Abstract

Procédé et dispositif d'amplification de pression de frein (10) comportant un piston d'entrée (16) dans une chambre d'entrée (18) délimitant un volume intermédiaire (20) et un piston de sortie (34). Un poussoir (44) transmet la force d'entrée de freinage du piston d'entrée (16) au piston de sortie (34) et une installation d'application d'une force exerçant une force d'assistance de freinage sur le piston de sortie (34). Cette installation applique la force d'assistance sur le poussoir (44) ou encore transférer un premier volume de liquide de frein entre une partie (48, 50) du volume intermédiaire (20) et un réservoir externe (45).
