Abstract

Sistema hidráulico para dirección de vehículo que incluye: una válvula abierta en su posición central (3), una bomba (12) situada río arriba respecto a la válvula (3) para suministrar fluido hidráulico bajo presión a la válvula (3). Un limitador de circulación (8) situado río abajo, respecto a la válvula (3), a través del cual pasa el fluido hidráulico desde la válvula (3) hasta un depósito (11), teniendo dicho limitador de circulación un elemento desplazable (23) que responde a la presión del fluido hidráulico derivado desde una posición situada río arriba de la válvula abierta en su posición central (3) y río abajo respecto a la bomba (12) de tal manera que, cuando dicha presión del fluido hidráulico aumenta o disminuye en respuesta al desplazamiento de la válvula abierta en su posición central (3) respectivamente a partir de su posición neutral o hacia la misma, el elemento (23) se desplaza para aumentar o reducir, respectivamente, el grado de limitación del limitador de circulación (8)y un dispositivo de orientación por medio del cual el elemento desplazable (23) se orienta hacia una posición que corresponde al mínimo de limitación del limitador de circulación (8)
