Abstract (en)
[origin: CA2671017A1] Sealing system of rotary piston machines, characterized in that the rotor comprises rotor discs (1, 2) which are arranged next to one another, are se ated on the common rotor axle and are pressed apart from one another by acti ng spring and/or gas forces in the joints (11) between the discs in such a w ay that those end sides (6, 8) of the discs (1, 2) which point towards the s ide walls of the housing bear sealingly against the latter and thus prevent the access of the medium to the axles. Assemblies comprising movable shaped lamellae (3, 4) which adapt to the changing joint widths and prevent an inne r flow around the rotor are present in the part joints between the discs (1, 2).
