FIELD: turbo-machines.
SUBSTANCE: invention relates to a turbomachine having, in shaft housing (1), rotor shaft (2), at least one at a shaft end of rotor shaft (2) in impeller casing (5) arranged radial impeller (4) and with sealing arrangement (9) between flow cross-section (7) of impeller housing (5) and rotor shaft (2) within shaft housing (1) surrounding free space (8), said sealing arrangement (9) a plurality of spaced sealing elements (10A, 10B, 10C), for flow cross section ( 7) to separate from free space (8). According to invention entire seal assembly (9) with its sealing elements (10A, 10B, 10C) to radial gap (11) is arranged, whereby axial sections of rotor shaft (2) are free of seals.
EFFECT: invention improves operational characteristics of device.
