| 摘要 |
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).
