Abstract

ESTE DISPOSITIVO DE VENTILACION CONSTA DE UNA PLACA DE SUSTENTACION (1) QUE, EN SUS DOS LADOS OPUESTOS, LLEVA SENDAS PIEZAS DE CAMBIO DE DIRECCION (2,3). UNA MEMBRANA SIN FIN (9) CON PEQUEÑAS ABERTURAS (11) DISCURRE POR LA PARTE SUPERIOR DE LA PLACA (1), POR LAS PIEZAS DE CAMBIO DE DIRECCION Y POR EL ESPACIO INTERMEDIO ENTRE LOS EXTREMOS SUPERPUESTOS DE ESTAS PIEZAS, DEBAJO DE LA PLACA (1). DEBIDO A ESTE DISEÑO, EN CASO DE UNA SOBREPRESION, EL AIRE PUEDE SALIR HACIA ABAJO, ENTRE LAS PIEZAS (2,3) Y LA MEMBRANA (9), DE TAL MODO QUE ESTA NO SUFRA UNA DILATACION EXTREMADA.
