ABSTRACT:
A water system uses a pressure reservoir of extremely small size. A valve device is placed between a water pump and the pressure reservoir. The valve device has a constant outlet pressure to limit the flow from the pump at high pressures. The pump is turned on and off by a pressure on/off switch. The valve device maintains the pressure to the reservoir at or below the on switch pressure except for a dribble flow. The dribble flow fills the reservoir when there is little or no water usage from the reservoir. The dribble flow is achieved by a notch in the valve surfaces of the valve device. Each time the valve opens any debris in the notch is washed from the notch thereby keeping the notch free of debris.
