초록 ▼

A filter assembly is provided for a manifolded water filtration system and includes a filter element, a brine seal located at the top of the filter element and engaging a boss depending from the system manifold. The brine seal isolates a rinse water discharge port, communicating with a an outlet of the filter element, from an untreated water inlet port formed in the boss so as to ensure that the water to be treated passes through the filter membrane as opposed to directly out of the rinse water discharge port. This configuration eliminates the need for an exterior feed line, thus simplifying the system and preventing vibration during system start-up. The brine seal also structurally reenforces the filter element, facilitates assembly of the filter, increases the capacity of the assembly, and reduces the chances of failure and leakage.

대표청구항 ▼

A water filtration system comprising: A. a manifold having a rinse water discharge port formed therein; B. an annular boss extending downwardly from said manifold, said boss having outer peripheral threads and an internal passage formed therein through which untreated water flows and which terminates in an untreated water inlet port; C. an annular filter element having an upper end surrounded by said boss, communicating with said discharge port, and terminating in an upper axial surface; D. an annular fitting extending upwardly from said upper axial surface of said filter element; E. a filter housing which encases said filter element and which is enclosed except for an open upper axial surface; F. an internally threaded sump nut which fastens said filter housing to said boss; and G. a brine seal which isolates said inlet port from said rinse water discharge port, said brine seal including (1) a annular body having an inner peripheral surface which surrounds said upper axial end of said filter element and which has an outer peripheral surface, said annular body having a lower portion sealingly secured to said filter element and an upper portion extending above said upper axial surface of said filter element, (2) a ring which engages said annular fitting, (3) a plurality of ribs which extend radially from said ring to said inner peripheral surface of said annular body proximate a junction between said upper and lower portions thereof, said ribs engaging said upper axial surface of said filter element, and (4) a skirt which extends outwardly from said outer peripheral surface of said annular body proximate an upper end of said upper portion, which is angled downwardly, and which sealingly engages said boss.
