Definitions

  • the invention relates to a sanitary water fitting with a swivel spout, one end of which merges into a bearing sleeve which surrounds a fixed fitting body and is rotatably mounted thereon by means of at least one bearing ring and forms a circumferential water channel with the fitting body, which is closed off by ring seals, a valve control unit is arranged on the valve body, which is connected to the water inlet channels of the valve body and is connected via a water outlet channel thereof to the circulating water channel leading to the arm of the swivel outlet nozzle, which is delimited by circulating collars, the surfaces of which facing away from one another simultaneously form part of the wall form a circumferential groove for receiving the ring seals.

  • An upper and lower bearing ring are arranged on the valve body in the outer overlap regions of each of the swivel spout, which bearing rings preferably consist of a slidable, wear-resistant plastic. In its central area between the bearing rings, the swivel spout lies directly against the ring seals.
  • a disadvantage of such a design of the corresponding sanitary water fitting is that depending on the given water quality, and in particular the prevailing water hardness, limescale deposits can form in the area of the waterways inside the fitting after a more or less short period of operation , which leads to the stiffness of the swivel spout relative to the valve body, particularly in the area of the ring seals; can continue with a correspondingly violent rotation of the
  • Swivel spout Damage to the ring seals occurs with the result of leaks in the area of the waterways.
  • the invention is therefore based on the object of eliminating the aforementioned disadvantage and of creating a sanitary water fitting of the type mentioned which is simple in design and safe in operation. This object is achieved, including advantageous refinements and developments of the invention, from the content of the patent claims, which follow this description.
  • the basic idea of the invention provides that the ring seals arranged in the circumferential groove are shielded from the circumferential water channel or the bearing sleeve by means of separate sealing configurations.
  • the invention is associated with the advantage that the flow paths in the circulating water channel and towards the swivel spout are set such that the formation of limescale in the area of the ring seals is considerably restricted, if not prevented, even after a relatively long period of operation. Since the water can no longer penetrate between the parts moving against each other, limescale deposits of this level can no longer occur in this sensitive area.
  • the circulating collars are surrounded by rings which fill the space between the circulating collar and the bearing sleeve of the swivel spout and thus shield the ring seals from the circulating water channel. It has been found that in the aforementioned embodiment of the sanitary water fitting, the formation of limescale deposits in the area of the ring seals is considerably restricted, if not prevented, even after a relatively long period of operation.
  • the rings are connected to one another via webs, so that a single double ring body to be inserted into the water fitting is formed in the manner of a ring gear.

  • the axial extension of the two bearing rings 15 with an end edge 32 each delimit the passage opening 28 between the circumferential water channel 20 and the swivel spout 12.
  • the corresponding area of the two bearing rings 15 is in each case with one in the passage opening 28 and after on the outside facing the swivel spout 12 bevel 33. This ensures that the water flowing through the passage opening 28 is kept away from the remaining contact surface with the ring seal 22 between the peripheral collar 21 and the bearing ring 15 or is deflected therefrom. Since there is a seal both between the valve body 14 and the bearing ring 15 and between the bearing ring 15 and the bearing sleeve 13, the water cannot get between the components rotating against each other, so that no annoying limescale can form.

Abstract

L'invention concerne une robinetterie à eau sanitaire, comportant un élément d'écoulement pivotant, dont une extrémité se transforme en une douille-palier, qui entoure un corps de robinetterie fixe et forme conjointement avec lui un canal d'eau périphérique, rendu étanche par des garnitures d'étanchéité annulaires. Une unité de commande de clapet montée sur le corps de la robinetterie, est reliée au canaux d'amenée d'eau du corps de la robinetterie, et est raccordée par le biais d'un canal de sortie d'eau dudit corps de la robinetterie, au canal d'eau périphérique menant jusqu'au bras de l'élément d'écoulement pivotant, ledit canal d'eau périphérique étant délimité par une collerette périphérique dont les surfaces mutuellement opposées constituent simultanément une partie de la paroi de la rainure périphérique pour recevoir les éléments d'étanchéité annulaires. L'invention vise à éviter la formation de dépôts de calcaire sur les éléments d'étanchéité annulaires qui rendent étanche le canal d'eau périphérique dans le corps de la robinetterie. A cet effet, il est prévu que les éléments d'étanchéité annulaires (22) montés dans la rainure périphérique (29) soient protégés du canal d'eau (20) périphérique ou de la douille-palier (13), au moyen de structures d'étanchéité (24, 25; 15, 27) séparées.
