Abstract

Amplificateur dont le piston est accouplé à un piston auxiliaire soumis à l'action d'un ressort et à celle de la pression d'un accumulateur. L'amplificateur 1 est placé entre la pédale 2 et deux paires de cylindres de frein de roue 3, 3' et 4, 4' appartenant respectivement aux circuits et II surveillés par l'élement 5 de réglage multiple d'une protection antiblocage reliés à une pompe 6 et un accumulateur 7. Le carter 8 comporte trois alésages 9, 10 et 11, un piston d'amplificateur 12, un ressort 13, une tige de piston 14, une soupape 15/16, un ressort 18, un piston auxiliaire 22 avec une tige 21 et un bras 20, un ressort d'accumulateur 25, une chambre d'amplificateur 29, des réservoirs 30, 59 et 60, une tige 32 agissant sur la soupape 34/35, une chambre de pression primaire 36, un piston 37, une chambre de pression secondaire 38, un palonnier 40, un tiroir 43, une soupape de commande 44, une chambre d'accumulateur 47, un poussoir de pédale 50, un piston 52, une chambre annulaire 53, une soupape anti-retour 55, des poussoirs 56, 57 et un dispositif de commutation 58, un capteur de niveau 61.
