Abstract

La présente invention relève du domaine de la construction automobile et concerne en particulier des dispositifs amortisseurs de suspension et peut être utilisée dans des amortisseurs de véhicules légers et de véhicules lourds de même qu'à d'autres fins techniques. L'amortisseur autoréglable à écoulement de fluide unidirectionnel par rapport à un piston d'amortisseur comprend un cylindre de travail pourvu de trous calibrés dans sa partie inférieure, un réservoir externe contenant le fluide de travail, une tige traversant une douille de guidage et un piston de travail à ressort pourvu de trous calibrés et de soupapes de dérivation. Selon cette invention, l'amortisseur comprend également un dispositif de commande externe présentant une variation continue prédéterminée de la capacité de transmission entre les cavités de l'amortisseur résultant de pressions générées dans la cavité de la tige. Ainsi, une augmentation de la pression dans la cavité de la tige réduit la capacité de transmission du dispositif de commande, augmentant ainsi la résistance de l'amortisseur à une valeur effective maximale. L'amortisseur comprend en outre un radiateur-échangeur thermique externe rempli de fluide d'amortissement et relié à un régulateur externe et à un réservoir extérieur par des tuyaux.
