Abstract

La invención se relaciona con un aparato. Para lograr el sellado eficiente, el aparato comprende un sellado con una pluralidad de elementos de sellado (2"") colocados generalmente en una configuración anular alrededor de una abertura central. Cada elemento de sellado comprende una superficie de sellado opuesta a la abertura central. Por lo menos una cámara (13"") se incluye para recibir las secciones de los elementos de sellado (2""). Una entrada para una fuente de fluido proporciona a por lo menos una cámara (13"") el fluido para generar una sobrepresión que actúa sobre las secciones de los elementos de sellado recibidos en por lo menos una cámara (13""), para presionar y para mover las superficies de sellado de los elementos de sellado hacia la abertura central.
