Abstract

668,325. Valves. MEREVALE ENGINEERING CO., Ltd., and ALLISON, A. June 2, 1950 [July 8, 1949], No. 18082/49. Class 135. A non-return valve comprises a casing c with an outlet d and an inlet surrounded by a corrugated perforate screen e, and a closure member a having a hollow head and a weighted stem i whereby the centre of gravity of the member is below the head. The member coacts with a rubber etc. seat g, having grooves g<SP>1</SP> which permit the seat to swell without distorting, and opening movement is limited by fins c<SP>1</SP> on the casing. In a modification, movement of the closure member is limited by projections on the stem, and the seat is positioned in the casing by a clamping ring. A dashpot may be connected to the stem i.
