Abstract

The motor comprises a body (1) with suction chambers (2) of the same form and dimensions, the expanding chambers (3) being symmetrically arranged within it at such intervals that during rotation of the rotor (7) the sum of the moment radiuses describing the points of any two adjacent plates (8) is always the same. The number of plates (8) in the rotor (7) is such that there are four plates (8) symmetrically arranged in the rotor for each pair of suction chambers (2) and expanding chambers (3). Any two adjacent plates (8) are balanced and synchronized by a mechanism comprising axles (10) whoseends run out of the two sides of the rotor (7), and there is a rocker placed on each end of the axles (10), the two ends of each rocker entering the lower ends of two adjacent plates (8). The motor can be with internal or external carburation, with forced or self-ignition, air-injection or atmospheric, and may be used for driving stationary or mobile machines.

Description

The invention relates to rotary internal combustion engines.

State of the art

Known rotary-plate internal combustion engines with an elliptical inner surface of the housing (DE4422 720 A1; US0054151141 A; Bulgarian Patent 37627) or with other complex internal surfaces (DE3301364A1) in which the plates move continuously during working hours and when the forces acting on the plates of the engine are very large, especially during expansion, and from there the wear of these engines is very intense.

The plates aim at their upper end to circumvent the inner surface of the housing during rotation of the rotor under the action of centrifugal forces created by them (DE 3301364A1; Bulgarian Patent 376227) or by the action of centrifugal forces and forces created by springs (US3,835,818 DE 19751495 A1).

These centrifugal forces are very large especially at high speeds and lead to wear of the friction parts as well as to a decrease in mechanical efficiency. of the engine. These forces are absorbed in some known motors by special pins made at the bottom of the plates which enter special grooves on the side walls (US005415141A1), requiring very high precision of manufacture, and in some cases especially by smaller motors The pins at some point approach the channel walls at a very large angle.

Most of the known internal combustion rotary engines have no gas balance (US005415141A1; DE 4422720A1), which results in vibrations and high load on the bearings.

Technical nature

It is an object of the invention to provide a compact and efficient internal combustion rotor motor with maximum centrifugal force balancing and gas force balancing resulting from the workflows of the invention.

The problem is solved by means of a rotary symmetric motor including a housing in which there is a circular main opening in which a rotor with radially moving plates is inserted therein. There is an opening in the center of the rotor in which the main shaft is fixed. On both sides, the housing and rotor are closed with side walls fixed to the housing. In the center of the lateral sets there is an opening for free passage of the main shaft and places for mounting the bearings in which it camps.

Inside the housing are cavities with a larger radius than the radius of the circular main orifice. The two radii of each cavity are interconnected smoothly by symmetrical curves. These cavities, together with the rotor and side walls, form chambers that are uniform in shape and size and are symmetrically arranged in the housing at uniform intervals. So when rotating the rotor the sum of • · · · · · · · · · · · · · 9 9 9 9 * ·· ··· 9 9 999

We need to have at least two such cameras in the hull. The first suction in it is the suction and compression process, and the second, which is the same in shape and size of the first expansion chamber, in which the expansion and release processes take place. The total number of chambers in the housing must be read and the number of intake chambers must be equal to the expansion chambers. Each suction chamber is connected to a suction port, and each expansion chamber with a discharge port in the gap between these chambers in a threaded hole is a spark plug or fuel injection device fitted, a fuel spray device may also be provided in the suction chamber.

In the rotor, radial slots are cut symmetrically, in which the plates of each pair of suction chambers move and the expansion chamber in the housing corresponds to four pieces of rotor in each. Between each two plates, combustion chambers are symmetrically carved outwardly into the rotor, the number of which is equal to the number of plates. Above the level of the lower edge of the radial slots perpendicular to the rotor, round holes are cut symmetrically, which is twice less than the number of plates; each hole is located midway between two adjacent plates. Axles are inserted in these openings. The two ends of these axes extend from both sides of the rotor. On each of the two ends of each axis, one rocker is placed, swinging freely around the axis. The opposite ends of each rocker enter two adjacent plates at the bottom. For this purpose, special slots are cut at the bottom of each plate on both sides. From • 4 above, grooves for sealing plates are cut lengthwise on each plate.

In this way, the centrifugal forces created by the plates are balanced, ensuring the synchronization of their movement and a very good crawl on the outside of the plates along the inner surface of the housing.

In the case of the above-described shape of the chambers in the housing for the greater part of the time during which the rotor rotates and when the pressure in the expansion chamber is at its highest, the plates are stationary in a radial direction.

Q For rotary symmetric motors in which we have at least two or more pairs of suction and exhaust chambers, a complete balance of the gas forces is achieved in its normal operation.

Example of implementation

1 and 2 show a rotary symmetric motor with two pairs of suction chamber and an expansion chamber in two different projections.

The rotary symmetric motor of the present example consists of a housing (1) with a circular main opening, in which a larger radius and a smooth symmetrical transition between it and the radius of the circular main opening The openings are formed by the cavities of four uniformly sized and symmetrically arranged chambers, two intake chambers (2) and two expansion chambers. (3) symmetrically arranged with respect to the horizontal axis of symmetry. Each suction chamber is connected to a suction port (4) and each expansion chamber to a discharge port (5). In the middle of the interval between each pair of suction chamber (2), an expansion chamber (3) is screwed into a threaded hole by one spark plug (6).

The rotor (7) is inserted into the circular main opening of the housing (1), providing the minimum clearance necessary for its free rotation. Eight slots are cut symmetrically through 45 ° in the radial direction of the rotor. In each of them there is one plate (8), four pieces for each pair of suction chamber and exhaust chamber, between each two plates on the outside of the rotor is carved one combustion chamber (9) in total eight in number.

At a level above the lower part of the radial slots along the rotor, four holes are drilled symmetrically through 90 ° so that each hole is midway between two of the adjacent radial slots. Four openings (10) are crammed into these openings, with their two ends protruding from each side of the rotor at each end of the axles (10) and one rocker (11) is mounted freely. The two ends of each rocker (11) enter freely two adjacent plates (8) into slots cut into the lower edge of the plates (8) on their two sides. A longitudinal groove for the sealing plates (12) is cut at the top of the plates (8). A longitudinal hole is drilled in the center of the rotor (7) in which the main shaft (13) is fixed.

The housing and rotor are closed on both sides with side walls (14) fixed to the housing (1) and providing minimum clearance of the rotor (7) for its free

rotation. In the center of these side walls is an open hole for free passage of the main shaft (13) and there are beds for the bearings (15) on which it camps.

Application of the invention

When the rotor is rotated in the housing under the influence of the plates, a four-stroke duty cycle is performed by suction and compression in the suction chamber, the compressed mixture is ignited in the combustion chamber and expanded and expanded in the expansion chamber. When there are at least two pairs of suction and expansion chambers in the housing and they are arranged symmetrically and there are four symmetrically arranged plates in the rotor for each pair of chambers, a complete equilibrium of the gas forces in one contour of the rotor symmetric motor is obtained.

As the rotor rotates, the plates create large centrifugal forces, which are absorbed and balanced by the rocker arms and, through the axles, are absorbed from the inside of the rotor, and not transmitted to the housing, where excessive friction forces would occur between the housing and the plates. In addition, they help to synchronize the movement of the plates and to crawl them tightly over the inner surface of the housing.

When the housing is fixed, a rotary motion is created on the main shaft that can drive stationary and mobile machines.
