The technical problem of the present invention is to provide a machine for automatically preparing and dispensing beverages that has an infusion chamber of simple design and optimises the infusion of the capsule so that all areas of the latter are subjected to water injection. The solution of the invention is an assembly including a machine for automatically and dispensing beverages that comprises an infusion chamber (11) adapted for receiving a capsule (1) formed by a compacted aggregate of a substance to be infused trapped in an airtight and watertight conditioning envelope, said infusion chamber being provided with a member (12) for puncturing said conditioning envelope, penetrating into said aggregate of substance to be infused and injecting pressurized water into said capsule, said infusion chamber including a puncture area (20) adapted for locally puncturing or piercing said conditioning envelope, said puncture area (20) communicating with a device (21, 21a, 22) for recovering the liquid flowing through the punctured or pierced area of said conditioning envelope, characterized in that the puncture area (20) is located in the infusion chamber (11) on the same side as the puncturing member (12), said puncture area being provided at the base of said puncturing member and connected thereto, the water being injected towards the portion of the capsule (1) opposite said puncture area so as to be evenly distributed into the entire capsule.

1. A machine for the automatic preparation and dispensing of beverages, the machine comprising: an infusion chamber configured to receive a capsule formed by a compacted aggregate of a substance to be infused held in an air and water impermeable packaging envelope, the infusion chamber including a first side, and a second side opposite the first side, a cross-section of the second side defining an arc configured to be flush with a capsule having spherical shape;a projection for piercing the packaging envelope, to penetrate into the aggregate of a substance to be infused, and inject pressurized water into the capsule under a pressure of 5 to 20 bar; anda puncturing zone configured to act as a punch and weaken the packaging envelope at the time of placement of the capsule against the puncturing zone and, subsequently, to locally burst or pierce the packaging envelope as a result of injection of pressurized water into the capsule, the puncturing zone communicating with a device to recover the liquid flowing through the punctured or pierced part of the packaging envelope, characterized by the fact that the puncturing zone is arranged on the first side of the the infusion chamber and the piercing projection is arranged on the first side of the infusion chamber, the puncturing zone being arranged at the base of the piercing projection, joined to the latter, the water being injected into the part of the capsule opposed to the puncturing zone so that it can be uniformly distributed throughout the capsule, the puncturing zone including a first part having a first distance from the second side of the infusion chamber, and a second part having a second distance from the second side of the infusion chamber, the first distance being greater than the second distance, the puncturing zone defining a plurality of through-passages in the first part of the puncturing zone, the through-passages being in fluid communication with the device to recover the liquid. 2. A machine according to claim 1, wherein the puncturing zone constitutes a grill, and the second part of the puncturing zone includes molded needles. 3. A machine according to claim 2, wherein the through-passages have the shape of a cone frustum having a first width and a second width larger than the first width, the second width being downstream from the first width. 4. A machine according to claim 1, wherein the piercing projection comprises a needle adapted to pierce the packaging envelope of the capsule, the needle defining a water injection orifice in fluid communication with a conduit for pressurized water. 5. A machine according to claim 4, wherein the puncturing zone is arranged at the base of the needle. 6. A machine according to claim 4 wherein the puncturing zone is formed by a molded grill at the base of the needle. 7. A machine according to claim 6, wherein the through-passages have the shape of a cone frustum having a first width and a second width larger than the first width, the second width being downstream from the first width. 8. A machine according to claim 1, wherein the infusion chamber is formed by a front yoke and a rear yoke, the rear yoke being moveably mounted between a loading position enabling placement of the capsule in the infusion chamber and a closed position where the rear yoke is positioned with the front yoke so as to hold the capsule. 9. A machine according to claim 8 wherein the puncturing zone is arranged at the base of the needle and wherein the front yoke and the piercing projection are configured so as to form, behind the puncturing zone, a recovery chamber to enable recovery of the liquid flowing through the packaging envelope. 10. A machine according to claim 4 wherein the infusion chamber is formed by a front yoke and a rear yoke, the rear yoke being moveably mounted between a loading position enabling placement of the capsule in the infusion chamber and a closed position where the rear yoke is positioned with the front yoke so as to hold the capsule and wherein the front yoke and the piercing projection are arranged to be in a position enabling skewering the capsule on the needle and a position enabling the extraction of the capsule away from the needle. 11. A machine according to claim 1 wherein the piercing projection comprises a needle adapted to pierce the packaging envelope of the capsule, the needle defining a water injection orifice in fluid communication with a conduit for pressurized water and wherein the needle comprises a flange configured so that the pierced edges of the packaging envelope have been flattened above so as to be water impermeable under the effect of the pressure of the water injected into the capsule. 12. A machine according to claim 1, wherein the machine comprises a reservoir for storage of multiple capsules equipped with an opening enabling conveyance of the capsules to the infusion chamber. 13. A machine according claim 1, further including a conduit for evacuating the used capsules. 14. A machine according to claim 13 wherein the infusion chamber is formed by a front yoke and a rear yoke, the rear yoke being moveably mounted between a loading position enabling placement of the capsule in the infusion chamber and a closed position where the rear yoke is positioned with the front yoke so as to hold the capsule and wherein a closure element is arranged with the conduit to evacuate the infused capsules, the closing element being moveably mounted between a closed position shutting access to the conduit and an open position allowing access to the conduit, the movement of the closure element being synchronized with the movement of the rear yoke. 15. A machine according to claim 1 further including a yoke configured to move the capsule into the piercing projection, thereby causing the piercing projection to skewer the capsule. 16. A machine according to claim 1 further including a yoke configured to move the capsule into the piercing projection, thereby causing the piercing projection to skewer the capsule, the piercing projection being in a fixed position relative to the infusion chamber when the yoke moves the capsule into the piercing projection.
