초록 ▼

A water purification device includes a housing having a base portion and a generally-cylindrical cup-shaped cap removably secured thereto. An input fluid channel in the base portion communicates with one end of the chamber defined by the cup and an outlet fluid channel communicates with that chamber end. A filter cartridge disposed within the cap has a conduit that extends between its opposite end walls. Filter material surrounds the conduit. An inlet opening in the cartridge is positioned to communicate with the input fluid channel so as to permit water to flow through the filter material. An outlet opening in the cartridge is arranged to communicate from the filter material to the other end of the aforementioned conduit remote from said outlet channel. The conduit other end is positioned to communicate to the outlet channel. A valve is included in an extension of the base portion in order selectively to control the distribution of water as between an outlet passage and the inlet channel. The valve itself has a bore and corresponding stem which are longitudinally tapered, a recess cut longitudinally into the stem for permitting fluid to flow from an inlet port outwardly from one end of the stem, an inset cut laterally into the stem opposite the aforesaid recess, and a resilient sealing member disposed in a groove cut laterally into the stem and surrounding the inset exclusive of the recess.

A water purification device comprising: a housing having a base portion and a generally-cylindrical cup-shaped cap removably secured to said base portion, said base portion including an input fluid channel communicating with one end of the chamber defined by said cap and an outlet fluid channel communicating with said one end of said chamber; a generally cylindrical filter cartridge disposed within said gap and having a conduit extending between its opposing end walls, said cartridge including a purification material contained in surrounding relationship to said conduit and having an inlet opening positioned to communicate from said input channel to said material and an outlet opening arranged to communicate from said material to the end of said conduit remote from said outlet channel with the other end of said conduit being positioned to communicate with said outlet channel; a control portion projecting laterally from said base portion with said control portion including an inlet coupling attachable to a source of water supply, an outlet passage, and valve means for selectively controlling the distribution of water between said outlet passage and said inlet channel; and said valve means further including: a body having a bore the diameter of which tapers longitudinally: means defining inlet and outlet ports in respectively space-opposed portions of said body; a valve stem sized and tapered longitudinally to be received within said bore; a recess cut longitudinally into said stem for permitting fluid to flow from said inlet port Outwardly from one end of said stem when said recess is aligned with said inlet port; an inset cut into said stem in a position generally opposite said recess and in alignment between said ports; a groove cut laterally into said stem and surrounding said inset exclusive of said recess; and a resilient sealing member disposed in and throughout said groove to block fluid flow to said recess, while permitting fluid flow between said port, when said inset is aligned between said ports. As useful in a water purification device for diverting water either through a filter medium or directly in by-pass thereof, a valve assembly comprising: a body having a bore the diameter of which tapers longitudinally; means defining inlet and outlet ports in respectively space-opposed portions of the sidewall of said body; a valve stem sized and tapered longitudinally to be received within said bore; a recess cut longitudinally into said stem for permitting fluid to flow from said inlet port outwardly from said one end of said stem when said recess is aligned with said inlet port; an inset cut into said stem in a position generally opposite said recess and in alignment between said ports; a groove cut laterally into said stem and surrounding said inset exclusive of said recess; a resilient sealing member disposed in and throughout said groove to block fluid flow to said recess, while permitting fluid flow between said ports, when said inset is aligned between said ports; and the region of said bore in the vicinity of said inlet port being untapered so as to preclude presentation to said sealing member of a sharp edge between said bore and said inlet port.
