Abstract

DISPOSITIVO SUPRESOR DEL RUIDO (10) PARA ABSORBER FLUIDOS IMPULSADOS. EL DISPOSITIVO TIENE UN RECEPTACULO (12) QUE DEFINE UN ORIFICIO (10) QUE SE PROLONGA AXIALMENTE. SE COLOCA COAXIALMENTE EN EL ORIFICIO UNA CAMARA ELASTICA (14). SE COLOCA COAXIALMENTE UN MECANISMO DE CARRETE CON LA CAMARA (14). EL MECANISMO DE CARRETE TIENE UNA CAPA INTERNA DEL CARRETE (80) Y UNA CAPA EXTERNA DEL CARRETE (90) QUE RODEA COAXIALMENTE LA CAPA INTERNA DEL CARRETE. LAS CAPAS INTERNA Y EXTERNA DEL CARRETE DEFINEN DIVERSAS PERFORACIONES (88, 98) QUE SE PROLONGAN A TRAVES DE LOS MISMOS. LAS PERFORACIONES (98) EN LA CAPA EXTERNA DEL CARRETE (90) ESTAN DESVIADAS CON RESPECTO A LAS PERFORACIONES (88) DE LA CAPA INTERNA DEL CARRETE (80) DE MANERA QUE SE EVITE UNA LINEA DIRECTA A TRAVES DE LA PRIMERA Y LA SEGUNDA PERFORACION.
