Abstract

The seal separates from a surrounding atmosphere (4), a fluid which is present under excess pressure in a space (3) inside a housing (2). A pressure medium is fed to the gap in the seal via a conduit (8) and a pocket (7). The medium flows outwards to the atmosphere surrounding the housing and the housing internal space. The seal gap tends to be closed through the housing component (6) being elastically suspended in the housing using a pliant membrane (9), and pressed by pressure in the housing space against the flange (5).
