<p>Disclosed is a rotary vortical machine, comprising a stator (1) and rotor (2). These two elements define an annular working chamber (3) which is disposed between them and connected to ducts for supplying and draining a working medium. The working chamber (3) contains blades (4) and a separator (5) connected to the stator and the rotor, respectively. Each blade (4) comprises a leading edge (6), inclined towards the rotor (2). The separator (5) comprises severed edges (9) defining a portion of the separator surface which is inclined towards the leading blade edges. The orientation angle α of the leading blade edge ranges from 20 to 70°, and the angle of incidence β of the blades ranges from 0 to 26°.</p> |
