ABSTRACT:
A stabilizer for a ventilation duct includes a sensor, sensitive to a variable parameter such as temperature, which affects the flow of air in the duct. The sensor includes an opening in a return flow conduit communicating with a deformable chamber contained within a section of the duct. As the parameter changes, pressure at the opening changes thereby affecting the volume of the chamber and likewise the volume of the section of the duct in which the chamber is located.
