Description

The utility model relates to engine building, namely to internal combustion engines with rotating rotors.

Known rotary internal combustion engine (US patent US 2003047158), consisting of a housing offset from the axis of rotation of the rotor. The blades are pivotally attached to the rotor and create separate chambers in the engine. Each of the cameras has the ability to work on the Otto cycle. Each chamber has spark plugs and intake and exhaust valves that allow you to suck in a fresh mixture and remove exhaust gases.

The disadvantage of the engine is low reliability due to the fact that the swivel mounting of the blades are in the combustion zone of the fuel.

Known rotary vane internal combustion engine (RF patent No. 2413853). The engine consists of a housing with a cavity in which a rotor with rotor blades and a copier are mounted, which is installed in the housing with an eccentricity to the rotor axis. During engine operation, the rotor blades rotate with the rotor and at the same time make radial movements, rolling with rollers along the ring tracks of the copier. The combustion of fuel occurs in the working chambers, the pressure difference in the working chambers causes the rotor to rotate.

The disadvantage of this engine is low reliability, since the interaction of the blades with the rotor occurs near the combustion zone of the fuel, which will lead to the failure of the blades.

For the prototype adopted rotary vane internal combustion engine according to the patent of the Russian Federation No. 2589882. The engine consists of a housing, inside the housing there is a rotor with grooves in which the blades are placed. The engine has a pulsating fuel injection system, the compression zone of the combustible mixture, the ignition of the combustible mixture is produced from a candle located in the compression cavity, and then follows the expansion zone and the exhaust zone. The advantage of the engine is speed. The engine in one revolution of the rotor makes four working strokes. No well-known engine allows you to get such a high intensity of work

The disadvantage of this engine is the low reliability of the engine, since the force interaction between the blades and the rotor occurs in the fuel combustion zone. This will lead to a quick engine failure.

The objective of this utility model is to create an engine with high reliability and high speed, providing at least two working strokes per revolution of the rotor.

The problem is solved in that the high-speed engine consists of a housing with a cavity in which a rotor is placed, equipped with radial slots, with plates placed in them, which form working chambers of variable volume in communication with the combustion chamber. The engine also contains a motor part and compressor parts. The size of the motor part in the axial direction exceeds the total size of the compressor parts, which are divided into two parts and placed at the edges of the motor part. The plates in the engine are made as a whole, in addition, a copier is placed in the engine housing, which is made in the form of a closed ring smooth wave line without break points and return points. The number of peaks and troughs of the wave line on the copier has no restrictions upward. It is envisaged that the copier consists of two parts, internal and external, between which the plates are placed. In addition, the outer part of the copier is the inner surface of the housing, located outside the flow parts of both the engine and the compressor in the axial direction. Moreover, the inner part of the copier is attached to the side wall of the engine housing and made a reduced copy of the outer part in the circumferential direction. Also, shoes are pivotally attached to the ends of each plate in the radial direction with the possibility of moving in the circumferential direction, both on the outer and inner parts of the copier, in addition, with the possibility of oscillating movements in the circumferential direction. Moreover, it is provided that for each pin attached to the plate and placed with its free end in closed recesses made in the side walls, a shoe is pivotally connected with the possibility of moving in the circumferential direction also with the possibility of oscillating movements in the circumferential direction. It is also provided that closed rings are placed on the inner surface of each side wall of the engine. In addition, two pins are attached to each plate with a gap in the radial direction, and shoes are pivotally mounted on the pins with the possibility of oscillating movements in the circumferential direction. In addition, in the gap between the shoes placed the free end of the ring with the ability to move the shoes in the circumferential direction.

The high speed engine of FIG. 1-3 consists of a combustion chamber 1, and provides for the installation on the engine of one or several combustion chambers. The engine also consists of a motor part 2, an inlet 3 in the housing of the motor part, which is connected to the combustion chamber. The working fluid from the combustion chamber enters the engine part into the inlet window in the direction of arrow A1 into the working chambers 4, which are formed by the plates 5. The working chambers for the engine and compressor have the same designation. In the working chambers of the engine, the working fluid expands, under the influence of the pressure difference on the plates, the rotor 6 rotates, along arrow C. The plates in the engine are made as a single unit and the force effect of the plates on the rotor is carried out in the guiding parts 7 of this engine. The guide parts are placed along the edges of the engine in the axial direction near the side walls of the housing, in the zone of low temperatures. In the guide part, guide elements 8 are attached to the rotor, in which the plates are placed, forcing the rotor to rotate. The guide elements also allow the plates to move in the radial direction. On the inner side of both side walls of the engine casing, recesses 9 are made in the form of a closed annular smooth wave line without break points and return points. A pin 10 is attached to each plate in the guide parts, which is placed with its free end in the undercut, with possible movement in the circumferential direction. The recesses in the side walls act as a copier and force the plates to move back and forth as the rotor rotates. The axis passing through the centers of the copiers coincides with the axial line of the shaft. Compressor parts 11 contain exhaust windows 12 through which compressed air is directed into the combustion chamber (arrow B). Fresh air enters the inlet windows 13 of the compressor parts, into the working chambers, where it is compressed (arrow A). The compressor parts are placed along the edges of the motor part in the axial direction. Exhaust gases from the engine part are removed along arrow B1 to the exhaust windows 14. The sealing elements 15 are located in the engine part and in the compressor parts to prevent leaks. If necessary, guide elements are also located in the engine part and in the compressor parts. The dashed line 16 corresponds to the shape of the copier.

In FIG. Figures 4-9 show a high-speed engine in which the copier is made of two wave peaks without inflection points between them, and the copier in this case has an oval shape. A small number of waves simplifies the engine and makes it more reliable, otherwise there is no fundamental difference in the arrangement of engines. (Designations in all figures are retained.) In FIG. 4 shows an engine with two combustion chambers. The engine contains a receiver 17, where compressed air is supplied from the compressor part, then the air is directed to a regenerator 18 located in the exhaust pipe 19. In FIG. 5 shows the engine part, which coincides in shape with the compressor part and has one combustion chamber. In FIG. 6 shows the compressor part of the engine, which is the same for each of these engines. In the air compression section of the compressor and in the expansion section of the working fluid in the engine, the inner surface of the casing and the copier in the circumferential direction are similar, in other sections this is not necessary. In FIG. 7-9 show the guide parts, which are placed along the edges of the engine outside the engine part and outside the compressor parts. In FIG. 7 shows a guide part, which consists of an external and an internal part. The copier in the guide part consists of two parts, the inner and outer, the outer part of the copier is the inner surface 20 of the housing, located outside the flow parts of the engine and compressor in the axial direction. The inner part 21 of the copier is attached to the side wall of the engine housing and made a reduced copy of the outer part in the circumferential direction. Plates are placed between the outer and inner parts. Shoe 23 is attached to the ends of the plates in a radial direction on hinges 22, and shoes of a smaller size are made for the inside of the copier than to the outside. Guide elements are attached to the rotor, in which the plates are placed, forcing the rotor to rotate. Also, the guiding elements direct the movement of the plates in the radial direction. The shoes pivotally mounted on the plates force the plates to move back and forth as the rotor rotates. In FIG. 8 a copier is made in the form of a recess 24 in the side walls of the engine casing. The axis passing through the centers of the copiers coincides with the axial line of the shaft. On the pin, a shoe is pivotally mounted on the plate, which is made with the ability to move along the undercut in the circumferential direction. In FIG. 9, a copier is made in the form of a closed ring 25 placed on the inner surface of each side wall of the engine. In this case, two pins with a radial clearance between them are placed on the plate, shoes are pivotally mounted on each pin. A closed ring is placed in the space between the shoes, with the possibility of free movement of the shoes along the ring in the circumferential direction, both on the outer and inner parts of the ring.

When operating a high-speed engine in fig. 1-3, the action of the plates 5 on the rotor 6 is carried out in the guide part 7, where guide elements 8 are attached to the rotor, in which the plates are placed, forcing the rotor to rotate. Under the influence of the working fluid on the plates, the rotor rotates, which is indicated by arrow C. When the rotor rotates, the pin 10 moves along the recess 9 and since the recesses in the side walls are made in the form of a wave line, the plates are also moved back and forth in the guide elements. In this case, the guiding elements direct the movement of the plates in the radial direction. Compressed air enters the combustion chamber from the compressor parts 11 through the exhaust ports 12 (arrow B). Fresh air enters the inlet windows 13 (arrow A), into the working chambers of the compressor 4. The exhaust gases are removed along arrow B1 to the exhaust windows 14 in the engine part. Sealing elements 15 in the engine part and in the compressor parts prevent leakage. The dashed line 16 corresponds to the shape of the copier.

The engine during operation for one revolution of the rotor makes six working strokes, which is more than a prototype.

The operation of FIG. 4-9 of the engine, where the copier is made in the form of an oval, is carried out similarly. In this case, the engine performs two duty cycles per revolution of the rotor. In FIG. 4 shows an engine with two combustion chambers 1. Combustion in the combustion chambers during engine operation is continuous. To reduce air pulsations, the engine contains a receiver 17, where compressed air is supplied from the compressor part 11, then the air is sent to a regenerator 18 located in the exhaust pipe 19. The working fluid is expanded in several working chambers 4, this reduces the load on the plates 5 and increases reliability engine. Since the dimensions of the motor part in the axial direction exceed the total size of the compressor parts, the expansion of the working fluid occurs to a low value close to atmospheric pressure, that is, the engine operates according to the Brighton cycle. In FIG. 5 shows the engine part 2, which coincides in shape with the compressor part 11 and contains one combustion chamber 1. FIG. 6 shows the compressor part 11 of the engine, which is the same for each of these engines. In FIG. 7-9 presents the guide parts, which differ copiers. In FIG. 7 shows the guide part 7 of the engine, in which the copier consists of an outer 20 and an inner 21 part. When the engine is running, the shoes 23 slide in the circumferential direction along the surfaces of the copier, forcing the plates 5 to move reciprocally, and also the plates move in the circumferential direction and radially, to which they are forced by the guiding elements 8 mounted on the rotor 6. In FIG. 8, a copier is made in which in the recess 24 on the pin, it is pivotally mounted on the shoe plate, which during operation moves along the recess in the circumferential direction. The guiding elements 8 attached to the rotor force the plates to move in the circumferential and radial directions. In FIG. 9, the copier is made in the form of a closed ring 25. The shoes 23 cover the ring from two sides and, when operating, slide along it in the circumferential direction. Hinges 22 in all copiers allow the shoes to oscillate in the circumferential direction.

With six waves placed on the copier, there are six working strokes for one revolution of the rotor, which is more than that of the prototype. Moreover, for such engines this is not the limit, but a large number of waves are easier to use on large engines. The force interaction between the rotor and the copier is carried out in the low temperature zone, the shoes increase the area of contact with the copier, which increases the reliability of the engine in comparison with the prototype.
