Abstract
A multiport valve has a plurality of inlets and outlets with selected positions to selectively direct fluid differently through the valve based on the position of the valve. A cylindrical exterior stemshell rotates internal to a housing to position channels and/or bores to provide the desired flow paths. Some flow paths are channels which extend linearly from one port to another, whether formed into an exterior surface, parallel to an axis of rotation of the stemshell, or pass from an inlet to an outlet in the exterior surface of the stemshell, preferably separated from flow from flow to an internal passage, which is preferably colinear with the axis of rotation, for at least some embodiments.
