ABSTRACT:
A hydraulic turbine is of the kind having a distributor including a passage, without blades therein, which communicates with the movable blades of a rotor, having four blades, by means of injectors constituted by gaps formed between adjacent portions of a circular ring, the number of which is double that of the blades. The water escape axially to the center of the rotor chamber. The improvement of the present invention is that, in combination, the blades have a profile of an arc of a circle, and the portions of the stator ring which define the injector gaps each have a plane terminal face inclined at substantially 45.degree. to the corresponding radius of the respective portion of the ring and, for a first injector, forming an angle of substantially 135.degree. with a plane tangential to the external surface of the corresponding blade, when that blade occupies a position in which an adjacent blade is about to cooperate with the respective injector.
