Publication number: 20150167854Abstract: A ceramic valve with an intermediate section having cold water supply functions allows the driven slot to be set into an off-center position on the coupling seat. There is an active clearance between the driven slot and toggle end. A coupling seat and a biased rotary support unit arranged at an MT-center position on the inner seating, portion of the rotary driving seat are incorporated, so a biased rotary support position is shaped between the rotary driving and coupling seats. When the braking valve rod swings to an oblique water supply mode from the intermediate section, the toggle end will linearly toggle the driven slot, then the coupling seat and rotary valve block may rotarily shift by taking the biased rotary support unit as a pivot point, so the water flow control slot is only connected with the cold water through-hole in a cold water supply mode.Type: ApplicationFiled: December 16, 2013Publication date: June 18, 2015Applicant: KUCHING INTERNATIONAL LTD.Inventor: Mei-Li CHEN
