Abstract

SE PROPORCIONAN UNA CONSTRUCCION DE VALVULA DE RECIRCULACION DE GASES DE ESCAPE Y UN METODO DE FABRICAR LA MISMA. LA CONSTRUCCION DE VALVULA COMPRENDE UN ALOJAMIENTO (24) PROVISTO DE UNA ENTRADA (25) Y UNA SALIDA (26) SEPARADAS POR UN ASIENTO DE VALVULA, UN MIEMBRO DE VALVULA MOVIBLE (28) LLEVADO POR EL ALOJAMIENTO (24) PARA ABRIR Y CERRAR EL ASIENTO DE VALVULA, Y UN MOTOR DE VELOCIDAD GRADUAL ACCIONADO ELECTRICAMENTE, LLEVADO POR EL ALOJAMIENTO (24) Y QUE ESTA FUNCIONALMENTE INTERCONECTADO AL MIEMBRO DE VALVULA (28) PARA POSICIONAR EL MIEMBRO DE VALVULA CON RELACION AL ASIENTO DE VALVULA. EL MIEMBRO DE VALVULA (28) Y EL ASIENTO DE VALVULA ESTAN DISPUESTOS DE MANERA QUE SEAN DE ACCION INVERTIDA, Y EL MUELLE ESTA INTERCONECTADO FUNCIONALMENTE AL MIEMBRO DE VALVULA (28) PARA TENDER A MOVER EL MIEMBRO DE VALVULA HACIA SU POSICION CERRADA CON EL ASIENTO DE VALVULA TRAS LA PERDIDA DE CORRIENTE ELECTRICA ALMOTOR.
