Abstract
An inlet closure assembly includes a housing that defines an inlet configured to receive a fluid, such as airflow from the surrounding environment. The inlet closure assembly also includes a seal member that defines an inlet path in fluid communication with the inlet defined by the housing. The inlet closure assembly further includes a seat member configured to seat with respect to the seal member. The seat member is configured to obstruct the inlet path in its seated orientation. The inlet closure assembly also includes an actuation member configured to move the seat member into and out of seated engagement with the seal member. The inlet closure assembly further includes a biasing member for biasing the seat member into seated engagement with the seal member when the seat member is positioned to obstruct the inlet. The biasing member can be implemented using a magnet, a spring, and so forth.
