ABSTRACT:
The filter holder (9) is fitted on its inner wall with a plurality of equiangularly arranged radial bolts (12), preferably three, whereas the fixed support (2) is in turn fitted with respective spiral slots (13) in which the bolts (12) play, wherein when the filter holder is turned, driven manually through the handle (10), the filter holder travels axially at the same time; specifically, the filter (7), along with its respective coffee measure (8), moves towards the hot water supply extension (1) just before infusion takes place, or away in order for the coffee measure (8) to be replaced. These combined angular-axial filter holder (9) travelling elements enable the filter (7) to be perfectly coupled to the water outlet extension (1) without any unwanted side leakage.
