Abstract

756,162. Non-return valves. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 16, 1954 [Aug. 18, 1953], No. 22789/53. Class 135. A non-return valve comprises a non-resilient obturating member cooperating, in the closed position, with a fixed, resilient seating in such manner that the latter is non-yieldingly enclosed except for that part of its surface upon which the obturating member seats. The obturating member shown comprises a cylinder 16 with an intermediate partition carrying a depending tail 28 by which the valve can be manually opened against the pressure of its loading spring 31. The lower end of the cylinder seats, in the closed position, on a ring 15 of resilient material which is enclosed by the inner surface of the valve casing 11, a flange on the lower end of a liner 19, and a flanged cylindrical guide 26 for the tail 28 of the obturating member. When the valve is opened by fluid pressure applied at the lower end of the casing, the fluid flows through the annular space between the tail 28 and the cylindrical guide 26, through radial passages 29 in the guide, through passages 24 in the outer surface of obturator 16, and so to the outlet at the upper end of the casing. If the passages 29 are omitted, flow through the valve takes place when the obturating member clears the upper end of guide 26.
