FIELD: engines and pumps.
SUBSTANCE: turbomachine rotor section has working blade locating grooves extending axially. Every said groove receive working blade including contact surface directed radially inward. To force coolant over rotor end face surface, plate-like sealing elements are forced by centrifugal force to fit in contact surface. To lock sealing elements against circular shift, at least one sealing element has a bore for locking element. Said locking element is locked in said bore and seat aligned therewith and made in blade root. Locking element is locked in said seat by Z-shape plate with first end abutting between sealing element and blade root end face.
EFFECT: simplified assembly/disassembly of locking element.
