The ball further has a passage, on and/or in which the water lance can be disposed. The bearing system is characterized in that a ball seat is provided and contains two axially interspaced bearing shells each of which has an opening, whereby the ball protrudes at least partially into the openings. A method for operating the bearing system that seals gaps, which can occur as the ball rotates, between the surface of the ball and the spherical contact surface of the at least one bearing shell. The bearing shells enable the bearing system to be easily assembled, and the small contact surfaces reduce the amount of friction during operation. In addition, the bearing system is also suited for use as a seal.
