Abstract
L'invention concerne un amplificateur de freinage à dépression. Celui-ci comprend un mécanisme à leviers de réaction comportant des leviers de réaction 6, 7, une plaque support 15 et un ressort 14 disposé dans un couvercle 12 fixé au boîtier de commande 1. Une plaque de réaction 22 sur laquelle appuie la tige de poussée 19 est placée dans des évidements du boîtier et n'est pas fixée à la tige de poussée guidée dans un manchon 18 du couvercle 12. On évite ainsi les exigences de précision de montage de la plaque de réaction sur la tige de poussée. L'invention s'applique aux amplificateurs de freinage à dépression pour véhicules à moteur.
