The invention relates to the field of mechanical engineering and, in particular, to engine. Known rotary external combustion engine patent [of the Russian Federation No. 2208176]. In this engine, all processes occur in the same partition, separated by plates. In the cold gas in the part b is heated from the neighbouring parts, through the separating plate and the motor housing. That reduces the efficiency of the engine. Known RF patent №2258824. This engine also hot and cold chambers are located in the same housing. They are separated by a stator. Therefore, the hot gas will be cooled and the cold to warm up through the common wall of the casing and the rotor. That will also reduce the efficiency of the engine. Known description rotary external combustion engine in the journal "Science and life" No. 3 in 2007, This engine is used as a prototype. The main idea of this solution is that on a common shaft with two working cylinders of different lengths with eccentric rotors and spring-loaded separating plates. Cavity discharge (semi - compression) of the small cylinder is connected with the cavity of the expansion of the large cylinder through the slots in the separator plate, pipeline, heat exchanger-regenerator and the heater, and the cavity of the expansion of the small cylinder - cavity injection of the large cylinder through the regenerator and refrigerator. The engine runs after the relevant way. In each moment of the small cylinder in the branch high pressure arrives a certain volume of gas. To fill the cavity of the injection of the large cylinder while maintaining the pressure, the gas is heated in the regenerator and the heater; its volume increases and the pressure remains constant. Same, but with opposite sign" occurs in the branches of low pressure. Due to the difference in surface area of the rotor occurs, the resulting force F=Δp(S6-Sm), where Δ the difference between the pressures in the branches high and low pressures; S6- large working area of the rotor; Sm- working area of the small rotor. This force rotates the shaft with the rotors, and the working fluid is continuously circulated sequentially through the entire system. Useful working volume of the engine is equal to the difference of the volumes of the two cylinders. This engine has no valve in the branch high pressure, which does not allow to increase the pressure of the cold gas before it is fed into the regenerator and the heater. The absence valve allows part of the hot gas to flow back into the short section of the rotor. All this reduces the efficiency of the engine. The purpose of the claimed solution is to eliminate these disadvantages by the use of different designs of blades and engine. The technical result is to improve the process of lubrication of the engine, except the falling of the burnt gases in the working mixture, increase efficiency. This goal and the result is achieved due to the fact that the rotary external combustion engine, consisting of rotor blades, at least two housings, inlet, intake box, combustion chamber, intake valves, combustion chambers, spark plugs, exhaust valve, outlet box, outlet, sealing elements, characterized in that it consists of two sections: hot and cold, the rotors of which is rigidly mounted on the same shaft, the rotor hot section is longer than the rotor of the cold section, and the working area of the blades and the volume of the cavity more hot section; cavity hot and cold sections are connected by two pipes, one of which passes through the cavity cooling, the other through the cavity of the heat, and both intersect the cavity regeneration, on the path from which the cold section of the installed valve. Brief description of drawings Figure 1 shows the design of the engine, where 1 - rotor, 2 - blade, 3 - body, 4 - partition between the working and control cavities, 5 - managing the cavity, 6 - working cavity 7 - seal on the blade. In figure 2, 3, 4, 5 - principle of operation of the engine, where 8 - fridge, 9 - regenerator, 10 - heater, 11 - valve, 12 - input window of the cold section 13 - output window of the cold section 14 - input box, hot section, 15 - output window the hot section, 16 is a shoulder in the hot section, 17 - shoulder in the cold section. The external combustion engine consists of two sections - hot (B) and cold (And). Their rotors are rigidly mounted on the same shaft. For better demonstration of the principle of operation of the engine section shown on the drawings separately. The hot rotor section is longer than the rotor of the cold section. Therefore, the working area of the blades (16) and the volume of the cavity more hot section. Cavity hot (B) and cold (A) sections are interconnected, as shown in figure 2. Since the processes in the cavities similar, the drawing shows only a pair of cavities. When driving the gas it passes through the regenerator (9), the heater (10), refrigerator (8), valve (11). The engine works as follows. The blade (17) is located in front of the entrance hole (12). Valve (11) is closed. The gas from the hot section, passing through the regenerator (9) and a refrigerator (8) in the cold section, cooled and reduced in volume. The pressure in the hot section is reduced. Blade (16) is not reached the entrance window (14) (position 3). Upon further rotation of the blade (17) compresses the gas in the cold section. And simultaneously sucks the cooled gas from the hot section. When a certain pressure valve (11) opens. At this time, the blade (16) in the hot section passes the inlet (14). Passing through the regenerator (9) and the heater (10), the AZ is heated, increases its volume and pressure on the blade (16)performs the work. At the same time the blade (16) is beginning to replace the hot gas from the previous cycle. This gas passes through the regenerator (9), gives off heat to the gas, which at this time comes from cold to hot section. Then further cooled in the refrigerator (8), reducing its volume, and flows into the cold section (position 4). Upon further rotation of the blade (17) replaces all of the gas from the cold section, which expands, doing work in the hot section. When the blade (17) cold section of the outlet (13) of the valve (11) is closed. The gas from the cold section does not come in hot. But the gas is heated and expands in the hot section, continues to put pressure on the blade, making the job (position 5). After passing the blade (16) of the outlet hot section (15) hot gas starts through the regenerator (9) and a refrigerator (8) to enter into the cold section. Being cooled, it reduces its volume. The pressure in the hot cavity begins to decline. Valve (11) is closed. For a while, until the second end of the blade (17) reaches the inlet of the cold section (12), the pressure in the hot and cold sections will be equal (position 6). When the second end of the blade (17) reaches the inlet (12) cold section, the process is repeated. Processes in other pairs of cavities similar. is that for one revolution of the shaft will occur six cycles. Moreover, at any point in time, at least one cavity will always be a work cycle. The number of cavities in the partition may be different, but definitely odd. The principle of operation of the blades is as follows. At some point the distance between the opposite walls is equal to the length of the blade. The blade is fully extended and fixed relative to the rotor during rotation. When the rotor blade interact with the body in the control cavity (5). When the blade moves relative to the rotor (1) in the radial direction. Upon further rotation of the vane under the influence of the casing wall begins to vdvinut'sâ in the rotor, as on the opposite wall begins cavity. When the blade fully retracts into the rotor, it is fixed with regard to him. So cyclically moving relative to the rotor, the blade creates a region of variable volume cavities. As part of the blades are on opposite sides of the axis of rotation, the blade will act centrifugal force only part of the blade protruding from the rotor. Blades can also be more than one. Hot gases will expand to a greater extent, therefore, the temperature and pressure of exhaust gases before release into the atmosphere will be less, which will increase efficiency. The burnt gases will not get into the working mixture, since the cavity is compressed the I and separated combustion. Rotary external combustion engine, consisting of rotor blades, at least two housings, sealing elements, consisting of two sections: hot and cold, the rotors of which is rigidly mounted on the same shaft, the rotor hot section is longer than the rotor of the cold section, and the working area of the blades and the volume of the cavity more hot section; contains the input window of the cold section, the output window of the cold section, input box, hot section, the output window hot section; oral hot and cold sections are connected by two pipes, one of which passes through the cavity cooling other through the cavity of the heat, and both intersect the cavity regeneration, on the path from which the cold section of the installed valve, characterized in that the portions of the blades are on opposite sides of the axis of rotation, and each vane is fully extended and fixed relative to the rotor during rotation when the distance between the opposite walls is equal to the length of the blade.
