Abstract

Ce ressort est du type de ceux constituées par un cylindre contenant de l'huilet et/ou un gaz sous pression et dont l'intérieur est divisé par un piston monté sur une tige en deux chambres à volume variable, pouvant communiquer entre elles par des passages ménagés dans le piston, la tige de piston étant guidée de façon etanche à l'extrémité du cylindre par laquelle elle sort de celui-ci et le piston présentant une section de passage qui s'ouvre lorsque la tige de piston se déplace vers l'extérieur du cylindre. Le ressort selon l'invention comporte un dispositif de blocage 9, 10, Il, 12 agissant en fonction de la pression pendant la course de rentrée de la tige de piston 2. On obtient ainsi un ressort mieux adapté à certaines applications, par exemple lorsqu'il est associé au couvercle du coffre d'un véhicule automobile
