ROTOR OF CENTRIFUGAL TURBOMACHINE

Subject of the invention is a new construction of centrifugal turbomachine, for example compressor, pump, fan which generates a pressure difference and a volume fluid flow. The rotor (1) of the centrifugal turbomachine according to the invention features a lower wall or hub (4) and an upper wall (3) which is attached to the axis (5) of the turbomachine, while the structure or the porous or cell-structured material (2) fills in the radial direction from the pivotal point towards the circumference at least a part of the rotor (1) meaning preferably up to the circumference of the rotor, while the driven fluid travels in the radial direction through the porous or cell-structured material (2). Predmet izuma je nova konstrukcija rotorja centrifugalnega turbostroja, na primer puhala, ŽŤrpalke, ventilatorja, ki generira tlaŽŤno razliko in volumski pretok fluida. Rotor (1) centrifugalnega turbostroja po izumu ima spodnjo steno ali pesto (4) in zgornjo steno (3), ki je pritrjena na os (5) turbostroja, pri ŽŤemer struktura poroznega ali celiŽŤnega materiala (2) izpolnjuje v radialni smeri od vrtišŽŤa proti obodu vsaj del rotorja (1) in to prednostno do oboda rotorja, pri ŽŤemer gnani fluid potuje v radialni smeri skozi porozni ali celiŽŤni material (2).
