Abstract

a) Installation hydraulique. b) Elle comprend un puits 1 de liquide, une source 2 de liquide sous pression et entre eux une valve 3 de régulation pour commander l'écoulement qui va au puits 1, cette valve 3 etant commandée par un transducteur 4 à impulsions. Des moyens 6 d'étranglement sont prévus dans le conduit 5 entre la source 2 et le puits 1. Une vidange à moyens 8 d'étranglement communique avec le conduit 5 en amont des moyens 6 d'étranglement c) Turbine à gaz.
