    Abstract: An improved control valve for a reverse osmosis (RO) water purification system for supplying relatively pure water for on-demand dispensing, wherein the improved control valve positively terminates pure water production and brine outflow to a waste or drain when a pure water reservoir reaches a substantially filled condition. The control valve responds to a predetermined pressure differential between a tap or feed water inflow and produced pure water to close a pure water outflow line when the pure water reservoir reaches a substantially filled condition, thereby positively preventing further production of pure water. Shortly thereafter, the control valve closes a brine outflow line thereby positively preventing further water flow through the system until at least a predetermined volume of the reservoir-stored pure water is dispensed. When this occurs, the control valve re-opens in sequence the brine outflow and the pure water outflow lines.

  • Publication number: 20100108933
    Abstract: A fluid control valve comprises a valve element, a casing, a fluid flow passage formed in the casing, and an actuator drivingly moving the valve element to the casing in the axial direction. The fluid flow passage introduces a fluid from the inlet for the fluid and supplies the fluid into the clearance between the inner wall surface of a guide part and the outer peripheral surface of the valve element to lift the valve element relative to the inner wall surface of the guide part in the state of non-contact with each other. The actuator moves the valve element in the axial direction in the state of non-contact and changes the clearance between the outlet of the casing and the tip of the valve element to control the output flow amount or output pressure of the fluid.
