Abstract (en)
[origin: EP2458157A1] The seal i.e. abradable pressure seal (7), has an abradable surface opposite to a rotor portion of turbomachine and another surface in contact with an inner ferrule of stator. A set of component units (10) is provided, where each component unit includes circumferential step (9) on the abradable surface to create an obstacle in the circumferential direction of the inner ferrule. Each component unit includes an axial step (8) on abradable surface to create an obstacle in the axial direction of the turbomachine, where the seal is made of silicone or epoxy.
