Abstract
An active air intake adapted for selectively regulating fluid flow into an engine generally includes a housing defining an opening, a covering member disposed relative to the opening and translatable between opened and closed conditions, an actuator including an active material element operable to effect movement of the member, a load limit protector configured to present a secondary output path for the element, an overheat protection mechanism for preventing unintentional activation and stress loads in the element, a biasing mechanism for returning the member to the original condition, and a latching mechanism for retaining the member in the closed condition.
