Device, for automatically closing valves used for filling reservoirs such as toilet cisterns, includes float movable along end part that is pivotally coupled via rod to vertical stand

摘要

The closure device is for a valve of the type that opens by movement of a movable piece (6) and closes under the action of a float (9) that pushed back the movable piece to an initial position upon rising water level. During a final filling phase, a vertical stand (13), via its lower end (21), blocks the rising course of the float so that simultaneously, the lower end (7) of the movable piece contacts the upper face (8) of the float. The upper part (14) of the stand (13) pivots about a horizontal pin (15), and a rod (16) is fixed to the upper part, so that an end part (17) is parallel to the stand. The float is fixed to the end part and is movable along the length of the end part.
