Abstract
Device for the extraction of coffee, includes an extraction chamber supplied by the vertical introduction of tablets or premeasured small quantities of ground coffee. The extraction chamber includes two movable portions for horizontal movement so as to move toward or away from each other, one of the movable portions including a hot water inlet, the other having a coffee extract outlet. The movable portions are each mounted on an eccentric shaft adapted to transmit to them oscillatory movements of opposite directions. A braked pivotal connection between each eccentric shaft and each movable portion, combines a horizontal movement and an oscillatory movement for sequencing the phases of opening and closing the extraction chamber. The device is useful in coffee machines of the espresso type usable with tablets or premeasured small quantities.
