Abstract: The invention relates to a brewing unit (01) for a beverage preparation apparatus for substrate portions, in particular for a coffee machine for pre-portioned coffee units, having a support (09) and a brewing chamber which has at least two brewing chamber halves (02, 32), which are movable relative to one another in a first direction (08), and has a drive device (28), by means of which at least one brewing chamber half (02) can be moved relative to the support (09) such that the brewing chamber halves (02, 32) can be transferred at least into an open position and a closed position, and a separate locking mechanism for locking the brewing chamber halves (02, 32) in a closed position. According to the invention, the locking mechanism comprises four locking elements (03).

Abstract: The invention relates to a brewing unit (01) for a beverage preparation device for substrate portions, in particular for a coffee machine for pre-portioned coffee units, the brewing unit (01) having a support (04) and a brewing chamber (11) having at least two brewing-chamber halves (02, 03) configured to move relative to each other in a first direction (03.1), and preferably a mechanical drive for moving the brewing-chamber halves (02, 03) between an open position, in which the brewing-chamber halves (02, 03) are spaced apart from each other, and a closed position, in which the brewing-chamber halves (02, 03) are in contact with each other in the area of contact surfaces (09, 10), in particular by moving one brewing-chamber half (03) relative to the support (04).

Abstract: The invention relates to a brewing unit (01) for a beverage preparation device for substrate portions, including a carrier (04) and a brewing chamber (11), which has at least two brewing chamber halves (02, 03), which are movable relative to one another in a first direction (03.

Abstract: The present invention relates to a brewing apparatus (1) for making a beverage from a single-serve capsule (2), wherein the brewing apparatus (1) has a first brewing-chamber element (3), a second brewing-chamber element (4) and a sealing device (5), wherein the first brewing-chamber element (3) can be moved along a central axis (12) between a loading position, in which the first and the second brewing-chamber elements (3, 4) are spaced apart from one another, and an operating position, in which the first and the second brewing-chamber elements (3, 4) have been moved towards one another to form a substantially closed brewing chamber (10), wherein, in the operating position, the sealing device (5) is arranged between the first and the second brewing-chamber elements (3, 4), wherein the first or second brewing-chamber element (3, 4) has a liquid-feeding device (6) for injecting liquid into a single-serve capsule (2) located in the brewing chamber (10).
