Abstract

L'invention concerne un ensemble d'infusion à pression variable d'une machine à café, comprenant un premier sous-ensemble (1) et un second sous-ensemble (2) formant la chambre d'infusion (3), un mécanisme d'entraînement entraînant ledit premier sous-ensemble (1) de manière à ouvrir et à fermer ladite chambre d'infusion (3), ainsi qu'une soupape régulatrice de pression (5). Cette soupape régulatrice de pression (5) comporte une première ouverture de couplage (50) reliée à la chambre d'infusion (3), une seconde ouverture de couplage (51) reliée au chauffe-eau de la machine à café, une ouverture de couplage de régulation de pression (52), ainsiqu'une tige de soupape (53) reliant ladite première ouverture de couplage (50) à ladite ouverture de couplage de régulation de pression (52) à l'état initial. Un bloc de retenue (101) est monté sur ledit premier sous-ensemble (1). La tige de soupape (53) est enfoncée par le bloc de retenue (101) durant la période de fermeture de ladite chambre d'infusion (3), de sorte que la première ouverture de couplage (50) soit reliée à la seconde ouverture de couplage (51) et ne soit plus reliée à l'ouverture de couplage de régulation de pression (52).
