    摘要: The invention relates to a machine through which a main flow (E) of water passes, including a turbine wheel (4), with at least a turbulent zone, reduced-pressure zone or cavitation zone (8, 10, 33) being formed close to said wheel. The wheel includes blades (6) disposed between a ceiling (28) and a belt (30). The machine also includes means for injecting a flow (E2) drawn from the main flow into the aforementioned zone (8, 10, 33) such as to alter the main flow (E) locally or increase the pressure in said zone (8, 10, 33). Said injection means inject the drawn flow (E2) from the ceiling (28) or from the belt (30) through holes (31, 32) provided in the ceiling (28) or belt (30).

    摘要: This wheel comprises a plurality of vanes (2) arranged on a crown (3) and is equipped with a tip-forming member (10) attached to a central region (32) of the crown or hub of the wheel (1), radially inside the vanes (2), the crown defining a wet surface (31) for guiding a flow (E) passing between the vanes. The tip-forming member (10) is provided with at least one opening (121) for diverting a fraction (E1) of the flow towards the internal volume (V10) of this member. This member comprises a frustoconical annular skirt (11) and at least one fin (15) arranged in its internal volume (V10) and able to modify the path of the flow fraction (E1) entering this volume through the opening (121). This fin (15) extends as far as the edge (112) of the skirt (11) which defines an outlet opening (14) of the member (10) for the flow fraction (E1).

    摘要: The invention relates to a Pelton machine through which a main flow (E) of water passes, including at least one Pelton turbine (54) manifold (56), with at least a turbulent zone or a reduced-pressure zone (64) being formed close to said manifold. The machine also includes means for injecting a flow (E4) drawn from the main flow, and unaltered in relation to the main flow (E), into the turbulent or reduced-pressure zone (64) such as to alter the main flow (E) locally or increase the pressure in said zone (64).
