System of water purification and product distribution

Claim 1

A system of water purification and product distribution comprising, in combination with a water service line, a hollow vessel having an inlet communicating with said water service line and also having a pair of outlets including a product outlet and a drain outlet, a cylinder fixedly secured within said vessel; said cylinder having an inlet port communicating with the inlet of said vessel and also having an outlet port, a reservoir supported within said vessel and in communication with said product outlet of said vessel, a reverse osmosis module mounted for reciprocation within said cylinder; said module having an inlet in communication with said water service line through said outlet port of said cylinder and also having a pair of outlets including a product outlet in communication with said reservoir and a drain outlet for repetitively delivering nearly pure product water through said product outlet thereof to said reservoir and for delivering separated out impurities through said drain outlet thereof to said drain outlet of said vessel, upon the downward movement of said module into said cylinder to close said outlet port of said cylinder and thereby shut off supply of raw water from said water supply line, a valve controlled drain line establishing communication between said drain outlet of said vessel and said drain outlet of said module for creating back pressure therein, and a valve-controlled product dispensing line in communication with said reservoir through said product outlet of said vessel,; depletion of the supply of nearly pure product water in said reservoir by opening said dispensing line reducing the hydraulic pressure above said module and increasing hydraulic pressure below the same to effect upward movement of said outlet port of said cylinder to open said outlet port of said cylinder and said inlet of said module thereby causing flow of raw water into said module and the refilling of said reservoir with nearly pure product water from said module.

Claim 2

A system of water purification and product distribution comprising, in combination with a water service line, a hollow vessel having an inlet communicating with said water service line and also having a pair of outlets including a product outlet and a drain outlet, a cylinder fixedly secured within said vessel; said cylinder having an inlet port communicating with the inlet of said vessel and also having an outlet port, a reservoir supported within said vessel and in communication with said product outlet of said vessel, a reverse osmosis module mounted for reciprocation within said cylinder; said module having an inlet in communication with said water service line through said outlet port of said cylinder and also having a pair of outlets including a product outlet in communication with said reservoir and a drain outlet for repetitively delivering nearly pure product water through said product outlet thereof to said reservoir and for delivering separated out impurities through said drain outlet thereof to said drain outlet of said vessel, upon the downward movement of said module into said cylinder to close said outlet port of said cylinder and thereby shut off supply of raw water from said water supply line, a valve controlled drain line establishing communication between said drain outlet of said vessel and said drain outlet of said module for creating back pressure therein, and a valve-controlled product dispensing line in communication with said reservoir through said product outlet of said vessel,; depletion of the supply of nearly pure product water in said reservoir by opening said dispensing line reducing the hydraulic pressure above said module and increasing hydraulic pressure below the same to effect upward movement of said outlet port of said cylinder to open said outlet port of said cylinder and said inlet of said module thereby causing flow of raw water into said module and the refilling of said reservoir with nearly pure product water from said module.
