Abstract
Device for hydraulic control of thrust reversal units activated by jacks in jet engine. The jacks are connected to a rotary hydraulic engine fed by a hydraulic circuit which involves a mechanism for slowing down the speed of the reversal units when they approach the stop units. The hydraulic circuit allows for directly subjecting the engine's capacity to the opposing load on the engine. Application of this invention is possible to a dual flow turbojet in which the reversal units rotate in the cold flow.
