ABSTRACT:
A flow control device includes a resilient member defining an opening through which fluid flows, the opening becoming smaller upon increase of pressure of fluid supplied thereto, and relatively larger upon decrease of pressure of fluid supplied thereto. A check valve allows flow of such fluid in an irrigating direction through the device upon a certain level of pressure of supplied water being achieved, but closes when such pressure falls below such certain level to block flow through the device.
