Abstract
A sanitary water fitting having a bearing ring arranged as a sliding bearing between the fitting body and the bearing sleeve. The bearing ring seals off a circling groove holding sealing rings from the bearing sleeve and is itself sealed off from the bearing sleeve by means of an external seal placed at the bearing ring. In its axial extension it borders a water passage opening which is between a circulating water channel and a swivel spout connection piece. The advantage of this invention is that the water flow in the circulating water channel and towards the swivel spout connection piece is controlled in such a way that the formation of lime deposits in the area of the sealing rings is considerably limited even after a relatively long period of operation, or even prevented completely. Since the water can no longer get in between the parts moving in relation to each other and the bearing ring itself helps to protect the sealing rings, there is no longer a possibility of serious levels of lime deposits settling in this sensitive area.
