Abstract

SE PROPONE UNA VALVULA DE MEZCLADO PARA LA ADICION DE UNA CORRIENTE DE FLUIDO CALIENTE (15), EN ESPECIAL UNA VALVULA INVERSORA DE GASES DE ESCAPE DE UN MOTOR DE COMBUSTION INTERNA. LA VALVULA DE MEZCLADO SE HA EJECUTADO CON UNA CARCASA DE PLASTICO (10) PARA GUIAR LA CORRIENTE DE FLUIDO FRIA (14) Y UNA PIEZA DE CONEXION (12) QUE ALIMENTA UNA CORRIENTE DE FLUIDO CALIENTE (15), QUE FORMA UN ASIENTO ESTANCO PARA UN ELEMENTO DE CIERRE DE VALVULA (11) Y ESTA UNIDA A LA CARCASA DE PLASTICO (10). LA PIEZA DE CONEXION (12) TIENE UNA ABERTURA DE SALIDA (24), A TRAVES DE LA CUAL SE AÑADE LA CORRIENTE DE FLUIDO CALIENTE (15) A LA CORRIENTE DE FLUIDO FRIA (14), Y MUESTRA AL MENOS DOS SUPERFICIES DE CORRIENTE (40), QUE ESTAN ENFRENTADOS TRANSVERSALMENTE A LA DIRECCION DE CORRIENTE DE LA CORRIENTE DE FLUIDO FRIA (14) Y SE EXTIENDEN EN LA DIRECCION DE CORRIENTE DE LA CORRIENTE DE FLUIDO FRIA (14). LAS SUPERFICIES DE CORRIENTE (40) SE HAN CONFIGURADO COMO CHAPAS DE GUIADO DE FLUIDO, QUE SE HAN DISPUESTO ALMENOS EN LA ZONA DE LA ABERTURA DE SALIDA (24) Y APANTALLAN LA CARCASA DE PLASTICO (10) RESPECTO A LA CORRIENTE DE FLUIDO CALIENTE ALIMENTADA (15).
