Abstract

La invención se refiere a un cilindro principal con reacción hidráulica para un sistema de freno con compresor neumático (12) que recibe una fuerza de compresión y un medio de reacción hidráulica montado de forma delizante en este pistón principal, que incluye un empujador (3), y que recibe una fuerza de actuación. La invención se caracteriza porque el medio de reacción hidráulica comprende además un pistón de cierre principal (4), un montaje hueco y escalonado (5), un pistón con cambio de relación (6), y tres muelles (71, 72, 73), estando el montaje dispuesto de una forma tal que el empujador (3), cuando se aplica la fuerza de actuación, recibe una fuerza de reacción solo proporcional a la diferencia entre la sección interna (51) y la sección externa (53) del pistón de reacción (5).
