The present invention relates to a seal ring (106) for axially sealing two parts (102, 104) arranged so as to be able to move axially with respect to one another. The seal ring (106) has two sealing lips which are arranged circumferentially on an axial first end side of the seal ring (106). In this context, the sealing lips are designed such that they can be spread apart from one another by a first fluid pressure of a first fluid volume to bear in a sealing manner against mutually opposing sealing faces of a first (102) of the parts. The seal ring (106) also has a sealing projection which is arranged circumferentially on a second end side of the seal ring (106), oriented axially away from the first end side. In that context, the sealing projection is designed in order, when in a state bearing against a sealing surface of a second (104) of the parts, to seal the first fluid volume in a region (132) arranged radially inward with respect to the sealing projection against a second fluid volume at a second fluid p
