Description

Rotary piston RC engine

Technical field: a kind of novel rotary piston RC engine---hypocycloid rotary piston RC engine.

Background technique: people are from the invention internal-combustion reciprocating-pisto, and a kind of rotary piston RC engine of dream invention has always been invented first rotary piston engine in the world in 1954 by German engineer's wankel finally.But, can't compete mutually with internal-combustion reciprocating-pisto because leakage of oil is serious.Leakage of oil point mainly concentrates on the seal arrangement on top, three-apexed rotor angle, not radially further not sealing of its apex seal with both sides, only the gas pressure by a side is not enough, the elastic force of the spring under the apex seal is too little, be sliding friction between the top of apex seal and the cylinder body during its reason, can't accomplish the zero clearance under the big pressure.Global inventor is just repeating his invention, constantly improves production technology, though the effort of process over half a century ends in failure at last.Trace it to its cause, mainly be to solve sealing problem, make and leak on three angles of corner pistons, the epicycloid of three angles and cylinder body is sliding friction, too small will the blocking in its gap changes motionless, its excesssive gap can leak gas, and rigid body Germany engineer wankel has been invented first rotary piston RC engine in the world, is called wankel engine again, till today, substantially there be not much being heated to become big, three angles of triangle piston make its gap become a large amount of gas leakage because of wearing and tearing or shrinkage, even accomplished the zero clearance, owing to be sliding friction, the also very fast quilt of apex seal rubs just little and leaks gas, so working life is very short.That is to say that the principle of wankel can not solve the sealing problem of rotary-piston, fails.Want success, must find new principle ability success.But he remains very marvelous inventor, and also the no one solves his problem up to now.

Summary of the invention: the objective of the invention is to find a kind of piston of can realizing to rotate, can realize the principle of piston seal again.

The object of the present invention is achieved like this: main shaft is that pto rotates around the center of axle.Forge triangularity at the middle part of axle, then rounding and mill out T type groove, screw and conical bore on three angles.The one-way valve sealing screw is installed in screw and the conical bore, place one-way valve in the conical bore of one-way valve sealing screw, sealing between one-way valve sealing screw and the distribution shaft seals with butterfly spring and sealing gasket, slide block and Stamping Steel Ribbon are installed in T type groove, mounting spring between slide block and the one-way valve, mounting spring is adjusted screw in the center hole of slide block, be used to adjust the sealing load of individual event valve, slide block right part fluting is installed butterfly spring in groove, bore a circular hole at the left part of slide block, the cylinder needle roller is installed in the circular hole, the left part opening of slide block exposes the cylinder needle roller, the pure rolling under the ring pendulum flank of tooth that makes cylinder needle roller and ring lay out is meshed, slide block can slide under the elastic force of butterfly spring, therefore, ring pendulum, slide block, no matter cylinder needle roller and main shaft are that heat rises, shrinkage, still wearing and tearing all keep the zero clearance sealing under the certain pressure.Butterfly spring will have enough big pressure could guarantee sealing, and because the engagement driving between cylinder needle roller and the ring pendulum is the pure rolling engagement driving, so no matter butterfly spring has how greatest pressure, can not be stuck yet, the Stamping Steel Ribbon sealing is installed between the left part of slide block and the main shaft.Slide block middle part fluting, groove has both sides naturally, its effect has two: first lubricant oil partly passes through individual event valve in non-compression knock, again by slide block slot lubricated and heat radiation with the cylinder needle roller, it two is that the gas sealing that the gap between cylinder needle roller and slide block is flow through is lived, in other words, cross first limit of groove when this part gas flow that flows through in the gap after, it is big that the space becomes suddenly, pressure diminishes, second limit of flowing through groove again with regard to difficulty how, the air of going in the groove is many more, pressure for the Stamping Steel Ribbon on slide block both sides is big more, seals tight more.

Inlet hole and exhaust port are conical surfaces at a root that is installed on the main shaft all, and head is a socket cap, and the center is on the screw of pore.The conical surface of screw and the conical bore on the main shaft are tightened the back sealing, and the head of screw is installed butterfly spring in proper order, heat insulation mitigation seal ring.Seal ring is with the distribution shaft sealing of the pore on the screw with the lid middle part.Distribution shaft is a part that covers, and promptly covers circulating lubricating oil, advances pure air and that part that scavenges, because this part function ratio is more, therefore specially with its called after distribution shaft.Distribution shaft is made up of three layers of sleeve pipe, and the outermost of distribution shaft is a key-course, and they are respectively by lubricant oil control flume and oil inlet hole, exhausting waste gas groove and exhaust port, pure air inlet groove and inlet hole are formed, and are the lubricant oil supply tube then from outside to inside successively, the fresh air supplying tube, exhaust emission tube.The middle part of the ring pendulum flank of tooth axial distribution of laying out at each ring is corresponding, partly is oil supply in that part of distribution shaft in non-detonation, and in the detonation part, the place near oil nozzle does not have oil supply exactly.Lubricant oil is by oil supply, and the one-way valve on the main shaft arrives slide block, and is lubricated to the sealing plate fuel feeding of two end face through the groove on the slide block again, to the cylinder needle roller, provides lubricated the cylinder needle roller and the ring pendulum flank of tooth and cooling through the concentrated flow at slide block middle part.Is the inlet hole that distributes apart from one another by 120 degree at each ring pendulum flank of tooth at an end of axial distribution, and its other end is the exhaust port that distributes apart from one another by 120 degree, and each inlet hole and exhaust port be 60 degree at interval.Air inlet and exhaust are by air inlet duct on the distribution shaft and air vent control, and zero lap.Promptly do not have air inlet and air inlet duct in compressing section and burning zone, inlet hole does not have exhaust and air vent, exhaust port yet.Oil outlet tube, suction tude and outlet pipe, link to each other with turbosupercharger in order to heat-shift at last in the same end input and the discharge of lid.

This patent is made up of two groups of ring pendulum, differ 45 degree between two groups of different ring pendulum, every group of ring pendulum has 1 to 6 ring pendulum, preferably is made up of four ring pendulum, one group of ring pendulum saying here is equivalent to a cylinder in the reciprocating internal combustion engine that we are familiar with, in same group the ring pendulum with encircle put between angle differ 90 and spend or 180 spend, seal by sealing plate, two ends are by the end seal plate sealing of end, and the one end is fixed by locking nut, and its other end is fixed after adjusting impacting force by nut by spring.The sealing plate outside is that seal ring carries out the sealing second time, also can.The ring pendulum is by four parallel bent axle transmissions, and crankshaft output end directly is connected with Injection Pump, and needn't connect with timing gear.Install by the bearing of lid and bottom is movable at the two ends of bent axle.The two ends of main shaft are also installed with bearing is movable by lid and bottom.

The middle part of ring pendulum is the ring pendulum flank of tooth, put the center of some tooth tops of tooth at ring, it is exactly the place, firing chamber, one circular hole is arranged thereon, circular hole has a groove to communicate with ring pendulum curved surface, the eddy current ring of making of heat-resistant material is installed in the circular hole, oil sprayer and spark plug are installed in the outside of eddy current ring, its inboard is the eddy current spray orifice, diesel oil produces the eddy current after-combustion through the eddy current ring after the oil sprayer ejection, spray to the firing chamber from the eddy current spray orifice through the groove on the ring pendulum curved surface again and burn once more, a burning arc is arranged on the slide block, make combustion gas form swirl combustion once more.Fluting and do not open the eddy current spray orifice on the eddy current ring when using gasoline or other fuel,, the eddy current ring has been a heat-blocking action.Also can be without the eddy current ring, gasoline or other fuel directly enter combustion chambers burn.Decide on actual conditions.Because the rotary-piston rotational speed is fast, be tens times of reciprocating piston, and good cooling water recirculation system arranged, can consider directly to burn with rock gas or biogas, or with gasoline mixed combustion.Wherein, using biogas directly to burn, is optimal selection, if success will be found a new outlet for municipal waste is recycling.

The cooling system of this patent has outer cooling of two kinds-water and internal water cooling but.Internal water cooling but is made up of two-part, promptly oil cooling but and water cooling, but except that the bearing of cooling bent axle and main shaft, primary lubricant is also cooled off cylinder needle roller, slide block, sealing plate and seal ring to oil cooling.Water cooling is divided into two-part, and a part of cooling water is with the ring pendulum flank of tooth, oil nozzle and spark plug cooling, and another part cooling water is that main shaft (1) is cooled off.

Lubrication oil supply system is made up of two-part: a part is entered by lid, and the lubricant oil that oil pump is transported is transported at the end, with the bearing lubrication of four bent axles and main shaft.In the groove of the bottom of the one-way valve inflow slide block of the bottom of process slide block, flow to cylinder needle roller and sealing plate then the oil groove of another part oil from distribution shaft, and the lubricated and cooling with them.

Ring pendulum curved surface has four identical teeth, cylinder needle roller on the main shaft has three. and the confined space that forms between each ring pendulum flank of tooth and two the adjacent cylinder needle rollers is forwarded to maximum space and forwarded to minimum space by maximum space by minimum space all is that main shaft turns over 45 degree, and 90 degree are one-period altogether.Forwarding minimum space at rightmost confined space to by maximum space is compressed-air actuated space, and main shaft turns over 45 degree.At this moment, the oil spout of fighting of spark plug of installing in the eddy current ring that gasoline of installing on the ring pendulum curved surface on the top circle of the ring at middle part on the right pendulum tooth or biogas are used and oil sprayer point, and oil sprayer oil spout and the compression ignite installed in the eddy current ring that the diesel oil of installing is used, this confined space expand into maximum by minimum then, and acting, main shaft turns over 45 degree again when finishing to doing work, and corotation is crossed 90 degree.Between two cylinder needle rollers 120 degree, greater than used angle 90 degree of said process, also remaining 30 degree.Just Sheng Xia this 30 degree are used to install the eddy current ring.On schematic diagram 3, rotary-piston, i.e. cylinder needle roller (10), the space between two cylinder needle rollers (10), we become working surface.On schematic diagram 3, when 0 spent, we claimed that temporarily he is first working surface at that working surface of that compressed minimum on the right side.His three working surfaces are worked simultaneously, we only to first working surface by wiping.When being about to expansion working after 0 oil spout when spending, this moment the firing chamber minimum.Forward 45 firing chambers when spending to and forward maximum to, expansion working is finished.Enter exhaust phase for the first time then.Forwarding 90 to sends it to finish when spending for the first time, air-breathing beginning for the first time, forward 135 air-breathing joint speed when spending to, spend to 180 degree by 135 again and carry out the compression exhaust second time, spend by 180 that to carry out second time to 225 degree air-breathing, spend to 270 degree by 225 and carry out compression exhaust for the third time, by 270 spend to 315 spend carry out air-breathing for the third time, spend to 0 degree by 315 and only to carry out air compression, not exhaust.Oil jetting combustion expands and does work near 0 degree, until till 45 degree.The following reciprocation cycle.This shows that the hypocycloid rotary piston RC engine also has the air inlet of reciprocating piston, compression, the burning work done, four strokes of exhaust are finished a work cycle.Finish each cylinder needle roller of this work cycle and need main shaft correspondingly to revolve to turn around 360 degree.Average each cylinder needle roller turns over 120 degree, just once main shaft turns over the expansion acting process of miter angle, once main shaft turns over the non-power process of 45 degree pressurized air, and this non-power miter angle just in time is that another group differs the process of the ring pendulum expansion working of miter angle with it.Three cylinder needle rollers of each ring pendulum, 135 degree that revolved round the sun, four ring pendulum corotation are crossed 540 degree, and the power angles that have 540 degree are the workmanship, greater than 360 degree, in other words, all dynamic transmission of each angle of main shaft.In theory,, add and have noninterchangeability man-hour though three ring pendulum corotation are crossed 360 degree, uneconomical.Two ring pendulum are also rotatable, but the power transmission angle has only 270 degree, transmission poor effect.A plurality of rings pendulum, such as 6 or 8 can, but cost is high slightly, the moving effect of totally 8 rings swing can be better and use two groups.

From schematic diagram, compression exhaust and the corner that expands between air-breathing are 15 degree each time, promptly once queue process every 30 degree, spend once breathing process every 30.When main shaft rotates, distribution shaft does not rotate, exhaust port on the main shaft and inlet hole and then rotate, and exhaust port on the distribution shaft and inlet hole do not rotate, therefore on exhaust port on the distribution shaft and inlet hole, mill out some grooves respectively, be used for connecting exhaust port and inlet hole on the main shaft, these grooves just make it treat air drain, and the shared angle of its length should be about 40 degree.Differ 45 degree on the distribution shaft between each air vent, differing 45 degree between each air-breathing groove.Consider exhaust and air-breathing between certain interval will be arranged, in order to guarantee sealing, also to deduct the suitable seal angle on both sides, Here it is selects reason about above-mentioned 40 degree.Exhaust treats that air drain is called for short air vent, and the air-breathing air drain for the treatment of is called for short air-breathing groove, and each ring pendulum occupies three air vents and three air-breathing grooves.The side at the corresponding distribution shaft of the ring pendulum flank of tooth that oil sprayer is installed does not promptly have air vent and air-breathing groove, does not have exhaust port and suction port yet.Successful to a die casting in order to cover with mould shaft, the spy presses the angle mean allocation with exhaust port on the distribution shaft and suction port.

Fuel system is respectively two groups of ring escapements and changes fuel supplying, every group of while fuel supplying, when the centre takes fire, when promptly changing expansion into, can carry previous small angle and shift to an earlier date fuel supplying by compression. when the knot quick burning burns, carry previous small angle and tie fast fuel supplying.Supply of fuel is without interruption, without timing gear.Bent axle revolution half cycle changes half cycle again and supplies another group ring pendulum flank of tooth expansion working just with one group of ring pendulum of supply of fuel flank of tooth expansion working.The selector valve fuel supplying that commutates is incessantly arranged between two groups.Selector valve is by the bent axle transmission, and bent axle revolution half cycle selector valve just changes once to, the one group of used fuel of ring pendulum wherein of supply simultaneously.

This patent has two suite axles and two groups of ring pendulum are formed, one group of ring pendulum of a suite shaft drive.Every suite axle is made up of several parallel bent axles, preferably is made up of four bent axles, and one every group ring pendulum is to several ring pendulum, preferably with four ring pendulum.Differ 45 degree between the two suite axles.

This patent also has a kind of with the type of oil cooling without water-cooled, and I claim that it is that water cools off outward.Promptly encircle the cooling water of laying out that do not have, main shaft does not have cooling water on (1) yet, and only the lubricant oil that this internal-combustion engine is flowed out flows into this internal combustion engine lubrication after cooling off through a profit heat exchanger heat-shift again.This will carry out saying after some tests again.

Concrete implementation column is as follows: in Fig. 1 and Fig. 2, following part is arranged: 1-main shaft, 2-lid, 3-exports opinion, at the bottom of the 4-, and the 5-spring, the 6-bent axle, 7-encircles pendulum, the 8-seal ring, the 9-sealing plate, 10-cylinder needle roller, 11-covers sealing plate, sealing plate at the bottom of the 12-, 13-end cover, 14-Stamping Steel Ribbon, 15-is sliding fast, 16-check valve spring, 17-one-way valve, the 18-heat insulation loop, 19-pore screw, 20-eddy current ring, the 21-oil sprayer, the 22-spark plug, 23-oil nozzle seal ring, 24-lid water oil seal ring, 25-lid water oil joint, 26-one-way valve sealing screw.The B1-locking nut, B2-spring and seal washer, B3-butterfly spring and seal washer, the B4-butterfly spring, B5-adjusts screw, B6-gasket ring.

In this implementation column, every group by two ring pendulum (7), by four parallel bent axles (6) transmission, the two ends of four parallel bent axles are respectively by the bearings on the lid (2) and the end (4), the mutual transmission of middle and two ring pendulum (7), the angle between two eccentric vectors on the every bent axle (6) are 180 degree.If every group is used four ring pendulum (7), this angle should be 90 degree.Here said eccentric vector is meant that the axle center at two ends of a bent axle (6) is for a bit, the center of circle of the eccentric circle of bent axle (6) is eccentric vector for the line of another point, the length of eccentric vector is exactly throw of eccentric, and throw of eccentric is e, and the angle between the eccentric vector of two suite axles differs 45 degree.The middle part of ring pendulum is the ring pendulum flank of tooth, it has four teeth, it is main shaft (1) that its addendum h equals in the e. ring pendulum flank of tooth, main shaft (1) processes three slide block slots, slide block (15) is installed in the groove, Stamping Steel Ribbon (14) and slide block butterfly spring (B4), most circular holes are arranged on the slide block, cylinder needle roller (10) is installed in it, there are a groove and circular hole in the middle part of slide block (15), screw (B5) and spring (16) are adjusted in installation in the circular hole, at the other end of spring (16) one-way sealing valve (17) are installed, by adjusting the adjustment of screw (B5) and spring (16) realization to the pressure of one-way sealing valve (17).Guarantee that butterfly spring (B4) is by pressure enough big pressurized air and the expanding gas that just can seal up firing chamber in of slide block (15) to cylinder needle roller (10), " blocking " phenomenon also can appear in big again pressure, this be because at first cylinder needle roller (10) to put between the flank of tooth with ring be the state of the pure rolling of zero clearance, there is not slip each other, next is to drive cylinder needle roller (10) at the elastic force bottom slide block (15) of butterfly spring (B4) can radially slide, and mechanical wear or expand with heat and contract with cold has muchly can " not blocked ".And reciprocating piston is certain to " being blocked " under the zero clearance.Even there is the gas of minute quantity to cross cylinder needle roller (10), under the enough big pressure of butterfly spring (B4), also kinetic energy can be stayed, the gas of running out of can be subsequently three times be changed in the air-breathing and exhaust.This patent has been Duoed twice ventilation than reciprocating piston, and the therefore last pressurized air that obtains is purer than the pressurized air of reciprocating piston, thereby efficient is higher.The gas pressure that the slide block both sides enter is big more, and the elastic force of butterfly spring (B4) is big more, and Stamping Steel Ribbon (14) sealing effect is good more.Sealing between cylinder needle roller (10) and the slide block (15) is to be finished by the elastic force of groove on the slide block between them and butterfly spring (B4).One-way valve (17) is installed in the individual event valve sealing screw (26), the conical bore of one-way valve sealing screw (26) the inside and one-way valve (17) sealing, the conical bore sealing on the conical bore of outside and the main shaft (1), end spring, seal ring and distribution shaft sealing.

All waste gas and fresh air all pass through from pore screw (19), sealing between pore screw (19) and the main shaft (1) is finished by the conical surface of the end of pore screw (19) and the conical bore on the main shaft (1), sealing between the other end of pore screw (19) and the distribution shaft that covers is by the seal ring B2 on the other end of pore screw (19), and heat insulation loop (18) and spring B 3 are finished.Spring B 3 give with the certain pressure of seal ring B2 to guarantee sealing, heat insulation loop (18) is used for protecting seal ring B2.

Between ring pendulum (7), seal with sealing plate (9) and seal ring (8), the upper end of ring pendulum (7) is topmost finished by lid sealing plate (11) and gasket ring B6, the sealing of the lower end of ring pendulum (7) bottom is by end sealing plate (12), and end cover (13) and filler thereof are finished.The top of main shaft is fixed by locking nut B1, spring (5) is passed through to adjust to end cover (13), end sealing plate (12), ring pendulum (7) by the locking nut B1 of below in the lower end, sealing plate (9), the adjustment of the pressure of lid sealing plate (11) and gasket ring B6 is to its axial restraint.Appropriateness is wanted in the pressure adjustment, pine can influence sealing effect, tight can the influence rotation.Seal ring (8) is a secondary seal, considers the cooling problem of sealing plate (9), also can be without seal ring (8).

Air inlet, exhaust and supplying lubricating oil are all by the distribution shaft control that covers.On the ring pendulum flank of tooth, with regard to axial distribution, encircle on the corresponding main shafts in two ends (1) of putting the flank of tooth and the pore air inlet of the end in the two ends on the distribution shaft, be called inlet hole, the pore exhaust of the other end is called exhaust port, and the middle part is taken out the lubricant oil that comes with oil pump and supplied to cylinder needle roller (10) by one-way sealing valve (17), sealing plate (9), lid sealing plate (11) and end sealing plate (12) are gone up lubricated.There is inlet hole to treat that air drain is communicated with between three inlet holes on three inlet holes on the main shaft (1) and the distribution shaft, inlet hole on the main shaft (1) rotates, and the inlet hole on the distribution shaft is fixed, therefore is communicated with this two-part inlet hole with regard to having invented with being called the device for the treatment of air drain.In like manner, the exhaust port on the main shaft (1) also treats that with exhaust port air drain is communicated with the exhaust port on the distribution shaft.These two kinds angles for the treatment of air drain respectively account for 45 degree or less than 45 degree, and two kinds of angles respectively account for 45 degree, differ 15 degree mutually, and non-overlapping copies, and this just makes exhaust and air-breathing non-overlapping copies, and carry out in the air drain treating separately, do not disturb mutually.Cylinder needle roller (10), suction port and exhaust port be separated by 30 the degree be evenly distributed on the main shaft (1).Outermost has three air inlet ducts on distribution shaft, and three air vents are corresponding with three ring pendulum flank of tooth, with a last ring pendulum flank of tooth, that ring pendulum flank of tooth that oil sprayer promptly is installed is corresponding, and that part on distribution shaft does not promptly have air vent, do not have air inlet duct yet, also do not have oil supply.This part is used for pressurized air after-combustion expansion working.The pressurized air main shaft must turn over miter angle, and burning expansion needs main shaft need turn over 45 degree, turns over an angle of 90 degrees altogether.Compression-expansion is carried out between two cylinder needle rollers (10), is 120 degree angles between two cylinder needle rollers (10), and 120 degree deduct 90 degree, also surplus 30 degree.The installation place of putting the oil sprayer (21) of the flank of tooth at ring is packing less.In order to seal, this 30 degree just in time is used for sealing up the installation place that ring is put the oil sprayer (21) of the flank of tooth, also has rich angle after the installation.The outermost surface of distribution shaft is a key-course, be used for air-breathing, the control of exhaust and lubricant oil and supply.Pure air layer is clipped in the exhausting waste gas layer and circulating lubricating oil is discharged between the layer, and this is in order to absorb their heat, fuel saving.Lid (2) is one-step die casting axially, and the distribution shaft on it is load capacity not, can design light.

Except that diesel engine need use eddy current ring (20), other type did not all use eddy current ring (20).

This patent is without timing gear, and the bent axle in this patent (6) just is equivalent to the camshaft in the internal-combustion reciprocating-pisto.(7) transmission of two groups of ring pendulum can only be arranged in this patent, be equivalent to two cylinder reciprocating piston IC engines.Fuel feeding in same group is identical constantly, and the time of ignition of the internal-combustion engine of same group of interior installation spark plug is identical, provides electrical signal by bent axle (7) for electronic-controlled fuel injection system.Do not need variable valve actuating mechanism.For diesel engine, directly drive in-line fuel injection pump or rotor distributor pump or special-purpose selector valve as live axle by bent axle (7).

Best eight bent axles (7) are all lifted one's head, and they can also distinguish the transmission lubrication oil pump, generator, circulating water pump, air compression pump, oil hydraulic pump and other devices.

Lubrication system: as shown in Figure 1, lubricant oil is divided into two-way: article one road is that the lubricant oil from the distribution shaft treats that oil groove enters into the slide block oilhole (see figure 5) on the main shaft (1), the one-way valve (17) that passes through again on the main shaft (1) enters slide block (15), on slide block (15), be divided into three branches, one flows to cylinder needle roller (10), with cylinder needle roller (10) cooling and lubricated, other two lubricated and coolings in two ends that flow to slide block (15).Can not enter of the oil outlet outflow of the lubricant oil of slide block (15) from distribution shaft.The second the tunnel is the bearing that (4) enter into main shaft (1) and bent axle (6) end of from, is gone up by lid (2) then and flows out.

Cooling water recirculation system: cooling water mainly cools off two-part, the ring pendulum flank of tooth of first ring pendulum (7), and it two is main shaft (1).Cooling water is to enter the tank laid out of the ring outside the expansion working face (hot side) from the ring pendulum flank of tooth, flow out from non-power air intake-exhaust face (huyashi-chuuka (cold chinese-style noodles)) again then, cold and hot surface boundary at tank is that a dividing plate separates cold, draw circulating water with elbow the both sides of dividing plate, uses flexible pipe to be connected with pipe joint on the lid (4) then.Upward drawn with seal oil and from intercommunicating pore by the end cap water oil joint (25) of lid (2) at main shaft (1), the water on the lid (2) after having seal ring (24) with the seal oil between main shaft (1) and the lid (2) is drawn recirculated cooling water.With recirculated cooling water the end of from (4) introduce main shaft (1).

Comparison with in the past internal-combustion engine: it has all advantages of reciprocating piston, has all advantages of wankel rotary-piston, and it is poorly sealed to have overcome the wankel rotary-piston, gas leakage, shortcoming such as the life-span is short.It is tighter than the reciprocating piston sealing, and efficient is higher.

As everyone knows, between a rolling disc and a fixed tray gas seal is lived, will accomplish 2 points, at first, the gap is zero between two dishes, and part surface is smooth, and is wear-resisting, and the suitable material of doing sealing is as the bus alloy.Secondly, to there be enough pressure just can reach sealing between two dishes.Generally adjusting to certain pressure with spring by nut just can reach sealing.This patent has utilized this principle to make the end face seal of cylinder needle roller (10) and the sealing that radial seal has reached the zero clearance with certain pressure exactly.No matter what have expanded with heat and contract with cold, no matter what have worn and torn, and made the gap error cause, all can be issued to the zero clearance sealing in the effect of spring (5) and spring B (4) and slide block (15), it seals has sternly surpassed reciprocating piston.And reciprocating piston is not accomplished the zero clearance.Even have a spot of combustion gas to cross cylinder needle roller (10), also kinetic energy can be stayed.

The air inlet that this patent also has each work cycle of reciprocating piston to comprise, compression, 4 piston processes of work done and exhaust.But this patent has the gas exchange process of three air-breathing and exhausts, and not exhaust when air-breathing, and not air-breathing during exhaust, pure air does not mix mutually with waste gas.Reciprocating piston is gas exchange process for once, and air-breathing some mixes with exhaust.Therefore, this patent is more much higher than reciprocating piston scavenging efficiency.

This patent is laid out simultaneously at same ring and is taken a breath and a direction compression-expansion in three directions, does not therefore have non-power idle running, even every group is had only a ring pendulum.And there is the non-power phenomenon of idle running in reciprocating piston.

There is not the dead point in this patent when the ring swing is moving, and the crank-connecting rod transmission of reciprocating piston has the dead point.Thereby the velocity ratio reciprocating piston transmission of this patent is stronger.

The rotary-piston of this patent is exactly cylinder needle roller (10), and it is that pure rolling is rotated.Therefore it is more steady than the reciprocating piston motion, and noise is littler, and especially effect is more obvious when high speed.。

Its ventilation mechanism is born by distribution shaft, is fixed.Both simpler than reciprocating piston, make easily again.

It does not have the planetary gears of wankel, so manufacture cost is lower, and rotating speed is higher.

The moving characteristics of ring swing are: each cylinder needle roller (10) and the engagement of its ring pendulum flank of tooth in the zero clearance. Because foozle is arranged, so that is gone round and round a millstone in that higher position, more mill is more smart, until grind to get the same height. Wearing part is replenished by spring.
