A door closer (20) is attachable to a door (24) and includes a cylinder (36) which forms a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door. After the door (24) has been opened to a position, for example, of ninety-five to one hundred degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82). This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door. A passageway (150) is formed in cylinder (36) to allow fluid to flow relatively freely from chamber (44) to reservoir (82) until an inward end (56) of piston element (50) has travelled a prescribed distance "x." This prescribed distance of travel represents the opening of door (24) to ninety-five to one hundred degrees from the door's normally closed position.
Ferme-porte (20) comportant un cylindre (36) définissant une cavité (44) dans laquelle se déplace un piston (50), dont le mouvement, lorsque s'ouvre la porte (24), fait passer le liquide contenu dans la cavité (44) à un réservoir (82). Lorsque la porte (24) est ouverte au-delà d'un certain angle, par exemple entre quatre-vingt-quinze et cent degrés, le piston (50) comprime le liquide dans la cavité (44) et le force à passer via un clapet anti-retour (95) dans le réservoir (82), ce qui crée une force de résistance s'opposant à une plus grande ouverture de la porte. Un passage (150) dans le cylindre (36) permet une circulation relativement libre du liquide entre la cavité (44) et le réservoir (82), tant que l'extrémité (56) du piston (50) n'a pas parcouru une certaine distance déterminée, correspondant à un angle d'ouverture de la porte (24) compris entre quatre-vingt-quinze et cent degrés.
