Abstract

The invention allows to simplify the design of the engine and increase its reliability. For this purpose, in a rotary internal combustion engine with a profiled working chamber and a rotor, in the slots of which hollow separator vanes are installed, the cavity of which forms a high pressure chamber and is connected to the inlet and outlet openings with the working chamber, the outlet opening is made with the possibility of its blocking with the edge of the rotor. The inlet is fitted with a check valve. When the engine is running and the rotor is rotated, the fuel-air mixture is compressed in the high pressure chamber and transferred to the combustion chamber, where it ignites and burns, and the resulting differential pressure is triggered, driving the rotor to rotation and generating useful mechanical power. 5 il.

(57) The invention allows to simplify the design of the engine and increase its reliability. For this, in a rotary internal combustion engine with a profiled working chamber and a rotor,

in the slots of which hollow separation blades are installed, the cavity of which forms a high pressure chamber and is connected with inlet and outlet openings with a working chamber, the outlet opening is made with the possibility of its blocking with the edge of the rotor. The inlet is fitted with a check valve. When the engine is running and the rotor rotates, the fuel-air mixture is compressed in the high pressure chamber and transferred to the combustion chamber, where it ignites and burns, and the resulting differential pressure is triggered, driving the rotor to rotation and producing useful mechanical power. 5 il.

FIELD OF THE INVENTION The invention relates to engine building, in particular, to rotary internal combustion engines.

The purpose of the invention is to simplify the design and increase its reliability,

Figure 1 shows the engine, a cross-section, figure 2 - the same, a longitudinal section; FIG. 3 is a partial sectional view of the engine along a hollow blade and a high pressure chamber with the valve open; 4 is the same with the valve closed; in FIG. 5, an embodiment of an engine with a hollow blade and a spark plug in one piece.

The internal combustion engine contains a fixed housing 1 with a shaped working chamber 2, in which the output shaft 3 is installed

cylindrical rotor 4. In the radial grooves 5 of the rotor 4, hollow vanes 6 and 7 are placed, the internal cavity of which forms a high pressure chamber 8 connected by an inlet 9 with a check valve 10 located in the forward wall in the direction of rotation of the rotor 4 suction and overlapped outlet 12 in the rear wall in the direction of rotation with the cavity of the combustion chamber 13 for compressing the mixture in the high pressure chamber 8 and supplying the compressed mixture to the combustion chamber 13, in the combustion chamber 13 A spark plug 14 is ignited to ignite the compressed air-fuel mixture. The outlet 12 of the camera 8 vysp

Whose pressure is made with the possibility of its blocking the edge of the rotor 4.

In order to carry out gas exchange, an inlet 15 and an outlet 16 windows connected to the respective manifolds (not shown) are provided in the engine casing.

During engine operation and the rotor 4 rotates clockwise into the suction cavity 11 located behind the hollow blade 6 (see Fig. 1), the fuel-air mixture enters through the inlet port 15. Further rotor 4 rotates the fuel-air mixture located in the suction cavity 11, begins to be compressed by the blade 7 and through the inlet 9 and the check valve 10 to enter the high-pressure chamber 8 (Fig. 3). At that moment, when the blade 7 passes the protrusion of the shaped chamber 2, the mixture from the high pressure chamber 8 is compressed through the outlet 12 of the blade enters the zone of the combustion chamber 13 and ignites by the spark plug 14. The products of combustion of the fuel-air mixture act on the back of the blade wall in the direction of rotation of the rotor 4, drive the rotor 4 into rotation and the existing pressure difference is triggered, after which the exhaust gases are discharged through the exhaust port 16 to the atmosphere. In the following, the described thermodynamic process is repeated.

Fig. 5 shows an embodiment of the engine with the arrangement of blades and spark plug in one piece, with the compression and expansion cavities having different volumes due to the different depths of the grooves of the profiled working chamber.

Making the outlet of the high-pressure chamber blocked by the edge of the rotor simplifies the design of the engine and increases its reliability.
