Abstract

851,732. Valves. METROPOLITAN - VICKERS ELECTRICAL CO. Ltd. July 7, 1958 [July 15, 1957], No. 22369/57. Class 135. A gate - type vacuum - control valve, which comprises a closure plate 3 for controlling a bore 2 through valve body parts 4, 5, is sealed in the closed position relative to the latter by inflating a pair of tubes, each positioned between a different one of the parts 4, 5 and the plate 3. The tubes, which may be of rubber or similar material, are deflated prior to moving the plate to the open or closed position. One tube may be dispensed with.
