    image3 DESCRIPTION OF THE INVENTION
    The rotary engine that is recommended solves in a fully satisfactory way the problem previously exposed in each and every one of the aspects mentioned.
    5
    To do this, and more specifically, the engine of the invention is constituted by a stator, materialized in a hollow cylinder, in which a rotor plays eccentrically, and in its turn it draws four articulated parts or oscillators, in housings arranged at the ends of perpendicular diameters of said rotor, on whose parts they support and
    10 slide others depending on pistons, which rotate concentrically to the main stator cavity.
    Each of the articulated ones has a protrusion in the form of a circular groove, which is housed in a rotor channel, and the four pistons, in a rectangular prismatic shape, have 15 protrusions in the form of a circular sector with grooves that receive guide washers, whose projections, arranged on both sides of each piston, carry, internally and externally, mounted other washers, which are coupled in lateral cavities in the form of a circular crown of the stator, so that the four pistons divide the cavity between the rotor and the stator in four other cavities, which turn that continuously vary from
    20 volume
    The pistons and sealing segments as well as the stator will be obtained in aluminum.
    In the part of greater separation between said stator and rotor, the exhaust and intake ports, successively adjacent, are arranged in the direction of rotation.
    According to another of the characteristics of the invention, it is envisioned that in the stator, four injectors are established that converge on the same area that defines the
    30 combustion chamber in the eccentric rotation of the rotor within the stator, generating chambers of variable volumetry in which the process of admission, compression, combustion and exhaust occurs.
    image4
    A circular radiator is attached to the engine, forming a single piece, which has a cavity in that way that concentrically houses a centrifugal compressor, consisting of two parts: one of smaller diameter, located at the inlet, which produces and throws air through of a set of circular tubes that surround it, and through which oil circulates, which cools, and the other, of greater diameter, that compresses the air that feeds the engine, both of which are mounted on the same axis, axis also associated with the rotor , and that it can rest, indistinctly on bearings or on bearings.
    On the other hand, the pistons have externally fitted parts that form a box, which covers its main projection, acting as a function of sealing segments, in addition to the conventional segments of the articulated parts.
    As for the stator, in all its contour, at regular intervals, cameras are arranged through which the coolant circulates, surrounding the main cavity of the stator that houses the incandescent gases.
    The radiator incorporates a first zone of hollow circular rings that surrounds the compressor and through which greasing oil circulates to cool, this area is separated from the second by a chamber, to which air arrives through three tubes located in a plane perpendicular to the motor shaft, radially at 120º, coming from the compressor and intended to cool the engine coolant.
    The oil is driven by a pump associated with the rotor shaft, arranged in series between the compressor and the radiator.
    In parallel, inside the main projection of each piston, a stream of refrigerated oil circulates, while the rotor has internal cavities, through which also refrigerated oil circulates, this oil is also circulated through conduits made in the rotor , oscillators and rotor shaft.
    Consequently, the engine includes the following main elements arranged parallel to each other along the imaginary axis of rotation of the rotor: engine block compressor-injection pump-oil radiator-water radiator.
    image5
    Additionally, it is provided that the engine includes a turbocharger, which runs parallel to the mechanical compressor, so that the gases that exit through the exhaust port 5 are passed through a turbine whose axis drives a compressor that feeds parallel to the intake to the intake port.
    Said assembly will have a discharge valve to avoid excessive intake air when it is not necessary.
    10
    The engine described in this way is applicable to cars, trucks, buses, marine, aviation, railways, public works machinery, agriculture, etc., with a useful life far superior to that of current engines.

    In view of the figures outlined, it can be seen how the rotary motor that is recommended is constituted by a hollow cylinder, determining the stator (1), within which another cylinder rotates, eccentric with that, determining the rotor (2).
    Four oscillators (4) are arranged in the rotor 2 (see fig. 15a), within which pistons (3) slide and rest, which perform a function equivalent to that of these elements in the known alternative motors.
    The four pistons rotate concentrically with respect to the circular cavity 41 (fig. 8), fitting perfectly inside it.
    On the other hand, the oscillators (4) incorporate a projection (16), which is introduced into a channel of the rotor (2), preventing such parts from leaving due to the centrifugal force of their location. In addition, they are articulated in holes (19) of the rotor (2) by which this oscillating character is achieved.
    Each of the four pistons (3), has two projections (fig 14), in which there are two grooves (14), in which washers (5) are inserted. Figures 10a, 10b, 10c and 10d show different views in profile and elevation of two of the pieces (3 ’) that are used to assemble the pistons.
    Inside and outwardly to these projections of the pistons (3), there are two other washers (6) (figs. 8 and 9). These projections, arranged on both sides of each piston (3), with their respective washers (5) and (6), are interspersed in two lateral cavities, practiced in the stator.
    image8
    The rotor assembly (2), pistons (3) with their respective washers (5) and (6), and oscillators (4), rotate inside the main stator cavity. The pistons (3) rotate concentrically 5 with respect to said main cavity 41 (fig. 8), and the rotor (2) does it eccentrically with respect thereto.
    Said rotor is attached to the shaft (11) (fig. 4), which is supported by bearings (18) or bearings (18 ’) (figs. 1 and 3). The shaft (11) internally incorporates ducts (11 ’), by
    10 that cooling oil is circulated.
    The recess 28 (fig. 11a) is where one of the axle heads is housed, and the other end thereof is housed on the other side of the stator.
    15 As a result of the rotation of such a set, the cavities K, M, N, P (fig. 8) between the stator, the rotor, and the corresponding pistons, which house the gas as they are, are increasing or decreasing at the same time. details in the explanation of the operation.
    The pistons (3) carry the pieces 21 (fig 14c) externally placed in lace
    20 practiced in them, forming a kind of box, which externally covers the main protrusion of the piston, making segments.
    In addition, of these pieces in function of segments, there are others indicated (10) in figure 8, which adjust laterally, and also those (9) and 17 (fig 6a), which fit into the groove
    25 of the piece (4), fit against the side walls of the piston (3) and with the rotor (2).
    The intake port (7) and the exhaust port (8), visible in Figure 9, are located in the part where the separation between the rotor and the inner part of the stator cavity is maximum.
    30 From this structuring, four combustion chambers (29) (figs 1 and 3) are located located on the outside of the rotor and separated 90º from each other.
    image9
    By means of four injectors (30) a jet of fuel is injected into these chambers, where there is high pressure and temperature air.
    The stator is equipped with refrigeration chambers (12), through which the coolant (water or equivalent) circulates, and which, being distributed around the main cavity (41) of the stator, manages to limit the heat produced in it by effect of the combustions that are continuously being verified.
    The engine has joined, forming a single piece, the radiator.
    The compressor is centrifugal type, consisting of two parts: one (34) of smaller diameter, responsible for producing air and throwing it through the circular tubes (39), to cool the liquid that circulates through them; and the other, (35) of greater diameter (the two coaxiles), which is responsible for producing air at a certain pressure, to sweep gases and at the same time fill the cavities to perform another complete cycle.
    The radiator tubes (39) are ring-shaped and are placed perpendicularly to the diametral plane of the engine. In addition, they are concentric with the motor shaft (11) and with respect to the compressor (34).
    The radiator has two concentric zones of these rings: the first one that surrounds the compressor (34), and the second one that in turn wraps the first one, separated by the chamber
    C.
    With regard to the air released by the compressor (34): a part is sent through the first group of rings, and these cooled, is expelled through the pipe B to the outside, which air can be used in heating; the other part is introduced by means of three tubes E, placed radially and separated 120 ° from each other, to the chamber C, in which, through the second ring zone, and after cooling, it is ejected to the socket general D, which can also be used for heating.
    In addition to the cooling system of which the chambers (12), described above, are part, the rotor (2) has conduits (2 ’) (figs 6a and 6b), through which a current of oil circulates that serves to cool it. Also in each piston (3) refrigerated oil circulates internally, through conduits (3 ') (figs. 7a to 7c), which being said pistons always in contact with the walls of the stator cavity, they receive the heat of the high temperature zones and drag it towards the zones of
    image10
    5 lower temperature, and thus a perfect thermal equilibrium is achieved throughout the main cavity (41) of the stator. In Figure 5a it has been referenced with (2 ’’) the hot zones of the rotor and with (2 ’’) the cold areas.
    As combustions are always carried out in the area of the injector, in that part the
    The temperature would increase significantly, if it were not for this current of oil that exists in the pistons, in collaboration with the external cooling by means of the chambers (12).
    The lubricating oil, which is also cooling, is cooled in the first group of 15 rings surrounding the compressor (34).
    Finally, the stator closes with a ring (31), incorporating recesses (32) to lighten the motor.
    20 As regards the operation of the described engine, due to the rotation of the set of parts (2, 3, 4, etc.), the cavities N, P (fig. 8) are increasing and decreasing at the same time. that the gas is located before or after the inflammation of the fuel.
    25 By using the different types of segments described above, all types of communication between cavities that house incandescent gases and greasing oils are eliminated, while preventing pressure loss.
    The engine performs a duty cycle that can be considered four-stroke, since
    30 consists of intake, compression, combustion and exhaust, for which purpose it is provided with the mentioned intake ports (7) and exhaust (8).
    In the combustion chambers (29) (figs. 1, 3), at the time of combustion, all the air in the cavity N is housed and the fuel is injected through the four injectors (30).
    image11
    In more detail, when turning the rotor (2), of the four cavities of the engine, some are increasing their capacity, and others decreasing it.
    As for the cavity K in said figures, the exhaust port (8) has just been discovered; that cavity finishes carrying out a complete cycle and is currently carrying out the expulsion of combustion gases into the atmosphere;
    Then, when the rotor has rotated 45 °, that cavity K changes in volumetry and position, and in the center of that cavity are the exhaust ports (8), and (7) of intake; by
    (8) exhaust flue gases are expelled into the atmosphere;
    At the same time that the expulsion of gases takes place, from the cavity K by the port (8); through the (7) in the same cavity, the air coming from the atmosphere enters, which the compressor (35) sends through (37) to fill it again with pure air;
    When the rotor rotates another 45 °, the cavity K is filled with atmospheric air;
    By rotating the rotor 90º more, the cavity reduces its volume and compresses the air it encloses.
    When turning that cavity 45º more, it takes a new form leaving the compressed air at a high pressure and temperature. At that time, in the gaseous mass that is at high temperature inside the combustion chamber (29), it is injected by the injectors
    (30) a jet of fuel, which ignites almost instantaneously when penetrating into that atmosphere of very hot air, and immediately the temperature and pressure increase in large proportion;
    When the rotor (2) has turned a little more, one of the pistons protrudes; and the cavity acquiring the form indicated in P. In such a position, the pressure of the gases affects that protruding piston, which is indicated in the cavity P and forces the rotor to rotate.
    image12
    At that moment, after having carried out the corresponding work, the combustion gases are expelled into the atmosphere, and at the same time, repeating the cycle again, the compressor returns air to enter the intake port (7).
    The same that has been explained for the chosen cavity, occurs with the remaining three, thus producing four cycles of work at each turn of the axis.
    As regards greasing, it is carried out by means of a conventional type pump, with the ramifications corresponding to all the points of the engine that are deemed necessary, whose installation has a radiator to cool the oil.
    The engine will include four injectors (30), in order that the injection system does not overload.
    As for cooling, the corresponding liquid enters through the part where the injector is located, which is the hottest and comes out on the opposite; thus, it is achieved that the heat accumulated in the part of the injector, is transferred to the opposite place, balancing as far as possible the temperatures of the entire engine.
    The filtering of the combustion air with which the engine is fed is carried out by passing through the compressor (34) and into the radiator, the solid particles that the air contains being expelled by the centrifugal force, through the rings ( 39) of the radiator, from where the force of the expelled air passes through pipes outside.
    In figure 16, the aligned and parallel arrangement of the main elements of the motor, arranged along the imaginary axis of rotation of the rotor, and which are motor block (50), mechanical compressor (51), pump can be observed in general injection (52), oil radiator (53) and water radiator (54).
    Additionally, it is provided that the engine includes a turbocharger (55), which runs parallel to the mechanical compressor, so that the gases leaving the exhaust port are passed through a turbine (56) whose shaft (57) drives a compressor (58) that feeds in parallel at the intake to the intake port, with a discharge valve (59) to avoid excess intake air when it is not necessary.
    image13
    5 As for the alternator (60), it will be arranged in front of the turbocharger, defining in its power take-off a horizontal axis (61) that extends to the start of the engine, with a vertical bending (62) that extends until reaching the motor shaft.
    In figure 17 the relationship between the oil radiator (53) and the hot (C) and cold (F) parts of the engine has been schematically represented,
    With minor modifications the engine can run on both diesel and gasoline, butane, biofuel and hydrogen.
    15 By way of example, three ideal engine models are planned.
    The first, whose axis would support on bearings would have a displacement of 4x622cm3 = 2488cm3, capable of working at 3000rpm, with a torque of 970Nm, a power of 406.5 hp, a mechanical performance of 82.56%, a thermal efficiency of 44.66% and a yield
    20 43.87% total.
    The second, whose axis would support on bearings, would have a displacement of 4x622cm3 = 2488cm3, capable of working at 3000rpm, with a torque of 970Nm, a power of 406.5 hp, a mechanical performance of 89.5%, a thermal performance of the
    25 44.66% and a total yield of 46.7%.
    In parallel, the engine power could be expanded to 490 hp simply by increasing the displacement to 3000cm3.
