Abstract
An infusion group for machines for the dispensing of beverages in the form of infusion is disclosed. The infusion group has a capsule-holder configured to receive a capsule for the preparation of an infusion beverage, a dispensing head adapted to cooperate with the capsule-holder to form a chamber for the infusion of the capsule. The dispensing head has a dispensing channel, a perforation disc and an associated supporting member mounted on the dispensing head. The dispensing head also has a discharge channel upstream of the dispensing channel. The configuration of the dispensing head is such that the discharge channel is closed when the perforation disc and the supporting member are in the dispensing position and open when they are in the rest position.
Claims21
An infusion group for machines for the dispensing of beverages in the form of infusion, said infusion group comprising:
- i) a capsule-holder configured to receive a capsule (C) for the preparation of a beverage in the form of an infusion,
- ii) a dispensing head adapted to cooperate with said capsule-holder to form a chamber for the infusion of said capsule (C), said dispensing head comprising a dispensing channel,
- a perforation disc and a supporting member associated with said perforation disc, said supporting member being mounted in said dispensing head, and:
- said dispensing head also comprises a discharge channel, said discharge channel being arranged upstream of said dispensing channel with respect to a longitudinal direction (L) along which a beverage is dispensed, said discharge channel being arranged downstream of said perforation disc with respect to said longitudinal direction,
- the perforation disc and the supporting member are movable relative to the dispensing head between a dispensing position and a rest position, wherein the perforation disc and the supporting member are slidably housed in the longitudinal direction in a cavity formed in the dispensing head, wherein the inlet of the discharge channel is formed in the cavity between the perforation disc and the dispensing channel,
- the configuration of the dispensing head being such that the discharge channel is closed when the perforation disc and the supporting member are in the dispensing position and open when they are in the rest position.
An infusion group for machines for the dispensing of beverages in the form of infusion, said infusion group comprising:
- i) a capsule-holder configured to receive a capsule (C) for the preparation of a beverage in the form of an infusion,
- ii) a dispensing head adapted to cooperate with said capsule-holder to form a chamber for the infusion of said capsule (C), said dispensing head comprising a dispensing channel,
- iii) a perforation disc and a supporting member associated with said perforation disc, said supporting member being mounted in said dispensing head, and
- said dispensing head also comprises a discharge channel, said discharge channel being arranged upstream of said dispensing channel with respect to a longitudinal direction (L) along which a beverage is dispensed, said discharge channel being arranged downstream of said perforation disc with respect to said longitudinal direction,
- the perforation disc and its supporting member are movable relative to the dispensing head between a dispensing position and a rest position, wherein the perforation disc and its supporting member are slidably housed in the longitudinal direction in a cavity formed in the dispensing head, wherein the inlet of the discharge channel is formed in the cavity between the perforation disc and the dispensing channel,
- the configuration of the dispensing head being such that the discharge channel is closed when the perforation disc and the supporting member are in the dispensing position and open when they are in the rest position,
- wherein the capsule-holder comprises a hollow body that protrudes therefrom in the longitudinal direction towards the infusion head, said hollow body being slidably fitted in a cavity formed in the infusion head wherein the outlet of a conduit for the supply of an infusion liquid is arranged,
- and wherein a sealing element is slidably fitted inside the hollow body, said sealing element being urged by resilient means against the opening of the hollow body facing the infusion head, said resilient means being configured to yield in the longitudinal direction beyond a predetermined pressure threshold so as to allow passage of a flow of infusion liquid.
