Claim 0:
1. A system for controlling airflow from a galley compartment to an air extraction system plenum chamber comprising:
an actuating assembly comprising:
a cylinder;
a heat-expanding material disposed within the cylinder;
a piston disposed within the cylinder, wherein the heat-expanding material is configured to actuate the piston when the heat-expanding material is heated;
a piston seal; and
a return spring seated at one end at the piston and its opposite end at a retaining surface proximate to an open face of the cylinder, wherein a compressive force of the spring upon the piston at least partially counteracts the force of the heat-expanding material on the piston; and
a valve assembly coupled to the actuating assembly and disposed upon at least one of a surface of the galley compartment or a face of the plenum chamber, wherein an adjustment of the valve by the actuating assembly adjusts airflow within an opening of at least one of the galley compartment or the plenum chamber.
