Abstract

Dispositif à soupapes comportant au moins deux obturateurs commandés directement par les cames d'un arbre à cames pour être amenés en contact ou hors de contact avec les sièges correspondants des soupapes. Des ressorts de compression 17 intercalés entre les cames 20 et les obturateurs 7, déterminent la force de fermeture entre le siège 8, 9 et l'obturateur 7, et assurent une compensation des tolérances relatives à l'écart entre la came 20 et l'obturateur 7. Application par exemple, à l'inversion du sens de déplacement de commandes hydrauliques.
