| 发明名称 | Sealing device for a turbomachine turbine nozzle | ||
| 摘要 | A sealing device for a nozzle of a turbomachine turbine including a turbine rotor. The turbine nozzle includes at least one inner annular platform. The turbine rotor includes a downstream spoiler disposed substantially axially. The sealing device includes at least one sealing sheet disposed, radially, between the inner face of the inner platform and the downstream spoiler of the rotor of the turbine so as to form an overlap clearance. | ||

| 主权项 | 1. A sealing device for a nozzle of a turbomachine turbine comprising a turbine rotor, said turbine nozzle comprising at least one inner annular platform, said turbine rotor comprising a downstream spoiler disposed substantially axially, said sealing device comprising: at least one sealing sheet disposed, radially, between the inner platform and the downstream spoiler of the rotor of the turbine, wherein the downstream spoiler of the rotor axially overlaps the inner platform, wherein the axial clearance between the sealing sheet and the turbine rotor is less than the axial clearance between the inner platform and the turbine rotor, such that the sealing sheet is crushed by the turbine rotor in the event of contact, and wherein the sealing sheet extends below a lower portion of the downstream spoiler. | ||
