Abstract

L'invention concerne une pompe à membrane comprenant une chambre de refoulement, un raccord de pression et un raccord d'aspiration, lesdits raccords de pression et d'aspiration étant reliés à la chambre de refoulement, une chambre hydraulique, la chambre de refoulement et la chambre hydraulique étant séparées l'une de l'autre par une membrane. La chambre hydraulique peut être remplie avec un fluide de travail et être sollicitée par une pression de liquide de travail pulsée, ce qui a pour effet de faire passer la membrane, d'une première position dans laquelle la chambre de refoulement présente un volume plus réduit, à une seconde position dans laquelle ladite chambre de refoulement présente un volume plus important. La chambre hydraulique est reliée à un réservoir de liquide de travail par l'intermédiaire d'une soupape de complément de remplissage en cas de fuites. La membrane comporte un élément ressort présentant une première constante de ressort, ledit élément ressort étant conçu de sorte à exercer une première force prédéterminée sur la membrane en direction de la seconde position. L'invention vise à mettre au point une pompe à membrane et un procédé pour ajuster une telle pompe, qui permettent de réduire voire de résoudre entièrement les problèmes évoqués. A cet effet, selon l'invention, l'élément ressort peut être remplacé par un autre élément ressort, conçu de manière à exercer une seconde force prédéterminée sur la membrane en direction de la seconde position ou bien la force que l'élément ressort exerce sur la membrane en direction de la seconde position peut être ajustée.
