Patent attributes
A multiport rotary disc valve includes a valve housing having chamber walls that segregate an internal space of the housing into subchambers that each provide a portion of a fluid path through the valve housing. The valve includes a diverter assembly disposed in a cylindrical first subchamber, the diverter assembly controlling fluid flow through the valve housing. A second subchamber is disposed radially outward with respect to the first subchamber. In some rotational orientations of the diverter assembly, a fluid path between valve ports of the valve housing includes a first path portion that is disposed in the first subchamber and extends axially through the diverter assembly and a second path portion that is disposed in the second subchamber. The valve also includes seal assemblies disposed in housing so as to be aligned with the diverter assembly along a rotational axis of the diverter assembly.
