Abstract

842,105. Valves. HOPKINSONS Ltd., BROWN, R. L., and WOOFFINDIN, F. Oct. 14, 1957 [Nov. 26, 1956], No. 36047/56. Class 135. A butterfly valve closure 2, which is opened and closed by rotation about a diameter, is axially displaced in the direction of the arrow to bring it into sealing engagement with the convergent portion 6 of a U-shaped flexible projection 5 integral with a ring 4 bolted to the valve body 1.
