Abstract

Improvements in hydraulic machines essentially in the armor of a hydraulic machine wheel (1), such as a turbine, a pump or a turbine-pump, characterized in that the parts of this armor intended to form a joint (10) with corresponding parts (17) of the wheel (1) are mobile and capable of occupying two positions, the first one ensuring a minimum play (d) with respect to the wheel (l) for the normal running of the machine, the second providing a maximum play (D) with the wheel (1) to allow it to be dragged empty, without heating the imitation (10).
