Abstract
A device controls the movement of a ring gate of a hydraulic machine between an open position and a blockage position. The device includes at least four cylinders, the rods of which are suitable for being connected to the ring gate at locations located on a perimeter of the ring gate. The device also includes at least two hydraulic members for synchronizing pistons, the hydraulic synchronization members being connected to the cylinders such as to form at least two groups. Each group encompasses at least two cylinders connected by at least one hydraulic synchronization member, two cylinders belonging to two separate groups not being connected by a hydraulic synchronization member.
