Definitions

  • the present invention relates to a connecting element for detachable attachment to a valve arranged on a cavity, in particular a valve of a pneumatic tire or air tube, the connecting element being a connector for the detachable connection of a tube or the like connected to a liquid or gas source and on the side facing away from the connector End has a receiving opening for the valve and a flow passage is formed between the connector and the receiving opening in the housing of the connecting element, wherein a pressurized and movable closure element with a closure body for opening and closing the flow passage is arranged in the flow passage.

This ensures that the closure element is centered within the housing of the connecting element, so that no vibrations, turbulence or the like can occur within the flow passage even at higher pressures, since the closure element is evenly supported, supported and moved.
  • the through openings formed on the edge or in the closure body ensure a uniform passage of the liquid or gas in the open position and a corresponding blocking effect in the closed position of the closure element.
  • the diameter of the closure body is smaller than the diameter of the flow passage of the connecting element, wherein the closure body has at least two fin-like fin-like elements which form at least two through openings between them.
  • This inventive design of the closure body also ensures exact centering of the closure element within the connecting element.
  • the closure element or a first sealing ring of the closure element comes to rest on a pressure plate in the closed position in the direction of the receiving opening.

Abstract

La présente invention concerne un élément de raccord destinée à être mis en place de manière amovible sur un clapet donnant sur un espace creux, en particulier le clapet d'un pneumatique ou tuyau à air. L'élément de raccord (10) présente une partie de raccord (14) servant au raccord amovible d'un tuyau relié à une source de liquide ou de gaz ou analogue, ainsi qu'une ouverture de réception (16) destinée au clapet, se trouvant au niveau de l'extrémité voisine de la partie de raccord (14). Dans l'enceinte (12) de l'élément de raccord (10), entre la partie de raccord (14) et l'ouverture de réception (16), est formé un passage d'écoulement comportant un élément de fermeture (18) mobile pressurisé doté d'un corps de fermeture (22) servant à ouvrir et à fermer le passage d'écoulement. L'élément de raccord (18) présente au moins une ouverture de passage (26) formée au bord du ou à l'intérieur du corps de fermeture (22), permettant à un liquide ou à un gaz de pénétrer, le diamètre de l'élément de fermeture (18) correspondant approximativement au diamètre du passage d'écoulement de l'élément de raccord (10) dans cette zone.
