Abstract

L'invention concerne une unité de rappel à accumulateur de force pour une porte (20), l'énergie accumulée étant fournie par un élément de pression. L'unité de rappel est caractérisée en ce que l'élément de pression est relié au moins indirectement avec un premier piston (2, 42) guidé axialement dans un premier cylindre (16). Ce premier piston (2, 42) définit dans le premier cylindre (16) une première chambre hydraulique (36) et la première chambre hydraulique (36) est reliée hydrauliquement par au moins un canal de liaison (39) à une deuxième chambre hydraulique (37) dans laquelle se trouve un deuxième piston (3, 42) qui est guidé axialement dans un deuxième cylindre (17). Le deuxième cylindre (17), sur le côté opposé à la deuxième chambre hydraulique (37), est relié au moins indirectement avec un amortisseur à gaz (38).
