Abstract

676,479. Double-beat valves. HYMATIC ENGINEERING CO., Ltd. Feb. 20, 1951 [April 21, 1950], No. 9844/50. Class 135. A valve closure member comprises valve heads a, b of equal diameter slidable on an actuating stem c leakage along which is prevented by packing rings d. The head b abuts a shoulder i on the stem and Belleville washers, e, f, are interposed between the heads. A nut j is threaded on the stem to compress the washers and space the heads so that they engage seats m on the valve body simultaneously. The seating surface k of each head may be of rubber.
