The machine has a housing and at least two rotors which counter-rotate on parallel axes so that lobes on one rotor engage with chambers in the other rotor, and that the free volume within the chamber decreases to a minimum and then increases. The peripheral edges of the chambers have seals which bear against the flanks of the lobes to provide a gas tight seal. Several lobed rotors can be arranged around one chambered rotor. Inlet and outlet ports can be at the same, or opposite ends of the rotors, which can be hollow to provide gas passages.

Description

The invention relates to a rotary piston machine in which there is at least one vane rotor rolls on at least one chamber rotor, and thereby work through a medium or / and Emits heat and / or takes up, such a working substance via at least one Rotor with the environment or other units of the machine exchanged becomes.

With the machine according to the invention, work can be generated or work can be carried out on it do. Depending on the embodiment, it can be used as a fuel internal combustion engine, with steam or other media can be used as a pressure-operated machine or as Pump, as displacer or compressor; the machine can also be combined suitable machine parts so that they run several of these applications simultaneously can perform. Analogous to an exhaust gas turbocharger, e.g. B. with the help of a Another medium can be sucked in and compressed. A medium can also be circulated between machine units, so that it can undergoes thermodynamic cycle of a hot gas engine.

1. The inventive machine as a heat engine

Thermal engines are differentiated into turbo machines and piston machines. The machine according to the invention can be assigned to the piston machines if one internal or external combustion of a medium work is to be generated.

In the reciprocating piston machines used in practice, a heated, mostly gaseous medium successively positive and negative pressure on a piston who exercises the pressure alternately in one and then in the opposite set direction and exerts a force on a flywheel via a crank mechanism, which turns round by periodically repeating this process.

So linear movements must be converted into round movements and such a col accelerate and decelerate periodically. To achieve this, it takes Control instruments that work very quickly with increasing demands on the machine become expensive and have a negative impact on efficiency, wear and tear consistency, the smoothness and ultimately the cost of such a reciprocating machine. Due to locally occurring very strong forces such. B. at the reversal points of the pistons the machine is also correspondingly massive and can only work to a limited extent choice of materials.

All of this has in the case of heat engines with internal combustion, such as the engines after Otto and Diesel repeatedly led to attempts to include the piston arrangement NEN ancillary units to be replaced by rotary pistons that like control units without the valve train get along.

So far, however, only the Wankel rotary piston engine with that on one Trochoid orbit over a rotating rotary piston guided by an extender drive gain practical importance.

The negative side effects of the reciprocating piston engine were largely affected avoided, but have the high Ver due to the unfavorable combustion chamber with high emission values and the required new sealing technology that after the initial engagement of engine and automobile manufacturers, the developments were largely discontinued.

A number of inventions have also been made about rotary piston machines at which cylindrical rotating bodies with cams and grooves roll against each other in a sealing manner should. However, putting it into practice obviously required considerable effort mechanical effort usually combined with additional new technology, so that to date none Machines of this type were built and distributed.  

The object of this invention was therefore, if it is to be used as an internal combustion engine, to combine the advantages of the reciprocating piston engine and the Wankel engine and thereby largely to avoid their disadvantages:

• - It must consist of a few components and control instruments such as valves, etc. can do without, which also causes a low friction of the mechanics,
• - All turned parts should only have real rotations, so that no crank drive is necessary and a low-vibration run with complete balancing of the masses is possible and a dead center and vibration-free and therefore low-noise and low-wear motor operation guaranteed becomes,
• - With the help of several operations per revolution of the drive shaft should be high Power density can be achieved
• - about the use of conventional and thus advanced technology in so many Areas as possible, e.g. B. in sealing, cooling and lubrication Storage of the machine parts, the supply of working material and their output as well as the Ignition, the development effort in the implementation of the new concept can be reduced grace,
• - It must be possible to provide an optimal space for the combustion in order to emit minimize values and consumption of working material,
• - There should be a wide variety of fuels on the market such as gasoline, diesel and gas can be used
• - In principle, there should also be hardly any common or new materials for this application can be used.

All aspects of this task can basically be done with the machine according to the invention to solve; depending on the embodiment, the aspects to different degrees can be worn.

The principle

The machine according to the invention is simple in construction, since it consists of only three different basic elements, namely at least one vane rotor ( 30 ), at least one chamber rotor ( 31 ) and the housing ( 32 ).

• - Vane and chamber rotors roll in opposite directions on the number of vanes and of the chambers dependent on each other.
• - A vane rotor ( 30 ) consists of an even number of vanes ( 34 , 36 ), which are separated from each other by segments of a vane rotor of the same size.
• - A chamber rotor ( 31 ) has so many chambers ( 52 ) that during the rolling from each other after a full revolution of a chamber rotor, all chambers were run through at least once by a wing.
• - The profile of a chamber rotor is designed so that the chambers through segments of the same size are separated from each other, which during the reversal sealing in certain phases on the segments of at least one wing Roll off the rotor.
• - During the rotation, the blades dip into the chambers in certain phases, creating spaces that are either limited by the chamber and blade rotor ( 71 , 72 ) or by the blade rotor and housing ( 73 ) or by Chamber, vane rotor and housing ( 74 ), which vary in volume and position as they continue to rotate.
• - In the different rooms there is either suction, compression, expansion or ejection of the liquid and / or gaseous medium instead, the medium in certain time intervals and at defined positions of chamber and wing Rotor undergoes a physical-chemical change to each other (i.e. is ignited and burns).
• - Both the fresh medium is sucked in and the exhaust gas is discharged via the wing Rotors.
• - A wing rotor ( 30 ) has at least one suction ( 76 ), at least one discharge ( 77 ), at least one compression ( 78 ) and at least one expansion side ( 79 ) each on the wings.
  There is an ejection side on the front and a suction side on the back of one wing ( 36 ) as well as a compression side on the front and an expansion side on the back of at least one of the other wings ( 34 ).
• - In each case one expansion and one discharge side as well as one compression and one suction side face each other correspondingly, i.e. they enclose a room if one of the two wings is not sufficiently far in a chamber, the compression and the discharge sides of the direction of rotation ( 80 ) facing a vane rotor and the suction and expansion sides facing away from the direction of rotation of a vane rotor.
• - Here, both the intake and the exhaust side are connected by separate ge channels ( 38 , 44 ) in a wing rotor with the corresponding outdoor units (exhaust on the exhaust side, carburetor, air filter on the intake side) ( 35 ).
• - The channels can be designed in their shape and dimensions such that the suction of the fresh medium and the emission of the exhaust gas optimally to the requirements nisse of the engine are adjusted.
• - The chambers ( 52 ) of a chamber rotor can each have a bulge ( 82 ) on the side facing the direction of rotation ( 81 ) of a chamber rotor as a combustion chamber wall.
• - The shape and dimensions of such a bulge can be designed so that the ignition and combustion process of the medium can run optimally.
• - Likewise, a bulge ( 89 ) can also be worked into the compression side of the wing if this serves to optimize the design of the combustion chamber. The expert knows how to optimally design a combustion chamber.
• - Each bulge ( 82 ) of a chamber ( 52 ) is sealed at least once per full revolution of a chamber rotor through the compression side of a wing to the rest of the chamber. If an ignition device ( 84 ) is required to ignite the medium, this is attached and controlled in such a way that the medium is ignited, depending on the optimization of the combustion process, in the time band immediately before to immediately after the bulge is completely sealed. The ignition device can be controlled via a slip ring ( 88 ) similar to that of a conventional distributor.
• - The expansion side can be designed so that the burning working medium provides an optimal working pressure with minimal temperature loss. Because the working medium initially spreads only into the space ( 71 ) delimited by the expansion side and chamber, there is only a slight temperature loss per unit of time in the first phase of the combustion; this favors the desired largely complete combustion, which contributes to increasing the efficiency and reducing the pollutant emission.
• - The expansion side can be designed ( 83 ) so that to avoid a negative pressure while passing through the chamber through the chamber in this space formed by the expansion side and chamber wall ( 71 ) penetration of the medium (the exhaust gas), which can occur in the space ( 74 ), which is formed by a wing rotor with a corresponding ejection side, chamber rotor and housing ( 32 ). Such a recess, also in the form of a connecting channel, can also be located in the rotor chamber.

How it works

This arrangement does the following:

• - ( 14 ): The rotation of the vane rotor ( 30 ) enlarges a space ( 74 ) delimited by the suction side ( 76 ) of the vane rotor and by the chamber rotor ( 31 ) and housing ( 32 ), as a result of which an ignitable mixture , ignitable gas or air is sucked through the intake duct ( 38 ) into this room.
• - ( 15 ): This working material is transported until it is only limited by the suction and compression side ( 78 ) of the vane rotor and by the housing ( 73 ).
• - ( 16 ): The space ( 73 ) thus created is sealed off from the environment after the suction side has been immersed in the chamber ( 52 ); as it rotates further, it shrinks and in this way compresses the working fluid, which, if an injection is to be provided, can be carried out directly into the chamber via a conventional injection device ( 85 ).
• - ( 17 ): The working medium is further compressed ( 72 ) as the rotation progresses by immersing the compression side ( 78 ) in this chamber until it is completely enclosed in the bulge ( 82 ) of the chamber by the compression side and the ignition point is at an angle shortly before until shortly after reaching this state. The ignition device ( 84 ) can be hen closer to the opening to the chamber in order to bring the medium that escapes first to the combustion, whereby the person skilled in the art can determine the optimal positioning of the ignition device and the ideal ignition time.
• - ( 18 ): The chemical-physical change in the working fluid initiated by the ignition leads to an increase in the pressure which is passed on to the chamber walls and to the expansion side ( 79 ). The work done with it causes a further turning hen both the chamber ( 31 ) and the wing rotor ( 30 ); in this way the space ( 71 ), which is delimited by the expansion side ( 79 ) and the chamber, is initially enlarged. As a result, the space is initially only slightly increased per unit of time, so that the medium cools only slightly, which is desirable for a good combustion process.
• - By further rotation, the wing comes out of the chamber and the space ( 74 ) which expands further under pressure is further enlarged until the space is limited by the ejection and expansion side and the housing ( 73 ) and no others Expansion takes place.
• - ( 19 ): As the rotation progresses, the wing with expansion ( 79 ) and discharge side ( 77 ) dips into a chamber ( 52 ), so that the space ( 74 ), which is now through the discharge side, the housing and the chamber -Rotor is limited, begins to decrease, whereby the discharge of the working material is initiated via the discharge channel ( 44 ).
• - ( 20 ): As soon as the exhaust side has passed through the chamber, all the exhaust gas is displaced except for the remainder in the bulge ( 82 ) and the suction of fresh working material through the expansion side has already begun, so the cycle starts again.

Execution

In principle, very different embodiments are conceivable, with which the above principle described can be realized. The simplest arrangement with one wing and one Chamber rotor does not guarantee a complete exchange of the working material. On the other hand are series connections of more than two chamber rotors with a corresponding number Vane rotors mostly from a room ergonomic point of view but also due to the mecha only makes sense in individual cases. The same applies to the internal combustion engine also with regard to the wing rotors with more than two wings, i.e. four or six, which then correspond with chamber rotors with a corresponding number of chambers.

An advantageous simple embodiment of the rotary piston machine according to the invention is an arrangement of a chamber rotor ( 31 ) with four chambers ( 52 ) and two vane rotors ( 30 ), each with two vanes ( 34 , 36 ), in the middle of the chamber rotor lies between the two wing rotors.

To increase performance, such units can be opened without too much mechanical opening wall connected in series so that the chamber rotors and two vane rotors each have common axes.

The axes of rotation of vane and chamber rotors can run in parallel, but they can also include an angle ( 75 ) if such an arrangement of z. B. Saving space proves to be more advantageous.

In this embodiment, the ratio of rotation from chamber to vane rotor is 1: 2. After each quarter turn of the chamber rotor, whose axis of rotation can be designed as a drive shaft ( 86 ), the working cycle is initiated alternately by both vane rotors, so that such a drive shaft acts four times per full revolution.

The design of the vane and chamber rotors can be made very differently be, the shape of the peripheral surfaces of chamber and vane rotors, part as the housing largely depend on each other, since each seg elements must seal each other when the rotors roll against each other.

In the simplest and therefore also the least expensive version, the basic bodies of the rotors are cylindrical ( 105 , 106 ); Similar to the rotary piston according to Wankel, edges and corners have to be sealed, so that modified sealing strips can be used here, as used in currently produced Wankel engines.

Preferably, the sealing elements ( 60 ) according to the invention are used, which can be expected to have a particularly good sealing behavior, since these sealing elements are elastically gela and thus temperature fluctuations and different movements of the surfaces to be sealed can compensate very effectively.

Using today's advanced manufacturing technology with CAD / CAM support are further conceivable embodiments of the rotors conceivable.

The peripheral surfaces of the wings / chambers can also have oval, elliptical, round or other shapes ( 70 ) without corners. In these cases, the sealing can be carried out in a conventional manner analogously to the reciprocating piston with modified piston rings.

Accordingly, not only the wings ( 34 , 36 ) but also the chambers ( 52 ) can be provided with one or more sealing rings, the sealing effect on the wings by pressing together and which can be achieved in the chambers by pulling the piston rings apart.

The chamber rotor is rotatable and sealed to the parts in contact with the housing ( 32 ). Even if the really high pressures are only created in the chambers, the sealing can also be carried out accordingly using the sealing elements described above: it is also possible to achieve a sealing sliding movement of the rotor with a minimal distance to the housing parts.

Depending on the phase, each segment of a chamber rotor faces a vane rotor in the free space and the housing part; this means that a sealing device does not work permanently. This must be taken into account to the extent that the Dichtele element, if it is provided for example at the chamber end ( 57 ), does not block the free rotation during immersion in the housing section ( 58 ). This can be done by a corresponding z. B. wedge-shaped design of the sealing element ( 61 ), which faces the tapered side of the direction of rotation ( 81 ) of the chamber rotor, be it that this seal should be provided in the rotor or in the corresponding housing part.

In a further embodiment, the chamber rotor is mounted in the housing section in such a way that its distance from the housing section ( 58 ) into which the chamber end ( 57 ) first dips after the wing has rolled out of the associated chamber ( 52 ) , is greatest, the distance between this chamber end ( 57 ) and the housing decreasing as it is turned further, so that the sealing effect can initially increase continuously. In this way, modified conventional piston rings can be provided again if the peripheral surfaces are designed accordingly.

In order to achieve an effective sealing of the chambers, it makes sense that they are enclosed on all sides by the rotor housing. This has the consequence that the maximum height of the chamber ( 52 ) and thus also the wing ( 34 , 36 ) is less than that of the chamber rotor, so that a wing rotor ( 31 ) above and below the wing circular segments may have, which roll on cylindrical segments of the chamber rotor sealingly tend.

Even if the sealing of two cylindrical bodies usually no additional you If necessary, a chamber rotor can be turned against housing parts using the state of the art Sealing technology.

On one side of the rotors, the drive transmission ( 33 ) can be provided in a simple design as intermeshing gearwheels, while the ignition device ( 84 ) is provided on the opposite side.

From there, ignition elements ( 87 ) protrude into the chamber, which are comparable to conventional spark plugs at their ignition end and can also be fastened by threads in the rotor and protrude from the surface of the rotor with a contact. On the housing side corresponding to this rotor side, z. B. a current-conducting slip ring ( 88 ) may be provided which at certain times leads current via the contacts ( 87 ) of the ignition elements and thus initiates the ignition.

The simple replacement of these ignition elements can be done by means of this and with the Screw holes screwed into the housing.

It is provided that the working material consist only of air and thus the fuel is to be injected, depending on the type of combustion desired, an injector ( 85 ) must be executed in the housing. A variant comparable to direct injection is achieved if the injection into the chamber takes place immediately before the wing is immersed therein.

It is known that chambers ( 82 ) which are as spherical as possible represent ideal combustion chambers; however, the subsequent pressure expansion as the combustion progresses can show that deviations from this overall lead to a more favorable embodiment. In principle, any number of possible variants can be made in the embodiment with a large range of modifications in the selected volume, so that different compression ratios can be realized in the same other dimensions of the machine.

It is also possible that the compression side ( 78 ) of the vane rotor, that is, the direction of rotation ( 80 ) of the vane ( 34 ), which has no channels, the side facing the design of the combustion chamber ( 83 ). On the back of this wing ( 34 ) is the expansion side ( 79 ). It affects the pressure of the burned mixture after ignition and its embodiment and the inclusion of a suitably designed chamber wall ensure that exhaust gas can flow in when the expansion side is immersed in a chamber, so that there is no negative pressure in this chamber section ( 71 ).

For this wing ( 34 ), the wing ( 36 ) corresponds to the suction ( 76 ) and the exhaust side ( 77 ).

The suction side ( 76 ) is on the side facing away from the direction of rotation ( 80 ) of the vane rotor. On this side a channel ( 38 ) opens, which leads through the rotor to the center and on one of both sides (42) its second opening ( 39 ), through which the channel is connected to the air filter or the carburetor ( 35 ).

The ejection side ( 77 ) lies on the side facing the direction of rotation ( 80 ). Exactly according to the intake side there also opens a channel ( 44 ) which leads to the center of the rotor and there on the opposite side ( 43 ) has its second opening ( 39 ) through which this channel is connected to the exhaust.

It is also possible that both channels have their second opening on the same side ( 107 ).

Like the chamber rotor, the vane rotors are centrally supported by conventional bearings and sealed against the housing in accordance with the state of the art. The axis of rotation of the chamber rotor designed as a drive shaft ( 86 ) protrudes on one or on both sides from the housing ( 32 ), whereas the two-part hollow shafts formed from vane rotors with their respective openings in the housing recesses are rotatably supported. The supply lines of the corresponding units ( 35 ), however, are firmly connected to the housing in a sealing manner.

The channels and their openings can have one shape and dimension Vary the wide range and thus their function of suction or discharge be optimized accordingly.

The machine can be tempered using water cooling. Critical overheating Zones such as B. inline engines are omitted here. The exhaust fumes by design a relatively long time in the case and are initially after their initial expansion transported at a constant volume in the housing before they are pushed out. In many cases, due to the relatively large housing surface area, the apparatus-technically simpler air cooling may be sufficient.

The lubrication can be carried out according to the prior art, for. B. either by adding oil for fuel or by means of oil pressure lubrication.  

2. Pressure operated machines / pumps, compressors

In another application, a rotary piston machine is used over a work material that was previously pressurized in a reservoir. This pressure exerts the medium on a plunger and while it is expanding work is being done; then The working material is pressed out of the machine and the cycle begins from the beginning. According to this method, z. B. a steam engine.

With the help of slight modifications of the embodiment described for an internal combustion engine form of the machine according to the invention, in which the exchange of a medium is not only about the wing rotors but also via the chamber rotors, this can be called pressure operated machine or operate as a pump and compressor, again the Disadvantages of a reciprocating piston engine can be avoided.

2.1 Pressure operated machines

The principle is first demonstrated on the pressure-operated rotary piston machine at the at least one medium is pushed out of the machine via the wing rotors.

A first modification concerns the wing piston. According to the other mode of action the functions of suction and compression are not required.

Each vane rotor ( 30 ) can now also have an odd number of vanes ( 45 ) if many chambers ( 52 ) are provided in a chamber rotor ( 31 ) according to the rotation ratio. In any case, each wing ( 45 ) has an ejection side ( 77 ) on the side facing the direction of rotation ( 80 ) of a wing rotor ( 30 ) and an expansion side ( 79 ) on the side facing away from the direction of rotation. This means that from each wing ( 45 ) a channel ( 44 ) leads from the respective discharge side of the wing to the center ( 39 ) and there either on the same ( 42 ) or on different housing sides ( 42 , 43 ) in connection with the environment stands.

In contrast to the design of the machine according to the invention as an internal combustion engine, each chamber rotor ( 31 ) is now involved in the exchange of the medium with the environment. This is achieved in that a chamber rotor has a recess ( 46 ) in the center about its axis of rotation over a certain proportion of its depth, on which it is rotatably mounted on a machine part ( 47 ). This machine part is usually stationary itself, so it can e.g. B. also be part of the housing. In this machine part ( 47 ) channels are provided, which on the one hand open on at least one side of the housing ( 49 ) and in this way establish the connection with the outside world. On the other hand, they open along the wall of the recess ( 46 ) of the chamber rotor. In a simple embodiment, this recess is provided in a circle in the center around the axis of rotation of the chamber rotor over its entire depth, and the stationary housing part ( 47 ) including its channels ( 48 ) is in the form of a cylindrical sleeve with openings ( 54 ) in its walls performed, which lead on one ( 49 ) or on both sides ( 49 , 50 ) out of the housing and can be divided into two if z. B. more than one working substance is to be used.

The chambers also have channels ( 51 ), which on the one hand have their opening ( 53 ) on the side of the chamber wall facing the direction of rotation ( 81 ) of the chamber rotor. On the other hand, they open into the walls of the recess ( 46 ) so that certain openings ( 53 ) overlap in certain phases of rotation for a certain time with the openings ( 54 ) of the channels ( 48 ) of the fixed housing part ( 47 ) , and thus establish a connection between the surroundings and the chambers.

If it proves necessary, these overlaps can be sealed off from one another using simple means according to the prior art. If a control of the working fluid flow made possible by a machine part ( 47 ) is not necessary or is to be accomplished in another way, a chamber rotor can also only be rotatably mounted in the housing openings analogously to the vane rotors, the feed lines from the reservoir being fixed are connected to the housing ( 32 ).

Since the function of a combustion chamber in the chamber is unnecessary, a bulge ( 82 ) can be omitted if it is not used to optimize the pressure transmission to the expansion side of the wing.

In the representation of the mode of operation, the pressure-operated rotary piston machine is designed such that the medium passes under pressure via the chamber rotors ( 31 ) into the machine and passes this pressure on to the vane rotors.

However, the machine according to the invention can also be under pressure via one or more de Working materials are driven such that the medium in the wing rotors in the Machine arrives and exerts pressure on the chamber walls and finally the Ma again leaves the chamber rotors.

A working fluid can be pressurized in a reservoir which is connected to the housing part ( 47 ). During the rotation of the chamber rotor, a position is reached in which this reservoir begins to communicate with the chambers ( 52 ). Chamber and vane rotors are matched to one another such that a vane ( 45 ) with its expansion side ( 79 ) at the same time the opening ( 53 ) of this chamber ( 52 ), which is in the direction of rotation ( 81 ) of the chamber rotor facing away from the chamber wall, closes ( 21 ).

In principle, it is possible for the rotors to rotate in the same direction as described for the design as an internal combustion engine, but the opposite direction is also possible. Which ultimately leads to the greatest work yield also depends on the design of the channels with their opening and the shape of the chambers ( 91 , 92 , 93 , 94 ) and the wings.

As soon as the pressure of the medium acts on a wing and the corresponding chamber wall, it expands into a space ( 22 ) which is initially formed by the chamber and wing ( 71 ) and later also limited by housing parts ( 74 ). Depending on the size of the possibility of overlapping of the openings ( 53 ) and ( 54 ), further working material penetrates into the chamber and contributes to the development of work. By control devices according to the prior art such. B. normal rotary valve, which vary the width of the openings ( 54 ) in the fixed housing part is one of several ways to control the flow of the medium.

By turning the rotors further, the working material is first expanded ( 23 ), then transported without changing the volume ( 24 ). Finally, it starts to push it out of the machine ( 25 ) as soon as the ejection side ( 77 ) of the wing following the work comes out of the chamber ( 52 ) until all the medium except for the remainder remaining in the corresponding channel ( 51 ) of the chamber is pushed out ( 26 ) and the cycle begins again.

If the machine according to the invention is constructed analogously to that described in detail for internal combustion engines, a chamber rotor also receives four pulses per full rotation here. Are a chamber rotor z. B. assigned four vane rotors with two vanes ( 112 ), the drive shaft receives 16 (2 to the 4) pulses.

It can also prove to be advantageous that the pressurized medium is passed through the vane rotors and released via the chamber rotors. In this case, the vanes on the side facing away from the direction of rotation ( 80 ) of the vane ( 45 ) have a conductive side ( 79 ) into which the channel ( 38 ) opens, through the vane rotor to the center ( 39 ) and from there on one side ( 42 ) leads out of the housing ( 32 ) in order to then be connected to the reservoir.

In this variant, the medium flows continuously from the vane rotor into the Machine and is ejected in certain phases.

The discharge takes place via the channels ( 51 ) of the chambers ( 52 ) which open on the side of the chamber wall facing the direction of rotation ( 81 ) of a chamber rotor and then via at least one channel ( 48 ) of the housing part ( 47 ) in the phases of Rotation in which the corresponding openings ( 53 ) and ( 54 ) overlap.

Basically, it is also possible, for. B. let two different agents act on a machine in the described embodiment. In this case, the channels ( 48 ) of the fixed housing part ( 47 ) are separately connected to two different reservoirs. In the described embodiment, each chamber ( 52 ) of the chamber rotor comes into contact with both working materials after a certain number of revolutions of the vane rotor, so there is thorough mixing of the working materials.

If the machine is designed such that the housing part is not fixed, but rotates at the same speed as the vane rotor ( 30 ), the same openings always overlap, so that mixing can be avoided in this way.

2.2 Pump / compressor

Of course, the machine according to the invention can also be used in opposite directions be operated as a pump or / and compressor, at least one Working fluid is sucked in from a reservoir and compressed by the machine.

The rotors of the machine are made to rotate ( 108 ) by an external force, a medium being sucked in by increasing the volume of the corresponding space via the suction side ( 76 ) of a wing ( 45 ) facing away from the direction of rotation ( 80 ) of the wing rotor. During the further rotation, the medium is then first transported in the space ( 73 ) delimited by the housing and vane rotor, before it is increasingly compressed ( 109 ) through the compression side ( 78 ) of the vane into the chamber ( 52 ) and then is pushed out of the chamber rotor via the associated channel ( 51 ), which opens on the side of the chamber wall facing the direction of rotation ( 81 ) of the chamber rotor, as soon as the openings ( 53 ) and ( 54 ) overlap ( 110 ).

A simple turbine can also be provided in the fixed housing part Support the onward transport to the destination or at which energy is also removed men can be.

It is also in the design of the rotary piston machine according to the invention as a compressor possible that the medium does not get into the machine via the wing rotors and the chamber rotors out again but also vice versa. The resulting and different control of the flow compared to the first described embodiment of the medium, can lead to different pressure profiles, suction or compression performance and lead to efficiencies that can ultimately determine the choice of design.

3. Exhaust gas turbocharger

Just as, for example, suitable for increasing performance but ultimately arbitrary many chamber and vane rotors with different numbers of vanes and on them tuned chambers can be combined into units, it is also possible in this way with the rotary piston machine according to the invention two different tasks simultaneously to execute.

If the machine according to the invention with both a pressure-operated and with a ver sealing functional unit executed, it can, for example, the task of an exhaust gas perceive turbochargers, which in practice not primarily with pistons but with the help are powered by turbines.

With the help of the machine according to the invention, the object can be achieved in that it consists of at least one pressure-operated machine part and one machine part working as a compressor. For this purpose, the corresponding machine parts are simply connected to one another via suitable drive transmissions ( 103 ) provided with the desired transmission ratio. It is possible to accommodate these machine parts in a housing ( 104 ) and in this case also to dispense with an additional drive transmission ( 103 ) if both machine parts rotate in the same direction, or if this results from e.g. B. is desirable for reasons of spatial engineering, also in different housings, the connecting elements of which represent the drive transmissions.

If the sleeve is rotatably mounted, such a machine can be divided into two wings and one Chamber rotor can be realized.  

4. Hot gas engine

Another type of drive, which previously only used engines with reciprocating pistons and crank mechanisms came and who also realized with the advantages of the inventive machine the hot gas engine based on the Stirling principle provides this.

This is a heat engine with external combustion, in which, for. B. heat is generated by chemical / physical conversion of an external working substance, which is transferred in a certain phase to a gas which moves a displacer and a working piston in a closed system in such a way that the thermodynamic changes in the state of this medium regarding temperature, Pressure and volume in a PV diagram ( 27 ) from two isochors ( 28 ) and two isotherms ( 29 ) can be represented in a closed cycle ( 113 ).

In P1, the medium is in a low temperature state, with the lowest Pressure fills the largest space. In the direction of P2, this medium is at a constant temperature rature compressed under pressure increase; in P2 it is heated so that there is a significant pressure experiences an increase in the direction of P3, since it can no longer expand.

In the direction of P4, the working substance was given the opportunity to rise at a higher temperature to expand under pressure associated with work until it is the Ver available maximum space. Then it cools down Pressure reduction at a constant volume back to the initial state.

In the isochoric processes, the space available to the medium may be also due to the constantly moving displacement and working pistons in this phase In principle, do not change the volume.

On the other hand, there are phases in which the medium with a slight increase in pressure is compressed and on the other hand it expands to perform work. As a result, now a volume change takes place due to the moving displacement and working pistons that must.

Both can only be achieved with the reciprocating piston arrangement if the control of the Movements of the displacement and working pistons over interconnected, different crank drives. This combined with the tempera to be overcome differences, an acceptable engine running and effective efficiency again quite a sophisticated mechanism.

Nevertheless, the suitability for many substances has been associated with low noise and low pollution led to recent developments in the field of hot gas moto However, so far only in versions with reciprocating pistons and crank mechanisms exist; especially now also through further developments in heat generation such. B. new burner technologies here is a very interesting alternative to the low-pollution internal combustion engine Combustion is given.

For this application there are again various options, such as the task through the Rotational piston machine according to the invention by suitable combination of machines units can be solved.

The mode of operation will be described in the following with an advantageous embodiment ( 100 ) of the machine according to the invention, in which a medium in a closed circuit runs through various phases of the cycle at predetermined times by the machine.

It consists of two machine units, which are identical in construction, but rotate in opposite directions, and each have a chamber ( 31 ) and two vane rotors ( 30 ), each with two vanes ( 45 ). One machine part ( 98 ) can perform pressure-operated work on the vane rotors and the other ( 97 ) can suck in a working substance through the vane rotors via external force and seal via the chamber rotor into a sleeve ( 47 ).

The chambers ( 52 ) of the Kommer rotors of both machine parts are connected to one another via the channels ( 48 , 51 ) and a sleeve ( 47 ), this sleeve being intended to be heatable via an external heat source ( 101 ) and allowing a working substance to flow through.

The discharge sides ( 77 ) of the blades in the pressure-operated part are connected in a leading manner to the suction sides ( 76 ) of the blades of the compression part, all channels of the blade rotors opening on one side ( 42 ) for the sake of simplicity of arrangement ( 107 ) .

In order to be able to clearly assign the individual phases of the PV diagram, separate each both channels of a pair of blades and rotors have different spaces and therefore different spaces Phases of the process.

An optimal approximation of the course of the state changes is for the fiction moderate machine reached when the positions of the rotors of one machine part at a certain angle, depending on the type of machine and the properties of the medium also shifted up to right angles to the positions of the rotors of the other machine part are what corresponds to a temporal phase shift.

Heat can be extracted from the media-carrying connections of the channels of the wing rotors by means of a regenerator ( 102 ).

Chamber and vane rotors rotate at a gear ratio of 1: 2, and 4 cycle processes take place per full rotation of a chamber rotor.

How it works

In state ( 1 ), the medium is in the space defined by sleeve ( 47 ) and chamber rotors. The beginning of the work in the machine unit ( 98 ) is imminent and is carried out in the direction ( 2 ), ( 3 ) and ( 4 ) until the sleeve ( 47 ) is closed to the chamber rotor. In the direction ( 3 ) in the machine unit ( 97 ) the medium was sucked in from the regenerator ( 102 ) and the volume is continuously increased via ( 4 ), ( 5 ) and ( 6 ). In states ( 7 ) and ( 8 ), the same amount of medium is pushed out of the machine unit ( 98 ) and into the regenerator as is drawn out of the regenerator and into the machine unit. In theory, there is no volume change in these conditions.

Medium is pressed into the regenerator ( 102 ) in the direction of the states ( 9 ) to ( 13 ) while the volume is reduced and the pressure is increased via the vane rotors of the machine part ( 98 ), while the pressure is increased via the compression side of a vane rotor in the machine part ( 97 ) cold medium is pushed into the hot sleeve ( 47 ), which is then closed again in direction ( 1 ).
