Patent ID: 7562618

Claim:
Extraction module for extraction, under pressure, for the preparation of a beverage from a capsule containing a substance to be extracted, 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 planel; and capsule ejection means for ejecting the capsule out of the module, the ejection means elastically tensioned through contact with at least one elastic tensioning element forming part of the holding and positioning means and tensioned when the two extraction sub-assemblies are closed and freed from their elastic tension to cause ejection when the two sub-assemblies are reopened.
