摘要
A labyrinth seal system having at least two sealing fins arranged axially one behind the other on a rotor of a turbomachine and having a radially facing run-in element for the at least two sealing fins on a stator of the turbomachine, wherein in each case one radial sealing gap exists between the run-in element and the at least two sealing fins, wherein maxima of the radial sealing gaps are arranged offset with respect to one another in a circumferential direction, such that, in the region of the maxima, a passage exists in targeted fashion, for an air flow to the sealing fins that follow downstream, in the event of rubbing against the stator. This may be applied for example in a gas turbine engine.
