ABSTRACT:
The inlet to the water valve is provided with a resilient flow control device which deflects under pressure to reduce the inlet orifice and maintain substantially uniform flow. On the outlet side of the flow control the liquid is forced to turn at right angles to reach the multiple restricted orifices where the liquid again must turn 90.degree.. At low pressures the flow is divided between 8 orifices 4 of which are gradually shut off by deflection of the flow control so at high inlet pressure the flow is divided among 4 orifices positioned in channels protecting them from being shut off by deflection of the flow control. The reduced velocity caused by the two 90.degree. turns in flow results in substantial reduction of flow noise.
