ABSTRACT:
A hot/cold water inlet and outlet structure for a ceramic core shaft of a single handled faucet has a valve housing, a switch valve set, a valve mount, an upper switch valve, a lower switch valve, and a sealing ring wherein the valve housing has a valve chamber disposed at the interior thereof for the switch valve set and the valve mount thereof to be adapted therein respectively. The upper switch valve has a regulating recess defined at the bottom thereof; the lower switch valve includes a pair of arc hot/cold water inlet holes and a water outlet hole with indented groove seats defined thereon, correspondingly matched to arc hot/cold water inlet passages and a water outlet passage with higher protruded walls of the valve mount thereof; whereby, the lower switch valve is overlapped on top of the valve mount with the indented groove seats thereof securely joined to the higher protruded walls thereof in sealing engagement, further pressing downwards the sealing ring adapted at the valve mount therein to effectively prevent the leakage of water in use and ensure the precise engagement of the lower switch valve with the valve mount thereof.
