Description

The rotary-piston rotator motor

Technical field:

The utility model relates to a kind of thermal power machine.What be particularly related to is a kind of rotary-piston type rotary engine.

Technical background:

Chinese patent CN2400574Y discloses a kind of " composite gear type internal-combustion engine ", is made of the complex wheel-tooth type gas compressor and the working machine of analog structure, and the high-pressure gas circuit passage of gas compressor is by the high-pressure gas circuit channel connection of one-way valve and working machine.The formation of its gas compressor comprises the closed shell of bringing gas port and high-pressure gas circuit passage into, be loaded on central gear and follower in the closed shell, be equipped with the little tooth of conjugation engagement on central gear and follower, also be provided with intermeshing canine tooth and big teeth groove on central gear and follower, canine tooth is separated into air-inlet cavity and compression chamber with closed shell; The formation of working machine comprise band high-pressure gas circuit passage and relief opening closed shell, be loaded on central gear and side wheel in the closed shell, on central gear and side wheel, be provided with intermeshing canine tooth and big teeth groove, canine tooth is separated into closed shell and fires chamber and exhaust cavity, also is provided with to lead to fluid fuel passage and the ignition mechanism that fires the chamber on closed shell.Its working principle is: the fresh charge that is entered by suction port is after the compression chamber compression of gas compressor, import the chamber that fires of working machine again through one-way valve, in firing the chamber, the fuel of being sent into by the fluid fuel passage fires under the effect of ignition mechanism, and the pressurized gas after firing promote the central gear rotation outputting power of working machine.The shortcoming one of the internal-combustion engine of this structural type is to fire the compressed gas in chamber respectively by failing " fresh charge " of the compression that comes from compression chamber and mixing formation by " fluid fuel " that the fluid fuel passage is sent into during firing the chamber, make its complex structure, make difficulty; The 2nd, the division surface sealing that the little tooth that is being rotated by the conjugation engagement between the compression chamber of compressor and the air-inlet cavity constitutes is not strong, makes the compression ratio of the gas in the compression chamber be difficult to reach requirement.In addition, the load mode by the one-way valve transmission is difficult to guarantee period of intake, easy break-down.

Summary of the invention:

The purpose of this utility model is that the internal-combustion engine to the said structure form improves, provide a kind of simple in structure, manufacture easily, rotary-piston rotator motor that Energy Efficiency Ratio is high.

The rotary-piston rotator motor of realizing the utility model purpose comprises and is provided with ignition mechanism, the cylinder body of combustion gas inlet hole and exhaust port, be located at rotor and retaining turbine and scavenge duct in the cylinder body, on the rotor periphery, be provided with at least one its outer end and stretch piston at cylinder body inner cylindrical wall face place, on the retaining turbine, have the groove that when rotating, passes through for piston, it is characterized in that described rotor the sidewall upper edge its axially have two grooves, described piston is fixed on the periphery of groove, described retaining turbine is installed in respectively in described two grooves by a retaining turbine axle parallel with rotor shaft, and retaining turbine surface and the surface of groove and airtight the touching of internal surface of cylinder body, described scavenge duct is equipped with pair of engaged gears by constituting with ventilation groove and the corresponding ventilation lumen that is communicated with two ventilation grooves that is located on the inboard wall of cylinder block that its groove communicates separately on the rotor body sidewall between two grooves that are arranged on rotor at a rotor shaft and an end that stretches out outside the cylinder body that keeps off the turbine axle.

The working principle of this rotary-piston rotator motor is as follows: two airtight chambers of inwall formation of the surface of the surface of epitrochanterian two grooves and two retaining turbines and two pistons and cylinder body, one of them is as compression air chamber, and another is as the burning air chamber.The combustion gas inlet hole then communicates with compression air chamber, and ignition mechanism and exhaust port then communicate with the burning air chamber.Rotor rotation during work, drive piston rotation, engaging gear on the rotor shaft drives the retaining turbine and rotates, the epitrochanterian piston that is in the compression air chamber meet with the groove that is docked at the retaining turbine in compression air chamber's groove and be able to by, after this piston turns over inlet hole, along with the rotation of piston towards compression air chamber's part of rotor steering direction, the volume of this part compression air chamber is reduced gradually, carry out compression process; Meanwhile, the volume of that part of compression air chamber of the another side of this piston then increases gradually, forms vacuum, and combustion gas is sucked in the compression air chamber, carries out breathing process; When meeting the requirements of compression ratio, epitrochanterian two ventilation grooves just in time go to the position of docking with the air-exchanging chamber of cylinder body, connect two ventilation grooves by air-exchanging chamber, and compressed gas then enters the burning air chamber through air-exchanging chamber, carries out gas exchange process; Rotation along with rotor, two ventilation grooves leave air-exchanging chamber, pathway closure between compression air chamber and the burning air chamber, gas exchange process finishes, ignition mechanism igniting this moment, produce high temperature and high pressure gas and promote the piston rotation in the fuel chamber and drive affixed with it rotor shaft to rotate, thereby realize the work by combustion process; The groove that is docked at the shelves turbine in the groove of burning air chamber in rotation process be in the piston of burning in the air chamber and meet and guarantee that it passes through.Along with the piston in the burning air chamber turns over relief opening, the burning air chamber and the relief opening that have before fired acting are connected, and waste gas is discharged from exhaust port, have realized exhaust process.Finish a work cycle.

Principle with existing multicylinder engine is the same, and being located at epitrochanterian piston can be uniform a plurality of piston.In such cases, divide the rotating ratio that is located at the engaging gear between rotor shaft and the retaining turbine axle then to be corresponding relation for number with piston.That is: when piston was two, the rotating ratio of engaging gear was 2: 1 then, made rotor rotation one circle, and the retaining turbine then rotates two circles, and two pistons all can be met with the groove of retaining turbine and pass through.The rest may be inferred by analogy.This is a sight of establishing a plurality of working rooms in a cylinder body, forms the single cylinder multiplex (MUX) and makes the cell structure form.Also can the high-power multicylinder engine of a plurality of such element of construction formation in parallel.Being arranged side by side a plurality of single cylinder multiplex (MUX)s on rotor sidewall makes chamber unit and can form many working rooms of multi-cylinder motor.

The utility model advantage compared with prior art is that air-breathing, compression work process are finished in compression air chamber, will burn and the exhaust work process in the firing chamber, finish.Simple and compact for structure, to manufacture easily, rate of fault is low, and compression ratio is realized easily, the functional reliability height.Alternative existing composite gear type internal-combustion engine uses.

Below in conjunction with drawings and Examples the utility model is described in further details.But content of the present utility model is not limited in the following example.
