Zusammenfassung:The invention relates to a rotary duster used to vacuum in hardly accessible places and from unstable objects, with a mechanical system of rotational speed control, the device being able to be mounted to the hose of a vacuum cleaner. According to the invention, the device consists of a stator (A) and a rotor (B) which are coaxially assembled by means of a bearing (C), where the rotor (B) is provided, at the cylindrical end (B1) situated inside the stator (A) with an axial-type turbine (1), without central axle, the blades of which, directed towards the rotation axis, are integral with the interior circumference of the rotor (B), they being configured right from the body thereof, on the tapered portion (B2) situated outside the stator (A), the rotor (B) is provided with some brushes (2) with flexible bristles made of electrostatic microfiber and with suction slots (3), the entire mechanical speed control system (D) being mounted with an elastic sleeve on the stator (A), and a screw and spring mechanism exerting a variable pressure on the rotor (B). Invenţia se referă la un pămătuf rotativ, utilizat pentru aspirarea prafului din locuri greu accesibile şi de pe obiecte instabile, cu sistem mecanic de control al vitezei de rotaţie, dispozitivul putând fi montat la furtunul unui aspirator. Dispozitivul conform invenţiei este alcătuit dintr-un stator (A) şi un rotor (B) care sunt asamblate coaxial, prin intermediul unui rulment (C), rotorul (B) fiind prevăzut, la capătul (B1) cilindric aflat în interiorul statorului (A), cu o turbină (1) de tip axial, fără ax central, ale cărei palete, îndreptate către axa de rotaţie, sunt solidare cu circumferinţa interioară a rotorului (B), fiind configurate chiar din corpul acestuia; pe porţiunea (B2) tronconică aflată în exteriorul statorului (A), rotorul (B), are prevăzute nişte perii (2) cu fire flexibile, din microfibră electrostatică, şi fantele (3) de aspiraţie, întreg sistemul (D) mecanic de control al vitezei montându-se cu manşon elastic pe stator (A), iar un mecanism cu şurub şi arc exercită o presiune variabilă asupra rotorului (B).
