Hydraulic turbine

An impulse turbine comprises at least one runner (10; 110; 210) provided with a plurality of blades (14; 14a; 114; 214) and adapted to rotate about an axis of rotation (A) as a result of the delivery of a pressurized fluid to the blades (14; 14a; 114; 214) through fluid delivery means which include...

Beschreibung
Zusammenfassung:	An impulse turbine comprises at least one runner (10; 110; 210) provided with a plurality of blades (14; 14a; 114; 214) and adapted to rotate about an axis of rotation (A) as a result of the delivery of a pressurized fluid to the blades (14; 14a; 114; 214) through fluid delivery means which include at least a nozzle (20; 120; 220) facing an active surface (22; 22a, 22b; 122; 222) of the blades. Each nozzle (20; 120; 220) includes an outflow portion (20a; 120; 220a) lying substantially in a general plane of the runner (10; 110; 210) and extending in an inner zone of the runner between the blades (14; 14a; 114; 214) and the axis of rotation (A). The outflow portion (20a; 120; 220a) of the nozzles (20; 120; 220) is directed towards the outside of the runner (10; 110; 210) along a direction parallel to and spaced from the radial direction of the runner, and each blade (14; 14a; 114; 214) of the runner (10; 110; 210) define an arched path extending transversely to the plane of the runner (10; 110; 210).
