A water filter comprises a cap (70) having an inlet (84) and an outlet (74), a valve (88) being provided in the inlet (84). A housing (10) has a filter cartridge (26) removably contained in the housing. Valve opening means in the form of a ramp like projection (56) is provided on an upper end cap (40) of the filter cartridge (26). The housing is connected to the cap by a bayonet fitting.

L'invention concerne un filtre à eau comprenant un chapeau (70) qui comporte une entrée (84) et une sortie (74), l'entrée (84) étant équipée d'une soupape (88). Ce filtre comprend en outre un boîtier (10) dans lequel une cartouche (26) de filtre est installée de manière amovible. Des moyens d'ouverture de soupape comprenant une protubérance (56) en forme de rampe sont placés sur le capuchon couvrant l'extrémité supérieure de la cartouche (26) de filtre.
