FIELD: machine building.
SUBSTANCE: turbomachine includes a high pressure rotor, a low pressure rotor, a bearing, a support with a sealing sleeve, an oil supply and removal system to an oil tank of the support. High pressure rotor includes graphite seals. Low pressure rotor includes a sealing sleeve and graphite seals. The bearing is located between the rotors. The turbomachine is equipped with a drain hole and an annular shoulder made on the support sealing sleeve. Distance from bottom of the oil tank to the top of the shoulder on the support sleeve is at least 1.2 of the depth of oil tank.
EFFECT: inventions allow increasing the efficiency of oil evacuation from the turbomachine support, reducing nonrecoverable oil flow at simultaneous increase of bath oil volume and reducing the weight of the support and dimensions.
