    摘要： The hydraulic machine comprises a runner, adapted to rotate under the height of a water fall, a distributor with adjustable guide blades (120), and a first electronically piloted servomotor (30) to open the guide blades. The first servomotor (30) is not able to open the guide blades (120) further to a predetermined position. The machine includes a second servomotor (36), which is mechanically piloted by the height of the water fall and which is adapted to open the guide blades further to the predetermined position in low water fall conditions. Preferably, the hydraulic machine is a turbine.

    摘要： The Pelton turbine wheel according to the invention comprises several buckets (14). Each bucket (14) comprises an intrados surface turned toward a preceding bucket (14') and intended to receive a jet of water and an extrados surface turned toward a following bucket (14"), as well as a trailing edge (24) that connects the intrados surface and the extrados surface. The intrados and extrados (24) surfaces are formed by the structural portion (18) of the bucket that is made from a first material. Each bucket (14) comprises at least one part (30, 32) made from a second material different from the first material. That part (30, 32) is fastened on each bucket (14), either in the vicinity of the training edge (24), extending beyond the trailing edge, in the orthoradial direction and toward the preceding bucket (14'), or on the extrados surface (22), while extending beyond the extrados surface (22), in the orthoradial direction and toward the following bucket (14"). The attached part (30, 32) forms a screen that participates in confining the jet of water received in the bucket (14).
