Abstract: The present disclosure provides a system for sealing a compartment. The system includes a door with a seal positioned on a bottom surface of the door. The system also includes one or more hinges coupled to the door. The door rotates from a closed position to an open position via the one or more hinges. A height of the door with respect to a floor surface increases in response to a rotation of the door from the closed position to the open position due to a helical slope of both a first cam surface of the one or more hinges and a second cam surface of the one or more hinges. The seal transitions from a compressed state to a relaxed state in response to the rotation of the door from the closed position to the open position.

Abstract: The present disclosure provides system for sealing a refrigerated galley of an aircraft. The system includes a door, and a seal assembly positioned at a bottom surface of the door. The seal assembly includes (i) a housing coupled to the bottom surface of the door, (ii) a seal positioned at least partially in the housing, wherein the seal is moveable relative to the housing and the door, (iii) a biasing mechanism coupled to the housing and the seal and configured to hold the seal in a relaxed state by applying a biasing force to the seal in a direction away from a floor surface of the refrigerated galley, and (iv) an activation mechanism coupled to the housing. The activation mechanism is configured to transition the seal from the relaxed state to a compressed state in response to a rotation of the door from an open position to a closed position.
