Abstract
A sealing device for a movable shaft arranged between a high-pressure space and a low-pressure area of a pressure-resistant housing bounding the high pressure space. The sealing device includes a deformable pressure ring and a sealing ring that surrounds the shaft and is partially deformed by the deformable pressure ring. The pressure ring is supported under pressure at an outer circumference of the sealing ring, with the sealing ring resting either against or almost against the shaft.
