ABSTRACT:
Pressurized control signal apparatus is disclosed, which being supplied with air from a source of variable pressure, is operative to produce a control signal essentially independent of variations in the supply pressure. In one aspect of the invention, the control signal is amplified in volume of flow; in another, it is generated in response to temperature. The apparatus is specifically adapted to effect regulation of air flow in a variable air volume (VAV) temperature conditioning system in response to temperature in a conditioned zone, wherein the supply air for the apparatus is derived from a temperature conditioned air distribution duct of the VAV system.
