Abstract
Se describe una unidad de conformidad (8), para usar en un sistema de frenado hidráulico, que está adaptada para absorber fluido hidráulico desde un cilindro director (1) durante el frenado normal y, en caso de que se detecte un fallo en el sistema de frenado, la unidad está adaptada para devolver fluido al cilindro director (1). Por lo tanto, la unidad de conformidad (8) disminuye efectivamente su conformidad en caso de un fallo. La unidad (8) puede comprender un par de pistones (14, 15) que trabajan en un orificio escalonado contra una fuerza de carga primera y segunda, con una tercera fuerza de carga variable prevista para contrarrestar la segunda fuerza de carga durante el funcionamiento normal, para proporcionar una conformidad aumentada.
