Sealing device between blade stages and a rotary drum, particularly for preventing leaks around the stages of straightener blades

A device for ensuring the sealing in a rotary machine between a rotor and fixed blade stages. Blade edges are joined by rings carrying circular seals in slots. Springs force the seals in the longitudinal direction towards transverse faces of reinforcements of the rotor. A turbulence-free gas flow is...

Beschreibung
Zusammenfassung:	A device for ensuring the sealing in a rotary machine between a rotor and fixed blade stages. Blade edges are joined by rings carrying circular seals in slots. Springs force the seals in the longitudinal direction towards transverse faces of reinforcements of the rotor. A turbulence-free gas flow is obtained as a result of the total seal obtained by the seals (19). Moreover, the rotor can be constructed with a substantially rectilinear ferrule which only induces limited stress concentrations.
