Abstract

1363035 Cistern discharge valves CARRARA & MATTA SpA 15 Sept 1972 [18 Nov 1971] 42993/72 Heading E1C [Also in Division F2] A cistern discharge valve, of the kind wherein a tubular column 9 provides an overflow passage communicating directly with a discharge conduit 2 and carries at its lower end an annular valve disc (11, Fig. 3, not shown) above which is fitted an annular body 10 of buoyant material, the valve disc normally sealing a discharge opening and being lifted therefrom by operation of a manually-actuated lever 13, is modified by the provision of a dashpot device comprising a flexible membrane 14 which is secured to the top of the column and fitted sealingly around the periphery of a cap member 16 to form an air chamber which communicates with the atmosphere via a ballcheck valve 19, 20 and also via a calibrated aperture in a member 18. When the column 9 is raised air is expelled rapidly through the valve 19, 20, whereas lowering of the column can only take, place slowly as air enters via the aperture.
