Combined pumping and separating machine for the oil circuit of a turbojet

Combined machine for pumping and separating into two distinct and purified phases a two-phase liquid/gas mixture or fluid at the intake of the machine, comprising means for the suction, pumping and partial separation of the two-phase fluid, means for drying and extracting the separated gas and means for degassing and forcing back the separated liquid, comprising at least three physically separated stages (A,B,C), intended to be activated by a means that is internal or external to the machine and built into a single casing (8):

• a first stage (A), equipped with an intake (4) for the two-phase fluid, in which the two-phase fluid is sucked, pumped and partially separated into two distinct phases, one phase being mainly liquid and the other being mainly gaseous;
• a second stage (B), comprising two zones:
• a first zone in which the mainly liquid phase extracted from the first stage (A) is degassed, and
• a second zone, equipped with a first outlet (9) for the dried gas, in which the mainly gaseous phase extracted from the first stage (A) is dried;
• a third stage (C), equipped with a second outlet (5) for the degassed liquid, in which the degassed liquid is forced back and pressurised.
