Below, with reference to drawing explanation one embodiment of the present of invention.
In addition, in such structure, the pressure of locating by the axle center that is located at piston 8 injects path 41, fluid pressure injection in the space 13 corresponding with each piston 8 is gone in the pressure depression 11 of corresponding the 2nd hydrostatic support 9, simultaneously, by running through fluid passage 42a, 42b and the 42c of above-mentioned torque ring 2, again the fluid pressure injection in this pressure depression 11 is gone in pressure depression 7a, the 7b and 7c of corresponding the 1st hydrostatic support 3.And, above-mentioned two hydrostatic supports 3 and 9 direction and area, design to such an extent that make the caused caused power equal and opposite in direction that acts on the torque ring 2 of hydrostatic pressure that acts on the power on the torque ring 2 and inject the 2nd hydrostatic support 9 of hydrostatic pressure that injects the 1st hydrostatic support 3, direction is opposite.In addition, the area of above-mentioned the 2nd hydrostatic support 9 also designs to such an extent that make the caused power that acts on the piston 8 of hydrostatic pressure of injecting this hydrostatic support 9, cancels out each other with the caused power that acts on the piston 8 of hydrostatic pressure in the space 13.The 3rd hydrostatic support 26(36) area, design make inject this hydrostatic support 26(36) the caused power that acts on the cylinder sleeve 15 of static pressure, with corresponding regional A(B) in space 13 in the caused power that act on the casing 1 of hydrostatic pressure cancel out each other.The 4th hydrostatic support 28(38) and this hydrostatic support 28(38) the inclined-plane 14b(14c at place) the tilt angle, design make inject this hydrostatic support 28(38) the caused power that acts on the pivot 14 of hydrostatic pressure, and inject above-mentioned inclined-plane 14b(14c) the regional A(B on opposite) the 3rd hydrostatic support 26(36) the caused power that acts on the pivot 14 of hydrostatic pressure cancel out each other.
In addition, the 43rd, seal washer, the 44th, be used for the supporting of auxiliary supporting rotating shaft.The 45th, break is used for making cylinder sleeve 15 to stop pivot 14,46th, and permanent magnet is used for the internal surface of pivot 14 to bonnet 1b attracted, and bonnet 1b constitutes the part of casing 1.
In such hydrostatic profile fluid energy conversion device, for the supporting part pivot 14 that makes above-mentioned torque ring 2 moves along the direction vertical with axis of rotation, more such mechanisms below also having.At first, with casing 1 on the matrix 14a of the chimeric pivot 14 of groove 19 on, from being processed into depression 51 along the direction vertical with axis of rotation with a end that it vertically overlaps, and spring 52 is contained between the bottom surface 51a and casing 1 internal surface of these depression 51 inside, rely on the pushing force of spring 52 that pivot 14 is moved to above-mentioned eccentric position+n.In addition, also be provided with fluid type mechanism 53,53 pairs of pivots of this fluid type mechanism 14 produce the synergistic power of pushing force with spring 52.This fluid type mechanism 53 is made of cylinder 55 and equalizing piston 56, cylinder 55 constitutes the injection syringe 54 that working fluid is injected inside, equalizing piston 56 is entrenched togather with cylinder 55, can be free to slide, near above-mentioned depression 51 places cylinder 55 is being assemblied in the installation hole 57 on the casing 1 by seal washer 58, sealing part 59 is withstood in its outside, is fixed on the casing 1.In addition, the front end 56a of equalizing piston 56 contacts with the bottom surface 51a of above-mentioned depression 51 inside.And above-mentioned spring 52 is assemblied between the basic end face of the back side of equalizing piston front end 56a of fluid type mechanism 53 and piston 55, by equalizing piston 56, pushing force is affacted on the pivot 14.In addition, the high-pressure liquid that this fluid type mechanism 53 can discharge transducer or suck is induced in the injection syringe 54, and can become support force to the pushing force of spring 52 and affact on the pivot 14.That is to say, in an embodiment, have by the passage 24 that runs through pivot, the hydrodynamic pressure loop that fluid passage 61 and fluid passage 62 constitute, at first, can be communicated with stream socket 25 as an end of the high-pressure liquid gateway of transducer on the passage 24, fluid passage 61 is the branches of running through the passage 24 of pivot, and its opening is on the bottom surface 51a of the depression inside that closely contacts with the front end 56a of equalizing piston, and depression is on pivot 14, fluid passage 62 passes the axle center of equalizing piston 56, and its an end opening place is communicated with the opening of above-mentioned fluid passage 61, the opening of the other end is on above-mentioned injection syringe 54, rely on such mechanism, can make the pressure of high-pressure liquid constantly pass to injection syringe 54.In other words, this fluid type mechanism 53 relies on the high pressure fluid of injection and the power support pivot 14 that the cylinder sectional area multiplies each other and obtains.With being communicated with on the corresponding equalizing piston front end 56a of position of fluid passage 61 and 62, assembling seal washer 63, prevent that working fluid from leaking on surface of contact.In addition, on the inner base end face of cylinder 55, assembling the adjustable bolt 64 of advancing and retreat, when in the chimeric equalizing piston 56 indentation cylinders, that is when the pushing force of pivot 14 resistance springs 52 when the other end moves, run into after the lower end surface of equalizing piston 56, bolt 64 can stop pivot 14 to continue to move.That is to say that the effect of bolt 64 is limited in certain value to the amount of movement of pivot 14, particularly, is exactly to make pivot 14 from the axle center m of casing 1 distance of mobile D only in the present embodiment, has arrived eccentric position-n place, just stops to move.
Secondly, in this enegrgy converter, in order to make pivot 14 other directions that is to differ oppositely moving of 180 degree, has the fluid type transmission device 66 that utilizes the pressure compensation mechanism in the transducer and work with the pushing of spring 52 and fluid type mechanism 53 and support direction.That is to say, the back side of depression 51 promptly with casing 1 on the end face of the pivot matrix 14a that is entrenched togather of groove 19 on, have vertical with axis of rotation and with depression 51 opposed depressions 67, in this depression 67, the injection syringe 68 of working fluid is injected in formation to inside, simultaneously, spring 71 between the step 69b by being contained in its inner base end and the bottom surface 67a of depression 67 inside, its basic end face is closely contacted with the internal surface of casing 1, and can be free to slide the cylinder 69 chimeric internal surfaces of this depression 67 relatively.Seal washer 72 by means of being installed on the cylinder end face 69a that contacts with the internal surface of casing 1 prevents that working fluid from leaking on surface of contact.
In addition, by mounting hole 73, pivotal support bar 74 from casing 1 outside be assemblied in pivot 14 on the hollow position of the cylinder 69 that is entrenched togather of depression 67, its front end 74a closely contacts with the bottom surface 76a of depression 67 inside.The head 74a of strut 74 gives prominence to the outside at casing 1, between the outer surface of surface and casing 1 suitable spring 75 is housed within it, under this state, this head 74a is entrenched togather with the bearing cap 76 that is fixed on the casing 1, and, by means of the pin that locks bolt 77 that is installed in its top, can adjust the length that its head 74a gives prominence to from cylinder 69.That is to say that the effect of pivotal support bar 74 is restriction pivots 14 of being subjected to spring 52 pushing the moving an of direction, particularly, in the present embodiment, make pivot 14 from the axle center m of casing 1 distance of mobile D only exactly, arrived eccentric position+n place, just stop to move.So this usefulness decides the flowing type transmission device 66 of mobile position to have the hydrodynamic pressure loop, this hydrodynamic pressure loop is induced injection syringe 68 in the suction casig 69 to the high-pressure liquid of enegrgy converter by pressure-compensated valve.That is to say, this hydrodynamic pressure loop is by the passage 24 that runs through pivot, among fluid passage 81(the 1st figure, simply represent with dotted line), fluid passage 83, fluid passage 84, injection syringe 68 and fluid passage 85 constitute, as previously mentioned, at first, can be communicated with stream socket 25 as an end of the high-pressure liquid gateway of transducer on the passage 24, fluid passage 81 is the branches of running through the passage 24 of pivot, it is the passage 82 on the bonnet 1b of working fluid injection casing 1, fluid passage 83 is communicated with the fluid passage 92 in the matrix 91 in this passage 82 and the pressure compensation mechanism, and matrix 91 closely is assemblied on the bonnet 1b of casing 1, fluid passage 84 is induced to casing 1 to working fluid on one side from the fluid passage 92 in the matrix by pressure-compensated valve 93, one end of injection syringe 68 is communicated with fluid passage 84, the other end is in said cylinder 69, open communication on mounting hole 73 sidewalls of fluid passage 85 and casing 1, pivotal support bar 74 passes this mounting hole 73.In addition, the pressure-compensated valve 93 in the above-mentioned matrix 91 is entrenched in the above-mentioned fluid passage 92, can be free to slide, and constantly pushes and support spool boss 94 according to specified working pressure.Particularly, in fluid passage 92, spool boss 94 assembles to such an extent that make its flange slip surface stride across the aperture position of fluid passage 84 fully, simultaneously, in the bigger supported hole 95 of the mobile terminal extend inside diameter of spool boss 94, supported hole 95 break-through fluid passages 84, and, in the push plate 96 that is enclosed within its head and be installed in locking of supported hole 95 the other ends and be equipped with spring 98 between the bolt 97.Adjust stroke by means of the pin that locks bolt 97, can change the pushing force of spring 98.And, the pushing force that surpasses spring 98 when the high pressure fluid of the transducer that passes over from fluid passage 83 is that the setting of pressure-compensated valve 93 is when pressing, spool boss 94 forward end a little slides a bit, at this moment, spool boss 94 has just been removed the blockade of convection cell path 84, this fluid passage 84 just is communicated with fluid passage 92, therefore, can inject the fluid type transmission device 66 that is used for changing the mobile position to high-pressure liquid, in addition, undoubtedly, when high pressure fluid is lower than the setting pressure, spool boss 94 resets, and supplies with high-pressure liquid so cut off to transmission device 66.86,87 and 88 is fluid passages, is used for respectively the gutter on the working fluid injection casing inner surface that returns from transmission assembling 66.In addition, the 99th, locking device makes the position of spool boss 94 hold resets.
Yet, by such pressure-compensated valve 93 working fluid when the high voltage terminal of transducer injects above-mentioned fluid type transmission device 66, hydrodynamic pressure surpasses the elastic force of above-mentioned spring 52 and the active force of above-mentioned equalizing piston 56, and pivot 14 is moved to the other end.Here, this transmission device 66 affacts the driving force on the pivot 14, and the injection syringe that equals working fluid is the pressure that the area of the bottom surface 67a of depression 67 inside multiply by the high-pressure liquid of injection, and this power makes pivot 14 move to eccentric position-n.Therefore, to overcome the active force of pushing force on opposite big for the driving force ratio equalizing piston 56 of this transmission device 66 outputs.In other words, design the elasticity of spring 52 according to the active force of fluid type transmission device 66 and equalizing piston 56, when making it to satisfy setting that high pressure fluid when transducer departs from pressure-compensated valve 93 and pressing to the direction variation of increase, pivot 14 can move sleekly.And, when the setting that the high pressure fluid that the elasticity of spring 52 also should design proper transducer reaches pressure-compensated valve 93 is pressed, in the stage that fluid type transmission device 66 just will drive, the active force of spring 52 and equalizing piston 56 also is a bit larger tham this driving force, improve a bit if make to set to press a little, so, it should be able to make pivot 14 move to the other end immediately.As mentioned above, the effect of the screw 64 in the fluid type mechanism 53 is restriction pivot 14 displacement amounts when moving.
Below, the effect of illustrated embodiment is described.
The basic role of this converter body part is opened the same of clear and the introduction of 58-77178 communique with the spy.That is to say, if the axle center of pivot 14 is set in+position of n, when torque ring 2 under external force when arrow R direction is rotated, so, high-pressure liquid is just from 21 ejections of the 1st fluid flow circuit, so, play pump.Otherwise, if the axle center of pivot 14 is set in-position of n, when supplying with high-pressure liquids, will produces and make the couple of torque ring 2 along the rotation of arrow S direction by the space 13 of above-mentioned the 1st fluid flow circuit 21 in the 1st zone, so, play motor.And under the state as pump or motor use, the running shaft 6 of transducer rotates in a certain direction according to the shaft core position of appointment separately.
Secondly, effect when transducer changed the volume use be described.
Suppose transducer as hydraulic power, be applied to fluid and press the hydraulic machine of drive-type, axle center at diagram pivot 14 is positioned at+the eccentric state of n under, when using as pump, this pump outwards sprays the 1st fluid flow circuit 21 of the close high voltage terminal of flow that offset determined.Yet, when the load pressure of high voltage terminal promptly sprays when pressing the setting that reaches appointment to press, so, the pressure-compensated valve 93 that is installed on the hydrodynamic pressure loop of injecting high-pressure liquid is just opened, so, fluid type transmission device 66 is just induced into injection syringe 68 to high-pressure liquid, and, fluid type transmission device 66 should be set the cambic spray volume that adapts with ejection pressure, when being pressed with the tendency that a bit increases with this fluid of box lunch, pivot 14 is moved, when pressure further rises, fluid type transmission device 66 just overcomes the pushing force of the spring 52 and the equalizing piston 56 on opposite, makes the axis deviation of pivot 14 promptly depart from axis of rotation by eccentric position-n that above-mentioned limiting means determined and moves to the other end.And when pivot 14 was finished it mobile, transducer just became from the pump of the 1st fluid flow circuit 21 ejection minus flows, that is to say, injects after the high-pressure liquid, and running is automatically switched, and becomes along the motor of same direction rotation.The ejection flow of transducer of such volume-variation and the relation table between the load pressure take place be shown in the 5th figure.As shown in the drawing, this transducer and the pump with pressure compensation before are relatively, and be as a and b, corresponding with ejection pressure, just control the pressure difference of spray volume, set and press if surpass this, so, just and C such, basically keep-up pressure certain (this pressure is equivalent to the setting of pressure-compensated valve and presses), little by little increase the influx of high voltage terminal, before reaching the influx of appointment, turn round as motor with the fluid energy that high-pressure liquid was had.Therefore, wall as, if the running shaft b of unidirectional rotary generator and this transducer is coupled together, so, when the motor as above-mentioned C and d place uses, can reclaim fluid energy, rely on this energy recovery function, can be used as energy-saving converter and work.
More than Shuo Ming embodiment is special relevant with the 2nd invention of the present invention, rely on the pushing force of spring 52 and the driving force of equalizing piston 56 to make pivot 14 move and it is supported, come from the principle, the present invention uses equalizing piston 56 simultaneously, that is to say, only rely on the pushing force of spring 52 that pivot is moved and it is supported, the driving force that also can reach the fluid type transmission device 66 that this pushing force and displacement use balances each other, therefore, the present invention is being included in the 1st invention by such device that structure constituted.In addition, as above-mentioned embodiment introduced, when enforcement was of the present invention, it was favourable that equalizing piston 56 is set.About this point, can be by following situation explanation.Hydrostatic profile transducer for the foregoing description, when the pivot axis it move to+when the eccentric position of n uses as pump, on the principle, affact supporting part and be the mutual balance of power on the pivot 14, displacement force is inoperative, but, in fact, because the compressibility of working fluid, the variation in pressure in each space 13 lags behind the general time, so, the unbalanced force that pivot 14 is withdrawn into the neutral position is worked.Therefore, if only support, so with above-mentioned spring 52, this spring 52 must can produce sizable pushing force, yet, in order to produce recited above moving, need very long stroke, so the design of spring 52 is very difficult (for example: may surpass the thread breakage stress that spring coil is allowed, if increase the number of turns, seat phenomenon in the wrong or the like takes place again easily), and, assemble or during demolition, also difficulty and dangerous relatively.Yet,, so, just can address these problems, and make spring 52 have Ideal Characteristics, and then can make this transducer have stable volume-variation if use equalizing piston 56 to come supporting pivot 14.
In addition, for transducer of the present invention, undoubtedly, the structure of finishing the body portion of pumping function or motor function has more than the situation that is limited to the foregoing description, for example, also can be common actinoid reciprocating pump or motor or the like.
Because transducer of the present invention is a structure recited above, so, can make the sense of rotation of running shaft keep certain, can automatically switch operating condition with the pressure of high voltage terminal again, the function that pump is not only arranged also has the function of motor, therefore, can bring into play high efficiency energy recovery function, the transformation of energy with usual pressure compensate function is returned then and can not be reached.
