Abstract

Primer Certificado de adición a la patente P9402420 por válvula de elevación de ruedas de vehículo con elevación y descenso automáticos. Comprende una sola unidad que estructura tres distribuidores, principal, de accionamiento, de descenso automático, una válvula limitadora de caudal y un depósito estabilizador, pudiendo adoptar cada uno de los distribuidores dos posiciones estableciendo o interrumpiendo las conexiones entre las distintas vías de comunicación de las líneas de presión, de acuerdo con la existencia o ausencia de una presión secundaria de pilotaje, consecuencia a su vez de una respuesta automática programada; posee siete puertos de comunicación con el exterior que conectan con las líneas de presión derecha e izquierda de la suspensión y que conecta el mecanismo elevador; dispone una válvula opcional para desactivar el sistema de elevación y una electroválvula opcional para la elevación temporizada. De aplicación para la fabricación de válvulas para elevación y descenso automáticos de ejes de semirremolques de varios ejes.
