Abstract

1,060,977. Valves. H. MœLLER, E. MœLLER, and R. MœLLER, [trading as HELIOSAPPARATEBAU KOMM.-GES. MœLLER & CO.]. April 9, 1964 [April 10, 1963], No. 14736/64. Heading F2V. The individual slats 1, shown in partial cross - section, of a Venetian blind - type shutter normally hang vertically so that the lower edge (not shown) of each slat makes contact with the upper edge 3 of an adjacent slat, and the area of each slat below the pivotal axis 2 is greater than that above the axis so that air flow from a fan or blower striking the slats in the direction of the arrow 8 swings the slats to an open position. To minimize the pressure drop caused by the slats, which may be made of a plastics material, the upper portion of each slat is bent over as shown to enclose the pivot spindle 2 and a metal bar 6 to make the upper portion heavier than the lower portion so that the centre of gravity is brought to the point 7 where it exercises a small closing moment when the slat is closed and a smaller closing moment when the slat is open or horizontal. The bent-over portion may alternatively be shaped to accommodate round-section bars, or the upper part of the slat may be made wholly of metal and attached to the lower part, of plastics material, by a tongue and groove joint.
