Abstract

LA PRESENTE INVENCION CONSISTE EN UN ACUMULADOR HIDRONEUMATICO QUE COMPRENDE UNA ESFERA CON LA CAVIDAD INTERNA SUDIVIDIDA EN DOS CAMARAS, UNA CON GAS, OTRA CON LIQUIDO, POR UNA MEMBRANA ELASTICA IMPERMEABLE A LOS GASES Y A DICHO LIQUIDO. LA MEMBRANA ESTA FORMADA POR UNA PELICULA (1) DE UN COPOLIMERO IMPERMEABLE A LOS GASES, PORTADOR DE GRUPOS - OH, POR DOS CAPAS (2, 3), ENTRE LAS QUE SE INTERCALA LA PELICULA, DE UN MATERIAL FLEXIBLE Y ELASTICO DE UN COPOLIMERO PORTADOR DE BLOQUES POLIAMIDA Y BLOQUES POLIETER Y, EVENTUALMENTE, POR UN REVESTIMIENTO (4, 5) DE GOMA DISPUESTO EN POR LO MENOS UNA DE LAS CAPAS DE MATERIAL FLEXIBLE Y ELASTICO. SEGUN UNA VARIANTE PREFERENTE, LA MEMBRANA ESTA FORMADA POR UNA PELICULA EVOH DISPUESTA ENTRE DOS CAPAS DE POLIETER BLOQUE AMIDA, ESTANDO EL CONJUNTO RECUBIERTO EN CADA CARA DE GOMA X-NBR. DE APLICACION EN EL AMBITO DE LOS VEHICULOS AUTOMOVILES.
