Abstract

EN UNA BOMBA DE INYECCION DE COMBUSTIBLE DE TIPO DISTRIBUIDOR SE DISPONE DE UNA VALVULA MAGNETICA EN EL DISTRIBUIDOR, CUYO COMPONENTE DE VALVULA ESTA COLOCADO EN UNA PERFORACION AXIAL EN EL DISTRIBUIDOR Y ES ACTUADO MEDIANTE UN IMAN INTEGRADO CON LA CARCASA A FIN DE INTERRUMPIR LA CONEXION DE UNA CAMARA (14) DE TRABAJO DE BOMBEO DE LA BOMBA DE INYECCION DEL TIPO DISTRIBUIDOR A UNA CAMARA DE LIBERACION DURANTE UNA FASE DE INYECCION DE ALTA PRESION DADA. DEBIDO A SU DISEÑO, UN DISTRIBUIDOR (7) DEL TIPO DE BOMBA DE COMBUSTIBLE TIENE UNA CIERTA TOLERANCIA AXIAL EN SU COJINETE QUE AFECTA AL DESPLAZAMIENTO DE CONTROL DEL MIEMBRO (39) DE VALVULA EN EL DISTRIBUIDOR EN RELACION AL ELECTROIMAN (36) FIJO. PARA PREVENIR CAMBIOS EN LAS PROPIEDADES MAGNETICAS QUE PUEDEN TENER LUGAR DEBIDO A SU DISPOSICION AXIAL, UNA PARTE DEL CIRCUITO MAGNETICO DE UNA PLACA (55) DE IMAN PUEDE SER MOVIDA CONJUNTAMENTE CON EL DISTRIBUIDOR DE FORMA QUE LA POSICION RELATIVA ENTRE UNA ARMADURA (52) FIJADA SOBRE EL MIEMBRO (39) DE VALVULA Y LA PARTE DEL NUCLEO DEL IMAN, QUE FORMA UN ESPACIO (80) DE AIRE DE TRABAJO, NO CAMBIA DEPENDIENDO DE LA POSICION AXIAL DEL DISTRIBUIDOR Y DE ESTA FORMA SE MANTIENEN LAS PROPIEDADES MAGNETICAS DE LA VALVULA ELECTROMAGNETICA CON REFERENCIA A LA POSICION AXIAL DEL DISTRIBUIDOR.
