The jet arrangement consists of a cylindrical housing (2,4) which has a connection (3) for the water supply at one end and a head (13), in which the jet (14) is mounted, at the other end. A hollow shaft (8), which is mounted on ball bearings (11,12) in the housing, is attached to the head A sealing disc (19) is connected to the end of the hollow shaft with a ring-nut (20). This disc is made from a wear resistant material, e.g. ceramic, and rotates with the jet. The side of the disc nearest the water inlet lies against a fixed sealing disc (25) which is also made from a wear resistant material. This disc is mounted in the housing. |
