A capsule used in the production of a beverage, includes an actuation element that is displaced by an actuation force. The actuation element is configured with a section of passageway and controls the moments of entry and exit of a pressurized flow through the capsule. The actuation element includes a flow accumulation chamber provided on a side of the zone facing the flow downstream, and at least one flow exit passage for discharge of the flow out of the accumulation chamber and of the capsule, at least in part as a result of flow accumulation in the flow accumulation chamber.

1. A capsule comprising: at least one construction element defining a zone of the capsule facing the flow upstream and a zone of the capsule facing the flow downstream in opposition to each other,an actuation element extending along at least part of the distance between said zones facing the flow up
1. A capsule comprising: at least one construction element defining a zone of the capsule facing the flow upstream and a zone of the capsule facing the flow downstream in opposition to each other,an actuation element extending along at least part of the distance between said zones facing the flow upstream and downstream, the actuation element including two element parts that engage at least temporarily with each other, the actuation element retained in a movable manner in said construction element by means of the two element parts each in a respective element fixture respectively provided in said zones facing the flow upstream and downstream,wherein at least one of the two element parts includes and/or defines together with their respective element fixtures, a flow accumulation chamber provided on the side of the zone facing the flow downstream, andwherein the actuation element includes and/or defines together with said element fixtures, at least one flow exit passage for discharge of the flow out of said accumulation chamber and of the capsule, wherein one of the at least one of the two element parts blocks the at least one flow exit passage in said respective element fixture, and as a result of a predetermined flow accumulation inside the flow accumulation chamber, the actuation element is caused to move to a position wherein the element part unblocks the at least one flow exit passage. 2. The capsule according to claim 1, wherein the actuation element carries out at least two successive displacements, in each case as a result of applying a certain actuation force, in each case resulting in at least one flow passage for entry of the flow inside the capsule, and at least one flow passage for discharge of the flow out of the capsule, respectively. 3. The capsule according to claim 1, wherein, as a result of the displacement of the actuation element, at least one flow passage is released for entry of the flow inside the accumulation chamber. 4. The capsule according to claim 1, wherein the actuation element and/or the element fixtures are provided with a plurality of passageways and/or with at least one permeable material, and the at least one flow exit passage through the accumulation chamber is provided when said passageways in the actuation element and/or in the element fixtures, are in each case unobstructed or are in substantial fluid communication with each other. 5. The capsule according to claim 1, wherein the element parts of the actuation element are configured so as move in isolation one relative to the other, along at least part of the distance between the zone of flow upstream and the zone of flow downstream. 6. The capsule according to claim 1, wherein a total displacement of the actuation element and/or a volume of the accumulation chamber are previously defined as a function of at least one type of aromatic substance, or of a dimension of a grain of said substance or of an interior volume of the capsule. 7. The capsule according to claim 1, wherein the configuration of at least one of the flow passages of entry inside the accumulation chamber and exit out of the capsule, including the form, the dimension and the distribution of respective passageways, is previously defined as a function at least of a type of aromatic substance, or of a dimension of a grain of said aromatic substance, or of an interior volume of the capsule. 8. The capsule according to claim 1, wherein a plurality of flow passages are disposed successively along the prevailing flow direction, whereby respective passageways are provided radially in a substantially uniform manner relative to a central symmetry axis of the capsule. 9. The capsule according to claim 1, wherein the two element parts of the actuation element are provided so that at least one may move at least partially along the other, or at least one may move along at least part of a respective element fixture, at least along the prevailing flow direction. 10. The capsule according to claim 1, wherein the extension of the element part on the side of the zone facing the flow upstream, is previously defined as a function at least of a type of aromatic substance, or an average dimension of a grain of the aromatic substance, or an interior volume of the capsule. 11. A device for using a capsule, the capsule comprising at least one construction element that defines a zone facing the flow upstream and a zone facing the flow downstream disposed in opposition to each other, and presenting an actuation element extending along at least part of the distance between said zones facing the flow upstream and downstream, and retained in a movable manner by means of two element parts that engage at least temporarily with each other, each in a respective element fixture provided in said zones facing the flow upstream and downstream, wherein the actuation element includes and/or defines together with said element fixtures, a flow accumulation chamber provided on the side of the zone facing the flow downstream, andthe actuation element includes and/or defines together with said element fixtures, at least one flow exit passage for discharge of the flow out of said accumulation chamber and of the capsule, wherein one of the at least two element parts blocks the at least one flow exit passage in said respective element fixture, and as a result of a predetermined flow accumulation inside the flow accumulation chamber, the actuation element is caused to move to a position wherein the element part unblocks the at least one flow exit passage, andwherein the device comprises at least one extraction chamber and is configured to:introduce the capsule in the extraction chamber,fix said capsule by mechanical clamping in said extraction chamber to exert a first actuation force (F1) upon the actuation element at least on the side of the zone facing the flow upstream so as to displace the actuation element,inject a fluid flow under a previously defined pressure and during a period of time, to exert a second actuation force (F2) upon the actuation element at least on the side of the zone facing the flow upstream so as to displace the actuation element so as to provide a flow passage out of the capsule.
