<p>The invention relates to an impeller comprising a round disk (4) and a round annular disk (5), that is provided with a round suction inlet (6) for receiving fluid inside the impeller (2)and in between the round disk (4) and the round annular disk (5) arched blades (7), which are attached to the round disk (4), and to the round annular disk (5) so that blade ducts (8) are formed in between the arched blades (7) for removing fluid from inside the impeller (2). The horizontal section shape of the arched blades (7) forms part of a circular arch (9), the center of the curvature (10) of said circular arch (9) being located at the distance 0.7R - 1.3R from the center axis (11) of the impeller (2), where R is the radius of the impeller (2). The invention also relates to a turbine device.</p> |
