ABSTRACT:
There is provided a cable tension regulator having a pivotable hub which is rigid with an operating lever. Two quadrants are pivotably mounted on the hub and have fixed on their peripheries respective cables for connection to a control or controlled element. Resilient means urge the quadrants to pivot in the direction corresponding to tensioning of the cables. Means are provided for locking the quadrants on the hub when an additional traction is exerted on one of the cables by the control element and for releasing the quadrants when the tensions of the two cables change simultaneously. Each quadrant is pivotably mounted on the hub by means of a disengageable one-way coupling which prevents, when in operation, the quadrant from pivoting under the effect of the resilient means. There is provided means for disengaging the one-way coupling when the respective cable is taut.
