Abstract
A multiport valve has a stemshell rotatable within a valve body with two columns of ports arranged in a planar array. An extra port extends external to the array and inlet ports communicate with selected outlet ports. The stemshell has lateral channels and longitudinal channels which cooperate with the ports at selected angular positions to provide desired inlet/outlet flows while preventing intermixing within the valve.
