Abstract
897,678. Valves. FRANKENSTEIN & SONS (MANCHESTER) Ltd., P. Nov. 29, 1960 [Oct. 22, 1959], No. 35767/59. Class 135. A non-return valve comprises an elastic element 21 of natural or synthetic rubber, having a closure portion 23 adapted to cooperate with a seat 27 in the valve body 10 and an integral mounting portion 22 moulded with the closure portion and connected to the latter in concentric but axially-offset relation by integral angularly-spaced bars which are curved or inclined in a circumferential direction and which, when the portion 22 is mounted in the body, normally maintain the closure portion in contact with the seat. The mounting portion is of T-shaped cross-section and is retained in the valve body by a ring 26 bonded thereto. As shown applied to an inflatable life raft, the valve body, of metal or hard plastics material, is clamped to the material 15 of the lift raft by a nut 16, a washer 19 and ribs 17 being provided to form a seal. Two identical valves may be used in a manually-operated pump to act as inlet and outlet valves.
