The regulator includes two principal chambers (1,2) separated by a membrane (3), a pair of secondary chambers (4,5) sharing respectively the principal chambers. A part of a common wall (6) is positioned on either side of the membrane, with two valves (8,9) respectively formed in part of the shared wall. coupling (14) links the heads of the valves to each other and to the membrane. The two chambers have respectively a second and a third membrane (17,18) of equal area, with coupling (15,16) between the second and third membranes and the first coupling (14). A supply line (60) couples the pressure of the fluid contained in the principal chambers onto the second and the third membranes. |
