(FR) SOUPAPE ET DIAPHRAGME POUR UNE POMPE
Abstract: front page image
(EN)A diaphragm pump (10) having a pump body (11) providing opposing pump chambers (12, 13). Mounted in the body is a piston assembly (14) having pistons (15) joined by a piston rod (16). Each piston (15) is sealingly connected to the body (11) by means of a diaphragm (22) so that each of the chambers (12, 13) is divided into a first a a second sub-chamber, with the flow of fluid being pumped is governed by a pair of valves (30).

Un ensemble piston (14) est monté dans le corps et comprend des pistons (15) joints par une tige de piston (16). Chaque piston (15) est relié de façon étanche au corps (11) au moyen d'un diaphragme (22) de telle sorte que chacune des chambres (12, 13) soit divisée en une première et une seconde chambre secondaire, le flux de fluide pompé étant contrôlé par une paire de soupapes (30). Chaque soupape (30) comprend une base (31) à laquelle un élément de soupape mobile (35) est fixé de manière mobile.
