Abstract

Válvula de amortiguamiento para circuitos de trabajo, accionados por medios de presión, de un sistema de dirección para vehículos automóviles, con un alojamiento (28) y un canal de paso (19) situado entre dos conexiones de medio de presión y cuya sección transversal puede modificarse mediante un elemento de resorte (27) de extensión superficial, en que el elemento de resorte (27) tiene al menos un taladro central y actúa según la dirección de flujo alternativamente por dentro o por fuera, caracterizada porque el elemento de resorte (27) coopera con un contorno contrario (30) y el contorno contrario (30) tiene al menos un taladro (31) para el medio de presión de forma que se evita el elemento de resorte (27).
