A brewing apparatus for a coffee machine, in particular for domestic use, comprises a housing (10) which encloses a brewing chamber (19) and has a nozzle assembly (8, 9, 11) arranged on one side and a base (12) with an outflow (40) for the brewed fluid arranged on an opposite side, a sealing element
A brewing apparatus for a coffee machine, in particular for domestic use, comprises a housing (10) which encloses a brewing chamber (19) and has a nozzle assembly (8, 9, 11) arranged on one side and a base (12) with an outflow (40) for the brewed fluid arranged on an opposite side, a sealing element (20) being provided between the nozzle assembly (8, 9, 11) and housing (10). According to the invention, the sealing element (20) is retained on the nozzle assembly (8, 9, 11) such that it can be moved in the direction of the housing (10) and of the brewing chamber (19). Sealing can thus take place straightforwardly and, in addition, it is possible to configure the volume of the brewing chamber (19) in a variable manner via the sealing element (20).

What is claimed is: 1. A brewing apparatus for a coffee machine, in particular for domestic use, having a housing (10) which encloses a brewing chamber (19) and has a nozzle assembly (8, 9, 11) arranged on one side and a base (12) with an outflow (40) for the brewed fluid arranged on an opposite side, a sealing element (20) being provided between the nozzle assembly (8, 9, 11) and housing (10), the sealing element (20) being retained on the nozzle assembly (8, 9, 11) such that it can be moved in the direction of the housing (10) and of the brewing chamber (19), wherein the sealing element (20) has an outer section on which are formed sealing lips (22) which butt against a radially outwardly projecting flange (21) of the housing, and wherein the sealing element (20) has an inner section on which a further sealing lip (25) is provided for forming a sealing surface which butts against an annular section (26) of a holder (9) for the sealing element (20). 2. The brewing apparatus as claimed in claim 1, wherein the sealing element (20) can be positioned against the housing (10) for sealing purposes by way of an outer sealing surface (22) and can be moved in relation to the brewing chamber (19) by way of an inner part. 3. The brewing apparatus as claimed in claim 1, wherein the sealing element (20) can be subjected to pressure on the side which is directed away from the brewing chamber (19). 4. The brewing apparatus as claimed in claim 1, wherein the movement of the sealing element (20) takes place hydraulically, and there is a connection between a supply line (30) for the nozzle assembly (8, 9, 11) and a pressure chamber (27) for the sealing element (20). 5. The brewing apparatus as claimed in claim 4, wherein a supply line (30) for the nozzle assembly (8, 9, 11) is closed by a prestressed valve (31). 6. The brewing apparatus as claimed in claim 1, wherein arranged or formed on the sealing element (20) is a pressure-exerting element (28) which, during the brewing operation, is retained with a contact pressure against an extraction substance arranged in the brewing chamber (19). 7. The brewing apparatus as claimed in claim 1, wherein the brewing chamber (19) can accommodate one or more portion packs with coffee which are retained with a contact pressure between the base (12) with the outflow (40) and a pressure-exerting element (28) which is arranged on the opposite side. 8. The brewing apparatus as claimed in claim 1, wherein a fixed nozzle (11) is installed within the sealing element (20) through which a fluid flows into the brewing chamber (19). 9. The brewing apparatus as claimed in claim 1, wherein at least one pin (24) for aligning the pressure-exerting element (28) is integrally formed on the sealing element (20). 10. The brewing apparatus as claimed in claim 1, wherein a prestressed shut-off valve (41) is provided on the outflow (40) of the brewing chamber (19). 11. The brewing apparatus as claimed in claim 1, wherein the sealing element (20) has a contour which is adapted to beverage portion packs and the cross section of the brewing chamber (19). 12. The brewing apparatus as claimed in claim 1, wherein a fluid guide for the brewing operation and a fluid guide for moving the sealing element (20) are separate from one another.
