ABSTRACT:
The present invention relates to a device for regulating the flow rate and/or the pressure of a fluid transferred from a high-pressure reservoir (H) to a reservoir (S). A first valve (1) provided with a control (2) is mounted in a pipe (10, 11, 12) connecting the two reservoirs (H, S). A Laval nozzle (3) located downstream of the first valve (1) is provided with an electrical pressure-drop sensor (4). A second valve (5) provided with a control (6) is connected between the downstream part of the Laval nozzle and an exhaust orifice (R). A micro-programmed system (7), designed to receive the values read by the pressure-drop sensor (4) and to drive the two controls (2, 6) of the two valves (1, 5) makes it possible to regulate the flow rate and/or the pressure of the fluid transferred from the first reservoir (H) to the second reservoir (S).
