The water purifier is operated entirely automatically and hydraulically in response to the opening and closing of the outlet valve from which pure water is drawn. All of the passageways and control valves are contained within a unitary body so that there are no external hoses and fittings. The only connections to the body are a pure water outlet, a waste water outlet and the water inlet. In the filter chamber a reverse-osmosis filter membrane is circumscribed by a brine seal at the same end portion as where the pure water is discharged. All water passageway connections are made at that end of the filter chamber, so that the other end can be unthreaded for removal and replacement of the filter membrane without disconnecting water lines. An improved pilot valve within the unit has a tapered end portion engaging an O-ring seat held in place by a spring-pressed washer. The unit also includes a fast-acting check valve, with a floating valve member connected to the periphery of the valve chamber by a plurality of flexible strips.

A water purifier comprising a filter chamber, a reverse-osmosis filter membrane in said filter chamber, said reverse-osmosis filter membrane having a cylindrical exterior surface, a tank, movable means in said tank dividing said tank into two chambers of variable volume, the first of said chambers being adapted to receive pure water, the second of said chambers being adapted to receive unpurified water, a water inlet adapted for connection to a source of tap water under pressure, a first water passageway for conducting tap water from said inlet to said filter chamber so that a portion thereof can be purified by passing through said reverse-osmosis filter membrane, and another portion can remain unpurified, a first water outlet adapted for connection to a pure water line having a valve therein for tansmission to a location of consumption, a second water passageway for conducting pure water from said filter chamber to said first chamber of said tank, and from said first chamber of said tank to said first water outlet, a second water outlet, a third water passageway for conducting unpurified water from said filter chamber to said second outlet, and to said second chamber of said tank for forcing purified water out of said first chamber of said tank to said first water outlet, control valve means for controlling the flow of tap water in said first water passageway, the flow of pure water in said second water passageway, and the flow of unpurified water in said third water passageway, control passageway means connected to said second water passageway for transmitting the pressure in said second water passageway to said control valve means for effecting automatic operation thereof entirely in response to the pressure of said pure water, said filter chamber including a first part fixed relative to said tank and defining one end portion of said filter chamber, and a second part rotatably coupled to said first part for permitting separation of said second part from said first part for removal and replacement of said reverse-osmosis filter membrane, one end of said reverse-osmosis filter membrane being received in said first part and the opposite end of said reverse-osmosis filter membrane being received in said second part, such that a portion of the circumference of said reverse-osmosis filter is exposed upon such separation of said second part from said first part, for facilitating removal and replacement of said reverse-osmosis filter membrane, said reverse-osmosis filter membrane having an axially projecting outlet at said one end thereof for discharging pure water therefrom, said first part of said filter chamber including a tubular section receiving said projecting outlet of said reverse-osmosis filter membrane, whereby pure water is discharged into said tubular section, said second water passageway being connected to said tubular section for receiving pure water therefrom, said third water passageway being connected to said first part of said filter chamber outside of said tubular section for receiving unpurified water, said first water passageway being connected to said first part of said filter chamber at a location relative to said one end of said filter membrane which is axially inward of said connection of said third water passageway to said first part, and an annular seal around said reverse-osmosis filter membrane and engaging the wall of said first part of said filter chamber, said annular seal being between said connection of said third water passageway and said connection of said first water passageway to said first part of said filter chamber for separating the same.
