Abstract

UNA BOMBA (14) QUE TIENE UN ALOJAMIENTO CONVENCIONAL, SELLADO (32) CON LIQUIDO PRESURIZADO Y GAS EN SU INTERIOR, UN EJE ROTATORIO (34) DISPUESTO A TRAVES DEL ALOJAMIENTO Y QUE FUNCIONA POR CENTRIFUGACION PARA PRODUCIR ROTACION DEL LIQUIDO DENTRO DEL ALOJAMIENTO, Y UN MONTAJE SELLADO (38, 40 , 42) DISPUESTO ENTRE EL ALOJAMIENTO Y EL EJE ROTATORIO. LA BOMBA UTILIZA UN DISPOSITIVO (92) PARA VENTILAR DESDE EL ALOJAMIENTO A SU EXTERIOR EL GAS QUE SUELTA EL LIQUIDO EN EL ALOJAMIENTO, COMO POR UNA GOTA EN SU PRESION, MIENTRAS QUE BLOQUEA EL ESCAPE DEL LIQUIDO. EL DISPOSITIVO VENTILADOR (92) INCLUYE UN CUERPO (94) EN FORMA DE UN OBTURADOR ENROSCADO EXTERIORMENTE Y MONTADO EN ROSCA A UN TALADRO (104) EN EL MONTAJE SELLADO, UN FLUJO FACILITA EL PASAJE (96) A TRAVES DEL OBTURADOR Y TIENE RESPECTIVAS APERTURAS DE ENTRADA Y SALIDA EN LAS PAREDES INTERIOR Y EXTERIOR PARA DAR COMUNICACION ENTRE EL INTERIOR Y EL EXTERIOR DEL ALOJAMIENTO SELLADO, Y UNA MEMBRANA MICROPOROSA (98) MONTADA AL OBTURADOR A TRAVESDE LA APERTURA DE ENTRADA DEL CANAL PARA PERMITIR AL GAS FLUIR MIENTRAS QUE BLOQUEA EL FLUJO DEL LIQUIDO.
