Abstract

L'invention concerne les maître-cylindres hydrauliques du type fournissant une pression de sortie dont le rapport à l'effort d'entrée est variable. Le maître-cylindre comprend une chambre 155 de mise sous pression et une chambre de commande 157. Une soupape de réglage qui commande la pression dans la chambre de commande comprend un plongeur 191 qui est déplacé par les pressions régnant dans la chambre de mise sous pression et dans la chambre de commande à l'encontre d'un ressort 149 de rappel du plongeur en sens opposé pour soulever une bille 188 de son siège. L'invention est applicable aux dispositifs de freinage hydrauliques de véhicules.
