Abstract

1456322 Valves LES PRODUITS ASSOCIES LPA SA 3 June 1974 [20 July 1973] 24442/74 Heading F2V A dispensing nozzle for buccal washing adapted to be held and operated in one hand includes a valve comprising an inlet 2, an outlet 5 and a magnetizable closure member 7 normally spring-biased to the open position as shown in Fig. 1, but movable to the closed position by the displacement of an annular permanent magnet 13 towards the closure member such that the force of attraction between the two overcomes the bias of the spring. In such a way a quick opening and closing of the valve is obtained. The magnet is preferably of barium ferrite. A chamber 4 between inlet and outlet is provided with a floating piston 20 which absorbs any shocks which occur when the valve is closed. The valve closure member may be made of magnetic material and the magnet 13 replaced by a ring of magnetizable material. The nozzle 6 is detachable.
