Abstract

1,146,683. Valves. R. L. HESSE. 11 March, 1966 [15 March, 1965; 21 April, 1965], Nos. 10911/65 and 16833/65. Heading F2V. [Also in Division AS] A resilient valve element for use in a breathing valve 1 having mutually opposed inlet and outlet conduits 3, 5 terminating in mutually opposed spaced seats, comprises (see Figs. 1 and 2) a resiliently expandable hood 10 the open end of which is adapted to be sealingly attached around a seat 3a of an inlet and which has a top portion adapted, upon expansion of the hood, to come into sealing contact with a seat 5a of a mutually opposed outlet, at least one port 12 being provided in the wall of the hood outwardly of said top portion, the or each port being adapted to be open in the expanded state of the hood and to be closed in the relaxed state of the hood. In a modification (see Figs. 3, 4a and 4b) the valve element 50 is made of two members, a flat membrane 51 and a funnelshaped membrane 52 attached along restricted portions 53, 54 of their circumferences-the non-attached parts of the circumferences forming labial ports.
