<p>1,167,379. Valves. C.B. ASSOCIATES Ltd. 8 March, 1968 [7 April, 1967], No. 16116/67. Heading F2V. [Also in Division F1] A valve which, when subjected to impact, tilting or vibration will serve to interrupt the flow of fluid, such as internal combustion engine fuel, between an inlet 9 and outlet 10, includes a guided shuttle 7 one end of which carries a frusto-conical projection 8 which is adapted to co-operate with a seat formed in the flow passage, and the other end of which is adapted to be engaged by a magnetic material ball 4 when the force of attraction between the latter and a magnet 2 is broken, such engagement resulting in the shuttle moving bodily until the projection 8 becomes seated. The closed state of the valve is subsequently maintained by means of springs 6 which engage the end portion of the shuttle until the valve is reset by manual depression of a plunger 12. In an alternative construction, not shown, the valve may be arranged to be opened by impact or the like.</p> |
