Abstract:
1. 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), which comprises a first valve ( 1 ) provided with a control ( 2 ) mounted in a pipe ( 10 , 11 , 12 ) connecting the two reservoirs (H, S), a Laval nozzle ( 3 ) located downstream of the first valve ( 1 ) and provided with an electric pressure-drop sensor ( 4 ), a second valve ( 5 ) provided with a control ( 6 ) connected between the downstream part of the Laval nozzle and an exhaust orifice (R) and finally 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 ) so as to regulate the flow rate and/or the pressure of the fluid transferred from the first reservoir (H) to the second reservoir (S).
