Abstract
A seal comprising a gap between e.g. a flange (5) on a shaft and an element (6) arranged in a surrounding housing (2) is used for separating a fluid in a space (3) in the housing from the space (4) surrounding the housing. A pressurized fluid is supplied to the gap via a conduit (8) and a pocket (7) and flows to the space (3) and the space (4). The gap tends to be closed by the fact that the element (6) is elastically supported in the housing (2) by ductile membranes (10,11) and is pressed against the flange (5) by the pressure in the space between the membranes.
