Abstract

848,871. Valves. NAPIER & SON Ltd., D. Dec. 13, 1956 [Dec. 13, 1955], No. 35808/55. Class 135. A valve member 2 slidable in a casing 1 to control flow between an annular inlet port 5, connected to a supply line 4 and a permanently open annular outlet port 6, 4, comprises spaced lands 8, 9 separated by a portion which gradually decreases in diameter from the inlet land 8 to a minimum diameter at 11 and then increases in diameter in a smooth curve 13 up to the land 9 to provide gradual opening and closing of the inlet port 5 to reduce instability.
