Zusammenfassung:A multi-port valve having a longitudinal axis and a solenoid coil wound about a bobbin. Coaxially aligned with the longitudinal axis is an armature, at least partially disposed within the bobbin. The armature is coupled to a valve member that forms a sealing relationship with at least one valve orifice. A two-piece can having a first can component and a second component that cooperate to define an interior region. The solenoid coil, bobbin, pole piece, and at least part of the armature are disposed in the interior region of the two-piece can. The second can component is adjustably threaded to the first can component such that a longitudinal dimension of the interior region of the two-piece can may be adjusted to vary the size of a gap between the pole piece and the armature.
