Abstract

Ce dispositif anti-dérapant comprend un maître-cylindre et au moins un cylindre de frein des roues associés à une pompe. Un premier passage 33, 32, 36, 38, 23 pouvant communiquer avec le maître-cylindre, est capable d'effectuer une opération d'anti-dérapage. Un deuxième passage 20, 17a, 17b, 17c peut communiquer avec le maître-cylindre. Un dispositif de vanne comprend une chambre 18 pouvant communiquer avec le cylindre de frein des roues, un élément de soupape 20 pour fermer la première ouverture 24 de la chambre 18 et une tige de vanne 30a qui traverse cette première ouverture en direction de la deuxième ouverture 17d de la chambre. Un piston 15, 17 sensible à la pression peut être manoeuvré en réponse à la pression de commande et il ferme la seconde ouverture avant que la première soit découverte. Applications notamment au système de freinage d'un véhicule.
