Abstract
Disclosed is a multi-way valve comprising a valve casing having a fluid inlet and a plurality of fluid outlets, first and second chambers defined in the valve casing, a partition disposed between the first and second chambers and having a plurality of fluid paths, a plurality of valve elements each engaging a corresponding fluid path from the first chamber side for opening and closing the fluid path and a driving device having cams which selectively drive the valve elements from the second chamber side. The multi-way valve can be manufactured as a small-sized one, and therefore, a water purifier using the valve also can be assembled as a small-sized one as a whole. The amount of resident fluid in the valve can be decreased, thereby improving the hygienic property of the water purifier. The operation for taking off or exchanging valve elements can be simplified.
