Abstract
The invention relates to a process and device for regulating at any instant the speed of a mobile member, such as a pulley, moving in a stroke of determined uniform direction, by employing a fluid passing under pressure through an orifice of restricted section. According to the invention, said pressurized fluid is made to pass several times alternately in one direction and in the other through said orifice, during said stroke of determined uniform direction. The invention is more particularly applicable to the deployment of appendices mounted on board space vessels.
