ABSTRACT:
A pressure regulated water supply system having an accumulator arranged between an input line supplied by a pump and an output line leading to the consumers. A diaphragm between the input line and the accumulator controls a pressure switch which turns the feed pump on and off. The diaphragm is provided with an opening of a size, relative to the delivery flow of water to the pump, such that a pressure difference occurs across it. A check valve is arranged on the side of the diaphragm facing the accumulator above the passage opening and the diaphragm itself forms the seat for the check valve. The mouth of a duct located above the surface of the diaphragm connects to the pressure switch. The distance between the mouth and the surface of the diaphragm is chosen so that, if the diaphragm is deflected due to a pressure difference, it rests against the mouth and closes it.
