Abstract: Silencioso de expansión de gas, que comprende un terminal tubular (12) de conexión a una alimentación de gas a presión en flujo subsónico, y un escalón de baja presión 22 que comunica con el terminal (12) por una serie de orificios de entrada (20) con flujo del gas a velocidad sónica y que presenta unos orificios (28) de salida del gas a velocidad subsónica, estando el escalón de baja presión completamente lleno de un relleno metálico poroso (34), caracterizado porque el escalón de baja presión (22) comprende por lo menos dos partes cilíndricas (24, 26) de diámetros diferentes que comunican entre sí, estando la parte (24) de menor diámetro conectada con el terminal (12) citado y presentando la parte (26) de mayor diámetro los orificios de salida del gas, estando la parte de menor diámetro (24) conectada con la parte de mayor diámetro (26) por un codo que forma una pantalla entre los orificios de entrada (20) y los orificios de salida (28).

Abstract: The invention relates to a gas expansion silencer comprising an end piece (12) which is intended to be connected to a pressurised gas source and a low-pressure stage (22) consisting of two cylindrical parts (24, 26) having a small diameter and a large diameter respectively. The part (24) with the small diameter is linked to the end piece (12) and the part (26) with the large diameter comprises gas outlet ports (28). Said low-pressure stage (22) is filled completely with a porous metallic packing.
