Abstract

L'invention concerne une pompe à membrane présentant une chambre de refoulement (9) séparée d'une chambre hydraulique (8) par une membrane (1), la chambre de refoulement (9) étant reliée respectivement à un raccord d'aspiration et à un raccord de pression et la chambre hydraulique (8), qui peut être remplie d'un fluide de travail (8), pouvant être soumise à une pression de fluide de travail pulsée. En outre, la chambre hydraulique (8) est reliée à un réservoir de fluide de travail (15) par l'intermédiaire d'une soupape de compensation de fuite (6) qui présente un corps de fermeture pouvant être animé d'un mouvement de va-et-vient entre une position de fermeture dans laquelle le passage de la soupape est fermé, et une position d'ouverture dans laquelle le passage de la soupape est ouvert, ledit corps de fermeture étant maintenu dans la position fermée à l'aide d'un élément de pression. L'élément de pression est configuré de telle sorte que, lorsque la pression dans la chambre hydraulique (8) est inférieure à une pression de réglage pL, le corps de fermeture (16) se déplace en direction de la position d'ouverture. L'invention vise à munir une pompe à membrane d'une soupape de compensation de fuite de manière à réduire les inconvénients de l'état de la technique, voire à les supprimer. A cet effet, l'importance de la masse du corps de fermeture (16) est telle que le corps de fermeture (16) ne se déplace pas sur plus de 0,2 mm dans la direction de la position d'ouverture, dans le cas d'une chute de pression à 0 bar ne durant pas plus de 1 milliseconde en raison d'un à-coup de pression dans la chambre hydraulique (8)
