Broadly speaking, the invention belongs to the field of: driving machines, turbines, engines, pumps, and more narrowly: machines or driving machines, turbines, engines, pumps, with a rotary piston, according to the International Classification of Patents MKP (2006.01), the subject of the invention is classified or classified and marked with the classification symbols F01C 1/00, F02B 55/00, F03C 2/00, F04C2/00, F04C 11/00, F04C 18/00, F04C 23/00.

Technical problem

The technical problem solved by this invention consists in the following: how to structurally solve a device with a rotary piston (pistons) in several ways of execution that could be used wherever there is a need for the following purposes; creating a vacuum, compressing compressible fluids, pumping fluids, creating high and extremely high pressures; vacuum devices, compressors, pumps, then for driven and driven hydraulic - pneumatic machines; devices that have the ability to convert the energy of a fluid into mechanical power and vice versa (turbines, engines,...).

By applying structural assemblies with mutually coupled gears and rotary pistons of different profiles, a simple economically acceptable construction with a high degree of utilization and a long working life is achieved, with which they are significantly reduced; friction, noise, and achieves maximum torque and resistance to very high operating pressures.

State of the art

Various constructions of driving and driven machines are widely known, the main disadvantage of which is expensive and complicated production, as well as bulkiness. With most of the known constructions, the main problem is the expensive construction, the need for constant lubrication due to the high coefficient of friction, which entails expensive lubrication systems, and they also have a low level of fluid energy utilization, e.g.; compressors (classic reciprocating) whose construction is complicated, relatively expensive and very noisy, then; pumps with a larger number (2,..., 10, ...and more) of impellers used to achieve higher pressure, which makes them bulky and expensive, as well as high-pressure pumps of 100...200 Bar, expensive and complicated; steam turbines for which it is necessary to hire special engines at the very start; vacuum devices with a very high speed of rotation of the working wheels and a low degree of achieved vacuum; SUS engines - very complicated.

Exposition of the essence of the invention

The rotary pistons in the housing, with their upper and lower flat surfaces, are located on the line of contact with the surfaces of the partition wall or cover, which close the housing of the pistons as well as the pistons themselves (and they can be with larger clearances when used for fluids with impurities); rotary pistons are rigidly connected to gears via shafts, which are located in another housing (with a certain amount of oil, sufficient for their lubrication) where they are mutually coupled; a drive gear with one or more driven gears aimed at transmitting power and matching the rotation of the rotary pistons; rotating rotary pistons slide with their tips (on the very contact line) on the inside of the piston housing (and they can be with larger clearances when used for fluids with impurities) creating a negative pressure behind them (a certain degree of vacuum) and in front of them exert pressure or they are pushed (when the device is in the function of a turbine or engine, etc.); a certain amount of oil may be present in the housing with pistons in order to enable more complete sealing and (there may also be a constant flow of an appropriate amount of cooled oil which would aim, among other things, to cool the device if needed) greater efficiency when using the device for the function of a vacuum pump or compressor. - The rotary piston consists of a cylindrical-semi-cylindrical body that has a cylindrical-semi-cylindrical or other shaped protrusion(s) and a cylindrical-semi-cylindrical or other shaped groove(s).

Longitudinal protrusion(s) of a cylindrical - semi-cylindrical or other shape on the body of the rotary piston, parallel to the axis of the body of the rotary piston, for easier identification, each shape is specially marked with one of the following letters of the alphabet, namely; "A" ,,B" ,,<C>" ,,D" ,,E"

"F".

- "A" is a cylindrical-semi-cylindrical protrusion.

- "B" is a protrusion in the form of a stepped (longitudinal) cylinder-semi-cylinder on one side. - "C" is a protrusion in the form of a stepped (longitudinal) cylinder-semi-cylinder, one on both sides. - "D" is a protrusion in the form of a stepped (longitudinal) cylinder-semi-cylinder twice on both sides. - "E" is a protrusion in the form of a stepped (longitudinal) cylinder-semi-cylinder four times on both sides.

- "F' is a bulge in the form of a hemmed cylinder-semi-cylinder.

Longitudinal groove(s) of cylindrical-semi-cylindrical or other shape on the body of the rotary piston is (are) parallel to the axis of the body of the rotary piston, for ease of recognition each shape is specially marked with one of the following letters of the alphabet and that; "G" "H'\

- "G" is a cylindrical-semi-cylindrical groove.

- "H" is a groove in the form of a hemmed cylinder-half cylinder, adapted to the shape of the working piston "F". The protrusion or groove, as well as multiple protrusions and grooves (or combined) of any shape (A, B, C, D, E, F, G, H) on the body of the rotary piston, are classified for easier description into the following; grooves alternately arranged at angles of 90 degrees.- Double-sided working rotary piston is a body of cylindrical-semi-cylindrical shape with a shaft opening in the center or with an equal shaft, on which two protrusions are arranged at an angle of 180 degrees.- Double-sided auxiliary rotary piston- is a body of cylindrical-semi-cylindrical shape with a shaft opening in the center or with an equal shaft, in which two grooves are arranged at an angle of 180 degrees.- One-sided working rotary piston- is a cylindrical-semi-cylindrical body with a shaft opening in the center or with an equal shaft, on which there is one bulge.- One-sided auxiliary rotary piston_- is a cylindrical-semi-cylindrical body with a shaft opening in the center or with an equal shaft, in which there is one groove.- Three-sided working rotary piston - a cylindrical-semi-cylindrical body on which three protrusions are arranged at angles of 120 degrees.- Three-sided auxiliary rotary piston- is a body of cylindrical-semi-cylindrical shape with a shaft opening in the center or with an equal shaft, in which three grooves are arranged at angles of 120 degrees.- Four-sided working rotary piston - is a body of cylindrical-semi-cylindrical shape with a shaft opening in the center or with an even shaft, on which there are four protrusions arranged at angles of 90 degrees .- Four-sided auxiliary rotary statue- is a body of cylindrical-semi-cylindrical shape with a hole for the shaft in the center or with an equal shaft, in which four grooves are arranged at angles of 90 degrees.

The body of the rotary piston, which is of a cylindrical-semi-cylindrical shape made equal to the shaft or with an opening in the center that corresponds to the diameter of the shaft, can have protrusions of any form A, B, C, D, E or F, and grooves of the form G or H, individually or combined by several protrusions and grooves, which is shown and explained in figures 138 to 141, then figures 143 to 174 and in devices from the figure 1 to 137.

Grooves - channels are made inside the housing of the pistons on the partition wall and the cover, that is, the elements that close the pistons on both sides. And that around the sealing elements themselves (holes for the shaft or bearings), with the outlet towards the inlet (fluid into the device). Channels or grooves that can be of different dimensions, shapes, diameters and profiles. they must be aligned with the device in question, that is, with the dimensions of the body of the piston that is in the given device. And so that it fully satisfies its purpose without reducing the stability and efficiency of the device in question. This is done in order to relieve the burden; sealing elements, shaft openings and bearings (which are located in partition walls and covers) from the pressure of the fluid in the device are extremely important, especially at high and extremely high pressures.

Devices with rotary pistons are dimensioned so that there is a certain gap between the pistons and the inner surface of the piston chamber through which the piston moves, as well as between the bodies of the rotary pistons themselves. In such cases, the efficiency of the device is reduced to a certain extent, but the advantage of this solution is that the device can be used for work with fluids that have impurities in them (such as sand or some other impurity in water or any other fluid with any kind of impurity).

The invention can be used as a brake by simultaneously and evenly closing (opening) the drain and supply valves and thus reducing (increasing) the fluid flow (liquid fluids are the most effective for this purpose), thereby reducing (increasing) the speed of rotation of the shaft or it stops completely at the moment of complete closure of both valves. This would avoid the friction braking method used in some braking systems.

The invention - a device with rotary pistons can also be used for internal combustion engines, primarily gas SUS engines, by opening the valve in a certain position of the pistons, on the input (connecting) sides of the piston housing and thus allowing the mixture of air and fuel to be brought into a certain space of the piston chamber under a certain pressure sufficient for that function, and then immediately after closing the valve, the mixture would be ignited with spark plugs or in any other suitable way, and all this is repeated when every revolution. Determining the moment of opening and closing the valve as well as the moment of ignition of the mixture would be done electronically, mechanically or any other way suitable for that purpose.

The advantages of this invention are mainly contained in the facts; to completely avoid complicated transformations of rectilinear to circular motion and vice versa; that the device with this type of rotary piston achieves maximum torque; that devices have even operation and greater efficiency (higher utilization percentage) because they do not idle; that the noise is less; that the shapes of the rotary pistons, one and more stepwise notched protrusions on one or both sides prevent the occurrence of additional loads on the shafts during rotation, especially at higher speeds; that the auxiliary grooves on the mutually coupled rotary pistons in their housing, in operation, enable the smooth transition of the working protrusions from the overpressure zone to the underpressure zone without loss (that is, with very small losses that are negligible); that there is no direct contact of the pistons with each other or with the housing, which avoids mutual friction (wear) and thus extends the service life; that the rotary piston (which is true for most of its forms and depends on the function it performs) is equally effective whether it rotates in one direction or the other; that there is no need for complicated lubrication systems; that inside the piston housing on the partition wall and the cover, i.e. the elements that close the pistons on both sides, there are grooves - channels around the sealing elements (shaft opening or around the bearing), in order to accept the amount (this is a very small amount that would slip between the partition wall-cover and the pistons during operation) of fluid from the part of the piston housing where overpressure prevails and direct the outlet to the part of the piston housing where there is underpressure (ka inlet part) this is of extreme importance, especially at high and extremely high pressures in order to protect the sealing elements and bearings as well as to prevent the penetration of fluids into adjacent housings or outside.

According to the invention, rotary pistons are with protrusions and grooves of different shapes (shown in pictures from 138 to 174 and in devices from pictures 1 to 137), and their selection is made depending on the purpose and type of fluid for which they will be used.

In the following (sketched) four cross-section examples, an explanation is given for the execution of the four basic forms of (working) protrusions and two basic forms of (auxiliary) grooves together with the body, according to which all the forms used in devices on si are derived. 1 to 137 and pictures 142 to 1 74.

Body 6 with working projections A and auxiliary grooves G, shown in fig. 138, they are made so that the body 6 has a circular cross-section with a radius R and a central circular opening of radius Rl (if the body and the shaft are made equal, then Rl corresponds to the radius of the shaft). Along the longer axis, two semicircular (working) protrusions A with radius r and height v are made, and vertically on the shorter axis, two symmetrical semicircular (auxiliary) grooves G with radius rl and height vi. All the mentioned parameters are variable in order to match the needs (technical characteristics) for which the device with rotary pistons will be used.

Along the longer axis, there are two semicircular stepped incised on one side, radius R2 for height v2, (working) protrusions B with radius r and height v, and vertically on the shorter axis two symmetrical semicircular (auxiliary) grooves G with radius rl and height vi. All the mentioned parameters are variable in order to match the needs (technical characteristics) for which the device with rotary pistons will be used.

Along the longer axis, there are two semicircular stepped paths cut twice on both sides, with radii R2 and R3 for heights v2 and v3, (working) bulges D with radius r and height v, and vertically on the shorter axis two symmetrical semicircular (auxiliary) grooves G with radius rl and height vi.

A general explanation according to the invention, whether it is about an assembly that has two or more gears connected via a shaft with two or more bodies (with working or auxiliary grooves), about the way it functions, which is valid for all variant solutions, would be as follows; Bodies 6 with (working) protrusions A,B,C,D,E or F and auxiliary (grooves) G or H, in a word Rotary pistons in piston housings 11-lla, with their upper and lower flat surfaces are located on the line of contact with the inner surfaces of the partition wall 7-7a and the cover 1-1a, which close the pistons (and can be with larger clearances when used for fluids with impurities); bodies 6 are in a rigid connection (or made equal to the shafts) via shafts 4-5-5a with gears 10-10a which are located in the housing 9 of the gears (in which there is a certain amount of oil, sufficient for their lubrication) where the driving gear 10a-10 are mutually coupled with one or more driven gears 10 and have the purpose of transmitting power and matching the rotational speed pistons, whereby the piston housing 11-lla and the gear housing 9 are separated by a partition wall 7-7a on which there are openings through which the shafts 4-5-5a pass; rotating together with the telorn 6 (working) protrusions A,B,C,D,E, or F slide with their tips (on the very line of contact) on the inside of the housing 11, 11a of the pistons (and they can be with larger clearances when used for fluids with impurities) creating a negative pressure (a certain degree of vacuum) behind them, and in front of them they push or they are pushed (when the device is in the function of a turbine or engine, etc.) ; auxiliary grooves G and H are intended to enable the smooth transition of (working) protrusions from the overpressure zone to the underpressure zone during operation and at the same time prevent the penetration of fluids from the overpressure zone to the underpressure zone; a certain amount of oil may be present in the housing (11-lla) of the pistons in order to enable more complete sealing and greater efficiency (there may also be a constant flow of an appropriate amount of cooled oil, which would aim, among other things, to cool the device if needed) when using the device for the function of a vacuum pump or compressor; the inlet-outlet connections 20 on the piston housings 11 or the rear cover 1 are of different shapes or round with a thread, so that the installation connections can be screwed into them.

Achieving a rigid connection between the body 6 of the rotary pistons and the shaft 4-5-5a, i.e. the gear 10-10a and the shaft 4-5-5a can be achieved in any known and suitable way. They can be made equally: body 6 with shaft 4-5-5a or gear 10-10a with shaft 4-5-5a. Bearings 2, where the shafts are mounted in assemblies, can be of all types and are selected according to dimensions and endurance to the required loads as well as endurance to certain temperatures and according to the way they are lubricated, depending on the need for what the specific device will be used for (ball, roller, needle, sliding and other bearings...)

The shafts 4-5-5a of the device, on which there are bodies 6 with pistons and gears 10-10a, are inserted into; the middle partition wall 7 and the rear cover 1-1a, which close the housing of the pistons as well as the pistons themselves; then inserted in the middle partition wall 7 and the front cover 12 that close the housing 9 of the gears; inserted in the front cover 12 and the back cover 1; inserted only in the partition wall 7 that separates the housing 9 of the gears from the housing 11 of the pistons. In some cases of making a device together with a drive motor (or generator), the extended shaft of that motor (or generator), which is already mounted, can be used to carry one rotary piston and one gear in the given device.

In all assemblies, the sealing elements 8 are selected according to the type of fluid, then depending on their resistance to pressure and heat to which they are exposed and can be of all types (suitable for the desired assemblies).

Depending on the type of material, the intended purpose and the required usage characteristics of the device such as: fluid flow rates, types of fluid, fluid pressures (small-high or extremely high) and the heat that the fluids have or generate during operation, are determined: types of material: all dimensions of the housing of 11-lla pistons; all dimensions of partition walls 7-7a; all dimensions of rear covers 1-1 a ; all body dimensions 6; all dimensions and shapes of working protrusions (A, B, C, D, E, F) and auxiliary grooves (G, H); all shaft dimensions 4-5-5a; all dimensions and types of gears (10, 10a) which can be of any type and for the given devices of the appropriate shape; as well as all dimensions of the type and number (for example, high pressure assemblies require a greater number of screws and vice versa) of all others, for given assemblies of selected and mutually coordinated elements that correspond to the set requirements.

Elements of the device assembly; rear covers 1-1 a piston housings, front covers 12 gear housings, partition walls 7, gear housings 9, housings 11-1 la pistons, are made each separately or by several elements equal to; rear cover 1 equal to piston housing 11-1 la ; the front cover 12 is equal to the gear case 9; partition wall 7 is flush with gear housing 9; partition wall 7 is equal to housing 11 pistons, this is significant due to the choice of production methods, in order to choose the most favorable one for the intended assemblies.

Interconnection of all parts (housing, covers, partition walls,) into a solid assembly can be achieved in all known and appropriate ways for the given assemblies.

Assemblies can be composed of elements (piston, housing, partition wall, cover...) made of different types of materials (alloys) or a combination of dvc and several types of materials. Let's take for example that the pistons can be partially or completely made of some type of rubber that would be able to amortize during operation (up to a certain size) the possible presence of some foreign bodies (solid impurities) in the fluid.

Inside the housing 11-lla of the pistons on the partition wall 7-7a and the rear cover 1-1a, i.e. the elements that close the rotary pistons on both sides, channels 25 are made (see devices according to the second and third methods of execution) designed in a circle around the sealing elements themselves 8

and around the opening for the shaft, i.e. bearing 2, with an outlet towards the connections 20 (for fluid entry into the device), and they can be of different dimensions, shapes, diameters and profiles adapted to the device in question. And so that they fully satisfy their purpose without reducing the stability and efficiency of the given device. Making grooves or channels is recommended for all devices. This is done in order to relieve - protect the sealing elements 8, the shaft opening 4 and the bearing 2, which are in the partition walls and covers from the pressure of the fluid in the device, which is of extreme importance, especially at high and extremely high pressures.
