ABSTRACT:
"A water purification system has a reverse osmosis filtration unit which receives feed water from a feed water valve and separates it into product water and waste water. A reservoir has a movable separator dividing it into a product water chamber for receiving the product water and a control water chamber. The product water is delivered to an outlet connection from the product water chamber or directly from the filtration unit. A regulator is connected to the waste water outlet port of the filtration unit, the control water port of the reservoir, and a drain line. The regulator has a first valve for providing waste water from the filtration unit to the control water port of the reservoir for urging the separator toward the product water chamber. The regulator has a second valve that can rapidly drain water from the control water chamber of the reservoir and rapidly reduce pressure in the control water chamber, thus facilitating the refilling of the product water chamber. A relief valve downstream of the second valve maintains a low pressure in the system to avoid undesirable cycling of the system between high pressure and low pressure."
