Abstract:
1. An extraction module for extraction, under pressure, for the preparation of a beverage from a capsule containing a substance to be extracted, the extraction module comprising: extraction means comprising a first extraction sub-assembly comprising a base and a second extraction sub-assembly that can move against the first sub-assembly so as to form, in a closed position, an extraction chamber enclosing the capsule in a closure plane, and so as, in an open position, to maintain an opening space between the two sub-assemblies to allow the capsule to be inserted between the two sub-assemblies, a means for holding and positioning the capsule, the holding and positioning means capable of being pushed back linearly by the second movable sub-assembly, mounted coaxially relative to the second movable sub-assembly, displaceable linearly along the same axis as the second movable sub-assembly, and configured between the two sub-assemblies when the capsule is inserted so as to partially close the opening space to hold the capsule between the two sub-assemblies even when the module is in an inclined position; the holding and positioning means mounted around the base of the first sub-assembly so as to be capable of being pushed back into a retracted position for allowing the two sub-assemblies to close around the capsule, the holding and positioning means comprising a single component able to hold the capsule in a centered position in the opening space along several axis in the closure plane; and capsule ejection means for ejecting the capsule out of the module, wherein the holding and positioning means is locked, in the retracted position, when the extraction sub-assemblies are closed and is unlocked, in the holding position, only after the capsule has been ejected by the ejection means.
