Abstract

1,157,573. Valves. J. B. RATELBAND. 10 Oct., 1966, No. 45216/66. Heading F2V. The sleeve-like diaphragm 3 of a check valve is connected by ribs 6 to a part 7 of a core of the valve, the part 7 being made from the same elastic material as the diaphragm with a spherical recess 10 to receive a stud 9 on a metal or plastic part 8 of the core. The outer edge of the diaphragm together with a plastic or metal ring 5 is clamped between parts 1 and 2 of the casing.
