As a result of the improvements made provided the engine of manufacturing simplicity, increase its durability, increased reliability, mechanical efficiency, rapidity and efficiency.

The problem is solved in that the rotary internal combustion engine comprises a rotor cylinder, twin pistons made cylindrical integrally with the slider and is rigidly connected with the latter, sitting freely on the eccentric, taken on the PTO shaft, which is parallel to the rotor shaft axis and offset relative it an amount equal to the eccentricity of the eccentric, the rotor and the PTO shaft are internal gears with gear ratio 2: 1, of which the large gear with internal teeth is rigidly fixed to the rotor, and a small gear with outer toothing is located on the PTO shaft The rotor is made cylindrical, and in it by the diameter axis formed joints cylinders forming a through hole in which are placed the dual pistons on a radial surface of a cylindrical rotor set free cylindrical rotor ring, at which at the radial surface of the first near the edges of the cylinder are installed sets of radial sealing plates mating at one site with a cylindrical rotor ring, which made the air cooling ducts, the latter are in the slide, a small gear integrally formed with the PTO shaft in a cylindrical rotor-fuel scavenge ports located close to the cylinder end and outlet channels are located much further.

FIG. 1 shows a longitudinal section of the engine

FIG. 2 - view of A-A

A rotary internal combustion engine comprises a housing 1 which encloses a cylindrical rotor 2, wherein the mating cylinders 3 forming the through holes in the cylinders placed cylindrical pistons 4 connected intermediary-slide 5 carried diameter axis formed with them in one piece and freely seated on the eccentric 6, rigidly associated or formed integrally with the PTO shaft 7. In cylindrical rotor 2 is loosely fitted cylindrical ring 8 of the rotor, closes on it opening cylinders 3 and not in contact with the body 1, the closed front end cover 9 and the rear end cover 10 having the central projections 11 and 12 on which rests a cylindrical rotor 2 and through who runs the PTO shaft 7, whose axis O-O ₀₀ shifted relative to the cylindrical axis of the rotor 2 OO on the value of E equal to the eccentricity of the eccentric E ₁ 6 having axis O ₁ -O _1. In dual pistons 4 uses two compression rings 13 and oil scraper ring 14 and on the heads of the pistons are made of the combustion chamber 15, and a cylindrical rotor 2 are toplivoproduvochnye channels 16 and front end cap 17. The nozzle 9 is installed Toplivoproduvochnye set of channels 16 are sealed by sealing plates 18, urged toward the front end cover 9 ribbon spring 19. And on the radial surface of the cylindrical rotor 2, near the cylinder bores 3, installed sets of sealing plate 20 is urged to the cylindrical rotor ring 8 flat springs 21. on the cylindrical rotor 2 fixed rigidly to the synchronizing gear internal teeth 22 and the shaft 7 has a small PTO synchronizing gear 23 and the pinion gear has internal gearing ratio of 2: 1, and it is advisable to perform a gear wheel 23 integrally formed with the power takeoff shaft 7 so as not to reduce the stiffness of the latter. At the ends of the PTO shaft 7 are splines 24 for driving auxiliary units and power circuit. To balance the centrifugal forces of dual pistons 4 and 5 at the ends of the slide PTO shaft fitted counterweights 25 7 closed lid 26. At the front end cover 9 has a cooling blower-box 27, the purge air is shown by arrow 28 and arrow 29 are indicated with a cross waste gases . On the walls of the cylinder 3 has outlet passages 30 at the rear end cover 10 of the body holds the outlet port 31, exhaust ports 30 are sealed cylinder sets seal plate 32. The cooling air is shown by an arrow 33. The slider toe performed air cooling ducts 34 in the cylindrical ring 8 rotor has air cooling channels 35. The central projection 11 and 12, the front 9 and rear 10 end caps are made of cooling oil channels 36, in a cylindrical rotor 2 has oil cooling ducts 37. at the ends of the cylindrical rotor 2 there are inlet air cooling recess 38 and outlet recess air-cooled 39.

A rotary internal combustion engine operates as follows. When you rotate the large timing gear 22 of the rotor 2 and the small timing gears 23 PTO 7 (ratio of the diameter of the pitch circle of the gear is equal to 2:1), the latter is rotated about its axis O-O ₀₀ twice as fast as the cylindrical rotor 2, and with them with the same angular rate it from ₁ rotates together with the cam slider 6 and 5 double cylinder 3 and simultaneously to rotate the eccentric last 6 around its axis O ₁ O ₁ C with an angular velocity _2, together with a cylindrical rotor 2, TE twice slower. As a result, the cylindrical piston 4 with the slider 5 make absolute planetary motion with respect to the axis O-O ₀₀ power take-off shaft 7, but with respect to the cylinders 3, they perform the reciprocating motion.

FIG. 2 - intermediate cylinders and pistons is shown in chain-dotted lines by turning on the initial position of the center O ₁ of the eccentric 6 180 ^o, where he reflected with a prime, ie, pregnant Coinciding with the center 0 of the cylindrical rotor 2 which is turned through 90 ^o, and the cylinders have taken horizontal position and a position of the cylinders and pistons corresponds to the critical point, the output of which is done by synchronizing gear internal toothing 22 and 23, but when running in a cylindrical rotor 2 has cylinders 90 ^o to available. The conclusion of the said provision will be due to the efforts of creating the other pistons in the cylinder wall, enclosing them, but for the operation of the engine with the rapid change of regime will arise large alternating loads of acceleration on the cylinder wall, and it will cause more wear and reduce engine durability. To avoid this, apply timing gears. Cylinders 3 are formed only on one diametrical axis of the cylindrical rotor 2 to enable simplification of engine operation. Check the planetary movement of the pistons has been made on the layout in the metal and flawless graphically confirmed. FIG. 2 that three cylinders are fully upright and the upper compression piston 4 is completed. FIG. 1 shows that at the time of combustion chamber 15 is coincided with-purge fuel channel 16 through which it injector 17, fuel injection is performed, and after the combustion of the formed gases will push the piston 4 and the last transmit this force to the cam 6 and will cause its rotation together with PTO 7. FIG. 1 and 2 show that coincided with the blower, a cooling box 27 and through them at this time in the lower cylinder 3 is supplied purge air 28, which displaces the exhaust gases 29 in the outlet channel 30 in the lower cylinder 3 is completed full expansion of gases and toplivoproduvochny channel 16 and further - the outlet port 31 in the rear end cap 10. Since there is co-current purge cylinders 3 and heavier cold air purge dropped by centrifugal force of the rotor to the edge of the cylinder 2, it provides good cooling of the lower cylinder 3 and its filling quality purge air 28. Upon further rotation of the cylindrical rotor 2, the gas distribution channels of the cylinder separated and begin compression of air and when the cylinder 3 takes the top position, as in the previous FIG. 2, the combustion chamber 15 of the piston 4, it will be injected and the fuel injector 17 after the combustion gases through the piston 4 will create a pressure on the cam 6 and cause it to rotate together with the PTO shaft 7.

Subsequently, all the processes are repeated in the described sequence. After the cylinder purge completion three unused purge air 28 becomes cooling air 33 which passes through the blower, a cooling box 27, the front end member into the receiving recess cooling air 38 one end of the cylindrical rotor 2 and passes through the space between the double piston 4 and through the air cooling ducts 34 slide 5 and the cooling air channels 35 of the ring 8 of the cylindrical rotor, cooling the latter and the pistons 4, enters the diverting cooling channels 39 and exits the outlet port 31 in the rear end cover 10. cooling cylindrical rotor 2 produced oil during its passage through the cooling oil passages 36 projections 11 and 12, front and rear end covers 9 and 10. a cylindrical rotor 2 changes its location in the body 1 and it prevents local overheating it.

A rotary internal combustion engine has a good technical and economic performance. Its cylinders, pistons and seals (formed in the reciprocating engine) cylindrical and therefore provides the same ease of manufacturing and processing, and reached the same effectiveness of compaction, and the appearance of an additional seal between the radial surface of a cylindrical rotor and a cylindrical rotor rings will not affect appreciably on the deterioration of the seal, as the seal kit between the cylinder near the edges of the contact pads on and he can run multi-row, and the mechanical seal loss is almost no effect, as the mating parts at the uniform operation of the engine rotate together with the assumption. The engine is provided with high quality and good scavenging of cooling and cooled in a cylindrical rotor, rotor cylindrical pistons and rings. It order to reduce the force interaction with the cylinder piston and the slider is synchronized rotation of the cylindrical rotor and a shaft through the PTO gear with internal engagement. The engine reaches the desired compression ratio and created a compact combustion chamber. It provided a planetary movement of the masses. The engine makes one combustion stroke when the PTO shaft is rotated by one turn, and his work is equivalent to the single-cylinder engine Wankel. This engine has a simple structure and can achieve a high specific speed and compactness. It has a high mechanical efficiency and has excellent durability and efficiency.
