FIELD: engines and pumps.
SUBSTANCE: turbo-pump unit (TPU), incorporating a rotor and a stator, according to the invention, is fitted with the controlled plunger with a working end face placed in the stator and mobile in the axial direction, and on the rotor the companion end face is provided, and in the working position of the plunger both end faces are in power contact for keeping of the rotor in motionless position. Besides, the stator is interconnected with the plunger by a tight bellow valve interconnected with the control pressure nipple, from the side, opposite to the working end face.
EFFECT: prevention of rotation of TPU shaft in the autorotation mode at purges and technological works on the engine for increase of resource of operation of bearings and other TPU elements.
