Abstract (en)
[origin: CA2074326A1] 91/062 In a The device for sealing the gap between the rotor blades and the casing (2) of a turbomachine, configured with a conical profile (28), the rotor blades (6) are fitted with circumferential shroud plates (11), which seal by means of serrations (12, 13, 14) against the casing by the formation of radial gaps (16, 17). The tips (24, 29) of the conical ends of the blades (6) seal against the casing (2) at the inlet and outlet ends, and the shroud plate (11) located centrally at the end of the blade has three throttle locations relative to the casing, the inlet end throttle location bounding a diagonal gap (19). The end of the blade is provided with a positive offset (31) relative to the passage profile, which protrudes into a gap relief chamber (25) located in the vane carrier (2). (Fig. 2)
