A device for controlling the opening and the closure of a valve includes rotatable element configured to control the position of the rotary valve on the basis of its rotation in a direction or in the opposite direction; and a system that causes the rotation of the rotatable element and includes two antagonist feeder conduits that generate a linear motion. The rotatable element is shaped as a pulley and the system that causes the rotation further includes a wire anchored to the pulley and to the feeder conduits to cause the rotation in a direction or in the opposite direction of the pulley based on the application of a pre-determined traction on the wire obtained through the linear motion generated by the feeder conduits.

1. A device (1) for controlling a position of a rotary valve, comprising: a rotatable element (11) disposed in a housing (4) and configured to control the position of the rotary valve based on a rotation in a direction or in an opposite direction; andmeans (21, 22, 30, 50, 54, 52) to cause said rota
1. A device (1) for controlling a position of a rotary valve, comprising: a rotatable element (11) disposed in a housing (4) and configured to control the position of the rotary valve based on a rotation in a direction or in an opposite direction; andmeans (21, 22, 30, 50, 54, 52) to cause said rotation of the rotatable element (11), said means comprising,a first and a second antagonist feeder conduits (2, 3) coupled to the housing, said first and second antagonist feeder conduits (2, 3) each respectively having first and second upper plates (2′, 3′) and first and respectively second bottom plates (2″, 3″), the first and second bottom plates being disposed on the housing (4);a first septum (30) slidingly disposed inside the first feeder conduit to have a linear motion by action of a pressurized fluid injected between the first septum (30) and the bottom plate (2′),a second septum (52) slidingly disposed to have a linear motion inside the second feeder conduit, anda biasing member arranged between the second septum (32) and the second bottom plate and acting on the second septum to cause the second septum to return to an initial position after the first feeder conduit is depressurized,wherein said rotatable element (11) is a pulley and said means (21, 22, 30, 50, 54, 52) further comprises a wire (21, 22) anchored to the pulley and to said first and said second septa to cause a rotation in a direction or in an opposite direction of the pulley due to application of a pre-determined traction on the wire obtained through the linear motion generated by said first and second feeder conduits, andwherein no pressurized fluid is injected between the first and respectively the second upper plates and the first and respectively the second septum. 2. The device (1), as per claim 1, wherein there is a single wire (21, 22) having two ends and connected directly to the pulley in an area comprised between said two ends. 3. The device (1), as per claim 1, wherein there are two wires (21, 22) each having a first end connected directly to the pulley and a second end anchored onto the first and respectively the second septum. 4. The device (1), as per claim 1, further comprising a binding element (20) connected to the pulley or integral to the pulley, wherein there are two wires (21, 22) each having an end connected to the binding element. 5. The device (1), as per claim 4, wherein the pulley has a smoothed portion for fixing of said binding element (20) when said binding element is not integral to the pulley. 6. The device (1), as per claim 1, wherein said pulley comprises two throttles (21′, 22′) and one wire (21, 22) for each throttle. 7. The device (1), as per claim 1, wherein said biasing member is arranged to work under traction or under compression. 8. The device (1), as per claim 1, wherein, when the biasing member is configured as a compression spring. 9. A device (1), as per claim 1, wherein the first and the second septa are antagonist to one another due to two wires (21, 22), and wherein one of the two wire is fixed to the second septum (52) at one end and to the pulley (11) at an opposite end and the other one of the two wires is fixed to the first septum (30) at one end and to the pulley (11) at an opposite end. 10. The device (1), as per claim 1, wherein said first (2) and said second antagonist feeder conduits (3) are placed according to a divarication angle comprised between 10 degrees and 180 degrees. 11. The device (1), as per claim 1, wherein said first and said second antagonist feeder conduits are placed in an opposed position, according to a divarication angle of 180 degrees.
