ABSTRACT:
A system for shutting down a hydraulic machine having a runner mounted on a rotating shaft and a stationary part or parts surrounding the runner, comprising a rod or rods installed on the stationary part or parts opposite to the periphery of the runner, each rod being yieldable to the pressure of the runner, in case of the latter's deformation or off-center displacement, so as to sense the gap between the runner and the stationary part, a member or members each adapted to be actuated when the stroke of the associated sensing rod has exceeded a predetermined value, and a shutdown device operable upon actuation of the said member.
