Abstract
1,192,150. Valves. A. G. WILD & CO. Ltd. 25 Oct., 1968, No. 50812/68. Heading F2V. A valve controlling the supply of fluid to and from a pit prop comprises inlet and exhaust valve members 15, 16 biased to closed positions by a common spring 21. Inlet pressure unseats the valve member 15 and fluid flows to the prop via 24. The pressure is released by inserting the head of a face cam 27 into recess 32 such that, upon rotation of the head by handle 28, cam surface 29 co-operates with pad 33 to cause nose 30 to unseat valve member 16. Each valve member consists of a ball 19 bonded by adhesive to an enlarged head of a stub spindle 17. An inlet filter 26 is fitted and prop pressure is detected at 23.
