Title (EN) CLOSING DEVICE FOR PNEUMATIC/HYDRAULIC MEMBRANE ACTUATORS
(FR) DISPOSITIF DE FERMETURE POUR ACTIONNEUR A MEMBRANE PNEUMATIQUE/HYDRAULIQUE
(DE) VERSCHLUSSANORDNUNG FÜR PNEUMATISCHE/HYDRAULISCHE MEMBRANAKTOREN
Abstract:
(EN) The invention relates to a closing device for pneumatic/hydraulic membrane actuators, particularly for membrane cylinders (1, 2) of pneumatic brake systems. The closing device comprises a ring clamp (4) with at least one clamping area (13) and at least one closing area (7), said closing area being provided with a connecting element (8a, 8b), and a closing part (12) which can be arranged in the closing area (7) of the ring clamp (4). According to the invention, the closing device is characterized in that the closing part (12) is automatically oriented inside the closing area (7) relative to the membrane periphery (6) by coming into contact with the closing area (7) of the ring clamp (4).
(FR) L'invention concerne un dispositif de fermeture destiné à des actionneurs à membranes pneumatiques/hydrauliques, notamment à des cylindres à membranes (1, 2) de systèmes de freinage pneumatiques. Ce dispositif de fermeture présente une bride annulaire (4) comprenant au moins une zone de serrage (13) et au moins une zone de fermeture (7) pourvue d'éléments de raccordement (8a, 8b) ainsi qu'un élément de fermeture (12) pouvant être placé dans la zone de fermeture (7). Ce dispositif de fermeture se caractérise en ce que l'élément de fermeture (12) s'oriente automatiquement à l'intérieur de la zone de fermeture (7) et par rapport au bord de membrane (6), en venant en contact avec la zone de fermeture (7) de la bride annulaire (4).
(DE) Die Erfindung betrifft eine Verschlussvorrichtung für pneumatische/hydraulische Membranaktoren, insbesondere für Membranzylinder (1, 2) von Druckluftbremsanlagen. Die Verschlussvorrichtung weist eine Ringklammer (4) mit zumindest einem Klemmbereich (13) sowie zumindest einem mit Verbindungselement (8a, 8b) versehenen Verschlussbereich (7) sowie ein im Verschlussbereich (7) der Ringklammer (4) anordenbares Verschlussstück (12) auf. Erfindungsgemäß zeichnet sich die Verschlussvorrichtung dadurch aus, dass sich das Verschlussstück (12) mittels Eingriff in den Verschlussbereich (7) der Ringklammer (4) selbsttätig innerhalb des Verschlussbereichs (7) sowie zum Membranrand (6) ausrichtet.
