Abstract

L'invention concerne un mécanisme formant soupape de relâchement pour un amplificateur hydraulique, par exemple pour un engin automobile. Selon l'invention, la soupape 55 de relâchement comprend une soupape principale 56 munie d'un siège de soupape 61 dont l'extrémité supérieure 61c, de faible surface, coopère avec le fond 57a d'un bouchon 57 pour former un étranglement supplémentaire, coopérant avec l'étranglement prévu dans l'amplificateur hydraulique associé à cette soupape de relâchement. L'invention s'applique aux circuits hydrauliques de commande des engins automobiles tels que les chariots élévateurs à fourche
