Abstract

UN MECANISMO DE BOMBEO (42) QUE SE MUEVE EN AUMENTOS DE MOVIMIENTO (80) ESTA CONTROLADO PARA SEPARAR LOS AUMENTOS DE MOVIMIENTO EN PROPORCION DIRECTA CON EL VOLUMEN (76) QUE RESULTA DE CADA AUMENTO DE MOVIMIENTO. EN UN MODELO, LOS AUMENTOS DE MOVIMIENTO SON AGRUPADOS PARA DAR LUGAR A UNOS VOLUMENES POR GRUPO APROXIMADAMENTE IGUALES. EL MECANISMO SE MUEVE DE MANERA CONTINUA A TRAVES DE LOS AUMENTOS DE MOVIMIENTO EN CADA GRUPO. LOS GRUPOS ESTAN SEPARADOS PARA DAR COMO RESULTADO UNOS VOLUMENES DE FLUJO POR GRUPO APROXIMADAMENTE IGUALES. EL NUMERO DE GRUPOS DISMINUYE AL TIEMPO QUE LA VELOCIDAD DEL FLUJO AUMENTA. EL NUMERO DE AUMENTOS DE MOVIMIENTO EN CADA GRUPO Y EL VOLUMEN DE CADA GRUPO DISMINUYE AL TIEMPO QUE LA VELOCIDAD DEL FLUJO AUMENTA.
