Abstract

EL VEHICULO TIENE DOS GRUPOS (24, 26) DE LAMINAS QUE TRANSFIEREN FLUJO HACIA, Y RECUPERAN FLUJO DESDE UNA PARED (10) DE UNA TUBERIA. EL FLUJO VIENE DE UNA BOBINA (20) O DE UN IMAN O IMANES PERMANENTES. CADA GRUPO ES UN GRUPO SIMPLE DE MIEMBROS PARA LAS LAMINAS COMUNES (59) INTERCALADAS CON SEPARADORES (69); O ALTERNATIVAMENTE CADA GRUPO CONTIENE CONJUNTOS DE ELEMENTOS DE LAMINA COMUNES TAL COMO SEIS CONJUNTOS EN FORMA DE SECTOR, POR EJEMPLO. CADA LAMINA Y CADA SEPARADOR ESTA CORTADO A PARTIR DE UNA PLANCHA DE ACERO POR EJEMPLO ACERO INOXIDABLE. CADA LAMINA (25) ESTA DIRIGIDA HACIA EL EXTERIOR Y ES ELASTICAMENTE DEFLECTABLE E INTEGRAL CON EL MIEMBRO COMUN PARA LAS LAMINAS QUE FORMA UNA MATRIZ ALREDEDOR DEL VEHICULO. LAS LAMINAS ESTAN SEPARADAS POR RANURAS (63) PREFERIBLEMENTE EN FORMA DE V. LOS CONJUNTOS SE SUJETAN JUNTOS MEDIANTE RETENES (73) Y PASADORES (71). EN LA TUBERIA (10) LAS LAMINAS SE DEFLECTAN COMO SE INDICA MEDIANTE LINEAS DE FRACTURA (32, 34). LA LONGITUD DE CADA LAMINA ES AL MENOS 200 VECES SU GROSOR. LA SEPARACION DE LAS LAMINAS DIVIDIDAS POR SU GROSOR ES AL MENOS LA UNIDAD. UNOS SENSORES (28) DETECTAN LOS ESCAPES DE FLUJO DEBIDOS A LA PERDIDA DE METAL DE LA PARED.
