Abstract

348,752. Vacuum valves ; components. MUIR, A., 194, Oldham Road, Ashton-under-Lyne. March 6, 1930, No. 7329. [Class 135.] Rotary disc valves.-In a vacuum service conduit system a disc valve A, B is provided having a tapered socket attachment B2 to facilitate connection or disconnection of the system to or from a flexible extension D and approximately simultaneous operation of the valve. The valve comprises two portions A, B having co-operating bores f, e and flanges A1, Bl connected and hinged together by a screw C and spring washer a. Stops G, H limit the relative rotary sliding movement of the members A, B in the fully open and closed. positions of the valve. One or both of the connections A2, B2 may be formed as a spigot-and-socket connection. The vacuum in the bore f assists in holding the flanges A1, Bl tightly together.
