Title (EN) A HYDRAULICALLY DAMPED ACTUATOR
(FR) ACTIONNEUR À AMORTISSEMENT HYDRAULIQUE
Abstract:
(EN) A hydraulically damped actuator for closing a hingedly connected closure system. The actuator comprises a tubular cylinder barrel (218), an energy storing mechanism for storing energy when the closure system is being opened and for restoring the energy to close the closure system and a hydraulic damping mechanism for damping a closing movement of the closure system. The damping mechanism comprises a closed cylinder cavity (244) that is partly formed by a collar (220) that is integrally formed with the tubular cylinder barrel (218), a guiding element (251) that is bolted to said collar (220) and a piston (247) that is irrotatably and slideably with respect to the tubular cylinder barrel (218) coupled to said guiding element (251). As such, the guiding element (251) is fixedly positioned with respect to the tubular cylinder barrel (218), without needing a screw connection. Therefore, the actuator has a simpler and stronger construction and an additional sealing ring can be avoided.
(FR) La présente invention concerne un actionneur à amortissement hydraulique destiné à fermer un système de fermeture articulé. L'actionneur comprend un corps cylindrique tubulaire (218), un mécanisme d'accumulation d'énergie permettant d'accumuler de l'énergie lorsque le système de fermeture est ouvert et de restaurer l'énergie en vue de fermer le système de fermeture et un mécanisme d'amortissement hydraulique permettant d'amortir un mouvement de fermeture du système de fermeture. Le mécanisme d'amortissement comprend une cavité cylindrique fermée (244) qui est en partie formée par un collier (220) qui est formé d'un seul tenant avec le corps cylindrique tubulaire (218), un élément de guidage (251) qui est boulonné audit collier (220) et un piston (247) qui est accouplé irrotatif et coulissant audit élément de guidage (251) par rapport au corps cylindrique tubulaire (218). Ainsi, l'élément de guidage (251) est positionné à demeure par rapport au corps cylindrique tubulaire (218), sans nécessiter de liaison par vis. Par conséquent, l'actionneur présente une conception plus simple et plus résistante, et l'utilisation d'un anneau d'étanchéité supplémentaire peut être évitée.
