Abstract
A hydraulic installation includes a gate valve and an injector rectilinearly mounted in series in a water inlet conduit which feeds a turbine. The injector includes a central body portion in which first and second servo-motors are housed. The first servo-motor controls the tip of the injector and the second servo-motor controls the movement of the plug of the gate valve. A single crosspiece secures the injector to an outer annular casing and also absorbs hydraulic forces otherwise exerted on the gate valve and the injector.
