Abstract

Improvements introduced in an apparatus for controlling the air circulation in a duct, including a duct and air circulation control means comprising a control member for controlling the circulation of air through the duct, the duct member being movable. Control by an actuator comprising two rigid members, one of which is integral with or operatively connected to the control member and between whose members one or more extendable hollow bags are disposed, the or each bag having two opposite parts and a peripheral part of flexible thin material, each peripheral part having a negligible resistance to bending, the bags being arranged with their opposite parts in face-to-face contact and the two outermost opposite sides of the bags being in face-to-face contact with a respective one of the rigid members, means of entry being provided to allow the supply of air to each bag, the arrangement being such that when air is admitted into each bag, it extends to effect the movement of the movable rigid member, such being the maximum operating distance between the opposite portions of each bag that the contact area of the opposite portions of adjacent bags and each of the outermost opposing parts with their rigid member remains substantially unchanged between crushed and extended positions of the bags.
