    摘要： A filter apparatus for a home reverse osmosis water system is provided. The apparatus has a head, which has a forward flow inlet port for connection to a reverse osmosis water unit, and which has a reverse flow outlet port for connection to a water service faucet. The apparatus also has a cartridge, which has a twist-on securing means for connection to the head, a filter assembly for filtering forward fluid flow and for filtering reverse fluid flow, and a combination inlet and outlet port for connection to a pressurized water tank. The filter assembly has a primary filter unit, which is disposed in a cartridge primary chamber, and a secondary filter unit, which is disposed in a cartridge secondary chamber, and a valve means, e.g., check valve, which is disposed between the primary chamber and the secondary chamber, whereby forward fluid flow is permitted to flow through the primary filter unit and also through the secondary filter unit, and reverse fluid flow is only permitted to flow through the secondary filter unit.The foregoing apparatus enables permeate from a reverse osmosis module to pass through the filtration cartridge, first through the primary and then the secondary filter unit, and after storage of the filtrate therefrom, passing the stored filtrate through the secondary filter unit of the filtration cartridge in a reverse direction to the direction the permeate passed through the unit, to filter the water just prior to use.

    摘要翻译： 提供一种家用反渗透水系统的过滤装置。 该设备具有头部，其具有用于连接到反渗透水单元的正向流入口，并且具有用于连接到水服务水龙头的反流出口。 该设备还具有一个盒，其具有用于连接到头部的扭转固定装置，用于过滤正向流体流并用于过滤反向流体流的过滤器组件，以及用于连接到加压水箱的组合入口和出口 。 过滤器组件具有设置在盒主室中的初级过滤器单元和设置在盒二次室中的次级过滤器单元和设置在主室之间的阀装置，例如止回阀 和次级室，由此允许正向流体流动通过初级过滤器单元并且还通过次级过滤器单元，并且仅允许反向流体流动流过二级过滤器单元。 上述装置使得来自反渗透模块的渗透物首先通过主过滤器和次级过滤器单元，并且在将滤液保存在其中之后，将储存的滤液通过过滤筒的二次过滤器单元 与渗透物通过该单元的方向相反的方向，以便在使用之前对水进行过滤。

    摘要： A filtering device includes a head intended to be permanently installed in a fluid dispensing machine and a disposable canister therefor. A central chamber is formed in the head which chamber is in communication with an inlet port and an outlet port for receiving an unfiltered liquid and supplying a filtered liquid, respectively. The disposable canister has a flask shaped main body with a flat top and a neck of substantially uniform diameter on the top. The neck fits in the central chamber. A tube extending through the neck defines an annular clearance between the tube and the interior of the neck which annular clearance is in fluid communication with the inlet port. The opening into the tube located at the top of the neck is in fluid communication with the outlet port in the head. A pair of tab receptacle on the head and a complementary pair of tabs on the canister are engageable with one another by 1/4 rotation of the canister to lock the canister to the head.
