Abstract

The invention relates to a balanced rotary engine consisting of a rotary engine comprising tangential pistons which improve engine performance, facilitate the lubrication of the engine components, enable the use thereof at high revolutions and condition same for two-stroke operation with full use of the combustion chamber, even with mixtures (diesel cycle) which explode spontaneously upon reaching high compressions with a suitable volume. According to the invention, the components are structured such that (i) the engine can also be self-powered and (ii) the air or mixture is drawn directly from the rear of the cylinder and, subsequently, injected into the combustion chamber of said cylinder or of the cylinder adjacent thereto.

Description

 BALANCED ROTARY ENGINE.

Object of the invention. The present descriptive report presents a balanced rotary engine based on a rotary engine of tangential pistons, which improve its performance, facilitate the lubrication of its elements, allow the use thereof at high revolutions. The conformation of its elements allow it to be self-powered and the air or mixture to be sucked directly to the rear of the cylinder and then injected into the combustion chamber of the same or adjacent cylinder and conditioned to be used in two stages with full use of the combustion chamber, even with spontaneous explosion mixtures (diesel cycle) to achieve high compressions with an adequate volume.

BACKGROUND OF THE INVENTION The two-stroke engines developed to date are based on the use of nozzles for the admission of the comburent-fuel mixture, practiced in the cylinder, which significantly reduces the effective chamber, the time of entry of the mixture, the sweep of gases and engine compression, so it loses effectiveness and does not make it suitable for the use of spontaneous explosion mixtures. Likewise, the tangential piston rotary motors, currently in development, have the opposite pistons coupled to the same crankshaft pin or crank so that, during the rotation of the assembly, the movement of the internal elements (pistons, rods and articulated lever) it is not symmetrical, producing charges that cause vibrations. In the same way, these are housed in a single chamber, which makes it difficult to lubricate them when the agent used for this purpose is moved to the outside thereof, driven by the centrifugal force. It is unknown on the part of the applicant, skilled in the art, of any self-powered and balanced rotary motor as described below. Description of the invention. In order to alleviate or eliminate the aforementioned problems, the rotary self-powered and balanced motor, object of the present invention patent, is presented. In the present invention it has been chosen to couple the pistons of each cylinder a journal of the crankshaft displaced the same number of degrees as these and dividing the chamber containing the internal elements in several watertight compartments, a central one where the crankshaft is housed and the part ribbed of the articulated lever and another outside for each cylinder, with the plunger, connecting rod and the outside of the articulated lever separated by the axis of rotation of this. This arrangement allows the individual feeding of each cylinder facilitating later, its possible use in two times with the possibility of self-feeding. The balancing of the engine is achieved by coupling the pistons of each cylinder to a crankshaft journal offset angularly the same number of degrees as these, so all the elements that move in its interior during the rotation of the same maintain a homogenous mass distribution. The self-feeding of the motor consists in that, when the chambers are separated, the air or mixture is sucked directly to the rear of the cylinder, compressed during the retraction of the piston and, subsequently, injected into the combustion chamber of the same or cylinder adjacent. The rotation of the block also favors the dissipation of heat generated during combustion.

Description of the drawings. To complement the description that is being made, and in order to help a better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part of the same, a series of figures, with an illustrative and non-limiting character , both in the proposed directions of rotation and in the dimensions of the different elements, and in which the following has been represented: Figure 1: Shows a plan view of a tangential piston engine balanced two cylinders arranged at 180 s made in accordance with the object of this invention.

Figure 2: Shows a silver view of a balanced tangential piston engine of four cylinders with an arrangement equal to the previous one. The pistons of the opposed cylinders act on equally opposite crankshaft journals and in this case each journal is operated by two articulated levers but also maintain the balance of the masses.

Figure 3: Shows a plan view of a three-cylinder engine, which being an odd number must be balanced as a whole so that being arranged at 120 s each other, its pistons act correlatively on three freighters equally displaced 120 s to maintain mass balance and stability during the turn of the latter.

Figure 4: Shows a plan view of a balanced and self-powered tangential piston engine with two cylinders arranged at 180 s , which injects the oxidizer or mixture into its own cylinder and in expansion phase (4A) with the block turning to the left and the crankshaft to right. Figure (4B) shows the engine with the expansion completed and initiating the admission.

Figure 5: Represents a balanced and self-powered four-cylinder rotary engine with the same characteristics as the previous one and two articulated levers on each journal.

PREFERRED EMBODIMENT OF THE INVENTION As it is possible to observe in the appended figures, there are two preferred embodiments for the balanced rotary engine. The first embodiment shows a balanced rotary engine (figures 1, 2 and 3), while the second embodiment shows a balanced and self-powered rotary engine (figures 4, 5, 6, 7, 8, 9 and 10). In the balanced rotary engine, the pistons (11), (Figures 1, 2, and 3) are coupled by means of their connecting rods (12), and the articulated lever (13), to a journal (14), of the crankshaft ( 15), displaced the same number of degrees as the cylinders (16), thus achieving its alternative linear displacement during the rotation of the assembly (the block with these elements rotates in one direction and the crankshaft in another) being permanently balanced, either by the opposite or as a whole, in the case of an engine with an odd number of cylinders (Fig. 3). This arrangement allows two pistons (11) to couple (Fig. 2) to the same journal (14) of the crankshaft (15) as long as the above is maintained. The crankshaft (15) and the grooved part of the articulated lever (13) are located in a chamber in the central part, separated from the external ones by the axis of rotation (17) of this lever (13), allowing its individual greasing by oil accumulated therein, while the pistons (11), connecting rods (12) and the outer part of the articulated lever (13) can be made by different means; in the case of operating in two stages with oil added to the fuel and in other cycles injected directly into this area, or allowing a controlled passage from the central chamber (by centrifugal force) and subsequently recovering it by means of a planned pump for this purpose. In the embodiment as balanced and self-powered rotary motor, (Figs 4, 5, 6, 7, 8, 9 and 10) the air or mixture is sucked directly to the rear of the cylinder (26), compressed during the retraction of the plunger (21) and subsequently injected into the combustion chamber thereof or the adjacent cylinder (26). The air or mixture (Fig. 4 and 5) is sucked by the plunger (21) during the forward movement through the one-way valve (28) to the rear chamber of the cylinder, compressed during the retraction of this and injected into the combustion chamber through the duct (29) and the valve (210) controlled by a mechanism operated by the connecting shaft (211) of the connecting rod (22) to the articulated lever (23): this shaft is coupled in its inner part a bearing (212) that when moving backwards attacks the profile (213) causing it to turn and by means of the cam (214) that carries coupled on the outside of the axis of rotation, acts on the rod (215 ) that moves the rocker (216) and opens this intake valve by sweeping the gases that are coming out of the nozzle (217) and fills the chamber for a new combustion. In figures 6 and 7, we see the same process, but in this case the comburent or mixture is injected into the chamber of the adjacent cylinder (26), the bearing (212) has been replaced by a blade (221), which acts directly the valve by means of a profile with a rocker attached to its axis. The mechanisms to control the opening of the inlet valve can be replaced by another system, such as those currently used based on gears or pulleys operated directly by the crankshaft. Figure 7 shows the sequence of movements of a balanced and self-powered rotary engine with two cylinders. At a first moment (Figure 7A) the cylinder 6 'is in the compression and admission phase by its rear zone, the cylinder 6 ", which belongs to another body, is in the expansion phase In sequence 7B the cylinder 6' completes compression and 6 "is still in expansion phase. In the sequence 7C the cylinder 6 'is reaching the end of its stroke, the blade acts the profile that opens the intake valve of the cylinder 6 "and the comburent or mixture compressed by the cylinder 6' enters the intake chamber, the The exhaust nozzle is partially open to facilitate the sweep of the gases and the cylinder 6 "starts the compression phase. In the sequence 7D the cylinder 6 'ends the expansion phase and the blade releases the profile, the cylinder 6 "inlet valve closes when the exhaust nozzle is already closed, and this continues with its compression phase. In Figure 8 it can be seen that the plunger (21) is provided with a skirt (218) to prevent the rear chamber of the cylinder from coming into contact with the exhaust nozzle (217) during the forward travel thereof. The fuel inlet is provided through the front axle (219) and this can be injected directly into the combustion chamber for diesel cycles, in the intake duct (29), or to the inlet of the oxidizer by the one-way valve (28) This valve (28) can be rotary, sheet, spring or controlled by a mechanism similar to those described above. Figure 9 shows in detail the design and action of the mechanism that acts on the intake valve for a balanced and self-powered rotary engine that injects the oxidizer or mixture into the adjacent cylinder. The roller (212) has been replaced by the blade (221), fixed to the connecting shaft (21 1) of the connecting rod with the articulated lever, and acts on profile (213), joined by an axle to the rocker arm (216) that open the intake valve. In Figure 9A the vane (221) reaches the profile (213), and moves it upwards, causing the rotation of its axis and of the rocker (216) that is transmitted to the intake valve, opening it. When it reaches the end of the stroke, the wing (221) leaves the profile (213) free and the rocker (216) recovers its position driven by the spring of the valve (210). In Figure 9B, the vane (221) inverts the movement and attacks the profile (213) at its upper part, turning the rocker (216) in its opposite direction and when it is free, the rocker returns to its support position again on the valve (210) by the action of the spring (220). Figure 9C shows the view of the head of the lever articulated with the axis (211) of the articulated lever (23) and the blade (221) while in figure 9D the profile (213) and the beam are seen (216) which operates the valve (210). Once the nature of the present invention has been sufficiently described, as well as a way to carry it out, it only remains to be added that said invention may undergo certain variations in form and materials, as long as said alterations do not substantially change the characteristics claimed. then.
