Zusammenfassung:An improved variable volume control assembly for conditioned air systems having an improved air flow amplifying measuring means that amplifies the difference between the total pressure and the static pressure and is sensitive at low pressures, an improved air flow collector-straightener, a critical ratio of the area of the inlet to the area of the expansion chamber, and a vortex filter strategically located within the assembly for maximum reduction of turbulence and noise.
