Abstract: A filter device for filtering drinking water, having a connection device on which a receiving part for connection of a filter cartridge is pivotably mounted. The receiving part has a wall which is at least sectionally rotationally symmetrical and forms a convex sliding surface at which inflow and return channels for water to be filtered that lead to a filter connection open. The wall bears sealingly against an inner wall, curved coaxially therewith, of the connection device, and connection openings for an inflow and return of the water to be filtered open out at the inner wall. The receiving part is pivotable into a working position, in which mouths of the inflow and return channels lie sealingly over the connection openings, and into a changeover position, in which the filter cartridge can be removed from and/or inserted into the receiving part, and the wall of the receiving part sealingly closes off the connection openings for the inflow and outflow of the water to be filtered.

Abstract: In a connection device for coupling a gas pressure container provided with a connection coupling there is provided a guide device which is pivotable about a pivot axis between first and second pivoted positions, wherein the guide device includes an opening for inserting the gas pressure container in an insertion direction extending radially with respect to the pivot axis. A plug nipple is rigidly arranged on the connection device and projects into an inner region of the guide device such that the longitudinal axis of the nipple extends radially relative to the pivot axis and is situated parallel to the insertion direction in the first pivoted position of the guide device. The gas pressure container possesses a connection coupling with a rotationally symmetrical valve body having a coupling opening for receiving the plug nipple.

Abstract: A multifunctional water outlet fitting for selectively dispensing service water and filtered drinking water has a fitting member having at least one water supply, a first outlet for service water which branches off from the fitting member, a second outlet for filtered drinking water which branches off from the fitting member and, for a drinking water filter, a filter receiving space through which water can flow connected to the second outlet so as to carry water. The filter receiving space is formed by a filter housing which is arranged at the end of the second outlet facing away from the fitting member, and the filter housing has a downwardly facing base in which there is formed a mouth opening, from which filtered drinking water can be removed. The filtered drinking water is consequently removed directly from the filter housing so that any formation of germs in a connected waterway is prevented.

Abstract: In a filter insert for use in a water outlet fitting with integrated drinking water filter, which has a structure closed on all sides and with an inner hollow space and in which at least a part of its outer surface is designed as a filter-active surface through which water to be filtered passes from the outside inward, a mouthpiece pointing outward in the shape of a collar and forming a mouth orifice is arranged which can be received by an opening in a fitting-side filter housing and from which filtered water can flow freely out of the inner hollow space without contact with the filter housing.
