摘要：The invention relates to a sealing device for movable parts of high pressurearrangements, having a ring (6) which is placed on the pressure-space side in the opening(2) to be sealed off, can be subjected to forces, essentially radial to the axis (22) of themovable part (4), of the compressed medium and is penetrated by the movable

component (4), that end of the ring (6) which is remote from the pressure space having acircumferential recess (7) which faces the movable part (4) and accommodates acircumferential end projection (19) of a sleeve (5), which projection is matched to therecess (7), preferably with surface contact, faces the movable part (4) and is situated onthe pressure-space side, the ring (6) being pressed against the sleeve (5) by the pressureprevailing in the pressure space and, for the purpose of sealing off the pressure space,pressing the end projection (19) against the movable part (4). According to the invention,that (those) surface(s) (17, 17', 17'', 17''') of the end projection (19) of the sleeve (5) whichrests rest against the surface (40) of the recess (7) of the ring (6) deviates (deviate) inshape from a straight line in a section through the axis (22) of the movable component(4), from its end point (18) resting against the movable component (4) and situated on

the pressure-space side to its end resting against the inner surface (20) of the opening(2), and comprises (comprise) at least one straight region and/or at least one curvedregion.
