Abstract

LA INVENCION ESTA RELACIONADA CON UNA BOMBA, ESPECIALMENTE UNA BOMBA DE REFRIGERANTE REGULABLE, PARA AUTOMOVILES. LA INVENCION TIENE POR OBJETO DESARROLLAR UNA BOMBA, ESPECIALMENTE UNA BOMBA DE REFRIGERANTE REGULABLE PARA AUTOMOVILES, ACCIONADA POR OBRA DEL EJE DEL CIGUEÑAL DEL AUTOMOVIL, QUE SOBRE TODO NO NECESITA NINGUN RETEN PARA EJES PARA AISLAR EL ESPACIO DE CIRCULACION FRENTE AL CUERPO DEL COJINETE DE LA POLEA DE LA CORREA MOTRIZ Y AL MISMO TIEMPO REDUZCA SIGNIFICATIVAMENTE EL CONSUMO DE COMBUSTIBLE Y LAS EMISIONES EN TODO EL RANGO DE TRABAJO DEL MOTOR, NO SOLAMENTE EN LA FASE DE CALENTAMIENTO, Y QUE SE CARACTERICE ASIMISMO POR UNA EXCELENTE SEGURIDAD DE FUNCIONAMIENTO Y FIABILIDAD, ASI COMO POR SU BAJO COSTE DE FABRICACION Y FACILIDAD DE MONTAJE. SEGUN LA INVENCION, LA BOMBA SE CARACTERIZA POR QUE EL MOLINETE (21) DE LA BOMBA DE REFRIGERANTE ESTA ACCIONADO POR UN ACOPLAMIENTO MAGNETICO PERMANENTE, DONDE UNO DE LOS DOS ARBOLES DE ACOPLAMIENTO DEL CONJUNTO LLEVA UN IMAN ANULAR (24) MULTIPOLAR MAGNETIZADO POR SECTORES Y EL OTRO ARBOL DE ACOPLAMIENTO UN ANILLO DE MATERIAL DE HISTERESIS (ANILLO DE HISTERESIS 27) O UN ANILLO DE ESTE TIPO CON UN ANILLO DE COBRE MONTADO, DONDE LA SEPARACION ENTRE AMBAS MITADES DE ACOPLAMIENTO PUEDE MODIFICARSE DEPENDIENDO DEL CORRESPONDIENTE ESTADO DE FUNCIONAMIENTO DEL MOTOR.
