ABSTRACT:
A novel multi-way valve is provided comprising an upper casing and a lower casing combined with the upper casing to form a fluid chamber therebetween, the lower casing having at least three outlet ports arranged in a predetermined angular spacing. A lower valve body is fixedly mounted on the bottom of the lower casing. The lower valve body has at least three passage holes coinciding with the corresponding outlet ports of the lower casing. An upper valve body comes into a fluid-tight, frictional contact with the lower valve body for rotational movement with respect thereto, the upper valve body having an arcuate slot which is selectively aligned with one or more of the passage holes of the lower valve body.
