Abstract

In order to provide a sealing arrangement for sealing between a first medium chamber filled with a first medium and a second medium chamber filled with a second medium, in the region of a component which is movable along the longitudinal axis, which can be easily manufactured and has low leakage, it is proposed that the sealing arrangement comprises a sealing element which comprises at least one dynamic sealing portion which is placed or placeable on the movable component, wherein the at least one dynamic sealing portion comprises at least two sealing lips between which a leakage reservoir is formed, wherein the leakage reservoir is partially delimited by two boundary surfaces of the sealing lips arranged facing one another, wherein the leakage reservoir is formed at least partially by a concave recess in at least one or between the at least two boundary surfaces of the sealing lips.
