Abstract
Abstract Control apparatus, for hydraulic pumps and reversible turbines, comprising adjustable vanes or blades and servomotors therefor, each blade being pivoted to a piston rod of a servomotor through the intermediary of a lever. The casings of the servomotor are kinematically connected with respective adjacent blades. This connection is effected through the intermediary of double-armed levers, one arm thereof being connected to the piston rods of the associated servomotors, and the other arms to the casings of the servomotors of the respective adjacent blades.
