Abstract
The sealing arrangement comprises a seal having end sealing surfaces. The one end sealing surface bears against an annular sealing surface of a valve seat screwed into a lower part of a water faucet. The other end sealing surface presses upon a non-rotatable disk which bears against a rotary disk. The seal comprises radially outwardly projecting supporting ribs in the region of the end sealing surfaces. These supporting ribs are supported at a supporting ring of a housing of a ceramic upper part or portion. A slit spring washer bears against the seal at the inner or internal side thereof. With this sealing arrangement it is rendered possible that the seal has to be fitted into the water faucet with only a small bias or loading, because the seal efficiently utilizes the water pressure and converts or transforms such water pressure into a force which presses the end sealing surfaces with greaater compression or pressure against the annular sealing surface and the non-rotatable disk, respectively.
