GAS TURBINE ENGINE MODULE Russian patent published in 2019 - IPC F01D11/00 F01D25/24 

FIELD: machine building.

SUBSTANCE: gas turbine engine module comprising a movable wheel rotatably mounted inside the crankcase of the module and surrounded by segmented O-ring (18), which comprises an annular row of ring sectors, wherein each sector of the ring comprises at least one circumferential hook configured to interact with the crankcase annular fixing guide, wherein the module further comprises a segmented annular protective spacer (50) which is mounted between the ring sectors and the crankcase guide hooks and comprises an annular row of spacer sectors, characterized in that edges (60) of the gating sectors circumferential ends are not aligned with circumferential ends (58) edges ring sectors along module longitudinal axis.

EFFECT: invention allows better protection of crankcase guide, since gases that could pass between edges of circumferential ends of ring sectors are retained by sectors of laying (due to their angular displacement relative to ring sectors) and cannot reach crankcase guide.
