Scheme of the rotary engine. with the planetary movement of the working elements. Classification of rotary engines! Pele 1 When introducing any new type of engine, certain standards are established. First of all, this refers to the classification terminology. It is premature to establish a more precise terminology for taxiways in our country, where their distribution is considered to be single experimental samples and samples.

Therefore, arbitrary terminology on the conceptual and analogue prints is used in this work. The current classification of inventions of the USSR in class 46, called “Internal combustion engines with rotating pistons, oscillating pistons, etc.” provides for the division into the following {sub-class: I. and with stop blades 2. Engines with 11 opimie BI 1MH Gates 3. Engines with pivoting stops 4, engine 11 with oscillating parts located on a piston drum or washer Engines with pistons: 501 – alternately rotating and stopping; piston engagement with each other 7. Engines with swinging blades etc. 11 8, engines with a liquid ring 9. Special designs 10. Parts of engines In class 123 of the US classification, called “Internal rotor engines cr0 I ”, there are the following subclasses: I. Rotary engines, engines with a variable law of motion of pistons 3. Engines with pistons driven by gears MH 4. Engines with ro! iaio! Cushion shutters 5, Motors with sliding shutters 6, Motors with oscillating shutters 7. Sliding piston engines.

8, engines with oscillating pistons. They are of no interest. 9. Engines with pistons making an oscillatory motion. RD classifications in the rest of the countries are less developed. Analysis of these classifications allows us to draw the following conclusions. In the classification, a typical system of structural evaluation is used, which is convenient only for patent organizations. Classifications were made as the various engine structures accumulated, the main principle of uniting of which was the difference from the schemes commonly used in PD. As a result, they are not fundamental, and the classification of possible constructions is limited to the options listed above.

The appearance of new constructions will require a change or addition to the existing class! Orientations A very insignificant place in classifications is reserved for rotor engines themselves. So, in class 46 of the classification of inventions of the USSR, the subclass “Rotary engines” is generally absent and, apparently, belongs to subclass 9, including “Special designs”. Of the nine subclasses of the US classification, only one is inclusive. rotor engines, which in no way justifies the common name of the class 123. In this sense, the name of the class 46 classification of inventions of the USSR is more equitable. and with other tees. pami It is also not possible / to establish the principal advantages of engine deficiencies even in the most general form to assess their prospects.

Thus, the above classifications can be used. be in the narrowest direction, which is mainly interested in patent organizations n. In this connection, it became necessary to develop a basic classification of internal demilitarization RDs, devoid of the listed deficiencies. The classification proposed below is based on the following signs: the working element movement, the presence and nature of the sealing element movement. understand the rpynny of the parts, reconstructing the pressure in the working chamber, ra3ov, and transforming the ero into rotational force motion. In the piston engine, this working element is the group s parts movable part crank – mechanism (hand, connecting rod and crankshaft parts group) in the rotary engine, as shown above, as the operating element depending on the constructive circuit 42 may

blades, sectors, dampers, rotors, etc. d. Motors with oscillating, oscillating, alternately rotating, moving unevenly! Pistons should not be rotary. Strictly speaking, they are transition types of piston engines with modified structural schemes. Despite this, they are included in the proposed classification, as they are now in patent classifications and in large | In the literature, they are completely unreasonably attributed to a rotary-piston (rotary piston, rotary, rotary, even rotary) engine.


The nature of the movement of the work item determines the engine forcing speed and, consequently, the possibility. Improvements in specific weight, weight, and, to a certain extent, economic indicators of ero work. These parameters serve as a criterion for assessing the prospects of engines and comparing them among themselves and with existing types of engines. In this regard, the nature of the movement of the working element is given as the first sign of the proposed classification.

The presence and nature of the movement of the sealing elements determine the reliability of sealing the working chambers and separating them from each other. On this depends the cause of gas and heat losses. the quality of the workflow, the allowable compression ratios, the ability to use the workflow with a self-powered Meliciil! from compression, the nature of the rifle and the degree of wear of the sealing elements of the main engine parts. These factors ultimately determine the sustainability of the economics of the work of the 6 IT of the process, the reliability and durability of the work. Classification of the FD inside williero cropa11i is shown in Fig. 10 The existing types of RD are divided into two parts according to the first attribute. The first includes the taxiways, the working element of which makes the sign ° variable return – translational motion: with return – the translational movement of the pistons ; with a complex movement of working elements The second part combines taxiways, whose working elements perform an unambiguous rotational movement, in turn, is divided into two groups. The first combines the engines, the working points of which perform an unambiguous rotational motion of OM and ro with variable angular velocity, t. e. do not obey the law on const at steady state of the engine dt operation. The group consists of taxiways with non-uniform: 10 rotating pistons . The second group includes engines oc with work elements, with an unambiguous rotational movement with constant y velocity at steady state operation. The most numerous rpynne engines include: _ with sealing blades ;

The principal classification of the rotor engines According to the second feature of the new classification, each of the transfer diagrams of the taxiway can be attributed to one of four possible sealing systems shown in the bottom row. The new classification has been compiled according to the same principle principles, allowing the dragons to include all the main design schemes of the RD inside the nero cropains into one system. Anya can determine The possibilities of development sist essentially performance, compactness, dale. r ° eternity and taxiway safety and to judge so their promising nature.

Liz designs of existing and created by RD and it becomes possible to compare them with each other and with other types. So, I have a PD with a working element making a sign of variable movement and sealing elements! There are no similar movements, no advantages over 111, and, as was shown above, they are unpromising. There are more promising ways to have a working element with unambiguous rotational movement at a constant angular velocity with fixed sealing elements.

These engines maximize their properties on the floor. Ch. Wankel and W. Frede. Its rotor rotates in one direction with a constant angular velocity. Mechanical seals are fixed relative to the rotor in which they are placed. The radial sealing plates on the large part of the rotor rotation are also practically immobile relative to the rotor. Only at the points of inflection of the corps they are committed. the sign of variable, negligible in magnitude, alternates, 1 is no doubt that it is thanks to such a successful
