Title (EN) CHECK VALVE
(FR) CLAPET
Abstract: front page image
(EN)A check valve that opens at very low flow rates and still handles rather large flows. The check valve has a membrane mounted on a displaceable piston biased towards a valve seat formed as a plate with holes. At low flow rates the membrane flexes away from the seat. At larger flow rates the piston on which the membrane is mounted, is displaced away from the valve seat by. The check valve is suitable for liquid circuits in which very different flow rates arise.
(FR)L'invention concerne un clapet qui s'ouvre à des débits très faibles tout en gérant des écoulements relativement importants. Ce clapet présente une membrane montée sur un piston mobile sollicité vers un siège de clapet servant de plaque perforée. A de faibles débits, seule la membrane s'incurve et s'éloigne du siège tandis que sous l'effet de débits plus importants, c'est aussi le piston, sur lequel est montée la membrane, qui s'éloigne du siège de clapet. Le clapet convient aux circuits de liquides dans lesquels les débits subissent de fortes variations.
