Abstract

L'invention concerne une variante de la pompe hydraulique à diaphragme selon le brevet principal. Cette pompe comporte une membrane anti-pulsations dont une face est disposée en regard de l'ajutage de refoulement et dont l'autre face est soumise à la pression de la chambre d'admission et est sollicitée en direction dudit ajutage par un poussoir soumis à l'action d'un organe élastique tel qu'un ressort, et l'admission du fluide dans la chambre d'admission s'effectue par l'intermédiaire d'un orifice formant siège pour un clapet d'obturation muni d'un organe de rappel. Le clapet et le poussoir sont disposés de façon telle que l'orifice et l'ajutage de refoulement soient obturés simultanément lorsque la pompe est à l'arrêt et qu'un organe de commande dudit clapet soit sollicité par le poussoir en vue de provoquer l'ouverture dudit orifice lorsque la pompe fonctionne.
