Abstract
The invention concerns a system for successively producing fluid flows at staggered values. This system includes for example an epicycloidal differential of which a shaft is coupled to an engine, and the other two shafts to two pumps respectively producing the maximum necessary flow and producing the minimum flow; to each pump is connected a brake; when the circuit, for example a jack, fed by this system becomes saturated, the pressure of the fluid sent by the high flow pump increases and reaches a threshold detected by a pressure detector-switch, the latter applies the brake which stops the pump and releases the brake of the other pump. The invention is applicable for example to feeding hydraulic jacks, in particular for turboshaft engines.
