  • Patent number: 6450552
    Abstract: A sanitary fixture comprises a fixture housing, in which a receiving chamber for at least one element controlling the water flow, e.g. a plate cam cartridge, is constructed. The receiving chamber is sealed at the bottom by a base (1). Secured in at least one through bore (2, 3, 15, 20) of the base (1) is a pipe connector (4), via which the water is supplied to the sanitary fixture from the domestic line. The pipe connector (4) is provided for axial securing to the base (1) with a circumferential bead (16), which is not completely circular, but comprises a recess (17) in a given circumferential region. The through bore (2, 3, 15, 20) in the base (1) comprises a lower, effective inlet aperture for the pipe connector (4), which has a non-circular cross section. Only after an undercut does the through bore (2, 3, 15, 20) then continue in known manner with a circular cross section.
