Abstract

The invention relates to a hydraulic rotary motor, which operates by exerting only hydrostatic pressure on the contained fluid-dynamic mass. Its rotor (38), has a cylindrical drum (3) consisting of two pieces (3a & 3b) and ending up at both ends of its axis (1), where through bearings (11), it rests on the bases of its shell (8 & 9), with a suitable reception shape. One end of the shaft (1) has a passage (7), through which the controlled intensity hydrostatic pressure of the motor operation is transmitted. Inside the motor drum (3) and in even arcs, there are many vanes (2) attached, each side of which exposes to hydrostatic pressure a different area amount, a small area one (2a) and a much larger one (2b). When exerting hydrostatic pressure, due to this difference in area, a force couple is developed causing a rotational movement, the net force's direction being perpendicular to the sides and from the side of a larger area (2b), to the side of the smaller one (2a).

Description

DESCRIPTION

HYDROSTATIC ROTARY MOTOR

The invention relates to a vane rotary motor requiring for its operation only a certain amount of fluid mass, upon which either positive static hydraulic or pneumatic pressure or negative pressure of controlled intensity can be exerted, which is converted directly into rotary motion.

The well-known vane rotary motors operate through continuous circulation of a certain fluid mass through them, under high pressure and with relatively high energy consumption, secured by an independent pump, forcing the rotor shaft with the vanes mounted thereon in rotational motion.

Based on the principle of energy conservation, but also the principle of hydrostatics that the pressure exerted in a closed container has the same intensity on all parts of its surface and the forces (resulting from these pressures) which are exerted on the surfaces are perpendicular to these surfaces, I then disclose a motor operating at full self- sufficiency, with low force intensity demand, readily available, converting completely ecologically, only static pressure or negative pressure into rotary motion, with absolutely no need for and dependence on a pump circulating continuously and under pressure some fluid through it.

The motor, featuring a very compact volume and a very large ratio of energy output to its volume and weight or mass, has unlimited capabilities and scopes, without requiring use of batteries, fuel and distribution networks. It can also be remotely controlled.

In contrast to the known rotary motors, the vanes of the disclosed motor permanently expose the same constant and unchanging extent or area surfaces, to the exerted static hydraulic or pneumatic pressure, or negative pressure. These vanes are firmly attached and distributed on the inner or outer circumference of the rotor drum, or on both of them. All this is surrounded by a protective housing. Depending on the mounting area of the vanes, the rotary motion can be received: first from the rotor shaft, second from the outer circumference of the rotor drum and third either from the rotor shaft or from the drum circumference, simultaneously or optionally. They are also characterized as single or reversible rotation direction motors. The principle of operation of the motor is as follows. Suppose we have a cylindrical container, in the centre of which there is a shaft carrying attached in two diametrically opposed areas two vanes, both exposed sides thereof having the same surface area. Thus, due to the presence of the two vanes, the toroidal space between the cylinder and the shaft is divided into two semi-cylindrical sectors/spaces or semi-rings on either side thereof. In the case of simultaneously developed pressure of the same intensity, either hydraulic or pneumatic, within these two spaces, no movement will occur because of the same surface area of the vanes exposed to the pressure. Suppose now that we vary the surface area or the exposed surface of the vanes, but only on one side of each of them, by creating a large number of uniform depressions and bumps and on these surfaces, there are smaller similar configurations after the final surface has been submitted to corrosion or sandblast treatment, to eventually look like an orange peel, the other side being perfectly flat and smooth. So, the surface area of the one side of the vanes will be at least four times the other. When installing and fixing the vanes on the carrier or axis thereof, the orientation will be the same, i.e., next to each vane and its smooth surface, there will be the other one with the increased area surface facing the smooth surface of the other. We exert again at the same time, some common pressure in the two sectors of the toroidal space. Now the forces developed on the sides of the vanes are not the same as before, because the product of the common pressure by the total extent/area of the surfaces on which it affects, is different and due to the specific orientation of the vanes, a force couple develops, the direction of the components being perpendicular to the plane of the vanes, or from the side of the vane with a large area, to the side with the small one. That is, the direction of each component force that develops on each vane coincides with the tangent to its centre of symmetry, on which the hydrostatic or pneumatic pressure or negative pressure is exerted. So, if the number of vanes, with similar characteristics and mounting orientation, is increased or multiplied, minimizing the gap of sectors or spaces between them, then the rotational effect will be proportionally multiplied, with the same or less intensity of static or negative pressure. Why negative pressure? Applying static positive pressure causes the movement, in a direction from the side of the vane with the large area to that with the small one, which for the sake of clarification we call: thrust By applying static negative pressure to the sectors between the vanes, the surfaces of the vanes now accepting it develop reverse direction forces, forcing the shaft in a reverse direction rotational movement, this movement called attraction. That is, applying negative pressure (vacuum) causes a reversal of the rotation of the motor shaft. Suppose that as regards the vanes, except for the mounting area or side thereof, the other side does not touch anywhere, but is exposed to the surrounding area of the cylindrical container. What changes then? Just the number of components that make up the motor diminishes, the aforementioned surfaces just also giving the same recommended thrust or rotating effect, causing again the same force couple, while the shaft parts are transferred out of the closed cylindrical container, simply for fastening.

This toroidal ring with the vanes attached to the motor shaft, does not close completely, but has an area - a zone with openings, through which the exerted hydraulic or pneumatic pressure, can affect at the same time all surfaces or sectors of the toroidal ring. The motor can easily cope with the various variables, without the need for large mass flywheels and even without the need for a gearbox, i.e. speed reducer. It goes without saying that the static operating pressure required is minimal, and almost nothing is consumed to develop it

Particular features of the motor are that it works with little sound and almost zero heat operating trace. Its start-up does not require preheating and the maximum output is achieved in a minimum period of time, developing from the beginning of its operation large torque amounts. No cooling or preheating is required for operation.

Also, the motor can, depending on the type of the receiver of the motion produced, have a small or large length, or small/large diameter, i.e., be elongated - axial or discshaped.

Thus, it may be inserted as such, inside the rotor of generators, so that these generators no longer need an external or separate motor to activate. In this way, all current electrical appliances can be made completely autonomous, making them independent of mains connection. Thus, there will be no need for distribution networks and establishment and maintenance thereof, freeing the cities and settlements from the need of presence of unsightly columns and cables, and especially the wooded open areas or steppes, from fire hazards. Indeed, in the form of nanoelectric generators, they can take all forms of batteries, both cylindrical conventional ones and special forms of flat batteries of all electronic gadgets, freeing the devices once and for all from the care of charging, or replacement with charged ones. They can also be inserted into the wheels of all types of wheeled vehicles. Given that they are characterized by large amounts of output or torque, and precisely because of their peculiarity, they can also be inserted entirely in propellers, of either floating or flying means of transport or these propellers may take a special shape, which will contain elements of these hydrostatic rotary motors. Of course, we cannot forget the possibility of their efficient use by unmanned vessels, known as drones.

Also, another important utilization is their use in aircraft engines. These engines can easily drive the turbojet air compressors, freeing them from the waste of fuel required for this purpose. So, after the air compressors have compressed the air, the latter will pass into the chamber - space of the burners and then will come out of the propulsion tube, giving full thrust. In other words, these engines will act like another type of ramjets, which will be activated from zero speed and not only after achieving supersonic speed, as is the case with conventional ones. They will be located in the front part of the air compressor, in the air intake cone from where control/maintenance will be easy while there will be no cooling issues.

In a similar way, they can be inserted into the hub of a vessel propeller, relieving these vessels, regardless of size, of the requirement of a special engine room. With such an application, they also relieve them of the need for a rudder mechanism, since they will be able to change the propeller face angle. And if they are inserted as such inside converging nozzles, giving a new shape and capabilities of Azipod systems, they contribute to a more efficient operation of the whole installation. In addition, in the water propulsion systems of boats with minimal engine room space, they will be an unexpected gift, as these engines will be a single unit with the axial flow propeller or impeller of these systems.

Of course, such engines can also be used in propeller-driven aircraft as well as helicopters, relieving those of the need to use hazardous fuels, while increasing the carrying capacity thereof, without the need for range calculations.

In addition, these engines are the right selection for amphibious vehicles: surface - air, or surface - bottom, due to their light weight, and their simplicity of construction and flexibility of handling, with the simultaneous absence of feed pipes, etc., and nondependence thereof on fuel or batteries.

At the same time, the extension of use in motion and generally in energy output in submarines will relieve the latter of the need for large storage areas for fuel, batteries and even nuclear reactors.

It should be emphasized that the use of these engines relieves the owners/users of> the obligation to pay environmental pollution tax, not being subject to any control of their efficient operation.

These and many more things will be disclosed later, with reference to the accompanying drawings.

Figs, la, lb and 1c, displayed in the same page, illustrate the principle of operation of said motor, as described previously in the introduction. Thus, on the left of the page, Fig. la, where the area of the two exposed sides of the two vanes, under the same pressure (P) is exactly of the same measure, no movement is observed. However, in Fig. lb, next to Fig. la, one side of each vane has a much larger area, compared to the other, the fixing and orientation of the vanes on the axis being the same. Thus, when some pressure is exerted simultaneously on both identical spaces (sectors) of the toroidal ring, defined by the vanes and their position on the shaft, then the product of the area by the applied pressure intensity, on both sides of the vanes with the large area is superior to the other two and rotation will inevitably begin, its direction being that shown by the large arrows in bold, i.e. from the increased area vane surface to that completely flat and smooth. In order for the results to be more efficient, that is, to obtain more easily higher torque - power and speed with lower pressures, the number of vanes shall be a multiple of two. The arrangement of this operation principle scheme can support the manufacture of such a number of motor models, as many as will be presented later for the next category, based on Fig. 1c. But here will be described only those based on the principle of operation of the latter scheme, due to their simplicity of construction. Thus, in this Fig. 1c, the principle of operation of this motor is generally disclosed. It is a cylindrical closed container, in the inner circumference of which or its drum, there are fixed several vanes, the space towards the centre between the vanes being open and allowing the simultaneous communication of all the spaces around it. If a hydrostatic or negative pressure is exerted again in these spaces, the same rotational effects are caused again, due to the difference in exposed area, on the two surfaces of each vane, whose mounting level coincides with their radius of finding. Thus, as in the previous case, the level of development of the net rotational force coincides exactly with the tangent of its level’s radius of finding and the force effect resulting from the applied static pressure. Indeed, this feature is one of the main advantages of this motor, apart from the simplicity of construction. It should also be noted here that the way of increasing the area of a surface, exposed generally to pressure or negative pressure, located in a closed frame, of any shape, as just disclosed, is also a way of making a power multiplier, which is far superior to the known power multipliers, especially TANDEM, while it is also superior in construction simplicity to those.

Referring now to Figs. 2a, 2b and 2c, and especially to Fig. 2a on the left of the page, the whole motor is displayed in side section. In frontal presentation it is clear the difference in the treatment of the planes of the sides of the vanes, where the shaded part is the side of the large area, compared to the flat side, as it will apply in all the shapes of the invention. The way of distributing and mounting the parts that make it up is clearly shown, as well as the ease of choosing the output area of the produced motion, while in the middle and right part of the page, in Figs. 2b & 2c respectively, additional ways of developing the static or negative pressure of the motor operation are presented, in order to reverse the rotational motion. It is also obvious that motion can be received both from the end of the rotor shaft and the outer area of the drum.

Referring now to Figs. 3a, Fig. 3b and Fig. 3c, we see the motor in cross-sectional side view, with the vanes wedged in the inner periphery of the rotor drum, which consists of two parts connected by a thread, while for large units there will be another way of connection, which will also facilitate inspections. Note here that in the case of a large size motor and in order to avoid bending or deformation of the vane shape, it is possible to place radial elements along them, which will support the vanes, against these deformation tendencies. It is noted that the motion outlet to the receiver does not occur from the support shaft, but from the outer periphery of the rotor drum, without excluding the outlet from the end of the shaft. Indeed, in this device, on the outer periphery of the drum, there are mounted the permanent excitation magnets of the modem type self-exciting generator, the armature windings of which surround the excitation. Thus, motor and generator coexist in a single whole, where for ease of inspection or replacement of bearings, the side parts of the housing of the unit are not one-piece, but divided, as clearly shown in the figure. Note that in the outer periphery of the drum instead of the permanent excitation magnets of a modem generator, either a pump or a fen or an air compressor impeller can just as conveniently be mounted. Figs. 3b and Figs. 3c also show in repetition the three different ways of developing and controlling the motor operation hydrostatic pressure, similar to those shown in Figs. 2b, and Fig. 2c.

Fig. 4 shows the same motor model, but having the possibility of reversal, not only by applying negative pressure, but by simultaneously applying positive pressure to one half of the motor and negative pressure to the other half, as will be seen below. This way and this model are chosen for more advantageous results. For this purpose, the rotor consists of two coaxial drums, the vanes being fixed on each drum with a different orientation. Thus, depending on how the piston developing and controlling the intensity of the applied static pressure, or negative pressure, will move in the central area of the rotor of the internal dram, it will compress the fluid medium in the sectors of the one dram and develop a net torque of one direction rotation, and in other ones will cause negative pressure causing a reverse rotational motion. The direction developed on the vanes of each dram will be related to the orientation of mounting of the sides of the vanes, their different area and the type of pressure exerted, that is, whether compression or negative pressure of the fluid medium is applied thereon. Thus, depending on the desired direction of rotation, the control piston will move to fee right or to fee left, inside its cylinder. So, given these features, it can conveniently be placed in fee centre of a wheel of land transport vehicles, or give movement to floating craft propellers, because fee ability to reverse movement without fee interference of other auxiliary mechanisms, is a very great qualification. Indeed, motion can be taken simultaneously from fee end of fee rotor, through a flange but also from fee circumference of fee outer drum of fee rotor, without any problem, serving various purposes. Engines of this arrangement can easily drive catamaran jet propulsion systems due to fee feet feat fee space of fee two side engine rooms of these types of boats can comfortably accommodate them. They can also be conveniently used in azipod systems, which usually contain electric engines, or hydraulic engines, in watertight packaging, which project under fee hull of fee boats, rotating fee propeller, with fee possibility of turning, for steering reasons, by 360 degrees around their support base axis. They are also suitable for the manufacture of outboard engines.

Fig. 5 shows in front view section, the reversible motor of the previous figure, fitted to the centre of a land vehicle wheel. Indeed, it is possible for a motor with a shorter length and therefore lower power, to be mounted on all wheels, which will be controlled by the central body control system, via cables or flexible small diameter pipes, and thus traction will be properly controlled in different forms and conditions of road pavements, as well as in turns or steering of the vehicle. Instead of a wheel, it can also be a special type azipod propeller, or the rotor and impeller of an air, axial flow type, compressor, being placed directly in the air intake cone of an aircraft engine, as mentioned earlier.

Figs. 6a and Figs. 6b show in side view section a particular type of coexistence of a hydrostatic rotary motor with a nanoelectric generator in the shape and size of various known type conventional batteries. Thus, this set can replace all known shapes and sizes of electrical batteries, so that by using such a unit, it is no longer necessary to recharge or replace it with a charged battery. Indeed, if the motor is too short, the unit may take the flat shape of the batteries of all modem small electronic devices, as shown in the following fig. 7. In Fig. 6a, the motor operation hydrostatic pressure control method is shown to be achieved using an electromagnet, while in the next Fig. 6b, control is achieved by using a piezoelectric capsule.

So, in this case, permanent magnets that are the excitation of a modem type generator are shown to be wedged on the outside of the drum, while around the permanent magnets, there are the armature’s windings thereof. The different poles of the battery are indicated by +/- at the ends of the shell. In larger physical sizes, we will have a power bank unit, even portable or permanent generators, of any power amount. It goes without saying that such models or constructions, with theappropriate size, can also be installed in electric cars, relieving them of any care for charging, as well as of the overweight batteries.

Figs. 7a and 7b show in a plan and side view section, respectively, another combination of a hydrostatic rotary motor with an integrated modern nanoelectric generator, in a flat shape, suitable for supplying electronic small appliances. This set can also be made in different sizes, serving various small/large needs. It is an integrated system that includes the self-operating nanoelectric generator as well as the control and filtration system of the generated electricity.

Referring now to those accompanying figures, the preferred embodiment of the invention will be described, making understandable its usefulness, but also its function mode.

We refer again to the figures that make fully understandable the principle of operation of the motor. Thus, on the left side of the page in Fig. la, all the displayed sides (a) of the vanes (2) mounted antidiametrically on the shaft (1) and within the toroidal space enclosed between the outer shell (24) and the shaft (1), appear to have the same surface area. So, by exerting the static pressure (P) in all areas of the toroidal space, no motion change occurs. However, if the vanes (2) are made so that one side of them (b) is full of uniform sinusoidal depressions and bumps and the final treatment of their surface gives the effect of an orange peel, then compared to the others (a), it has four times or more exposed surface area, as shown in Fig. lb, then the product of the applied static pressure, multiplied by the area of each side, gives a larger amount of net force, on the sides (b). So given that the vanes (2) are antidiametrically mounted on a common axis and with the same orientation, the result is the rotational motion, with direction from the side of the vanes (2) with the large area to the side of the small area ones. The directions of the induced forces developed on the surfaces of the sides of the vanes (2) are indicated by the arrows of the figure. The larger and bolder arrows indicate the direction of the induced net force on the sides (b) of the vanes (2), which is superior to that on the sides (a) and which coincides with the direction of rotation of the motor shaft. Fig. 1c broadly discloses the operation principle of the motor type, which will be extensively referenced and explained in the present patent application. It is a cylindrical closed container, in the inner periphery of which, or of its drum (3), there are mounted several vanes (2). The sides of the vanes (2) have on the one view a completely flat and smooth surface (2a), while the other one (2b) is shaped exactly as described in Fig. 2b, full of sinusoidal depressions and bumps with a final surface texture similar to orange peel, so that in comparison with the other (2a), it exposes to the respective static pressures four times or even a larger area. The space towards the centre between the vanes (2) is open and allows the simultaneous communication of all the spaces around it with the static pressures exerted. So, when a hydrostatic or pneumatic pressure is applied to these spaces again, the same rotational results are caused, in the direction indicated by the arrows. These motors can be started either by applying hydrostatic pressure or by applying static pneumatic pressure. These disclosures, however, refer to the use of hydraulic oils, therefore hydrostatic pressure, due to the high degree of "incompressibility" of the hydraulic oils and the greater accuracy of the results of use.

On the left side of the page, in Fig. 2a, the whole motor is displayed in side section. The main element thereof is the shaft (1) of the rotor (38) with two ends, where the rotor (38) is completed by forming a drum split in two parts (3a & 3b). Splitting is intended to have easy access to the inner part of the drum, so that the vanes (2) may be inserted and fastened in special grooves, on the sides (2a, 2b) which will be affected by the hydrostatic operating pressure. The area of the surfaces of the sides of the vanes (2), as described, is not the same. The side numbered (2a), is completely flat and smooth, while the other one (2b), has four times or more exposed area, compared to this of (2a). The two parts (3a & 3b) of the drum are connected to each other via a thread, while a sealing ring ( 15) is inserted between them, so that there is no case of leakage of the fluid operating fluid resulting in deregulation problems. In addition, the left end of the shaft (1) of the rotor (38) and at its bearing point with the elements (11), which are bearings or ball bearings, there are also rubber sealing rings (21), also intended for retaining the operating fluid medium inside the motor. This set of rotors with its bearings or ball bearings are in turn supported on two shells, at the left (8) and at the right (9). In front of the left end of the rotor (38), there is attached (here with a thread) a hydraulic cylinder (5), inside which the piston (4), with the help of a rod (6), can move right or left, inside the cylinder (5). Supposing it moves to the right, then the fluid inside the cylinder (5) will be compressed. This pressure rise through the channel (7) will be transmitted in the interior of the rotor drum (3a, 3b) with the different surface area vanes (2), so depending on the compression intensity a net rotational force will be obtained, from all the vanes (2), with direction from the surface (2b) to (2a). Also depending on the number of vanes (2), the rotational speed that will be obtained, on the shaft (1) of the rotor, will be proportional to the number, the difference of exposed areas of the vane surfaces (2) and the intensity of the applied hydrostatic pressure. If the rod (6) attracts the piston (4) into the cylinder (5), then negative pressure will be induced inside the cylinder (5) which through the channel (7) will be transmitted inside the rotor drum (38) and the exposed surfaces of the vanes (2) mounted therein, now reversing the direction of rotational motion relative to the previous one. The resulting rotational motion can be received, either from the flange (10) at the right end of the rotor shaft (1), or from the outer circumference of the drum, in many ways, here a hub (14) can be seen that may belong to a pump impeller, fan, rotary compressor, etc., or simultaneously from both areas. In the middle of the page, in Fig. 2b, the left part of the motor is shown and the ease of controlling the intensity of its hydrostatic operating pressure, from an external source, through the hydraulic coupling (12). At the right end of the same page, there is another variant on how to control the hydrostatic operating pressure, using a reversible pacemaker or piezoelectric motor, or a rotary hydraulic oscillator (13). Note that both for the motor disclosed herein and for all the rest of the application, if it has a small size, then the elements (11) are thrust receiving ball bearings, which are positioned facing the shaft. If the size is large, then the elements (11) are bearings, and there is a need to place such additional ones, in the form of a ring, receiving axial thrusts, in a suitable position at both ends of the shaft, not designed herein, as easily understood.

At the left of the page, Fig. 3a shows in complete form, in side cross-sectional view, the single hydrostatic rotary motor unit, located exactly in the centre and inside the rotor (38) of a modem electric generator with permanent magnets, which naturally surrounds and is driven thereby. The elements shown in this figure, which have the same reference number as the previous figure, are exactly the same and need no explanatory repetition. The shaft (1) of the rotor in this arrangement does not protrude at its right end and is entirely surrounded by the shell (9). However, as it may be realized, the two shells (8, 9) that support the rotor shaft (38) respectively, for reasons of easy access for inspection or maintenance, are located in the centre of larger shells (16, 17), these end shells being complemented by the middle cylindrical shell (20) to enclose all the contents in a safe operating environment. On the outer periphery of the drum, there is a fixed ring with permanent excitation magnets (18), whose magnetic lines during their rotational motion, in front of the armature windings (19) affect them, causing, as is known in electrical engineering, induction of electric power, that is electric current. In this way, a complete unit of a modem type self-excited electric generator is formed, whose rotor (38) is also its operating motor, without the need to use other external and independent motors, which require for their operation to consume some known form of energy or fuel or take advantage of a volatile renewable energy factor. Figs. 3b and Figs. 3c show in repetition the three different ways of developing and controlling the hydrostatic pressure of the motor, similar to those shown in Figs. 2b and Fig. 2c.

Fig. 4 shows the same motor model, but with the possibility of reversal with simultaneous application of positive pressure in one half of the motor and negative pressure in the other half, as will be seen below, while reversal can also be achieved in the previous model, as mentioned, with an alternative application of negative pressure, instead of positive pressure. But this model may be chosen for more positive results. For this purpose, the rotor (38) consists of two coaxial drums, the inner drum (3c) being attached by a thread to the common body of the right part of the outer drum (3b) which is completed with its left part (3a), which is connected to the right part, again with a thread. The threading method offers a convenience for small units, while for large ones other ways that are more suitable and durable shall be selected. The mounting orientation of the vanes (2), with the special surfaces of increased side area in the two drums, is not the same, the one being opposite to the other. So depending on how the static pressure development and intensity control piston (4) is moved, with the help of its rod (6), which is driven by the element (23), which can be a pacemaker or a rotary hydraulic oscillator (13), positive pressure will develop in the space and on the vanes (2) of the inner drum (3c) when moving to the right into the cylinder defined by the inner walls of the inner drum, while at the same time negative pressure develops at the left part, which is transmitted through the channels (7) to the external drum and the surfaces of the vanes (2) which are mounted therein. In this way the negative pressure that develops in the left part of the cylindrical space of the inner drum (3c), does not remain completely untapped. But this is not the exact reason for designing this device. The reason is the convenience provided to the motor of the type, by reversing the movement of the hydrostatic pressure control piston (4), to enable the immediate reversal of the rotor (38) of the motor, without other complicated ways and servos. Thus, the compressed fluid-dynamic mass through the rightward movement of the piston (4) will exert on the inner surfaces of the inner drum (3c) compression and forces of the same couple on the surfaces of its vanes (2), as in the previous case of Fig. 3a, while on the surfaces of the outer drum (3b) will develop an inverse force couple. Furthermore, in order to avoid displacement of the rubber seal (21) when developing negative pressure in front of it, during the rightward movement of the piston (4), it is held in place with the help of a cyclo-safety (22). So, with these features it can be comfortably placed in the centre of a wheel of land transport vehicles, or give movement to floating propellers, because the ability to reverse movement without the interference of other auxiliary mechanisms is a very great qualification. In fact, the movement can be received simultaneously from the end of the rotor (38), through a flange (10) but also from the circumference of the outer drum of the rotor (38), without any problem, serving various purposes.

Fig. 5 shows in front section the reversible motor of the previous figure, adapted in the centre of a land transport means wheel, forming a single unit. It is mounted to the elements (27), which can be bicycle type forks, or other wheel mounting means of the various means of transport or machine tools. On the outer circumference of the outer drum (3b), with the help of the wedge (25), the wheel (29) is attached, which is located in the radial extension of the rim (28).

Fig. 6a shows in side cross-sectional view an indicative embodiment of the invention, a special type of coexistence of hydrostatic rotary motor - nanoelectric generator in shape and size of various known type conventional batteries. In general, this is a miniature of the unit also shown in Fig. 3a. The difference here lies with the operation control mechanisms. So, also here, the central part consists of the hydrostatic rotary motor, with a simple drum in its rotor (38), to which the ring with permanent excitation magnets (18) of the modem nano-generator is attached, with armature windings (19), which surround the ring (18), also resting by its ends on ball bearings (11), the ball bearings or bearing rings (11) of the rotor (38) at its left end being supported by an intermediate element (36), which is at the same time the nest for holding the annular electromagnet (30) in its correct position. Between the annular electromagnet (30) and the left shell of the unit (8), which is also the positive pole of the battery (+), there is a suitable gap, so that the annular armature (31) of the electromagnet can slide, this armature (31) being kept in close contact with the electromagnet, by means of a spring (32). The left end shell (8) with the positive pole (+), is connected to the central cylindrical shell (20), by means of a thread, as also does the right end shell (9). Conductors-wires run across the shells, represented by thin zigzag lines and terminals (33), located at some key points, connecting the various sections together. Between the socket (36) and the left portion of the shaft (1) of the rotor drum (3), there is a rubber seal (15), to prevent leakage of the operating fluid, the empty frame located in the right part of the unit being a space that will accommodate some elements of electroaccumulation (batteries), so that there is some stock and the motor - generator does not work continuously. The way of activating and starting the operation is as follows: When the accumulation elements are fully or sufficiently loaded, the electromagnet (30), continuously supplied, has the necessary attractive force to hold the armature (31) in contact with it and the spring (32) is fully extended and the left side of the annular armature (31), also serving as hydraulic piston, is in idle position. If the accumulation charge falls to levels where the current supplied to the electromagnet (30) is not sufficient to keep its armature (31) in contact with it and inactivated, then the spring (32) which is an "attraction" spring, attracts the armature (31), which is also the annular hydraulic piston, to the left, which in turn transmits the compression, through the passage (7), to the inside of the drum, affecting the surfaces of the vanes (2) and setting the rotor (38) and drum (3), and the ring with permanent excitation magnets (18), which are attached thereto, in motion, inducing an electric current, which will meet the needs, and will recharge the accumulators located in the blank box to the right of the unit. Thus, this set, with a very small size, can replace all known shape and size electric batteries, so that by installing such a unit, no longer recharging or replacement with a charged battery is needed.

In larger physical sizes, we will have a power bank unit, and even portable or permanent generators, of any power size. It goes without saying that such models or constructions, with the appropriate size, can be installed in electric cars, relieving them of all the care of charging, as well as the multitude of overweight batteries.

Fig. 6b in the same page only shows an alternative embodiment of how to activate the unit, the other elements being the same and unchanged. The difference lies in the use of a piezoelectric capsule (34), which is fastened and held firmly to the base of a cylindrical nest, by means of a ring (35), to the extreme left shell (8) and positive pole (+). The way and reason of activating the capsule and hydrostatic motor is similar to the previously mentioned one, that is, in the case of full charged electric accumulators, the piezoelectric capsule (34) remains curved at the maximum bending arrow. As soon as the capsule (34) supply current is reduced or zeroed, then this capsule (34) loses its curvature and contracts to the right of its cylindrical nest, thus forcing the fluid dynamic means into compression, where through the known passage (7), it will end up acting inside the drum (3) of the rotor (38) with its vanes (2) and other elements in rotational motion and generation and storage of electricity.

In Fig. 7a, at the top of the page, the whole body of a device is shown in plan section, the device being a stand-alone unit, which has different sizes, as is the case of the various flat batteries of electronic devices. In its left space there is a complete self- propelled nanoelectric generator, at the top and in the centre thereof being the hydrostatic rotaiy motor, next to the motor drum, there is a fixed ring with permanent excitation magnets (18), whose magnetic lines during rotation, affect the armature windings (19) shown in Fig. 7b, inducing an electric current therein. In the centre, there is shown the hydrostatic motor, with the special configurations of the sides of its vanes (2a and 2b), and the development and control piston of hydrostatic operating pressure (4). The space (37) under the motor is available for the control of the motor operation and the rectification and filtration of the generated electricity, while in the other space (26), there is a system of a minimum accumulation of electricity, to operate the memory and to avoid continuous operation of the nanoelectric generator. At the bottom of the page, in Fig. 7a, the above unit is displayed in side cross-section. On the left side of the page, in addition to the sections already mentioned, the shape of the piezostatic capsule (34) is displayed, which when the small battery is fully charged or no output and power supply to perform tasks is required, will cease to be powered and thus due to its structural property it will bend upwards, forming the arc shown in the drawing, dragging the piston attached to it (4), which in turn releases the inner space of the drum (3) from the hydrostatic pressure and thus stops the motor operation. Thus, the motor and generator stop operating. The capsule (34) is attached to the housing of the unit with the ring (35), the cylindrical part of the drum in its centre, together with the bearing (11), contributing to good support of the motor - generator. Note that the measures in this figure do not correspond to the real ones, which are much smaller, used only for clarity reasons. It is therefore noted here that the description of the invention was made with reference to illustrative examples of application, not being limited thereto. Thus, any change or modification regarding the shape, size, dimensions, materials used and components of construction and assembly, variety of fields of application, as long as they are not a new inventive step and do not contribute to the art already known, are considered contained in the purposes and aspirations of this invention.
