ABSTRACT:
There is provided a self-regulating nozzle for a liquid supply line. The nozzle comprises a nozzle body attachable to the line, a vortex chamber within the body and a vortex producing inlet means through which the liquid in the line enters the vortex chamber. One wall of the vortex chamber is constituted by the surface of a stretchable diaphragm, the opposite wall of the chamber is provided with an aperture leading to the consumer and the other surface of the diaphragm is exposed to line pressure. The arrangement is such that the vortex produced by the inlet means results in the creation of a low pressure zone on the surface of the diaphragm which is exposed to the vortex chamber and the effective cross section of the aperture is controlled by the stretching of the stretchable diaphragm.
