ABSTRACT:
The device is used to operate a cylindrical gate which is used to protect and/or seal a hydro-electric installation including hydraulic turbo-machines; a set of hydraulic servomotors are distributed above the circumference of the cylindrical gate and connected with it by means of operating rods; each servomotor includes a cylinder and a piston; a minimum of three servomotors are interconnected between themselves, and a synchronizing device connects those interconnected servomotors; each servomotor includes a nut, thrust bearings, a threaded rod going through the nut and the thrust bearings to allow translation of the piston in the cylinder and to change this translation into a rotation.
