Abstract
1,196,459. Valves. ETABS. A. GUIOT. 1 Aug., 1967 [9 Feb., 1967], No. 35241/67. Heading F2V. Check valve, particularly for a liquid motor fuel diaphragm pump, comprises a flexible diaphragm 5, e.g. of natural or synthetic rubber, which obturates an opening 4 in a seat 1, and is biased by a coil spring 14 clamped by its centre coil against the diaphragm. The spring is prestressed and as shown engages the diaphragm along at least two annular zones one on each side radially of the seat opening. In a modification, a washer (22), Fig. 4 (not shown), is interposed between the spring and the diaphragm over the area radially inwardly of the seat opening.
