Abstract

EL DIFUSOR (8) COMPRENDE DOS TRAVIESAS CORRIENTE ARRIBA (9) Y CORRIENTE ABAJO (10) COAXIALES QUE DELIMITAN ENTRE SU UN CANAL ANULAR (19) Y UNA HENDIDURA ANULAR (20) QUE SE ABRE CORRIENTE ABAJO HACIA LA ENTRADA (6) DEL COLECTOR DE ADMISION (5). LAS TRAVIESAS (9, 10) ESTAN ENSAMBLADAS Y FIJADAS ENTRE EL CUERPO DE MARIPOSA (1) Y EL COLECTOR (5). LA TRAVIESA CORRIENTE ARRIBA (9) TIENE UN MURETE INTERNO TUBULAR (12) Y UNA RODAJA ANULAR (11) CON APOYO ESTANCO (17) AL MENOS CONTRA EL MURETE TUBLAR EXTERNO (16) DE LA TRAVIESA CORRIENTE ABAJO (10) QUE PRESENTA UNA RODAJA ANULAR RADIAL (15), QUE DELIMITA LA HENDIDURA (20) CON EL EXTREMO AXIAL CORRIENTE ABAJO (14) DEL MURETE INTERNO (12) DE LA TRAVIESA CORRIENTE ARRIBA (9). LA ALIMENTACION (21) DEL CANAL (19) CON GAS A RECICLAR ES RADIAL O TANGENCIAL, Y ESTOS GASES SON DIFUNDIDOS POR LA HENDIDURA EN EL CHORRO DE AIRE ENTRE LA SALIDA (2) DEL CUERPO DE MARIPOSA (1) Y LA ENTRADA (6) DEL COLECTOR DE ADMISION (5). APLICACION EN EL RECICLADO DE GASES CARBURADOS EN LOS MOTORES DE INYECCION PARA AUTOMOVILES.THE DIFFUSER (8) INCLUDES TWO CURRENT CROSSWAYS UP (9) AND CURRENT DOWN (10) COAXIALS THAT DELIMIT BETWEEN AN ANNULAR CHANNEL (19) AND AN ANNULAR CLEARANCE (20) THAT OPENS CURRENT DOWN TO THE INPUT (6) OF THE COLLECTOR OF ADMISSION (5). THE CROSSERS (9, 10) ARE ASSEMBLED AND FIXED BETWEEN THE BUTTERFLY BODY (1) AND THE COLLECTOR (5). THE CURRENT CROSS UP (9) HAS AN INTERNAL TUBULAR WALL (12) AND AN ANNULAR ROLL (11) WITH SEALED SUPPORT (17) AT LEAST AGAINST THE EXTERNAL TUBLAR WALL (16) OF THE CURRENT CROSS BELOW (10) RADIAL CANCEL (15), WHICH DEFINES THE SPLIT (20) WITH THE EXTREME CURRENT AXIAL BELOW (14) OF THE INTERNAL WALL (12) OF THE CURRENT CROSS UP (9). THE FOOD (21) OF THE CHANNEL (19) WITH GAS TO RECYCLE IS RADIAL OR TANGENTIAL, AND THESE GASES ARE DIFFUSED BY THE SPLIT IN THE AIR JET BETWEEN THE OUTPUT (2) OF THE BUTTERFLY BODY (1) AND THE ENTRY (6 ) OF THE ADMISSION COLLECTOR (5). APPLICATION IN THE RECYCLING OF CARBURGED GASES IN THE MOTORS OF INJECTION FOR CARS.
