Description
Technical field
The utility model relates to engine art.
Background technique
As everyone knows, reciprocating internal combustion engine has had the history in more than 100 year, is a kind of extremely successful hot merit switch machine.But because the human at present energy and the environmental problem that is run into had higher requirement to the hot merit switch machine.Thereby reciprocating internal combustion engine just seems that volume is big, weight is big, efficient is low, low emission is poor.Therefore in the last few years, people began to pay attention to especially the research and development of free piston engine, rotary piston formula motor and oscillating piston engine.Compare characteristics such as free piston engine has efficiently, low emission is good, and volume is little, in light weight with reciprocating-piston engine.Yet, because free-piston engine mostly is two-stroke, and can't directly use as the rotational power source, thus many power as generator, so its application is restricted.And conventional rotors piston engine and oscillating piston engine are because due to the correlation of its cylinder body and piston, its sealing, working life and low emission are had a strong impact on, and also there are swing type in oscillating piston engine and swing-rotor reciprocating engine or claim the transfer problem of pulsed power and rotating power.
In the recent period more about the research and the scheme of oscillating piston engine and pendulum piston type rotor engine, for example U.S. Pat 6,431, and 139; US4,068,985; US3,144,007; US3,356,079; US5,147,191; US 3,873, and 247; US4,174,930; US2,734,489; US6,886,527; US6,305,345; US5,433,179; US4,257,752; US6,009,847 and US2006/0191499 etc., world patent WO2008/104569; WO2008/012006; WO2007/096154; WO2007/073883; WO2006/089576; WO2003/093650; WO2003/074839; WO2002/084078; WO2000/060218; WO2000/042290; WO1998/026157 and WO1998/013558 etc., and Chinese patent ZL01134215.3 and ZL91201678.7 etc., multi-form oscillating piston engine and pendulum piston type rotor engine are all disclosed, the disclosed scheme of not superscript patent all existed a common shortcoming but all these and the applicant consulted, and there is the sliding interface of piston link in (wall thickness direction) in the cylinder wall in combustion chamber of air cylinder's seal section exactly.As everyone knows, no matter to motor or gas compressor, its sealing all is vital, and particularly concerning motor, its sealing has determined performance, efficient and the life-span of motor, is the most important problem in engine design and the manufacture process.And the sealing that is present in the sliding interface of (wall thickness direction) in the cylinder wall of combustion chamber of air cylinder's seal section is unusual difficulty, and particularly the reasons such as cold shrinkage and thermal expansion owing to motor make the sealing of this sliding interface more difficult.So the combustion chamber sealing by the motor of disclosed scheme production in the above-mentioned patent is difficult to be protected, thereby these schemes will be difficult to use in the commercialization motor is made.U.S. Pat 4,058,088 discloses the scheme of a kind of straight line type cylinder and slide block structure.In this scheme, because cylinder is rectilinear, so can only arrange by the string of a musical instrument of circle.So, meet at right angles between two cylinders or between two cylinder in-blocks, thus between two cylinders or the idle space between two cylinder in-blocks big, thereby caused the big weight of this scheme volume big.Moreover,, reduced the reliability of motor, particularly, can only bear, so influenced the seal and the efficient of motor by the outside inwall of cylinder because the huge centrifugal force that the piston swing produces can't be offset by the piston link owing to the existence of slide block.
In addition, present all oscillating piston engines, pendulum piston type rotor engine and free piston engine, the employing oil hydraulic motor, or adopt bent axle, noncircular gear or cam bawl formula ratchet that swing type power or title pulsed power-converting are become rotational power.Problems such as all there is poor reliability in these schemes, and efficient is low.
Need to invent a kind of new work engine, to improve the efficient and the low emission of motor for this reason.
Summary of the invention
The greatest drawback of conventional reciprocating formula motor is that piston does not have moment to bent axle, and less in suitable corner moment of resistance yet when blast stroke top dead center, thereby make high temperature and high pressure gas in the cylinder long heat loss that causes of holding time big, nitrogen oxide forms many, and efficient is low, and it is poor to discharge.And there be the shortcoming of sliding interface difficult sealing to overcome in (wall thickness direction) in freedom, rotor and the oscillating piston engine cylinder wall.The purpose of this utility model will disclose a kind of stop exactly and have moment, efficient height, the new work engine that discharging is good.

Also can make motor described in the utility model by four-stroke or two stroke operation by position and the timing relation of adjusting described arc cylinder rotary motor valve, described arc cylinder rotary motor also can use as gas compressor under the condition of dynamic input.Shown in Figure 22 is the distribution embodiment who uses as two stroke engine.
In arc cylinder rotary motor disclosed in the utility model, the swing between described piston space or described piston and described cylinder constitutes different oscillation systems.The system of described piston representative is meant described piston and follower thereof, for example, and described piston link, described half line shaft etc.The system of described cylinder representative is meant described cylinder and follower thereof, for example, and described cylinder connection piece, described half line shaft etc.The system of half piston representative is meant the piston and the follower thereof of half quantity, for example, and half piston link, described half line shaft etc.The system of half piston representative is meant in addition half quantity piston and follower thereof in addition, for example, and half piston link, described half line shaft etc. in addition.Swing between two oscillation systems is the basis of seal space volume-variation, also is the basis of engine operation disclosed in the utility model.For coordinating two relation such as Stroke Control and anti-collisioves etc. between the oscillation system, swing cooperating agency can be set between these two systems.Figure 23,24,25,26,27 and 28 is depicted as moment of momentum flowing type swing cooperating agency, between oscillation system A and the inertia structure A that freely rotates, moment of momentum hysteresis spring is set, between the oscillation system B and the inertia structure B with certain rotary inertia of freely rotating, moment of momentum hysteresis spring is set with certain rotary inertia.Described inertia structure can be a flywheel, but different with Chinese patent 200720035408.8, and in Chinese patent 200720035408.8, flywheel directly connects firmly with oscillation system, and flywheel is in free state in the utility model.For preventing the bump of described oscillation system and described inertia structure, damping block can be set shown in Figure 27 and 28.When swing takes place oscillation system, two oscillation systems will interlock and be subjected to moment of momentum hysteresis spring action, because have only the system of swing forwards just to be subjected to moment of momentum hysteresis spring action, Bai Dong system then is subjected to the direct effect of inertia structure backward.Adjust the inertia of inertia structure and the Hooke coefficient of moment of momentum hysteresis spring and mate different motors.
For realizing swing power or claiming of the conversion of pulse power to rotating power, all kinds of schemes so far all are to adopt the mechanical type anti-inversion organization, as ratchet, roller cam formula ratchet and roller friction type ratchet, or adopt noncircular gear or bent axle to finish this conversion.The former poor reliability, and the latter makes piston lose moment to line shaft when the blast stroke begins.Therefore the present mechanical type anti kickback attachment or the conversion of mechanical type rotating power are difficult to use in practice.In the described arc cylinder rotary motor disclosed in the utility model,, be provided with the hydraulic pressure anti kickback attachment for realizing swing power or claiming of the conversion of pulse power to rotating power.Described hydraulic pressure anti kickback attachment is exactly can only advance and can not fall back to a direction by two systems that fluid pressure can rotate relative swing again jointly.So just directly realized swing power or claimed of the conversion of pulse power to rotating power.This conversion is different fully with the oil hydraulic pump hydraulic motor system in the free piston engine that extensively adopts at present.Oil hydraulic pump hydraulic motor system in the free piston engine need with the oil hydraulic pump and the oil hydraulic motor of engine power coupling, be equivalent to be provided with in the power system dynamic power machine that three power equate, be motor, oil hydraulic pump and oil hydraulic motor, not only the cost high efficiency is also lower.The oil hydraulic pump that described hydraulic pressure anti kickback attachment in the utility model then only need be provided with control valve in very little liquid inlet gets final product, and cost is inefficient high.
In the utility model, described hydraulic type anti-inversion organization is made as the oil hydraulic pump formula that inlet is provided with control valve.Described control valve is made as self-controlled type (being free style) check valve, controlled formula check valve or other Controlled valves, as be subjected to valve-control spherical etc., as long as can the inlet of oil hydraulic pump be opened close by logical relation (being equivalent to the timing relation), promptly (when entering the mouth the feed liquor body) opens the oil hydraulic pump inlet when oil hydraulic pump rotates forward, when oil hydraulic pump will turn round the oil hydraulic pump inlet closed.Because inlet is provided with such valve, liquid can only advance and can not go out, so the line shaft of oil hydraulic pump can not reverse.Described half line shaft or its link of described motor are connected with the line shaft of described oil hydraulic pump, just can reach the purpose of anti-reversing.From oil hydraulic circuit, can be made as zero load loop or two kinds of load loops are arranged.Figure 29 is the structure of zero load anti-reversing oil hydraulic pump and an embodiment in loop thereof, at the place, liquid inlet of oil hydraulic pump control valve is set, and the liquid gateway of pump directly is communicated with.Rotatable two oscillation systems in the motor disclosed in the utility model are connected back (each system respectively connects a pump) respectively with the line shaft of described zero load anti-reversing oil hydraulic pump, oscillation system can't reverse, can only rotate forward, thereby finish of the conversion of swing power, make directly outputting rotary power of described arc cylinder rotary motor to rotating power.In order to make full use of the energy of oil hydraulic pump, described hydraulic type anti-inversion organization also can be made as the anti-reversing of load oil hydraulic pump formula.Figure 30 is the described embodiment that load anti-reversing hydraulic pump structure and loop thereof are arranged.Inlet is provided with the oil hydraulic pump of the liquid gateway of control valve through the load loop connection, and described load loop is made as the lubrication system of described arc cylinder rotary motor or is made as the cooling system of described arc cylinder rotary motor.So can omit oil pump or the water pump and the power thereof of motor.Described oil hydraulic pump can be made as gear type, plunger type, blade type, rotator type or other forms.
For the rotating power that makes described arc Cylinder engine is exported steadily reliable, oscillation system is set to a differential gear jointing type with differential mechanism in the utility model, another oscillation system is made as another differential gear jointing type with differential mechanism, the differential pinion gear housing is made as pto.Figure 31 is an embodiment of parallel Placement, and Figure 32 is an embodiment of coaxial Placement.
Disclosed arc cylinder rotary motor in the utility model, its intake duct, air outlet flue and oil circuit adopt the rotational slide joint to connect with gas handling system, vent systems and oil supply system respectively, and spark plug then adopts carbon brush or remote sensing form to connect.The valve of motor disclosed in the utility model can adopt into row's common type list valve, or adopts and advance to arrange separately placed type dual valve or many valves.Valve can be arranged on the cylinder sleeve or piston of described cylinder cap, described diaphragm type cylinder head, described cylinder.The control of valve can be made as cammingly, electromagnetic type or hydraulic type.
Disclosed motor can be used as diesel engine in the utility model, also can be used as petrol engine, and two-stroke and four-stroke all can.Piston can move rapidly at explosion time, the acting of can expanding in the shorter time of gas in the firing chamber is so overcome the shortcoming that piston thermal loss long in the top dead center waiting time, high-temperature gas efficient big, motor is low in the reciprocating internal combustion engine blast stroke, nitrogen oxide formation amount is many.Meanwhile also overcome the aforesaid drawbacks of oscillating piston engine, pendulum piston type rotor engine, free piston engine and rotary engine.
The utility model has following useful effect: described engine efficiency height, discharge, volume is little, low cost of manufacture, will open up a new road for the manufacturing of high-efficiency environment friendly h type engine h.
