Abstract

1,141,198. Ventilators. WOODS OF COLCHESTER Ltd. 27 Feb., 1967 [4 March, 1966], No. 9561/66. Heading F4V. [Also in Division F1] A ventilation unit mounted on, a duct 28, Fig. 1, at an opening 2 through a wall or roof 3, comprises an impeller 4 (see Division F1), a resiliently mounted electric driving motor 5, a substantially square cowl 13 and four shutter vanes 15 which are opened automatically by the discharge flow against the actions of springs 24 and gravity. Some of the flow passes between each shutter vane and the cowl to prevent their contact and thereby shutter noise. The cowl, impeller and shutter vanes may be of plastics reinforced, for example, by glass fibre or metal. One or two electric driving motors may be arranged above or below the impeller. Two electric motors may be mounted directly on the impeller shaft or arranged at opposite sides thereof and connected thereto by belt drives, one of the two motors acting as a standby unit. In an alternative embodiment, Figs. 9 to 11 (not shown), each shutter vane is planar and ribbed, and the cowl is hinged about a horizontal axis to a plastics duct (28) so as to be pivotable to a position permitting access to the impeller. In another embodiment, Fig. 12 (not shown), the cowl is replaced by a horizontal square plate (37) above the impeller and a separate short tubular baffle (45) surrounding the impeller, and shutter vanes are pivoted at their lower ends, the arrangement being such that the discharge flows in an upward direction. In an air conditioning unit containing a filter, a number of impellers are arranged side by side each in a substantially bell-shaped cowl with its mouth opening upwardly to deflect the impeller discharge into an axial direction.
