DESCRIPTION OF THE INVENTION
The invention relates to engine building, in particular to internal combustion engines having correction of a displacer in a working cavity.
A rotary piston engine is known, which contains a 3-faceted propellant rotating on the eccentric shaft, moving along the epitrochoid trajectory due to synchronizing gears in it with internal gearing and simultaneously performing the function of the oil pump (see AS 179118) .
A rotary piston machine with an epitrochoid surface for a displacer is known, having a rotor structural element contacting with rollers evenly fixed along the circumference of the housing (see AS No. 1315624, USSR) .
The main disadvantages of rotary piston ICEs with polyhedral rotor-propellant and gear transmission providing movement of faces along the stretched epitrochoid are, in addition to low manufacturability in the process of manufacturing a shell with cavity of an epitrochoid configuration, the absence of a seal between parts of the combustion chamber containing combustion products of a mixture with a higher pressure Gases in the part of the chamber that is remote from the outlet and with less pressure in the part of the combustion chamber adjacent to the outlet. Inevitably, the bypass of gases from the area of increased pressure into the region of reduced and subsequent release into the atmosphere reduces the efficiency of conversion of combustion of fuel into operation and leads to loss of fuel due to premature release of the unused combustion products. At the same time, combustion of the part of the fuel that is let into the atmosphere creates a higher temperature, which increases the negative effect of compaction on the surface of the epitrochoid, which is associated with a decrease in the life of rotary piston ICEs.
An engine is known comprising a housing having an oval cavity for a trihedral extruder and allowing for improved fabricability of the manufacture, but not having a noticeable effect on others, in this case inherent disadvantages not eliminated since the invention of the engine (see AS No. 131592) .
The closest in terms of the technical nature to the claimed solution is the rotary internal combustion engine described in RF patent No. 2032809 and comprising a housing with side covers, a trihedral extruder, a drive mechanism with an eccentric corrector and shaft, a valveless gas exchange system, And outer engagement. However, the known engine has a high speed compared to the piston, which requires the complication and increase of the gearbox of vehicles due to the small gear ratio of the synchronizing mechanism and the need to reduce the speed before the main gear. In addition, in the known solution, the selection of power for the drive of auxiliary aggregates is complicated and the wear of the practically epitrochoid surface of the working cavity and the large displacement velocities of the displacement seal contacting it, operating under conditions of high thermal stress, are increased. This requires for the manufacture of the engine more wear-resistant and expensive materials.
The invention solves the problem of increasing the durability, reducing the cost, increasing the compactness and economy of the engine.
The execution of the engine ensures the receipt of the declared effects due to the placement of heavily loaded structural elements outside the zone of high thermal loading and the reduction of contact stresses of the elements contacting in the cavity of the displacer with the exception of bypassing the unused combustion products and improving the completeness of combustion of the mixture.
The problem is solved due to the fact that in a rotary engine comprising a body with side covers provided with a working chamber therein, a trihedral extruder, a drive mechanism with an eccentric corrector and a shaft, a valveless gas exchange system, internal and external gearing gears, the propellant is suspended on an eccentric corrector via Rotation support, rigidly connected to the traverse and output shaft and placed in an elliptical shaped working chamber, and the rotation supports interact with the elliptical surfaces of the working chambers.
The eccentric corrector through the rotation support can be suspended on the crankshaft with the possibility of the opposite rotation with a ratio of 1: 1.
The propellant can have a rotation relative to the crankshaft with a gear ratio of 1: 3.

FIG. 5-6 - kinematic schemes of the device of the engine
The rotary engine of FIG. 1 consists of a housing with an elliptical surface 2 in which the circumferential walls 3 and the diametral 4 having the channels 5 form a working cavity 6 of the propellant 7 which is mounted on the crankshaft neck 8 by means of an eccentric sleeve 9.
This sleeve is mounted on the neck 8 in a position allowing it to rotate in a direction opposite to the direction of rotation of the crankshaft 10 and has a gear 11 of external engagement. This gear cooperates with the pinion gear 12, the gear 13 of which is driven by a pinion 14 rigidly fixed to the crankshaft 10 and meshing with the intermediate gear 15 (see the diagram in Figure 5), with the expeller 7, the cross member 16 is rigidly connected to the rollers 17, Contacting with the elliptical surface 18 of the working cavity. The other end of the crosspiece 16 is connected via a compensating coupling 19 to the output shaft 20, and the second end of the crankshaft is rotatably mounted in the hole 21. At the end of the shaft 20, a counterweight 22 is provided.
ROTARY ENGINE WORKS AS FOLLOWING
In the FIG. 2 the position of the displacer in the sectors k, l, m, formed by the faces of the displacer and the corresponding section of the ellipse surface 2, known gas-dynamic processes are simultaneously performed: in sector k - ignition and working stroke, in sector l - combustion products and sector blowing, and in sector M - inlet of the fuel mixture and compression of it.
After turning the face of the displacer DB to overlapping the vertex B of the window 23, the volume of the sector m decreases, the mixture is compressed until the bottom of the elliptic surface 2 passes through the vertex B. In this position, the spark plug located in the hole 24 in the compressed mixture is ignited, Pressure, temperature of the mixture with combustion products. The volume of the sector k begins to increase with the further rotation of the displacer, the mixture of combustion products is expanded and the first working stroke of the rotor is before the vertex D is displaced to hole 25, after which it is opened by the last vertex D and the exhausted combustion products leave the atmosphere first due to their pressure, and then Are displaced by the approaching face of the OBD, including from the combustion chambers p, with the complete elimination of the bypass of the unused combustion products. The vertex D at that time opens the window 23 and repeats the operations of the cycle in the described manner. The cycle of engine operation is accordingly repeated by other faces of the displacer. The intermediate positions of the propellant are shown in FIG. 3, pos. I-IV, Fig. 4, pos. V-XII.
The cooling liquid in the channels 5 of the walls 3, 4 reduces the heating of the ellipse surfaces 2, 18, the rollers 17 of the traverse 16 and the gear shift gears, and the thermal tension of the propellant material.
Filling the fully flushed sectors with a new charge of the mixture without mixing it with the residues of the combustion products improves the efficiency of conversion of fuel energy into mechanical work.
The counterweight 22 improves the smoothness of the rotor rotation, as in the known solutions.
In Fig. 6 of the figure, the kinematic scheme of the particular embodiment of the claimed solution is shown with the rotation of the second end of the crankshaft 8, 10 in the housing bearing (not shown).
Unexpected in FIG. The 5 positions of the components of the eccentric-gear compensator are similar to these positions in FIG. 6th
