Abstract (en)
[origin: FR2670824A1] A device is provided for remotely operating an assembly by varying the flow of an optionally incompressible fluid. The device comprises means (17) for coupling the device to the assembly to be operated, and a set of two elements (4, 5; 10, 11; 20, 24) which co-operate to control the opening value of the fluid flow channel. Said device is characterized in that a control assembly (8) sets the opening value at either one of two specific values.
