摘要： 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.
