Abstract
1,095,247. Valves. SULZER BROTHERS Ltd. Nov. 28, 1966 [Dec. 31, 1965], No. 53094/66. Heading F2V. The pivoted flap check valve 2, 3 is loaded by a weight 10, there being an interposed spring 11 to prevent hammering. Lever 7 is fast with the flap. Lever 9 is frictionally mounted for damping. Lever 7 may be omitted and the spring 11 replaced by a torsion spring (22), Fig. 4 (not shown), or the rigid lever 9 may be replaced by a lever in the form of a double leaf spring (32, 33), Fig. 5 (not shown), of which one leaf (32) is secured to the other by a grip (36) to provide damping. In a modification for existing valves, a lever (40) bearing the weight is frictionally pivoted to an existing lever (40) and connected thereto by a spring (45), Figs. 6 and 7 (not shown). It is stated that in large valves the weight can be mounted on the disc with the resilient element, which may be of rubber, interposed.
