Abstract: L'invention concerne un régulateur de pression pour une cartouche d'encre, qui est monté de manière amovible sur la cartouche d'encre (1), et comprend une partie couverture et une partie compartiment (8) qui forme un compartiment étanche avec la partie couverture, et un mécanisme de soupape pour réguler la pression dans le compartiment étanche. Le mécanisme de soupape comprend une chambre de soupape (83), une entrée d'encre (81) permettant l'entrée d'encre dans le mécanisme à soupape, un siège de soupape (84) comprenant au moins un orifice de soupape (841), et un élément soupape (85) fermant ou libérant sélectivement l'orifice de soupape en fonction de la variation de pression des deux côtés de celui-ci. La sortie d'encre est placée à un emplacement où se situe le point le plus haut du compartiment de soupape dans le sens de la pesanteur. On assure ainsi que l'encre ne s'écoule pas avant que l'ensemble du mécanisme de soupape ne soit rempli d'encre. Un interstice éventuel entre l'élément de soupape et le siège de soupape dû à une erreur de fabrication peut être obturé par la tension superficielle du liquide, qui supprime toute communication entre les deux faces de l'élément de soupape et crée une différence de pression entre elles. Ainsi, la pression interne de la cartouche d'encre est régulée de manière stable, et les fuites d'encre sont évitées.
