Abstract (en)
[origin: WO2017129906A1] The invention relates to a pressure control system (100) for controlling the pressure in a fluid line (16A), such that said pressure complies with a given control criterion. The system comprises a valve (20A) with on/off control, which is disposed at a downstream end of the line (16A) and which can pivot between an open position and a closed position; a pressure sensor (40A) connected to the line (16A), for measuring the pressure in the line upstream of the valve (20A); and a control unit (50) configured to send the valve (20A) open/close commands determined according to the measured pressure. These commands impose open periods (Oi) on the valve at a fixed frequency. The length of said open periods is varied such that the pressure in the line complies with the given criterion.
