Abstract
EN LA FABRICACION DE UNA MEZCLA DE REACCION DE FLUIDOS DE AL MENOS DOS COMPONENTES DE REACCION FLUIDOS, TAMBIEN DIFICILMENTE MEZCLABLES, QUE REACCIONAN CONJUNTAMENTE CON MATERIAL MACIZO O MATERIAL ESPONJOSO, SE CONSIGUE EN UNA EJECUCION COMPACTA UNA SEDACION RAPIDA DE LA CORRIENTE DE MEZCLA DESPUES DE LA ESTRANGULACION EN LA SALIDA (22) DE LA CAMARA DE MEZCLA (8), EN DONDE LA CAMARA DE MEZCLA (8) DESEMBOCA EN UNA PERFORACION GUIA (17) DE UN CURSOR DE ESTRANGULAMIENTO (18) DISPUESTO TRANSVERSALMENTE , QUE ESTA COLOCADO DE FORMA CONCENTRICA ALREDEDOR DE UN EMBOLO DE LIMPIEZA (20) GUIADO EN UN CANAL DE SALIDA (19). AL PASAR EL ORIFICIO DE ESTRANGULAMIENTO (22), LA CORRIENTE DE MEZCLA SE DIVIDE EN UNA CORRIENTE ANULAR, QUE DESAGUA EN UNA CORRIENTE DE DISMINUCION EN EL CANAL DE SALIDA (19).
