Abstract

690,897. Non-return valves. HYMATIC ENGINEERING CO., Ltd. Feb. 11, 1952 [Feb. 26, 1951], No. 4588/51. Class 135 A non-return valve comprises inlet and outlet members 1, 2, respectively, secured together with a space between them and with the inlet and outlet passages leading into and from this space, and a diaphragm 9 provided with apertures 10 and placed between the two members in such manner that it is always flexed and, in the closed position, seats on that part of member 1 surrounding the inlet passage. The diaphragm is of fabric or rubber and its edge is located in the groove formed by a spacing washer 3 clamped between the members 1, 2. When opened by inlet pressure, the diaphragm is supported by an abutment 7 which is provided with a diametral groove or grooves leading to the outlet passage. In modifications, the inlet passage contains an apertured and domed disc, or there may be a plurality of inlet and outlet passages.
