Abstract

Perfeccionamientos en los amortiguadores hidráulicos telescópicos de tipo bi-tubo, en los que el tubo que contiene el pistón deslizante se halla rodeado por un segundo tubo que determina entre él y el primer tubo un espacio anular que contiene una reserva de líquido y un fluido comprimible, comunicando dicho espacio con el primer tubo por unos orificios con válvulas previstos en el fondo que cierra por su base al mencionado primer tubo, estando una de las citadas válvulas constituida por un anillo presionado por un muelle, que se caracterizan por el hecho de haberse practicado en la parte central del aludido fondo una primera serie de orificios destinados al paso del líquido desde el interior del primer tubo hacia la cámara anular de reserva, los cuales son controlados por una lámina fijada por su centro, así como también se ha practicado una segunda serie de orificios destinados al paso del líquido desde aquella cámara anular de reserva hacia el interior del primer tubo, orificios que se han abierto siguiendo una corona en la zona periférica del fondo y que tienen una sección total más grande que los orificios de la primera serie, viniendo controlados los referidos orificios de la segunda serie por medio de una válvula común constituida por un anillo plano presionado por un muelle
