A safety device including a valve comprising a valve disk mounted on a rotatable shaft and movable axially toward and away from a valve seat. The shaft is rotatable by means of a geared transmission driven by a turbine wheel which is rotated by water flowing through the device. The pressure of water flowing through the device urges the valve disk toward the valve seat, but the disk and seat do not engage until the disk has rotated through a predetermined angle corresponding to a predetermined volume of water flow through the device.

A safety device to regulate the volume of water flow to a washing machine, comprising a valve which is normally open, characterized in that said valve comprises a rotating disk firmly fitted to a small control shaft which is axially slidable against the action of a helical spring and formed by a plate with a first and a second hub portion in front of and behind the plate, respectively, in that the first hub portion is provided with at least one frontal tooth intended to engage, for pre-established angular position of the plate, the corresponding notch of a location appendage which is integrally formed with the device body, and the second hub portion presents an adjustment surface suitable to cooperate with the corresponding surface of a fixed stop cap when the small shaft and the shutter are pushed to the rest position by the action of said helical spring; and that the tooth and the adjustment surface are angularly displaced with respect to the notch of the location appendage of the same angle.
