Title
(EN) COFFEE MACHINE INFUSION GROUP
(FR) GROUPE D'INFUSION DE MACHINE À CAFÉ
Abstract
(EN)
The coffee machine infusion group comprises a closure piston (3) and an infusion cylinder (4) subjectable to a reversible roto-translation movement between a position of engagement with the closure piston (3) for the creation of an infusion chamber and a position of disengagement from the closure piston (3) for the loading of a coffee powder load, the infusion group having an expulsion system of the spent coffee powder load from the infusion chamber, the expulsion system comprising an expulsion piston (29) displaceably housed in the infusion cylinder (4), the expulsion system having mechanical driving means adapted for an interference with the expulsion piston (29), occurring due to the rotational component of the roto-translation movement, for displacement of the expulsion piston (29) relative to the infusion cylinder (4 ).
(FR)
L'invention porte sur un groupe d'infusion de machine à café qui comprend un piston de fermeture (3) et un cylindre d'infusion (4) pouvant être soumis à un mouvement de roto-translation réversible entre une position d'engagement avec le piston de fermeture (3) pour créer une chambre d'infusion et une position de dégagement par rapport au piston de fermeture (3) pour charger une charge de poudre de café. Le groupe d'infusion comporte un système d'expulsion de la charge de poudre de café usagée hors de la chambre d'infusion. Le système d'expulsion comprend un piston d'expulsion (29) reçu de façon à pouvoir être déplacé dans le cylindre d'infusion (4) et des moyens d'actionnement mécaniques conçus pour interférer avec le piston d'expulsion (29), ce qui se produit du fait de la composante de rotation du mouvement de roto-translation, et déplacer le piston d'expulsion (29) par rapport au cylindre d'infusion (4).
