Abstract

METODO Y APARATO PARA COMPROBACION DE FUGAS EN UN ENVASE, MEDIANTE EL CUAL EL APARATO (6) ES COLOCADO EN UNA FUNDA ESTANCA AL GAS Y DE FORMA LAMINAR. SE GENERA UN DIFERENCIAL DE PRESION ENTRE EL EXTERIOR Y EL INTERIOR, COMO RESULTADO DE LO CUAL EL ENVASE ES ESTRECHAMENTE ENFUNDADO POR LA FUNDA. ESTE DIFERENCIAL DE PRESION ES TAN GRANDE QUE HACE DISMINUIR EL VOLUMEN DEL ENVASE Y AUMENTA LA PRESION INTERNA DE LA PARTE SIN LLENAR DEL MISMO. EN EL ESPACIO (16) ("ESPACIO DE MEDICION") ENTRE EL ENVASE Y LA FUNDA PRENSADA CONTRA ESTE, SE UTILIZA UNA PRESION QUE ES MENOR QUE LA PRESION AUMENTADA DEL ENVASE. EN EL ESPACIO DE MEDICION HERMETICO, SE MIDE EL CAMBIO QUE SE PRODUCE EN LA PRESION DURANTE UN PERIODO DE MEDICION PREDETERMINADO.
