FIELD: engines and pumps. ^ SUBSTANCE: device for oil drain from central drive of gas turbine engine makes it possible to prevent ingress of mechanical particles and chips into cavity of drives box by oil bleeding into separate pumping manifold, which results in higher reliability of gas turbine engine drive units operation. Pressure vessel comprises protective jacket, which envelopes shaft with minimum annular gap required for assembly. Protective jacket has receiving and internal cavities, which are tightly connected to drain pipeline, pumping pump, alarm filter, and are separated from cavity of drives box by protective jacket of fan cavity, central drive and compressor. ^ EFFECT: prevention of mechanical particles and chips ingress into cavity of drives box. ^ 1 dwg |
