3. The beverage machine of claim 1 or 2, wherein said first assembly (2) is fixed relatively to said outermost casing (80), in particular fixed inside said casing, and said second assembly (3) is movable, or vice versa.
4. The beverage machine of any preceding claim, wherein said at least one of said assemblies (2,3) is movable against and away from the cooperating assembly along a substantially horizontal direction (3' ) , in particular in and out of a front part of said machine.

5. The beverage machine of any preceding claim, which comprises capsule opening means, such as one or more blades (10) and/or at least one puncture plate (13), located in the brewing chamber (7') and arranged to open said capsule (9) by penetration thereof in said straight direction (3' ) , in particular by closing said at least one of said assemblies along said straight direction (3' ) and thereby urging said capsule against the capsule opening means .
6. The beverage machine of any preceding claim, which comprises a lever (30) for moving said at least one of said assemblies (2,3) against and away from the cooperating assembly.
7. The beverage machine of any preceding claim, wherein one of said assemblies (2,3) has an outer part that is arranged to be hand-held for being driven directly by hand to and from the cooperating assembly, inwards and outwards the outermost casing, said one of said assemblies being optionally arranged as a spring loaded push assembly.
8. The beverage machine of any preceding claim, wherein said at least one of said assemblies that is/are movable outwards from and inwards into said outermost casing (80), has an outer face (H') which, in said closed position of the assemblies, is substantially adjacent and coplanar with an outer face 82 of the outermost casing (80) .
9. The beverage machine of any preceding claim, wherein the brewing unit (1) is associated with retaining means, such as bumps (41) optionally formed in capsule guiding slots (42) of the brewing unit, for retaining said ingredient capsule (9) between the assemblies (2,3) when in their open position, said retaining means (41) being optionally part of or movable with said at least one of said assemblies that is/are movable outwards from and inwards into the outermost casing (80) .
10. A beverage machine, in particular as defined in any preceding claim, comprising:
a brewing unit (1) which can be opened for introducing or removing an ingredient capsule (9), and closed for brewing said ingredient;

a passage (4,22) that has an opening (4', 22') and that is arranged for guiding said ingredient capsule (9) from the passage opening (4', 22') into the brewing unit (1) ; and
- a closing part (81) for closing the passage opening (4', 22') when the brewing unit (1) is closed,
wherein the closing part (81) is relatively movable over the passage opening (4', 22') in a generally parallel relative movement thereto, in particular in a relative sliding movement, from:
an open relative position in which said ingredient capsule (9) can be passed into the brewing unit (1) via the passage (4', 22'); to
a closed relative position, in which the passage opening (4', 22') is closed by the closure member (81), the closing part (81) optionally extending over edges of the passage opening (4', 22').
11. The beverage machine of claim 10, wherein the closing part (81) is relatively movable in a direction (3') generally transverse to a direction (9') of the passage (4,22) along which direction (9') said ingredient capsules (9) are guided to the brewing unit (1) .
12. The beverage machine of claim 10 or 11, wherein the closing part (81) has a generally plate-like shape that is arranged flat over the passage opening (4', 22') and relatively movable thereto, said machine having in particular a casing (80), such as an outermost casing, having a part (81) that forms the closing part.
13. The beverage machine of any one of claims 10 to 12, wherein the brewing unit comprises a first assembly (3) and a second assembly (2) cooperating together, at least one of said assemblies (2,3) being:
movable away from the cooperating assembly into an open position within said machine for forming between said assemblies at least part of said passage (4,22); and
movable to the cooperating assembly into a closed position for forming said brewing chamber (7'), the closing part (81) being optionally directly or indirectly fixed with said cooperating assembly.
14. A beverage brewing unit (1), in particular for a beverage machine as defined in any preceding claim, comprising:
- a capsule holding assembly (3) for holding a capsule in a position during insertion by gravity of the capsule (9) in the brewing unit; and
- a water injection assembly (2) for at least partially enclosing the capsule and providing water in the capsule, wherein the capsule holding assembly (3) forms a front part of the unit and is mounted to the water injection assembly (2) in a manner to be displaceable along a substantially horizontal path whereas the water injection assembly (2) is a rear fixed part of the unit.
15.
