Abstract

FIELD: engine building.

SUBSTANCE: invention relates to rotary-vane internal combustion engines. Essence of invention consists in that engine comprises chamber, in base of which three arcs of equidistant circles connected to each other by curve, built of points, which have equal distance to inner surfaces of arcs along straight lines passing through central point, from which equidistant circles are located. Said point is the center of the figure base with invariable distance between two points located in one plane, lying on the surface of the chamber and connected by a straight line passing through the central point. According to the invention, the engine is made of sections with shafts, in which blades are made with possibility to provide passage of shafts located one in the other and rotating in different directions. Engine with two independent rotation shafts having common rotation axis enlarges the range of possible application of this type of engine.

EFFECT: technical result is reduction of energy losses due to reduction of number of friction pairs, reduction of number of assembly units and transfer of energy via blades directly to rotor.

State of the art.

The main unit on cars, tractors and other equipment is the internal combustion engine (ICE). The main feature of which is the ignition of the fuel directly inside its working chamber; in the process of operation, chemical and thermal energy from the combustion of the fuel is converted into mechanical work.

The principle of operation of the internal combustion engine is based on the physical effect of thermal expansion of gases, which is formed during the combustion of the fuel-air mixture under pressure inside the engine cylinders. ICEs are subdivided into piston and rotary-piston

In piston internal combustion engines, the working chamber is located inside the cylinders, and thermal energy is converted into mechanical work by means of a crank mechanism that transfers energy to the crankshaft.

In a rotary-piston internal combustion engine, thermal energy is converted into mechanical work through the rotation of the working gases of a rotor of a special shape and profile. The rotor moves along a "planetary trajectory" inside the working chamber, having the shape of "eight", and performs the functions of both a piston and a gas distribution mechanism and a crankshaft.

The presented rotor-blade engine can be considered an analogue of the VANKEL rotary-piston engine. (Rotary piston engine "Great Soviet Encyclopedia", Ivan Pyatov "RPD from the inside and outside")

WANKEL engine design:

The rotor mounted on the shaft is rigidly connected to a gear wheel, which meshes with a stationary gear - a stator, the difference in the presented rotary vane engine is that the rotor is directly mounted on the shaft and has a common axis of rotation with the shaft. The transmission of torque occurs directly from the rotor to the shaft. The rotor diameter in the WANKEL engine is much larger than the stator diameter, despite this the rotor with a gear wheel rolls around the gear. Each of the vertices of the triangular rotor moves along the inner epitrochoidal surface of the cylinder and cuts off the variable volumes of the chambers in the cylinder using three radial seals,

The difference in the presented version of the engine is that the blades moving independently of each other, through the rotor body, cut off the variable volumes of the chambers in the cylinder.

The shape of the cylinder chamber in the VANKEL engine is an epitrochoid, and in the presented version, the shape of the cylinder chamber at the base has a three-lobed figure. The difference is that in one revolution of the rotor, the eccentric shaft makes one revolution.

Disclosure of the rotary vane type engine.

The rotor is part 1, cylindrical in shape, located on the shaft - part 2, and rotates directly with the shaft, inside the working chamber of the cylinder - part 3. The rotor itself does not come into direct contact with the cylinder chamber. The chamber of the cylinder at the base is a three-petal figure. (shown in Figs. 2, 3, 4, 5, 6, 9)

Through the rotor body, along the guides, two cross-shaped blades move - part 4, the blades move among themselves independently. Energy is transferred through the blades to the rotor. The movement of the blades is limited by the inner surface of the cylinder chamber. (shown in Figs. 2, 3, 5, 6, 7, 9)

The blades are plates, with installed at their ends, packs of sealing plates - detail 5. (shown in Fig. 2, 3, 6)

In those places of the rotor, where the blades move through the rotor body, it is also provided for the installation of packs of sealing plates - part 5. (Fig. 2, 6)

The space between the inner surface of the cylinder chamber, between the blades and the outer surface of the rotor is a cylinder cavity - part 6 (Fig. 2), respectively, we have two cylinder cavities. The principle of operation is shown in Fig. 8

When the engine is running, when both cylinder cavities are involved, only when one cylinder cavity is filled with air or a mixture of air and gasoline, then the mixture is compressed and ignited in the second cavity.

This is due to the special shape of the camera - at the base of which there is a three-petal figure, if we look at it in more detail, it is a geometric figure of a cylinder, at the base of which there are three arcs of equidistant circles connected by a curve built from points that have the same distance to the inner surface of the arcs along straight lines passing through the central point from which the circles are equidistant (Fig. 1). This point is the center of the base of the shape. The shape outline is: arc, curve of points, arc, curve of points, arc, curve of points.

The main condition for this geometric figure is the constant distance between two points lying on the surface of the camera, connected by a straight line passing through its center, located in the same plane.

The rotor together with the shaft, located in the chamber, is closed by the engine cover - part 10, the tightness of the rotor body with the chamber is provided by the O-rings - part 11. (shown in Figs. 3, 4, 9).

As the rotor rotates, each of the cylinder chambers makes three expansion strokes and three compression strokes in one revolution.

The rotor can have either a circle or any other shape at its base. The rotor, together with the blades, serves as both a piston and a gas distribution mechanism and a crankshaft.

Implementation of the invention.

The presented rotary vane engine can be used in road transport, sea and river fleet, boats, aviation, construction and road equipment, stationary power engineering.
