DESCRIPTION OF THE INVENTION
The invention relates to engine building, in particular to internal combustion engines, and can be used as hydraulic vacuum pneumatic pumps.
Known rotor-piston engine (RPD) F. Wankel (see the magazine "Behind the wheel", 1970, No. 12).
The engine has a piston-rotor with three protrusions, under the influence of a special eccentric, it makes an epicyclic movement. In this case, the protrusions of the rotor contact the inner surface of the stationary stator all the time. Inside the rotor there is a toothed crown that rolls around the shaft six and drives it into a rotational motion together with the shaft.
The drawback of this movement is an undesirable breakthrough of the compressed mixture from one chamber to another and vibrations, which increase due to the forces of inertia that increase with increasing rotational speed of the rotor.
And the rotary engine is known, the author's certificate of the USSR N 1017803, 1983, containing a body with a profiled working surface, end caps, a cylindrical rotor mounted on the shaft and equipped with oscillating pistons in contact with the profiled working surface of the shell and forming supernumerary and piston volumes, gas exchange , Made in the form of inlet and outlet windows and spark plugs.
Analysis of the design of this engine shows the technological complexity of manufacturing its parts, assemblies, the impossibility of sufficiently reliable seals of variable volume chambers.
The proposed engine is devoid of these drawbacks, it is evident from its design and description of the principle of operation.
The task of the proposed technical solution is to create a reliable internal combustion engine that is reliable in operation, simple and technologically efficient.
The technical result is the elimination of the shortcomings of the previous proposed ICE. This technical result is achieved by the fact that the proposed engine consisting of a stationary body with an internal cylindrical surface of intake and exhaust ports, a chamber of a compressed combustible mixture, a valve for transferring from the compression chamber into the chamber of a compressed combustible mixture and an outlet port from the chamber of the compressed fuel mixture into the combustion chamber, Rotor with two protrusions-pistons along the outer surface adjacent to the inner cylindrical surface and the walls of the body, two flaps with parallel lateral planes for uniform fitting of the end part of the flaps to the outer surface of the rotor, made in the profile in the form of an arc, radially to the outer surface of the rotor moving in Housing, in grooves of the same profile, adjacent to the inner walls of the shell and the outer surface of the rotor.
To securely adhere to the outer surface of the rotor in hermetically sealed slots in which the flaps from the chambers move, compressed gas is fed through the channels into the groove on the outer ends of the flaps, and it is possible to press the flaps with springs, as options for creating a mechanical linkage between the rotor movement and the lever flaps, M. Mechanisms.
This creates a reliable sealing of the dampers with the inner walls of the housing, the rotor with the walls of the housing, the design of the rotor is symmetrical, the center of gravity coincides with the axis of rotation of the rotor, which eliminates shock and vibration loads.
The proposed engine is simple in design and technological in manufacturing. The author from "Science and Technology" does not know the above set of existing features that characterize the essence of the claimed invention, which makes it possible to conclude that the invention meets the criterion of "novelty". In the opinion of the authors, the essence of the claimed invention does not follow for a specialist explicitly from the prior art.
The proposed solution makes it possible to create an easy-to-manufacture and reliable internal combustion engine.
The engine design does not create shock and vibration loads, but it allows to create reliable uniform fit between the surfaces of the rotor, the body and the shutters that limit the chambers of variable volume, allows to choose the optimal nonlinear change in the volume of the chambers and their number.
This is a new means of combining the features that distinguish the claimed technical solution from the prototype.
Therefore, we can conclude that it corresponds to the criterion of "inventive level". The set of existing features characterizing the proposed engine can be reused, which is confirmed by the description of the engine operation and therefore meets the criterion of "industrial applicability".
The essence of the invention is illustrated by a drawing, which schematically shows a cross-section of the engine, and a section along the plane AA, which shows the section of the chamber of the compressed mixture, the relief valve and the outlet port into the combustion chamber.

It consists of a fixed body 1, a rotor 2, a shutter 3, a chamber of shutters 4, gas channels to chambers 5, a spring of dampers 6, a chamber of a compressed mixture 7, a bypass valve 8, exhaust ports to a combustion chamber 9, candles or nozzles 10, chambers Variable volume 11, inlet window 12, outlet window 13, rotor shaft 14. The engine is operated as follows. When the shaft 14 is rotated, the rotor 2 is driven with two piston protrusions adjacent to the inner cylindrical surface to the walls of the body 1, moves radially in the body 1 two shutters 3 adjacent to the inner surfaces of the body 1, the outer surface of the rotor 2, and creates chambers of a variable Volume 11. Thus, while rotating clockwise, the volume of the left lower chamber 11 is increased, the inlet of the combustible mixture is introduced through the inlet window 12, this mixture is compressed in the left upper chamber 11 and through the bypass valve 8 fills the chamber with the compressed combustible mixture 7, during the filling of the chamber with compressed fuel Mixture from the compression chamber, the exhaust port 9 into the combustion chamber is closed by the surface of the protrusion-piston of the rotor, the combustible mixture from the chamber of the compressed mixture through the exhaust port 9 opening by the movement of the protrusion-piston enters the right upper chamber 11, ignited by a candle or nozzle 10, On the protrusion-piston of the rotor 2 and rotates the rotor 2, the shaft 14, with the further rotation of the rotor, the exhaust port 13 is opened and the exhausted gases are discharged, then the rotor piston is through the right lower chamber 11, the exhaust port 13 pushes the remaining exhaust gases. The flaps for tight fitting to the outer surface of the rotor are pressed by springs 6, or compressed gas is supplied from the chamber 11 through the gas channels 5 to hermetically closed slots 4 to the outer ends of the flaps. Thus, in the four chambers 11 formed between the two pistons of the rotor 2, the two flaps 3 and the inner surfaces of the body 1. there is successively the injection of the combustible mixture, compression, ignition, expansion of the combustion products, cleaning of the exhaust gases, i.e. All processes occurring in the ICE are being carried out. |
The proposed design allows the engine to be made of materials and technology, which are used in the manufacture of reciprocating engines, as well as from cermets. Without the chamber of the compressed combustible mixture it is possible to use it as vacuum, pneumatic, hydraulic pumps.
