Description

The invention relates to the field of mechanical engineering and can be used in transport engine manufacturing to solve the problem of reducing the specific gravity, dimensions and specific fuel consumption of power plants.

Known rotary internal combustion engine containing a housing with a cylindrical bore, and an eccentrically mounted rotor with diametrically profiled grooves and placed in them separation plates having the ability to radially move in the grooves of the rotor and the formation in the housing of the working chambers, and gas exchange windows made on opposite end caps housing in the area of the largest volume of working chambers (DE, application 4117936, CL. F01C 1/39, 1992).

The disadvantage of this engine is the loss of friction of the plates on the housing and the rotor, large leaks of the working medium along the ridges of the plates due to their linear contact with the housing, the large specific gravity and radial dimensions dictated by the need to limit the flight of the plates from the rotor grooves according to jamming conditions, the large mass and dimensions of the cooling system due to the need to utilize the heat released as a result of high mechanical losses.

The closest in technical essence and the achieved effect is a rotor machine containing a housing with channels for supplying and discharging the working medium, a stator ring coaxially mounted in the housing, a rotor eccentrically mounted in the housing, dividing plates having the possibility of forming working chambers in the stator ring, while the housing made of sections, the stator ring is fixed in the form of a sleeve, the rotor contains holes for installing hollow fingers with slots into which are inserted at one end of the plate with ins at the opposite end for installation independently at the shaft disposed coaxially with the axis of the stator ring (see. US 2,001,011 A, 14.05.1935, F04C 2/352).

The disadvantages of the prototype are the high friction losses of the plates on the stator ring and leakage of the working environment.

The objective of the invention is to increase the efficiency of a rotary machine.

The technical effect of the proposed solution is to reduce the forces acting in the kinematic mechanism, compact arrangement of engine systems and assemblies, which will ensure a decrease in the specific gravity and dimensions of the engine and a decrease in specific fuel consumption.

The technical result is achieved in that the rotary machine comprises a housing with channels for supplying and discharging the working medium, a stator ring coaxially mounted in the housing, a rotor eccentrically mounted in the housing, dividing plates having the possibility of forming working chambers in the stator ring, while the housing is made of sections, the stator ring is made stationary in the form of a sleeve, and holes are made in the rotor for installing hollow fingers with slots, into which are inserted one end of the plate with eyes on the opposite side nets for installation independently from each other on a shaft located coaxial with the axis of the stator ring, the housing made of seven sections, with holes for the cooling system connected by studs, and the rotor made of two sections, the stator ring is installed in the fourth section of the housing, and the plates on the end surfaces of the plates contain rectangular seals, and on the upper and lower surfaces contain spring-loaded seals.

Sealing elements are installed in the finger slots.

The spring-loaded seals are connected to the plate in the form of a protrusion-groove.

In this design, four blades in the form of blades rotate along their path, regardless of the position of the rotor, since they are mounted on a shaft located eccentrically to the rotor shaft. During rotation, the angle between the plates changes, changing the volume of the working chambers in the stator ring. The proposed design eliminates jamming of the plates, the location of the plates on an independent shaft allows to reduce the height of the plates and the diameter of the rotor, and due to this, the diametrical size of the entire kinematic mechanism. And the installation of the shaft in the bearings on both its sides eliminates jamming and displacement.

Figure 1 - shows a rotary machine, a cross section.

Figure 2 is a section along BB.

Figure 3 is a General view of the plate with seals.

The rotary machine contains a housing 1, consisting of seven sections ("a", "b", "c", "g", "d", "g", "h"), the stator ring 2 installed in it in the form of a sleeve, eccentrically placed in ring 2 rotor 3, hollow fingers 4 with slots, plates 5 with seals, shaft 6 for installing plates, hole 7 for installing a spark plug, channel 8 for discharging an exhaust gas mixture, channel 9 for drawing in a combustible mixture, holes 10 for bolts , cooling holes 11, gear 12 for rotor power take-off, radial bearings 13 of the rotor, turbine 14 for pressurization of the combustible mixture, side wings pulleys 15 of the housing, carburetor 16, bearings 17 of the plate shaft, mechanical end seals 18, spring-loaded seals 19.

I chamber - the beginning of the working course

II chamber - working stroke

III chamber - suction

IV camera - compression

From the power take-off shaft through a gear connection, the rotation is transmitted to the rotor, the engine starts.

In chamber I, ignition occurs from a candle, which is the beginning of a working stroke. In chamber II, the continuation of the working stroke, when the plate is rotated 180 °, the exhaust window opens with a mechanical seal 18 of the plate. Through channel 9, the combustible mixture enters chamber III; in chamber IV, the working mixture is compressed. The cycle repeats.

The proposed design of a rotary machine can be used as a compressor, pump.

This design of the rotary machine can significantly increase the efficiency by reducing friction losses, reducing specific fuel consumption.
