 523 is accepted the projected area of first non-return valve 56 because of the effect of secondary pressure the pressure loss and is acted on simultaneously and make on axle 522 equidirectionals that retreat because of the effect of a pressure, by both combinations of voltage adjustment characteristic, make certain with respect to the secondary pressure change of a pressure variation.
Promptly, when the secondary pressure fluid reduces secondary pressure from pressure balance chamber 530 discharges, the axle 522 of diaphragm 52 advances mobile (mobile below in figure), adjust valve 55 to opening the direction action, first non-return valve 56 moves to closing direction, a pressure fluid is adjusted valve 55 decompression backs and flows into pressure balance chamber 530, thereby secondary pressure rises, adjust the degree of opening (pressure loss) of first non-return valve 56, make this secondary pressure follow the reduction of a pressure and begin to rise from setting value, when secondary pressure is setting value, off normal by diaphragm 52 makes axle 522 retreat mobile (move the top in figure), adjust valve 55 and carry out closing motion, obtain certain secondary pressure thereby carry out pressure regulation to reduce the import volume of fluid.
And, the pressurized error of the adjustment valve 55 that pressure when having considered corresponding to the voltage adjustment characteristic of following a pressure variation, promptly from pressure vessel 12 supply fluids in this pressure vessel 12 reduce gradually.First non-return valve 56 carries out the rightabout on-off action different with adjusting valve 55, and the pressure loss direction of the pressure loss of first non-return valve 56 and adjustment valve 55 is identical and characteristic is opposite substantially.The voltage adjustment characteristic of this adjustment valve 55 is the rising of a relative pressure and characteristic that secondary pressure reduces.Relative therewith, the voltage adjustment characteristic of first non-return valve 56 suppresses secondary pressure when a pressure is low, especially closing valve when pressure is zero forms and is non-return valve, stop fluid to reflux, when rising, opens a pressure, it is the rising of a relative pressure and characteristic that secondary pressure rises is the characteristic opposite with the voltage adjustment characteristic of above-mentioned adjustment valve 55.
Two voltage adjustment characteristics with respect to axle 522 effect in the same direction, thereby the change of the relative pressure of combination voltage adjustment characteristic of opposite two the adjustment valves 55,56 of voltage adjustment characteristic obtains certain secondary pressure.Promptly, supply with and when a pressure is reduced following from the fluid of pressure vessel 12, by acting on the pressure loss of adjusting valve 55, the voltage adjustment characteristic that secondary pressure is risen becomes the characteristic that the pressure loss that acts on first non-return valve 56 reduces secondary pressure, thereby both composite character balances can guarantee to maintain certain secondary pressure by simple structure.
In addition, in released state and not under the user mode, first non-return valve 56 and second non-return valve 57 play a role as non-return valve, can prevent escape of liquid.
Figure 10 and Figure 11 represent second non-return valve 57 ' of another embodiment, second non-return valve 57 of the foregoing description is to be the example that rubber slab constitutes by an elastic plate, but second non-return valve 57 ' of this example by inside be foaming body 57a, upper and lower surface epidermis 57b with non-gas penetration potential elastic plate for example boron material form.This second non-return valve 57 ' reason foaming body 57a constitutes and lightweight, because of epidermis 57b is set, the aeration that does not run through above-below direction, low at the pressure ratio secondary pressure that imports oral-lateral, when secondary pressure is higher, the intercommunicating pore 543 of wall part 542 can be promptly blocked by the pressure of top effect from figure, the action that refluxes can be stably be prevented.
This second non-return valve 57 ' can carry out compression deformation, at the front end of the joint tube portion 533 that is compressed in body housing 53 and import under the state between the upper surface of wall part 542 of parts 54, assembles as illustrated in fig. 10.
Figure 11 represents to import the state of pressure fluid, by pressure from the pressure fluid of intercommunicating pore 543 effect, second non-return valve 57 ' carries out compression deformation, thereby leave and intercommunicating pore 543 is opened wide from the upper surface of wall part 54, the pressure fluid of Liu Ruing is through the periphery of second non-return valve 57 ' thus, flow into interior all sides via the front end breach 534 that engages tube portion 533, and flow into pressure balance chambers 530 via adjusting valve 55.
Below with reference to Figure 12～Figure 14 another embodiment of pressure regulating device of the present invention is described.Connector 2 and pressure vessel 12 are same as the previously described embodiments, omit its explanation in the present embodiment.Figure 12 cuts away about 90 ° scope and the broken section exploded perspective view shown in the exploded with pressure regulating device 7 edges of present embodiment through the circumference around the axis Y at its center, and Figure 13 is with the local amplification view shown in the top amplification of the pressure regulating device 7 of Figure 12.Figure 14 cuts away the broken section amplification stereogram shown in about 90 ° scope and local the amplification with the bottom of the pressure regulating device 7 of the Figure 12 after the assembling along the circumference around the axis Y.
As shown in figure 12, pressure regulating device 7 has casing 70, and this casing 70 has body housing 73, cover case 71 and the cylindrical shape that is installed on the body housing 73 imports parts 74.Body housing 73 and cover case 71 have bellying 73b, 71b respectively, and have identical shaped flange 73a, 71a in periphery.On bellying 73b, be formed with the through hole 73d (Figure 13, Figure 14) that is positioned at the position corresponding with axis Y.Flange 73a, the 71a of body housing 73 and cover case 71 dock mutually, and flange 73a, 71a are by the fastening joints such as (not shown) of screw.
The whole recess 73c that circumferentially is formed with in the flange 73a inboard, interface 70a (Figure 12) upper edge of the flange 73a of body housing 73.Dispose diaphragm 72 in this recess 73c, by the joint of flange 73a, 71a, diaphragm 72 is pushed between two flange 73a, the 71a fixing.By forming this recess 73c, diaphragm 72 is maintained at the fixed position, therefore, is carrying out above-mentioned joint and above-mentioned pushing fixedly the time, and diaphragm 72 is assembled with being curled, can reduce the generation of unfavorable conditions such as escape of liquid.
On the other hand, dispose axle 722 across diaphragm 72 at the opposition side of supporter 721.In addition, at this, refer to the above-below direction among Figure 12～Figure 14 up and down.
Inside surface at the bellying 71b of cover case 71 is formed with protuberance 711 on the position corresponding with teat 721b.The front end of protuberance 711 is a lower surface and the identical even shape that forms of upper surface of supporter 721.Be formed with aperture 711a (Figure 13) with external communications in the central authorities of protuberance 711.The outside is generally atmospheric pressure, and therefore, the space in the bellying 71b maintains atmospheric pressure, and this space becomes atmospheric air chamber 710.
Periphery at the protuberance 711 of the teat 721b of supporter 721 and cover case 71 disposes pressure spring 713.This pressure spring 713 pushes diaphragm 72 downwards with predetermined pressure all the time across supporter 721.When pressure regulating device 7 is in common user mode, between the upper surface of the teat 721b of the lower surface of protuberance 711 and supporter 721, guarantee gapped G (Figure 13).Thus, if the supply pressure of fluid is too high, the axial region 722c of axle 722 described later is pushed upward, the lower surface butt of the upper surface of the teat 721b of supporter 721 and the protuberance 711 of cover case 71, thus can prevent diaphragm 72 excessive deformations.
On cover case 71, be formed with from bellying 71b along the extension 71c (Figure 12) that laterally bloats.Be formed with the conduit 715 that extends to the outside from this extension 71c on this extension 71c, this conduit 715 is formed with escape hole 714.In addition, on cover case 71, be formed with the columniform space 710a (Figure 12) that is communicated with escape hole 714 by next door 71d.On the other hand, on the part of the body housing corresponding 73, be formed with roughly columned space 730a by next door 73d with space 710a.In Figure 12 and Figure 13, the end face 73d ' that can see next door 73d (Figure 13), the other end of next door 73d is positioned on the position relative with this end face 73d ', end face is interactive each other, between constitutes groove 73e (Figure 13, Figure 14).On the body housing 73 adjacent, be formed with the stage portion 730b of roughly ring-type up with space 730a.In addition, on diaphragm 72, be formed with circular opening 72c (Figure 12) corresponding to space 710a, 730a.In space 710a, 730a, the opening 72c that runs through diaphragm 72 disposes the cartridge unit 731 with flange 731a.At this moment, the flange 731a of cartridge unit 731 is arranged on the stage portion 730b.The lengthwise dimension of cartridge unit 731 is defined as leaving the gap between the inner face of lower end and bellying 73b (Figure 13, Figure 14), and formation will be via the path of the direct fluid escape hole 714 of groove 73e.That is, this path constitutes the outlet of the pressure fluid discharge that will be housed in the pressure balance chamber 730 described later.Cartridge unit 731 is for example made by the polyoxy methylene.In addition, in the present embodiment, on cover case 71, form extension 71c, escape hole 714 and conduit 715, but the present invention is not limited thereto, so long as can will be housed in the structure supplied with to outside (for example fuel cell etc.) of fluid in the aftermentioned pressure balance chamber get final product, for example also extending port, escape hole and conduit can be set on body housing 73.
Being formed with the space between the bellying 73b of body housing 73 and axle 722 and diaphragm 72 is pressure balance chamber 730.Leading section at the axial region 722c of the outstanding downwards axle 722 of the through hole 73d that runs through bellying 73b is formed with all slot parts 725 (Figure 13), and is equipped with in week in this slot part 725 and adjusts valve 75.This is adjusted valve 75 and is driven along the vertical direction by diaphragm 72, will block or conducting via the mobile of the fluid between axial region 722c and the through hole 73d, to adjust the hydrodynamic pressure in the pressure balance chamber 730.In addition, as mentioned above, because diaphragm 72 has elasticity, so the axial region 722c that the vibration of the diaphragm 72 that elasticity causes etc. may make axle 522 promptly be equipped with and adjust valve 75 tilts, can make the valve seat of bellying 73b lower surface sustain damage this moment, might cause that pressure control is bad, therefore, the periphery of the flat part 722a of axle 722 is supported obliquely by the next door 73d of body housing 73 and the inner peripheral surface of bellying 73b.Like this, owing to support on distance diaphragm 72 closer inclined position ground, so can further reduce the inclination of a 722c.
In addition, on the promptly relative face of the upper surface of body housing 73 with pressure balance chamber 730, as shown in figure 14, from the inboard outwards on the axial region 722c position relative with described outlet, be provided with for what the fluid via described gap passed through with the form of extending and pass through groove 732 from described gap.Thus, when the pressure of the fluid of supplying with from described pressure vessel 12 hanged down, axle 722 moved downwards because described adjustment valve 75 is opened, so the lower surface of the flat part 722a of axle 722 contacts with the upper surface of body housing 73, can prevent that fluid is difficult to flow.In addition, owing to be arranged on the axial region 722c position relative with described outlet by groove 73, fluid can flow in the wide region of pressure balance chamber 730, so gas is difficult for remaining in the pressure balance chamber 730, can reduce abnormal vibrations (the so-called vibration (chattering) of diaphragm 72, hereinafter referred to as vibration), can improve the action stability of pressure regulating device 7.In addition, be formed as described above in the present embodiment, but also can on the body housing 53 of the pressure regulating device 5 of the foregoing description, have formed this groove that passes through by groove 732.
In addition, the pressure balance chamber 730 of present embodiment is substantially only formed by diaphragm 72 and the mobile space of axle 722 and the stream of fluid.Usually, in the pressure control of compressible fluids such as gas, if because the on-off action of valve or turbulent flow etc. produce the input of the pressure differential with moment, then fluid is easy to vibrate, in order to suppress the vibration of the diaphragm that this vibration causes, pressure balance chamber need be strengthened fully as the impact damper that absorbs described pressure differential, if but this incompressible fluid of liquid for example, then fluid is difficult for causing vibration, therefore, can reduce the volume of pressure balance chamber 730, thereby form above-mentioned pressure balance chamber 730.In addition, the design of pressure balance chamber 730 can suitably be changed according to the fluid that is housed in this pressure balance chamber 730.
In addition, on the bellying 73b of body housing 73, be equipped with the annular wall 73f of the leading section that surrounds axial region 722c downwards.Cardinal extremity periphery at annular wall 73f is formed with endless groove 73f ' (Figure 13), and O shape ring 733 is installed in this groove 73f '.Periphery at annular wall 73f for example is formed with not shown screw thread, can screw togather with importing parts 74.
Importing parts 74 is the parts that are connected with the supply company fitting 3 (with reference to Fig. 1) of described pressure vessel 12, has wall part 742 in the centre of its length direction.On this wall part 742, be formed with the opening 743 of the interlock projection 76c that accommodates stick harness 76 described later.In addition, the inner peripheral surface that surround the inner peripheral surface of the interlock projection 76c that is accommodated, promptly is in wall part 742 belows has more downwards the tapering that then opening diameter is big more (at this because taper ratio is less, so do not show among the figure).Thus, when being connected, described valve system 6 can be inserted sleekly, can improve operability with supply company fitting 3.At this, this tapering is arranged to: when being connected with described supply company fitting 3, and before the control valve 61 of valve system 6 is opened, sealed parts 33 sealings.In addition, the angle that is formed by described inner peripheral surface and wall part 742 is a C face 744.Thus, can reduce the dead angle that imports in the parts 74, can reduce that supply company fitting 3 connects and the leakage of fluid when taking off.In addition, in the present embodiment, as mentioned above, be formed with described tapering and described C face, but also can on the importing parts 54 of the pressure regulating device 5 of the foregoing description, form this tapering and C face.
And, begin to dispose filtrator 78, joint 77, compression helical spring (the following spring that only is called) 79 and stick harness 76 between next door portion 742 and the bellying 73b from the top.
In addition, in the present embodiment, filtrator 78 forms above-mentioned shape, but the present invention is not limited thereto, and for example also can be tabular.In addition, the material of filtrator 78 is identical with the filtrator of the foregoing description 58, omits its explanation.
Under assembled state, the lower end butt of the flange 77d of joint 77 and the annular wall 73f of body housing 73, filtrator 78 are clamped between the upper wall 77a of the downward stage portion 73g of annular wall 73f and joint 77.The top of filtrator 78 forms for the outstanding middle pressure balance chamber 730 ' (Figure 14) of the leading section of the axial region 722c of axle 722.Inside surface at joint 77 is formed with the continuous groove 77e (Figure 13) of above-below direction, and this groove 77e is formed with many in the interior week of joint 77 apart from one another by ground.These grooves 77e is the stream that supplies the pressure fluid process supplied with.
Described stick harness 76 is pin shapes of being made by stainless steel or polyoxy methylene, has discoideus flange 76a near at an upper portion thereof.The upper axis 76b outstanding to the top of flange 76a has the diameter that can be inserted into spring 79 inboards.The lower shaft 76c outstanding to the below of flange 76a is thin more to the lower end of stick harness 76 more.That is, be formed with tapering, form the taper shape.Near the flange 76a of lower shaft 76c, be arranged with O shape ring 761.This lower shaft 76c becomes the interlock projection 76c as linkage part that makes described control valve 61 interlock actions.This interlock projection 76c has the valve 75 of adjustment, is and the axial region 722c separated structures of following diaphragm 72 interlocks, can not be subjected to the power of diaphragm 72 off normals in connecting moves.That is, same as the previously described embodiments, owing to diaphragm 72 separates with interlock projection 76c, thereby can guarantee voltage regulation function, stop supply pressure than setting the high fluid of secondary pressure.
Be assembled in annular wall 73f when going up when importing parts 74, spring 79 and stick harness 76 remain between the wall part 742 of the upper wall 77a of joint 77 and importing parts 74.At this moment, the flange 76a of stick harness 76 is by spring 79 application of force downwards, and O shape ring 761 is pushed between flange 76a and the wall part 742.Be not connected under the state that imports on the parts 74 at supply company fitting 3, these O shape ring 761 application of forces because of spring 79 are in the state of being close to wall part 742 and flange 76a.Thus, can prevent in the pressure regulating device 7 pressure fluid between the opening 743 of the interlock projection 76c of stick harness 76 and wall part 742 to external leaks.This mechanism is the structure that is independent of pressure regulator valve 725, therefore, can not be subjected to the influence of the secondary pressure of fluid and secondary pressure setting etc.
Describe supply company fitting 3 being connected situation about using on the above-mentioned pressure regulating device 7 below with reference to Figure 15.Figure 15 represents to be connected with the cross section of the pressure regulating device 7 of supply company fitting 3.In addition, with the cross section major part is shown among Figure 15.As shown in figure 15, when being installed in supply company fitting 3 on the pressure regulating device 7, stick harness 76 is pushed upward by control valve 61.At this moment, projection 76c separates formation with the axial region 722c that has adjustment valve 75, link with diaphragm 72 because stick harness 76 promptly links, so the power that described pushing produces can not be applied on the diaphragm 72, therefore, can not influence voltage regulation function.
So, to be opened by the opening 743 of the importing parts 74 of O shape ring 761 sealings, pressure fluid passes through the groove 77e and the filtrator 78 of opening 743, joint 77 inboards successively.Under the connection original state of supply company fitting 3, because the hydrodynamic pressure in the pressure balance chamber 730 is lower, so diaphragm 72 is in by pressure spring 713 state of the application of force downwards.Therefore, the adjustment valve 75 that the through hole 73d of body housing 73 is sealed moves to the direction of leaving downwards from through hole 73d, thereby through hole 73d is in the state of removing its sealing.Therefore, through between the described path, filtrator 78, middle pressure balance chamber 730 ', through hole 73d and the axial region 722c that formations stream, the fluid of pressure balance chamber 730 and cartridge unit 731 supplies with to fuel cell from escape hole 714.
Under common user mode, diaphragm 72 is set at: with respect to pressure, for example 900KPa～1MPa of the fluid of being supplied with, making in the pressure balance chamber 730 by pressure spring 713 is predetermined pressure.That is, when the pressure of the fluid of supplying with from supply company fitting 3 is higher than the pressure of the fluid that should supply with, overcome the application of force of pressure spring 713, the fluid in the pressure balance chamber 730 pushes diaphragm 72 upward.The result is, the axial region 722c of axle 722 is moved upward, and the through hole 73d that adjusts 75 pairs of body housings 73 of valve seals, and stops pressure fluid to continue inflow to pressure balance chamber 730 in.Being applied to pressure on the diaphragm 72 from the pressurized stream side not only has pressure in the pressure balance chamber 730, is applied to the power on the adjustment valve 75 in middle pressure balance chamber 730 ' with ining addition.That is, a pressure in the middle pressure balance chamber of the projected area X of pressure regulator valve 730 ' is applied to be adjusted on the valve 75, therefore, because the pressure of above-mentioned pressure fluid adjusts valve 75 and close, adjusts valve 75 and imbeds in the valve seat and be out of shape.During pressure step-down in pressure balance chamber 730, because the application of force of pressure spring 713, the axial region 722c of axle 722 descends and through hole 73d is opened, and pressure fluid can flow in the pressure balance chamber 730 again.
Like this, diaphragm 72 is understood the change of relative hydrodynamic pressure and is constantly moved up and down.But this amount of movement that moves up and down is minimum, for example be about 0.3mm, therefore, described clearance G, is that size between the lower surface of protuberance 711 of the upper surface of teat 721b of supporter 721 and cover case 71 is maintained necessarily substantially.In addition, under the state that pressure fluid is flowing, demonstrate and adjust the form that valve 75 contacts with body housing 73, but in fact, between adjustment valve 75 and body housing 73, have extremely small gap, can pass through for pressure fluid.
