Title
(EN) HYDRAULICALLY DAMPED ACTUATOR AND SELF-CLOSING HINGE COMPRISING THE ACTUATOR
(FR) ACTIONNEUR À AMORTISSEMENT HYDRAULIQUE ET CHARNIÈRE À FERMETURE AUTOMATIQUE COMPRENANT L'ACTIONNEUR
Abstract
(EN)
A hydraulically damped actuator for closing a hinged closure member (1). The actuator comprises: an energy storing mechanism for storing energy when opening the closure member (1) and using the energy to close the closure member (1); a damping mechanism for damping a closing movement of the closure member (1) having a closed cylinder cavity (40) filled with hydraulic fluid; and a pressure compensation mechanism comprising an expansion channel (69) with a plunger (70) that is slidably received therein for compensating changes of a volume of the hydraulic fluid upon temperature variations. The plunger (70) divides the expansion channel (69) into a first compartment (71) in fluid communication with the cylinder cavity (40) and a second compartment (72) that is sealed off from the first compartment (71) by the plunger (70). The expansion channel (69) provides space to allow the hydraulic fluid to expand without resulting in excessive pressures that would damage the closed cylinder cavity (40).
(FR)
La présente invention concerne un actionneur à amortissement hydraulique permettant de fermer un élément de fermeture (1) à charnière. L'actionneur comprend : un mécanisme d'accumulation d'énergie permettant d'accumuler de l'énergie lors de l'ouverture de l'élément de fermeture (1) et d'utiliser l'énergie en vue de fermer l'élément de fermeture (1) ; un mécanisme d'amortissement permettant d'amortir un mouvement de fermeture de l'élément de fermeture (1) comportant une cavité cylindrique (40) fermée remplie de fluide hydraulique ; et un mécanisme de compensation de pression comprenant un canal de dilatation (69) doté d'un piston plongeur (70) qui est reçu coulissant en son sein en vue de compenser des changements d'un volume du fluide hydraulique lors de variations de température. Le piston plongeur (70) divise le canal de dilatation (69) en un premier compartiment (71), en communication fluidique avec la cavité cylindrique (40), et un second compartiment (72) qui est isolé du premier compartiment (71) par le piston plongeur (70). Le canal de dilatation (69) fournit un espace destiné à permettre au fluide hydraulique de se dilater sans produire de pressions excessives qui endommageraient la cavité cylindrique (40) fermée.
