Rotary piston machine

Affiliated technical field

The present invention relates to the rotary-piston machine field that solid mechanical energy and fluid can be changed mutually.

Background technique

In the prior art, the effect of water turbine and steam turbine is exactly fluid can be converted to mechanical energy (moment of torsion of directed rotation), this point prior art realized and efficient very high.But for low water head, low discharge, low pressure or slow-revving environment, water turbine and turbine work efficient just will reduce greatly; In the prior art, the effect of water pump and blower fan is converted to the fluid energy with mechanical energy exactly, and this point prior art also realizes, but for slow-revving environment, the working efficiency of water pump and blower fan just will reduce greatly.Its reason be since these machineries in each all process of rotation, casing (cylinder body) and blade (piston) do not cooperatively interact and form static piston effect, casing and blade do not produce the directed piston effect that rotates in other words; The size variation in empty cross section in casing does not form off and on, blade does not have the sectional area size on its running orbit of periodic variation yet.This phenomenon causes some inferior fluids can not get fully and effectively utilizes, as the thermal expansion generating of solar energy, the current generating of low water head, and produce with live in overbottom pressure utilization etc. in the fluid system; This phenomenon also make some slow-revving mechanical energy can not be fully be converted to the fluid energy effectively.

In known four-stroke reciprocating piston explosive motor, piston and connecting rod comprise valve, rocking arm and tappet etc., all reciprocating inevitably, because these parts all have certain quality, these parts direction of momentum in movement process is opposite in other words, so reduced efficiency of engine; In the working procedure of known four-stroke reciprocating piston explosive motor, the top of reciprocating piston and cylinder are engaged in finishes a few thing, and the bottom of reciprocating piston does not have substantial performance, and this also greatly reduces the efficient of volume mass with the ratio of output power of motor; In the working procedure of known four-stroke reciprocating piston explosive motor, motor also must drive distribution device and turn round simultaneously, so consumed the part power of motor, complicated distribution device has also increased the weight and the manufacture cost of motor.

In rotary piston machine in the past, comprise oil hydraulic pump and oil hydraulic motor, how to produce the volume-variation in the rotary course as follows: the scraper plate piston of radial expansion on elliptical cylinder-shape cylinder body and the rotor; The two cylindrical crossing cylinder bodies and the rotor of two external gears engagement; Flexible scraper plate piston on cylinder block and oval or many prismatics rotor and the cylinder body; The radially flexible scraper plate piston or the gear piston of rotor upper planet rotation on the concavo-convex cylinder body of internal gear shape and the rotor; Rotary-piston is positioned at two planar ends of cylindrical cylinder; Cylinder block and round differential together rotor; Cylinder block and eccentric rotor rotated etc.Since these structures all respectively with exist to some extent that complex structure, complex process, cost of production height, volume are big with quality, relative too little, the inefficiency of the ratio of swept volume and machine volume, speed range is narrow and phenomenon such as poor stability, so be of limited application.

In Fig. 3 and Fig. 4, an end of main shaft 4 has tie-plate 3, and the profile of tie-plate 3 is cylindrical, is piston shelf 2 on the excircle of tie-plate 3, and piston shelf 2 and tie-plate 3 and main shaft 4 are on same circle central axis, and disjunctor rotates synchronously; A tie-plate inner chamber 5 is arranged in the inside of tie-plate 3.There are a plurality of piston axis holes 7 center between two disks of piston shelf 2, and piston axis hole 7 becomes radiation-like on piston shelf 2, and piston axis hole 7 cuts across the another direct puncture in piston hole 6 backs and leads in the tie-plate inner chamber 5.Plate shape piston 1 is supported in the piston hole 6 by piston shaft 8 and piston axis hole 7, the transverse arm 11 of the piston shaft 8 lower ends spring 12 of having risen to the bait, and the other end of spring 12 is hooked on the tie-plate inner chamber 5.Spring 12 makes piston shaft 8 have torque, torque on the piston shaft 8 forces the left hand edge 9 and the mode of right hand edge 10 by sliding friction of plate shape piston 1, contact with rear-bank rotor housing 14 with front-bank rotor housing 13 respectively, and keep certain contact pressure, also make plate shape piston 1 have the ability of wear automatic-compensation simultaneously.

In the process of main shaft 4 rotation, the left hand edge 9 of plate shape piston 1 and the mode of right hand edge 10 by sliding friction contact with rear-bank rotor housing 14 with front-bank rotor housing 13 respectively, when piston space 19 places that rotate to fluted shape, and the pendulum angle increase of plate shape piston 1; When rotating to the end of piston space 19, the pendulum angle of plate shape piston 1 reduces.

In another embodiment of spring loaded plate shape piston 1 swing, the lower end of piston shaft 8 does not have transverse arm 11, spring directly is enclosed within on the piston shaft 8, on the piston shaft 8 radial hole is arranged, one end of spring is inserted in this hole, the other end of spring rides on the piston shelf 2, spring makes piston shaft 8 have the torque of relative piston shelf 2, this torque forces the left hand edge 9 and the mode of right hand edge 10 by sliding friction of plate shape piston 1, contact with rear-bank rotor housing 14 with front-bank rotor housing 13 respectively, and keep certain contact pressure, also make plate shape piston 1 have the ability of wear automatic-compensation.

In Fig. 5, the swing of plate shape piston 1 is opened and is closed up by it and realizes, plate shape piston 1 is made up of with right panel 37 left plate 36.The right part of left side plate 36 has a through hole perpendicular to the plate face, the left part of right panel 37 has a through hole perpendicular to the plate face is also arranged, the through hole of left side plate 36 and the through hole of right panel 37 are enclosed within on the same piston shaft 8 with the cross modal of hinge, and left plate 36 can both rotate around piston shaft 8 with right panel 37.Middle part at piston shaft 8 also is with spring 38, and two elasticity arms of spring 38 are pressed in respectively on left plate 36 and the right panel 37, and spring 38 forces left plate 36 to have outside open moment of elasticity with right panel 37.Piston shaft 8 and piston shelf 2 disjunctors, and with main shaft 4 rotations.

In Fig. 7, contact for making plate shape piston 1 with cylinder body friction, move in the mode of maintenance certain interval, the swing of plate shape piston 1 is that the guiding by the annular groove on the cylinder body realizes.Plate shape piston 1 is synchronous with piston shaft 8 disjunctors, and an end of piston shaft 8 has a transverse arm 11, and an end of transverse arm 11 has a chute bolt 40.The parallel axes of the axis of chute bolt 40 and piston shaft 8, the axis of the axis of chute bolt 40 and piston shaft 8 has certain distance; Piston shaft 8 is positioned on the last plane of transverse arm 11, and chute bolt 40 is positioned on the lower plane of transverse arm 11.Be arranged in the tie-plate inner chamber with the cylindrical body 41 of cylinder body disjunctor, and rotate relative to piston shelf 2.Chute 42 is arranged on the circumferential surface of cylindrical body 41, and the track two ends of chute 42 on cylindrical body 41 link to each other.The axis shaft of the relative cylindrical body 41 of the track of chute 42 on cylindrical body 41 is to variation, and forms curve and straight line on the circumferential surface of cylindrical body 41, and the width of chute 42 and the degree of depth can be held chute bolt 40.Chute bolt 40 is inserted in gliding motility in the chute 42, changes the deflection angle of plate shape piston 1 with this.

Chute 42 can be located in the tie-plate inner chamber 5, also can be located on the annular disk of front-bank rotor housing 13 and rear-bank rotor housing 14.On the planar annular in front-bank rotor housing 13 and the piston shelf space 17 of rear-bank rotor housing 14, axially have the chute of ring, the degree of depth of chute changes at axial wave, and forms the Lang Feng and the wave end; On same central angle, the Lang Feng of the chute on the relative piston shelf 2, the chute on the front-bank rotor housing 13 and rear-bank rotor housing 14 is just in time opposite with the unrestrained end.End at piston shaft 8 has transverse arm, and transverse arm can be swung at two disk ends of piston shelf 2, and protrudes from two disk ends of piston shelf 2 respectively; The part that transverse arm protrudes from piston shelf 2 stretches into chute wave on the cylinder body at the end.

In Fig. 8, plate shape piston 1 is supported in the piston axis hole 7 on the piston shelf 2 by piston shaft 8, and plate shape piston 1 is with piston shaft 8 disjunctors and can rotate relative to piston shelf 2, and an end of piston shaft 8 stretches in the tie-plate inner chamber 5.One end of each piston shaft 8 all has a taper moving gear 43, taper moving gear 43 in tie-plate inner chamber 5, the axis coaxle of the axis of taper moving gear 43 and piston shaft 8, taper moving gear 43 rotates synchronously with piston shaft 8.The left part of a quiet gear 44 of taper is fixed on the front-bank rotor housing 13, and the quiet gear 44 of taper stretches in the tie-plate inner chamber 5, and meshes the axis of the quiet gear 44 of taper and the axis coaxle of main shaft 4 with a plurality of taper moving gears 43; The axis of the quiet gear 44 of taper and the axis normal of a plurality of taper moving gears 43; The quiet gear 44 of taper rotates relative to piston shelf 2.

When main shaft 4 rotated with piston shelf 2, the quiet gear 44 of taper was stirred taper moving gear 43 and is rotated, and taper moving gear 43 drives plate shape piston 1 again and rotates on piston shelf 2.Along with the rotation angle difference of main shaft 4 in each week, the sectional area of the rotating locus of plate shape piston 1 on piston shelf 2 is also being done periodic the variation, the also corresponding this variation of piston space 19 on the cylinder body, plate shape piston 1 passes the narrow zone of cylinder body with relatively little area, and plate shape piston 1 passes the spacious zone of cylinder body again with big relatively area.So far, main shaft 4 rotatablely moves with piston shelf 2 orientations, and plate shape piston 1 orientation on piston shelf 2 rotatablely moves and relative piston shelf 2 orientations rotatablely move, and has realized the function of rotary piston machine with this.The quiet gear 44 of taper can also be an intermittent gear with taper moving gear 43, promptly after main shaft 4 has rotated several angle, the quiet gear 44 of taper is just stirred taper moving gear 43 and is turned an angle, pause again then certain central angle, the so just endurance of energy control panel shape piston 1 deflection angle in the cylinder body one stroke.

Rotary piston internal combustion engine.In Fig. 9, the piston space 19 that is distributed in the groove shaped on front-bank rotor housing 13 and the rear-bank rotor housing 14 is even number, and first piston space 19 on the sense of rotation is that 25, the second piston spaces 19 of air inlet compression groove are acting air vents 26.The starting point of the air inlet compression groove 25 on the sense of rotation has one to enter hole 20, the starting point of the acting air vent 26 on the sense of rotation has a spark plug 21, the position of spark plug 21 also can be an oil nozzle, and the end end of acting air vent 26 has a tap hole 22.

In Figure 10, all there is a gas collection storehouse 23 at the rear portion of each piston hole 6 of the piston shelf 2 on the dextrorotation veer, and gas collection storehouse 23 communicates with the rear portion of piston hole 6, and gas collection storehouse 23 occupies the part entity of piston shelf 2, and connects the last lower plane of piston shelf 2.Each gas collection storehouse 23 all communicates with a back piston hole 6 on the sense of rotation by a transfer port 24, and transfer port 24 is in the entity of piston shelf 2.

The working principle of rotary piston internal combustion engine is: the piston shaft 8 of plate shape piston 1 is subjected to the effect of spring 12, cause the left hand edge 9 of plate shape piston 1 to contact with rear-bank rotor housing 14 with front-bank rotor housing 13 respectively, and keep certain elastic contact pressure with the mode of right hand edge 10 by sliding friction.Plate shape piston 1 moves under the drive of piston shelf 2 clockwise; In the time of in turning to air inlet compression groove 25, the left hand edge 9 and the right hand edge 10 of plate shape piston 1 guided and slip in air inlet compression groove 25 by the effect of spring and the shape of air inlet compression groove 25, the plate shape piston 1 isolated space that has sealed the air inlet compression groove 25 of its traffic direction front end and back end, cause the space in plate shape piston 1 the place ahead to be compressed, the space at rear is extended and by entering hole 20 inspiration mixed gass.At each plate shape piston 1 during by air inlet compression groove 25, its place ahead is always at the mixed gas of the last plate shape piston of compression 1 inspiration, and its rear is always at the new mixed gas of inspiration.Back one plate shape piston 1 is compressed in the gas collection storehouse 23 of last plate shape piston 1 afterbody by the mixed gas of transfer port 24 with 1 inspiration of last plate shape piston.When each plate shape piston 1 entered into piston shelf space 17, the mixed gas in its place ahead had been compressed to by transfer port 24 in the gas collection storehouse 23 of last plate shape piston 1, and the plate shape piston 1 that this moment, transfer port 24 was entered into piston shelf space 17 is closed.Its left hand edge 9 of plate shape piston 1 usefulness or right hand edge 10 are blocked the transfer port 24 in the last gas collection storehouse 23 of leading on the piston hole 6.When the plate shape piston 1 that has compressed mixed gas in each afterbody gas collection storehouse 23 runs in the acting air vent 26, spark plug 21 igniting of corresponding mechanism control, mixed gas detonation in the gas collection storehouse 23 is expanded, and slurcocks shape piston 1 slides in the air vent 26 in acting, and plate shape piston 1 drives piston shelfs 2 by piston shaft 8 and main shaft 4 rotates.So far, when each plate shape piston 1 ran in the acting air vent 26, its rear was always at ignition-powering, and its place ahead is always at the waste gas of discharging last plate shape piston 1 by tap hole 22.So just realized the directed planet rotation of piston,---compression---acting---work of exhaust has realized the function of rotary piston internal combustion engine with this and each piston is all carrying out air inlet.

With regard to the rotary piston internal combustion engine of two cylinders (two piston spaces), main shaft whenever revolves to turn 90 degrees just has a piston at ignition-powering, and the four-ignition acting is just arranged in one week of main axis rotation.This motor is except that the mode to-and-fro motion of plate shape piston 1 with swing, and other parts all are to move in the mode of orientation rotation.Change piston space 19 and the arc length ratio of piston shelf space 17 on circumference, just can change the working stroke length of motor.Increase the quantity of piston space 19 on circumference and the diameter of cylinder body, just can increase the acting number of times and the output torque in one week of main axis rotation.By the mixed gas of back one Piston Compression, when entering the gas collection storehouse 23 of last piston, can in transfer port 24, quicken and be mixed fully and vaporization by transfer port 24, this helps the abundant burning of mixed gas.

Because when each plate shape piston 1 is arranged in air inlet compression groove 25 or acting air vent 26, as long as there is the gas pressure intensity that is higher than its place ahead at the rear of this plate shape piston 1 traffic direction, plate shape piston 1 just can travel forward under the promotion of gas pressure intensity, so motor can be started by pressurized gas, and does not need to be started by electric motor.The pressurized gas that will be stored in advance by a cover valve switching mechanism feeds the starting point of air inlet compression groove 25 and acting air vent 26, pressurized gas just can slurcocks shape piston 1 and piston shelf 2 rotate, piston shelf 2 has played the momentum storage effect of Flywheel disc again.After piston shelf 2 reaches certain rotating speed, piston shelf 2 inertia rotations, this moment closes compression gas transfer passage and recover air inlet and the function of igniting, just energy starting operation of motor.

Because plate shape piston 1 is to contact with the piston space 19 of groove shaped on front-bank rotor housing 13 and the rear-bank rotor housing 14 respectively by its left hand edge 9 and right hand edge 10, so be positioned at the piston space 19 on front-bank rotor housing 13 and the rear-bank rotor housing 14, just differ certain center of circle angle at its starting point and end end.Differ the size of center of circle angle, and the left hand edge 9 of plate shape piston 1 and the distance dependent between the right hand edge 10.

Front-bank rotor housing 13 is connected as a whole by bolt at its round edge place with rear-bank rotor housing 14.The elastic mat that an annular is arranged on the junction surface between front-bank rotor housing 13 and the rear-bank rotor housing 14 still also has sealing effect when its objective is the variable in distance between current cylinder body 13 and the rear-bank rotor housing 14.Be with elastic washer on the bolt that connects front-bank rotor housing 13 and rear-bank rotor housing 14, its objective is to allow can have certain flexible distance between front-bank rotor housing 13 and the rear-bank rotor housing 14, so that keep the clamping degree of front-bank rotor housing 13 and 14 pairs of piston shelfs 2 of rear-bank rotor housing.

Because the deflection angle of plate shape piston 1 on piston shelf 2 is by the decision of the degree of depth of the piston space on the cylinder body 19, so distance between the degree of depth of two piston spaces 19 on front-bank rotor housing 13 and the rear-bank rotor housing 14, must be less than the left hand edge 9 of plate shape piston 1 and the distance between the right hand edge 10, too big with the pendulum angle that prevents plate shape piston 1.

In Figure 10, for each friction position that makes motor obtains oil lubricating, tie-plate inner chamber 5 is oil storage tanks, and the machine oil in the tie-plate inner chamber 5 is transported to each friction position by centrifugal force.A plurality of blind holes 30 are arranged in the entity of piston shelf 2, and an end of blind hole 30 leads in the tie-plate inner chamber 5, and the other end of blind hole 30 communicates with the lubrication hole 31 that connects 2 two disks of piston shelf.Some oilhole break-through tie-plate inner chambers 5 communicate with the outer peripheral surface of tie-plate 3.Machine oil in the tie-plate inner chamber 5 is flowed out by lubrication hole 31 through blind hole 30 by centrifugal action, and lubricated front and back cylinder body and piston shelf 2 comprise the attrition surface of tie-plate 3.The lubricating oil that flows out in the tie-plate inner chamber 5, the attrition surface of cylinder body and piston shelf 2 can form the sealing aspect again before and after can lubricating between front and back cylinder body and piston shelf 2.

In Figure 11, for making piston shaft 8 in the operation process of motor, obtain oil lubricating, there is blind hole 27 from bottom to top the axis centre position of piston shaft 8, oil outlet 28 radially passes the top of piston shaft 8 and communicates with blind hole 27 on its axis, and oil outlet 28 forms two oil outlets on the circumferential surface on piston shaft 8 tops; Another oil outlet 29 radially passes the bottom of piston shaft 8 and communicates with blind hole 27 on its axis, and oil outlet 29 forms two oil outlets on the circumferential surface of piston shaft 8 bottoms.Lubricating oil in the tie-plate inner chamber 5 is pressed into by rotary centrifugal force in the blind hole 27 of piston shaft 8 axis, again by oil outlet 28 and oil outlet 29 lube pistons axles 8 and piston axis hole 7.The left hand edge 9 of plate shape piston 1 is scraped the machine oil of getting on the piston shelf space 17 with right hand edge 10, and carries it into the attrition surface of lube plate shape piston and piston space in the piston space 19.

In Figure 12, a disk end empty in the tie-plate inner chamber 5 seals, and the round tube hole 32 of a minor diameter is arranged on another disk end.Machine oil between front and back cylinder body and piston shelf 2, by spreading to the big circumference position small circumference position, and 17 places, piston shelf space on the circumferential surface of piston shelf 2 compile owing to be subjected to action of centrifugal force, and have certain pressure.Front-bank rotor housing respectively has an oilhole to communicate with the largest circumference place in piston shelf space 17 with the bottom of rear-bank rotor housing, an oil guide pipe 33 connects oilhole oil is imported in the tie-plate inner chamber 5 through round tube hole 32, be connected to an oil filter 39 on the oil guide pipe 33, another root oil guide pipe 18 communicates with through hole 15 and lubricates main shaft 4.So far, the lubrication system of rotary piston internal combustion engine each friction position of circulating lubrication in this way just.

When considering the engine shutdown state, the lubricant oil in the tie-plate inner chamber 5 can be built up in the bottom in piston shelf space 17 by gap everywhere, and then is full of the piston space 19 of inferior part of the cylinder block, so can change into by an oil pump feed.Concrete mode is: an oil storage tank places the position that is lower than cylinder body, oil guide pipe imports the machine oil of the bottom, largest circumference place in piston shelf space 17 in this oil storage tank, and an oil pump pumps into the machine oil in the oil storage tank in the tie-plate inner chamber 5 through oil filter 39 and oil guide pipe 33.

Because front-bank rotor housing 13 is the relative flat cylinder bodily form with the profile of rear-bank rotor housing 14, so help the cooling of cylinder body, only adopts air-cooled mode just can satisfy the cooling needs of motor even.On motor front-bank rotor housing 13 and rear-bank rotor housing 14 profile nose circle faces, many radiating fin are arranged, radiating fin becomes radiation-like on the cylindrical end face of front-bank rotor housing 13 and rear-bank rotor housing 14, and radiating fin is perpendicular to the cylindrical end face of cylinder body, and radiating fin is to have the high entity of certain length and width; Radiating fin can play the effect of heat radiation, can play the effect that increases front-bank rotor housing 13 and rear-bank rotor housing 14 mechanical strengths again; Two propeller fans place on the cylindrical end face of front-bank rotor housing 13 and rear-bank rotor housing 14.

In Figure 13, the air compressor of rotary-piston and vacuum pump: in order to obtain bigger working stroke, in order to obtain bigger compression ratio or aspiration vacuum level, piston space 19 on front-bank rotor housing 13 and the rear-bank rotor housing 14 can be one, its arc length also can be longer than piston shelf space 17 simultaneously, promptly increases the working stroke of plate shape piston 1 and the compression ratio of cylinder; Can also be the operations in a piston space 19 simultaneously of a plurality of plate shape pistons 1, promptly the quantity of plate shape piston 1 be more than the quantity of piston space 19, to improve sealing and isolated effect.When plate shape piston 1 moves on piston shelf 2 clockwise, the fluid flow port on the left side is for entering hole 20, the fluid flow port on the right is a tap hole 22, the entity of piston shelf 2 is filled and has been sealed the piston shelf space 17 that enters between hole 20 and the tap hole 22, a plurality of plate shape pistons 1 compress the fluid space in its place ahead with the effect of successive barriers, simultaneously aspirate the fluid space at its rear again with the effect of successive barriers, so just can guarantee has bigger output compression ratio, and bigger degree of vacuum.When plate shape piston 1 on piston shelf 2 counterclockwise during motion, entering hole 20 and fluid in the tap hole 22, to pass in and out direction opposite.It is higher that this structure mainly is used in fluid pressure, or in the equipment of small volume.

In Figure 14, the water pump of rotary-piston, water turbine and steam turbine: a plurality of plate shape pistons 1 rotate a circle only by the stenosis area 34 of a cylinder body and the spaciousness district 35 of cylinder body.Fluid inlet and outlet on the cylinder body all is located on the spacious zone 35 of cylinder body; Being shaped as of import and outlet is tubular, tubular import and tubular outlet on same axis, the intersection of locus of the axis of tubular import and tubular outlet and plate shape piston 1 planet operation, the axis normal of tubular import and tubular outlet is in the axis of main shaft 4.

No matter such structure is to water pump or water turbine, no matter to blower or gas-turbine, it is straight line with the direction that flows out cylinder body basically that fluid flows into cylinder body, and the flow direction of fluid is consistent with the sense of rotation of piston (impeller), thereby has improved effectiveness.General water pump flows into and the direction of outflow is inconsistent, because fluid also has quality, also will consume energy so change its flow direction.The direction that flows in the general water turbine and flow out is inconsistent, because fluid also has quality, will form flow resistance so change its flow direction, thereby weaken the kinetic energy of fluid.Because the edge of plate shape piston 1 and the gap in cylinder piston space 19 are very little, so the pressure of fluid all will be reflected on the plate shape piston 1, also since the top of cylinder body be stenosis area piston shelf space 17 and by piston and piston shelf obstruction, so the pressure of fluid can only act on the plate shape piston 1 of inferior part of the cylinder block, most of pressure of fluid can only act on the plate shape piston 1 of inferior part of the cylinder block in other words.Thereby realized the water turbine and the gas-turbine function of low pressure, low discharge and low flow velocity, also realized the water pump function of the slow-speed of revolution, big lift, big flow and self-priming.

In Figure 15 and Figure 16, the oil hydraulic pump of rotary-piston and oil hydraulic motor: on front-bank rotor housing 13 and the rear-bank rotor housing 14 a plurality of piston spaces 19 are arranged, the starting point of each piston space 19 with finish that end all has a fluid enter hole 20 and tap hole 22.For reaching the function of speed change, each fluid enter hole 20 or tap hole 22 all will be connected on separately on the combination brake switch and proporting.For preventing that oil hydraulic motor each plate shape piston 1 of when starting all is in the piston shelf space 17 and shuts down (hydraulic oil can not slurcocks shape piston), so the plate shape piston 1 greater than the number of piston space 19 is arranged on the piston shelf.

In order to improve the sealing effect of piston shelf 2 and cylinder body, on the piston shelf space of front-bank rotor housing 13 and rear-bank rotor housing 14, two seal grooves are respectively arranged, article one, seal groove is positioned at the outside of the radial position of piston space 19, another seal groove is positioned at the inside of the radial position of piston space 19, article two, seal groove all is a ring, seal groove and main shaft 4 concentrics, and the cross section of seal groove is a rectangle.On the two terminal circle plane of piston shelf 2, two seal grooves are respectively arranged, a seal groove is positioned at the outside of the radial position of piston hole 6, another seal groove is positioned at the inside of the radial position of piston hole 6, article two, seal groove all is a ring, seal groove and main shaft 4 concentrics, and the cross section of seal groove is a rectangle.Seal groove on the piston shelf 2 and front-bank rotor housing 13 are corresponding with seal groove on the rear-bank rotor housing 14.The seal ring of two large diameter seal rings and two minor diameters places the seal groove of cylinder body and piston shelf 2 respectively; The cross section of seal ring is a rectangle, in the seal groove of half of the axial entity of seal ring on cylinder body, and the seal groove of second half of the axial entity of seal ring on piston shelf 2.The effect of seal groove and seal ring is isolated, packed-piston frame 2 and fluid passage radially, piston shelf space 17.

The working principle of rotary-piston oil hydraulic pump is: when main shaft 4 drive piston shelfs 2 turned clockwise, the hydraulic oil on plate shape piston 1 its sense of rotation of promotion in the piston space 19 in the place ahead advanced and produces pressure, and hydraulic oil extrudes from tap hole 22; Plate shape piston 1 sense of rotation rear suction hydraulic oil, hydraulic oil sucks by entering in the hole 20.When main shaft 4 drive piston shelfs 2 were rotated counterclockwise, the turnover of hydraulic oil flowed to opposite.When 4 piston spaces 19 of oil hydraulic pump were all worked, the torsional interaction on the main shaft 4 was on the useful area of 4 plate shape pistons 1, so the flow of hydraulic oil increases, pressure reduces; When 3 piston space 19 bypass of oil hydraulic pump, during by 19 work of 1 piston space, the torsional interaction on the main shaft 4 is on the useful area of 1 plate shape piston 1, so the flow of hydraulic oil reduces, pressure increases.By flow and pressure once cover combination brake switch and proporting can regulate hydraulic press.

The working principle of rotary-piston oil hydraulic motor is: when hydraulic oil is pressed into the piston space 19 from entering hole 20, and 1 motion of hydraulic oil slurcocks shape piston, piston shelf 2 drives main shaft 4 and turns clockwise; When hydraulic oil when tap hole 22 oppositely is pressed into the piston space 19,1 motion of hydraulic oil slurcocks shape piston, piston shelf 2 drives main shafts 4 and is rotated counterclockwise.If the flow of hydraulic oil and pressure weighing apparatus are fixed constant, when hydraulic oil was pressed in 4 piston spaces 19 of oil hydraulic motor, the flow of hydraulic oil was by 4 shuntings, and the rotating speed of main shaft 4 reduces, and oil hydraulic motor has obtained the pressure of 4 plate shape piston 1 useful area, thereby the moment of torsion of main shaft 4 increases.With regard to the oil hydraulic motor of 4 piston spaces 19, the switching by a cover combination brake switch and proporting just can obtain 4 different rotating speeds, if oil hydraulic pump is also exported hydraulic oil with 4 flow velocitys, oil hydraulic motor just can obtain the rotating speed of 8 different big gear ratio so.
