Abstract: A system for controlling airflow in a plenum, that comprises a worm gear and planetary gear that are removably coupled to a worm shaft and planetary shaft, respectively. The planetary shaft controls the movement of a damper between an open position permitting maximum airflow through the plenum, and a closed position restricting airflow through the plenum. A motor or gear-motor is positioned at the plenum for driving the worm shaft. The motor is controlled by a remotely located controller that includes a power supply for operating the motor and that has a display providing a continuous indication of the position of the damper between the open and closed positions. The controller is connected to the motor through a cable with a detachable electrical connection between the cable and the controller, such as a jack and plug. A wall plate for housing the electrical connection is mounted on a wall or other structure.

Abstract: A ventilation module for a vehicle having a housing including a flap hingedly secured along an inner edge to the housing to extend across its open interior. The flap includes side edges and an interconnecting outer edge which contact, in a closed flap condition, support locations configured along the housing to define its open interior. One or more fingers extend from at least one of the side and outer edges of the flap so that the fingers abut standoff locations of the housing located in proximity to the support locations. Upon a sufficient positive air pressure condition created within the passenger compartment which overcomes a holding force exerted by the fingers against said stand-offs, the flap is allowed to open in a controlled fashion to vent to the exterior the excess air pressure, until reclosing upon achieving an air equilibrium condition.
