Abstract

Amortiguador hidroneumático de uso especialmente en el parachoques de los vehículos automóviles, del tipo que comprende un par de tubos acoplados telescópicamente, cada uno de los cuales está herméticamente cerrado por el extremo del dispositivo y en cuyo interior hay ensamblado con posibilidad de deslizamiento estanco un pistón de separación que divide el interior del dispositivo en una cámara de gas situada entre el pistón y la caperuza del tubo interior y una cámara de aceite dividida a su vez por un diafragma transversal con válvula fijado en el extremo del tubo interior que está introducido en el tubo exterior, caracterizado porque el diafragma con válvula está constituído por un disco rígido (30) con una serie circular de taladros (32) que en su superficie (48) del lado del pistón tiene un obturador (34) de la salida de los taladros (32) a esta superficie (48) y que está constituído por un paquete de arandelas elásticas (50, 52, 54) fijadas en el centro del disco (30), teniendo el diafragma además unos conductos (64, 66) abiertos permanentemente cuya sección de paso es bastante menor que la sección total de paso de los taladros (32) dispuestos circularmente.
