Abstract
A seal assembly for a multi-port valve assembly, the seal assembly including a plurality of beads integrally formed as part of a rotor, at least one seal element in sliding contact with one or more of the beads, and at least one lip seal integrally formed as part of the seal element. One or more of the beads applies force to the seal element, such that the force is transferred to the lip seal. The beads include at least one circumferential bead which circumscribes the rotor, and the circumferential bead continuously applies force to the seal element when the rotor is in each of a plurality of orientations. The beads also include at least one tangential bead extending along an outer surface of the rotor, and the tangential bead applies force to the seal element when the rotor is in one of a plurality of orientations.
