Abstract

706,941. Ventilator valves. AIR CONTROL INSTALLATIONS, Ltd., and WRIGHT, F. Oct. 24, 1952 [Oct. 24, 1951], No. 24895/51. Class 137. [Also in Group XXIX] An apparatus for controlling fluid flow, eg. air through a ventilating duct 10 has one or more blades 14-16 free of twist and secured obliquely to one side of a rotatable shaft 11, and others 14a-16a secured obliquely in the opposite sense on the other side. Thus in one position the blades are edge on to the flow and offer little resistance, while the 90 degrees rotation of the blades gives a maximum restriction to flow and a maximum rotational swirl to the fluid. Pairs of blades may be formed from one sheet of metal partly slit across its width, the two portions being bent in opposite directions and secured to arms 17 radiating from the shaft.
