Sealing system of rotary piston machines, characterized in that the rotor comprises rotor discs (1, 2) which are arranged next to one another, are seated on the common rotor axle and are pressed apart from one another by acting spring and/or gas forces in the joints (11) between the discs in such a way that those end sides (6, 8) of the discs (1, 2) which point towards the side 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 inner flow around the rotor are present in the part joints between the discs (1, 2).
Système d'étanchéité de machines à piston rotatif, caractérisé en ce que le rotor est constitué de disques de rotor (1, 2) disposés en juxtaposition, qui sont montés sur l'axe de rotor commun et qui, par les forces de ressort et/ou de gaz agissant dans les fentes de séparation (11) entre les disques, sont écartés l'un de l'autre de telle sorte que les côtés frontaux (6, 8), tournés vers les parois latérales du boîtier, des disques (1, 2) s'appliquent en étanchéité contre ces parois et empêchent ainsi le fluide d'accéder aux axes. Des groupes de lamelles façonnées mobiles (3, 4) sont présents dans les joints de séparation entre les disques (1, 2) ; ces lamelles s'adaptent aux largeurs variables de joint et empêchent un écoulement interne autour du rotor.
