Abstract

Perfeccionamientos introducidos en las servo-direcciones; que llevan una caja de dirección con los conductos de admisión y de salida para el medio de la presión, con una corredura que va provista de ranuras y taladros para la distribución del medio de presión a través de un casquillo de válvula a las respectivas tuberías del medio de presión, que conducen a un motor de ajuste, y para el retorno de éste medio de presión al conducto de salida, y junto con una barra de torsión caracterizados porque; a) en el interior de la corredera está dispuesto un taladro axial que comunica con una tubería de salida para el medio de presión; b) que al taladro transversal procedente de la ranura de retorno entre corredera y casquillo de válvula, desemboca en el taladro axial; c) en el taladro axial está dispuesto un émbolo de válvula; d) que el émbolo de válvula está equipado con un resorte orientado en sentido contrario a la dirección de la corriente del medio de presión y que mantiene el émbolo de válvulaen una posición tal que, al no estar accionada la válvula de dirección, la sección transversal de la abertura del taladro transversal se encuentra sin estrangulamiento; e) que el émbolo de válvula está equipada con una superficie de presión que actúa en contra de la fuerza de el resorte; f) que la superficie de presión comunica a través de un taladro de presión, con una ranura dispuesta entre la corredera y el casquillo de válvula y expuesta a la presión de trabajo.
