FIELD: machine building.
SUBSTANCE: turbomachine includes a high pressure rotor, a low pressure rotor, a bearing located between rotors, a support with a sealing sleeve, and an oil supply and removal system to an oil tank of the low pressure rotor. A drain hole and an annular shoulder are made on the sealing sleeve of the low pressure rotor. Distance from bottom of the oil tank to the top of the shoulder on the low pressure rotor sleeve is at least 1.8 of the depth of the oil tank.
EFFECT: invention allows improving oil evacuation efficiency from the low pressure rotor cavity and reducing non-return oil flow rate.
