ABSTRACT:
There is provided a tap water purifier to be directly coupled to a faucet pipe, which includes a water purifying barel filled with a filter medium and a cylindrical valve body integral with the purifying barrel. The purifying barrel having opposite opening ends. The valve body is inserted in a cylindrical bore formed in a casing for rotation about the longitudinal axis of the valve body. The casing has tap water inlet port means, tap water outlet port means and purified water outlet port means formed therein, the tap water inlet port means and the purified water outlet port means opening to the cylindrical bore in the casing at an angular distance of 180.degree. from each other in the same axial position. The valve body includes first and second flow path means formed therein, the first flow path means being communicated with one opening end of the purifying barrel, the second flow path means being communicated with the other opening end of the purifying barrel. The first and second flow path means open to the peripheral surface of the valve body at an angular distance of 180.degree. from each other in an axial position corresponding to the opening positions of the tap water inlet port means and the purified water outlet port means. The valve body also includes third flow path means formed therein and communicated with the tap water outlet port means. The third flow path means opens to the peripheral surface of the valve body in an angular position between the opening positions of the first and second flow path means and in the axial position corresponding to the opening position of the tap water inlet port means.
