摘要： Apparatus for preparing beverages such as coffee or tea, comprising a filter unit (3), an extraction chamber (1) positioned above said filter unit, and a reception chamber (2) positioned underneath the filter unit, which reception chamber at the bottom part thereof comprises a discharge channel (9) for discharging the prepared beverage. The apparatus comprises furthermore means for supplying coffee or tea powder (7) and hot water (6) in the extraction chamber to prepare an extract during a predetermined extraction period, and a control unit (13) controlling the various components such that after activating said means for supplying predetermined amounts of hot water and coffee or tea powder in the extraction chamber (1), an extraction period is measured during which the extraction process is completed, after which the pump (11) is activated to suction the prepared extract through the filter paper web (3). The pump unit (11) is double acting and is connected through suitable piping (12) to the side wall of the reception chamber (2) at a level above the maximum fluid level in said reception chamber. A discharge valve (10) is installed in the bottom of the reception chamber (2) or in said discharge channel (9). The control unit (13) is embodied such that during the extraction period the discharge valve (10) will be closed and the pump unit (11) will be activated to press air into the reception chamber (2) causing such an overpressure that an air stream is created through the filter unit (3) and through the mixture of water and coffee or tea powder agitating said mixture and that at the end of the extraction period, still with closed discharge valve (10), the action of the pump (11) unit is reversed to suction air from the reception chamber (2) causing such an underpressure that the prepared extract will be suctioned through the filter unit (3) into the reception chamber (2).

摘要： A decoction device for an extraction apparatus, in particular for preparing espresso, comprises a decoction chamber (7) enclosed by a chamber wall (5) for receiving a quantity of powder therein. The decoction chamber is situated between a first chamber bottom (20) and a second chamber bottom (30). The first chamber bottom (20) is coupled to a linear actuator and is axially movable in the decoction chamber so as to compress the powder to a bed. A drive is provided to impose a relative rotation between one of the chamber bottoms and the chamber wall as the chamber bottoms (20,30) approach each other. The respective chamber bottom (30) is for this purpose rotatable within the chamber wall (5) and the drive is able and configured to impose a rotation thereon during an approach movement of the first chamber bottom (20). A slip coupling (60) is provided in the transmission.

摘要： The invention relates to an apparatus for brewing a drink, such as coffee. The apparatus comprises a chamber (3) for accommodating a mixture of water and a ground product, such as coffee, to be extracted, the chamber having a perforated base (2) on which a strip of filter material (8) can be laid. Means (14,26) are fitted on one side of said base for moving the strip of filter material over the base after a quantity of drink has been brewed and has been removed via the piece of filter material. The means for moving the strip of filter material comprise a separate transport unit (14), and fixing means (28,29) are provided for fixing the transport unit to one of two opposing sides of the base, as desired. The means for moving the strip of filter material can also comprise a separate guide unit (26), which is fixed in each case to that side of the base which is opposite to the side where the transport unit (14) is located. A supply unit (19) for filter material can also be fitted at the side of the base where the guide unit (26) is located. A winding unit (34) for used filter material is optionally fitted at the side of the base where the transport unit (14) is located.
摘要翻译： 本发明涉及一种用于冲泡诸如咖啡的饮料的设备。 该设备包括用于容纳待抽出的水和诸如咖啡的研磨产品的混合物的腔室（3），该腔室具有可在其上放置过滤材料条（8）的穿孔基座（2）。 装置（14,26）安装在所述基座的一侧上，用于在一定量的饮料已经被冲泡并且已经通过一片过滤材料被移除之后将过滤材料带移动到基座上。 用于移动过滤材料带的装置包括独立的运输单元（14），并且提供固定装置（28,29）以根据需要将运输单元固定到基座的两个相对侧中的一个。 用于移动过滤材料带的装置还可以包括单独的引导单元（26），该单独的引导单元（26）分别固定在基座的与运输单元（14）所处的侧相对的那侧。 用于过滤材料的供应单元（19）也可以安装在导向单元（26）所在的基座的侧面。 用于过滤材料的卷绕单元（34）可选地安装在运输单元（14）所在的基座的侧面。

摘要： Appareil pour la préparation de boissons, par exemple café ou thé. Il se compose d'un élément de filtre (3), et de deux compartiments d'extraction (1) et de réception (2) situés respectivement au-dessus et au-dessous dudit élément. Le compartiment de réception comprend un canal d'évacuation (9) par où s'écoule la boisson préparée. L'appareil comprend en outre un système qui permet d'approvisionner le compartiment d'extraction en café ou thé en poudre (7) et en eau chaude (6), et de préparer un extrait en un laps de temps prédéterminé. Il inclut aussi un élément de contrôle (13) de ces divers composants: ainsi, une fois actionné le système qui fournit des quantités prédéterminées d'eau chaude et de thé ou de café en poudre dans le compartiment d'extraction (1), l'appareil mesure un temps d'extraction pendant lequel ce processus est mené à bien, après quoi la pompe (11) se met en marche pour aspirer au moyen de la bande de papier filtre (3) l'extrait ainsi préparé. La pompe (11) à double action est reliée par des canalisations (12) à la paroi latérale du compartiment de réception (2) à univeau supérieur au niveau maximal de liquide dans ledit compartiment. Une soupape de sortie (10) est installée au fond du compartiment de réception (2) ou dans ledit canal d'évacuation (9). L'élément de contrôle (13) est conçu de telle sorte que, pendant le temps d'extraction, la soupape de sortie (10) reste fermée et que la pompe (11) soit actionnée pour refouler l'air dans le compartiment de réception (2). Ainsi, il se crée une surpression telle qu'une veine d'air passe à travers l'élément de filtre (3) et le mélange d'eau et de café ou de thé en poudre. L'air vient agiter ce mélange et à la fin du temps d'extraction, la soupape de sortie (10) restant toujours fermée, la marche de la pompe (11) s'inverse pour aspirer l'air en provenance du compartiment de réception (2). Il en résulte alors une compression telle que l'extrait préparé est aspiré par le filtre (3) dans le compartiment de réception (2).
