Abstract

Perfeccionamientos introducidos en las válvulas de dirección con el centro cerrado; con por lo menos dos válvulas de asiento, caracterizados porque el espacio del resorte de las válvulas de asiento constituye la cámara de salida, mientras que el resorte de cierre actúa en contra de la fuerza que se produce por la caída de presión que se presenta en la válvula de asiento; que las piezas, que se encuentran en unión de impulsión con el dispositivo de accionamiento del vehículo, actúan sobre los resortes de cierre de tal modo que en caso de cambio en la orientación de las ruedas es reducida la fuerza del resorte de cierre que corresponde al sentido de la dirección.
