Claim:
Coffee machine for making a coffee beverage by means of pre-packed and pre-portioned coffee pouches ( 10 ) comprising a brew chamber which includes a brew chamber top ( 3 , 47 , 56 ) and a brew chamber base ( 9 ), said brew chamber top ( 3 , 47 , 56 ) being movable by means of a locking mechanism along a virtual substantially vertical axis from an elevated position to a position lowered on the brew chamber base ( 9 ) to form a tight brew chamber and being movable back into the elevated position where a carrier ( 8 ) of brew chamber base ( 9 ) can be pushed, in an essentially horizontal plane from a pushed-in position in which said brew chamber base ( 9 ) and said brew chamber top ( 3 , 47 , 56 ) are disposed coaxially relative to each other, into a drawn-out position in which a pouch ( 10 ) can be placed on said brew chamber base, and vice versa between these positions wherein: piercing elements are pressure-tightly supported at said brew chamber top ( 3 , 47 , 56 ) in a manner that they can be pushed sloping from above of said brew chamber top ( 3 , 47 , 56 ) into the interior of said brew chamber top ( 3 , 47 , 56 ) for releasably holding said pouch ( 10 ) in said brew chamber top ( 3 , 47 , 56 ) and pushed out therefrom, said brew chamber top ( 3 ) comprises a coulisse arrangement of an outer needle coulisse ( 29 ) and an inner needle coulisse ( 23 ), which coulisse arrangement is connectable with the locking mechanism, said outer needle coulisse ( 29 ) is solidly connected with said brew chamber top ( 3 ), in said outer needle coulisse ( 29 ) said inner needle coulisse is vertically movably guided and is connected to said outer needle coulisse by needle carrier aim units, each needle carrier arm unit each comprises an outer needle carrier arm ( 30 a , 30 b , 30 c , 30 d ) movable in said outer needle coulisse and an inner needle carrier arm ( 27 a , 27 b , 27 c , 27 d ) movable in said inner needle carrier coulisse, which are staggered next to each other, are inversely vertically sloped relative to each other and are solidly connected to each other at one of their ends each, and an actuation mechanism of said piercing elements for actuating said piercing elements relative to said brew chamber top ( 3 , 47 , 56 ) is coupled to the locking mechanism of said brew chamber so that after lowering said brew chamber top and thus locking the brew chamber, said actuation mechanism pushes said piercing elements into the interior of brew chamber top ( 3 , 47 , 56 ), and after elevating said brew chamber top and thus opening said brew chamber and after drawing out said horizontally movable carrier ( 8 ) into the drawn-out position, withdraws said piercing elements from the interior of said brew chamber top ( 3 , 47 , 56 ).
