Zusammenfassung:A device for sealing a high pressure region in a turbomachine from a low pressure region; the turbomachine has one or more statoric parts and one or more rotoric parts; the device comprises a labyrinth seal having a first plurality of grooves and a second plurality of grooves; the first plurality of grooves is disposed in a helical pattern and the second plurality of grooves is disposed in a cylindrical pattern; the labyrinth seal is disposed between at least one of the one or more rotoric parts of the turbomachine and at least one of the one or more statoric parts of the turbomachine between the high pressure region and the low pressure region of the turbomachine; the helical pattern has a helix angle less than or equal to 10°, wherein a stabilization effect of the turbomachine is obtained and leakage due to the second plurality of grooves is negligible.
