Abstract
A control valve of a faucet includes a base, a lower ceramic block, an upper ceramic block, a coupling block, a bottom bushing, an inner barrel, a housing, and a control shaft. The control shaft has a lower end formed with a drive member rested on the inner wall of the inner barrel. The drive member of the control shaft has a peripheral wall formed with a plurality of flattened faces. Thus, the flattened faces of the drive member of the control shaft reduce the friction between the drive member of the control shaft and the inner wall of the inner barrel, so that the control shaft is operated easily and conveniently, thereby facilitating a user operating the faucet.
