Abstract

A controlling mechanism for a three-way valve includes a transmission axis movably received in the valve and having first teeth formed on a free end thereof. A rotation axis is movable and intermittently rotatable in the valve and having second teeth integrally formed on the rotation axis to correspond to the first teeth. A spring is received inside the valve to provide a recoil force to the rotation axis to maintain the second teeth of the rotation axis to be in contact with the first teeth of the transmission axis so that movement of the transmission drives the rotation axis to move and rotate simultaneously for selectively blocking the inlet of the valve.
