More Information
Summary:A pressure regulator system (100) for regulating a pressure in a fluid line (16A) in such a manner that the pressure complies with a predetermined regulation criterion. The system comprises a valve (20A) that is controllable in on/off mode arranged at a downstream end of the line (16A) and suitable for oscillating between an open position and a closed position; a pressure sensor (40A) connected to the line (16A) and serving to measure the pressure in the line upstream from the valve (20A); and a regulator unit (50) configured to transmit to the valve (20A) open/close commands that are determined as a function of the measured pressure. A constant frequency imposes open periods (Oi) on the valve. The durations of the open periods are modulated in such a manner that the pressure in the line complies with said predetermined criterion.
