Abstract

Se proporciona un amortiguador de fluido que incluye una porcion de cuerpo hueco, un primer extremo y un segundo extremo. La porcion de cuerpo hueco tiene una superficie exterior corrugada o conformada y se llena con un medio compresible. El primero y segundo extremos del amortiguador hacen contacto con la pared interior de la linea que transporta fluido para estabilizar la posicion del amortiguador dentro de la linea que transporta fluido para optimizar el amortiguamiento de las pulsaciones de presion en el fluido. El amortiguador se forma al extruir o formar la porcion de cuerpo hueco a la longitud deseada, sujetar y sellar el primero y segundo extremos por un procedimiento de apilado con calor. El amortiguador se puede elaborar de un material o materiales que sean impermeables y resistentes al fluido dentro del sistema de fluido. El amortiguador se forma integralmente, por lo que se eliminan las etapas de soldadura o manufactura y se reducen los costos de fabricacion. Se enfatiza que este extracto se proporciona para cumplir con las reglas que requieren de un extracto y para permitir a un investigador u otro lector determinar rapidamente la materia objeto de la descripcion tecnica. Se afirma que con la compresion no se utilizara para interpretar o limitar el alcance o el significado de las reivindicaciones. 37 CFR 1.72 (b).
