Abstract

Un absorbedor de energía hidroneumático mejorado para uso mas corrientemente en amortiguadores de vehículos automóviles, del tipo telescópico contráctil y extensible, consistentes en un par de elementos tubulares cilíndricos dispuestos entre sí de modo que se pueden deslizar con estanqueidad entre ellos, herméticamente cerrados por sus respectivas cabezas situadas en los extremos opuestos del dispositivo y en los que el elemento tubular exterior tiene en el extremo que está introducido en el otro elemento tubular un diafragma transversal con un orificio y el otro elemento tubular tiene un vástago que sobresale longitudinalmente de su cabeza y que, moviéndose con ella penetra más o menos en el orificio del diafragma, caracterizada porque tanto la cámara de volumen constante (40) definida en el elemento tubular interior (10) entre su cabeza (12) y el diafragma (28) como la cámara de volumen variable (42) definida en el elemento tubular exterior (20) entre la cabeza (22) y el diafragma (28) están parcialmente llenas de un líquido y terminadas de llenar con un gas a presión, sin separación entre el líquido y el gas, y porque el vástago (20) tiene, considerado desde su extremo suelto hacia su cabeza (22) una primera parte (34) de sección transversal prácticamente igual a la del orificio (30) del diafragma (28) y una segunda parte (36, 38) de sección transversal reducida respecto a la de la primera parte (34)
