Vynález sa týká rotačného stroja a pomocnými rotormi a výhradně rotačným pohybemjeho pracovných časti, ktorý sa dá použit ako nsregulačný hydromotor, čerpadlo, alabokompresor. Slúži k premene prúdiacej tekutiny na mechanickú snergiu, alsbo naopak.BACKGROUND OF THE INVENTION The present invention relates to a rotary machine and to auxiliary rotors and solely to a rotary movement of its working part, which can be used as a non-regulating hydraulic motor, pump, and acompressor. It serves to convert the flowing fluid into mechanical energy or vice versa.

Známa stroje tohoto druhu majú nevýhodu v tom, že nedostatočne uzatvárajú pracovnýpriestor, pracujú s malou účinnostou a zatažujú ložiská rotorov velkou radiálnou silouod tlakovej kvapaliny.Known machines of this kind have the disadvantage that they inadequately close the working space, operate with low efficiency and retract the rotor bearings with a large radial silo of the pressurized fluid.

Uvedené nedostatky z časti odstraňuje rotačný stroj s pomocnými rotormi pozostáva-júci z nehybnej skrine., v ktoraj sú vytvořené kruhové komory opatřené vstupnými a výstup-nými otvormi pre pracovně médium a v ktorých sú otočné uložené rotory s lopatkami a vy-braniami, pričom rotory majú vzájomne viazaný pohyb prostrednictvom ozubeného súkolia,kde rotačný stroj s pomocnými rotormi podlá vynálezu má Jsdsn hlavný rotor opatřený aspoňČtyřmi, alsbo viac lopatkami profilu hlavy zuba ozubeného kolesa s evolventným ozubenim'avedla každsj lopatky js vytvořené vybranie profilu časti zubovej medzsry evolventného ozu-benia a rotorový stroj s pomocnými rotormi má právě čtyři pomocné rotory vybavené po jed-nej lopatko profilu hlavy zuba evolventného ozubenia a vedla lopatky vybranie profilučasti zubováj medzery evolventného ozubenia. Priemer valcovej plochy hlavného rotora jetolkokrát vačči, ako priemer pomocných rotorov, kolko má hlavný rotor lopatiek. Styripomocné rotory sú uložené na obvode hlavného rotora tak, že sú po dva vedla seba a dvoji-ce pomocných rotorov sú oproti sebe posunuté o 180°. Dva vstupné otvory pre pracovně mé-dium sú v nehybnej skrini umiestnené za každou dvojicou pomocných rotorov a sú vzájomne po-sunuté o 180°. Dva výstupné otvory sú umiestnené v nehybnej skrini před každou dvojicoupomocných rotorov vzhladom na směr otáčania hlavného rotora a sú taktiež vzájomne posunutéo 180°. Výhodou rotačného stroja s pomocnými rotormi je, že lopatky rotorov pri přechode cezvybranie spoluzaberajúceho rotora nemajú tesniacu funkciu, čo umožňuje lepčle uzatyáraniepracovného priestoru, rotačný stroj s pomocnými rotormi Je k'ončtrukčne a výrobně Jednodu-chý, včetky jeho pracovně časti konajú výlučné rotačný pohyb, čo umožňuje vysoké obrátky,má kludný chod s končtantným a vysokým krútiacim momentom, má malé rozměry a malú hmotnost.Oeho hlavný rotor, ktorý má velký priemer, je hydraulicky vyvážený a nezatažuje svoje lo-žiská velkými radiálnymi silami od tlaku kvapaliny. Oeho pomocné rotory, ktoré majú čtvor,alebo viacnásobne menši priemer ako hlavný rotor, majú čtyřikrát, alsbo viackrát vyččieobrátky, ako hlavný rotor, čo zmenšuje straty netesnostou. Poměrně dobré těsni pracovnýpriestor a Je vhodný aj pre použitie s velkými rozmermi a velmi vysokými výkonmi, aj prepoužitie s velmi malými rozmermi.The above drawbacks are partly eliminated by the rotary machine with auxiliary rotors consisting of a stationary housing in which circular chambers are provided with inlet and outlet openings for the working medium and in which the mounted rotors with blades and recesses are rotatable, the rotors being rotatable. having a mutually coupled movement by means of a gear assembly, wherein the rotary machine with auxiliary rotors according to the invention has a main rotor provided with at least four or more blades of a toothed toothed toothed toothed rack, each of which has been provided with a profile of the involute tooth portion of the toothed spacer portion and the rotor machine with auxiliary rotors has just four auxiliary rotors equipped with an involute gearing head profile after one blade profile and guided the blades to a recess of the involute gearing tooth profile section. The diameter of the cylindrical surface of the main rotor is as many times as the cam, as the diameter of the auxiliary rotors, how many have the main rotor of the blades. The styrofoam rotors are disposed on the perimeter of the main rotor so that they are two-way apart and the pairs of auxiliary rotors are 180 ° offset from each other. The two inlet openings for the working medium are located behind each pair of auxiliary rotors in the stationary housing and are displaced 180 ° to each other. The two outlet openings are disposed in the stationary housing in front of each bipolar rotors relative to the direction of rotation of the main rotor and are also 180 ° relative to each other. An advantage of the rotary machine with auxiliary rotors is that the rotor blades do not have a sealing function during the transition of the co-engaging rotor selection, which allows the sealing of the working space, the rotary machine with the auxiliary rotors is simple and easy to operate, including its rotational movement, which allows high revolutions, has a quiet running with a constant and high torque, has small dimensions and low weight. Its main rotor, which is large in diameter, is hydraulically balanced and does not load its bearings with great radial forces from the fluid pressure. The auxiliary rotors having a four or more smaller diameter than the main rotor have four times or more reads as the main rotor, which reduces leakage losses. Relatively good working space and It is also suitable for use with large dimensions and very high performance, as well as use with very small dimensions.
