Abstract

La invención se refiere a un sistema de dirección asistida hidráulica con un centro cerrado. Según la invención, un acumulador recargable (11) puede conectarse con un servomotor (4) por medio de válvulas controlables reductoras de presión (78), controlando dichas válvulas la presión del motor, según un valor fijado, que está predeterminado por un dispositivo de control (15). Si se requiere, también se genera una conexión entre el motor (4) y un depósito relativamente libre de presión (12).
