Abstract

117,415. Rayner, G. H. T., and Rayner, P. Feb. 25, 1918 Addition to 116,660. Valve chests and casings.-Relates to improvements in fluid-operated tools of the kind described in the parent Specification, wherein the valve is provided with a projection on one side, or with a projection on one side longer than a projection on the other side, to ensure that, when the valve is turned, it works in a different part of the valve chamber bore. The valve chamber may have a renewable bushing as described in Specification 772/13, [Class 122 (ii), Steam-engine distributing and expansion valves &c.].
