Abstract

727,366. Elastic valves. VEREINIGTE ARMATUREN-GES. May 15, 1953 [May 16, 1952; July 25, 1952; July 25, 1952], No 13667/53. Class 135. In valves of the kind having a sleeve-like resilient diaphragm arranged to coact with a streamlined core to close an annular passage through the valve, the diaphragm, on its inner and outer surfaces, is formed with staggered longitudinal slits or recesses permitting it to fold bellows-fashion in the circumferential direction to facilitate radial expansion and contraction. The adjacent edges of the slits or recesses are pressed together when the valve is closed. In Fig. 1 the diaphragm c is fixed at one end i and the free end g coacts with a wear-resistant seat ring f on the core e, d to function as a check valve. The longitudinal slits or recesses h may extend to the free end of diaphragm or terminate short of it as shown. The valve shown in Fig. 7 embodies a diaphragm clamped at each end il, i2 and urged towards the core by hydraulic pressure admitted through a port o. Ports p opening to the hollow interor of the downstream part d of the core may remain open when the diaphragm first engages the core but are progressively closed as the pressure admitted through the port o is increased.
