Abstract

BOMBA DIFERENCIAL MULTI-MODO PARA DESPLAZAMIENTO DE FLUIDOS (10) QUE PUEDE SUMINISTRAR AL MENOS DOS DOSIS MEDIDAS. LA BOMBA TIENE UNA CAMARA EN LA CUAL SE HALLAN MONTADOS UN PRIMER PISTON DE DETERMINADO DIAMETRO (21) Y UN SEGUNDO PISTON DE DIAMETRO DIFERENTE (24) QUE DEFINEN UN PRIMER UN SEGUNDO VOLUMENES PARA MOVIMIENTO RECIPROCO EN LA CAMARA. HAY UN ELEMENTO PARA CREAR UN MOVIMIENTO RECIPROCO DE LOS PISTONES, SEGUN SE DESEE, PARA OBTENER UNAS CAMBIOS DE VOLUMEN PREDETERMINADOS CORRESPONDIENTES AL MOVIMIENTO DE UNO O AMBOS PISTONES (21,24). EXISTE UN SISTEMA DE ACCIONAMIENTO Y UNA CAMARA MEZCLADORA (100), UTILES EN RELACION CON LAS DOSIS DE LA BOMBA (10), QUE ESTAN CONECTADOS A ESTA.
