1. A turbine engine for an aircraft, comprising:
variable pitch angle vanes,
a control system for controlling the vanes comprising a control unit connected to at least one hydraulic actuator, and
an oil supply system comprising:
a main oil tank,
a supply pump comprising an inlet and an outlet connected to the control system,
an auxiliary oil tank,
a valve comprising a body having a first inlet connected to the main tank, a second inlet connected to the auxiliary tank and an outlet, the valve further comprising a mobile member in the body and configured to move between a first position in which the first inlet of the valve is in fluid communication with the outlet of the valve and a second position in which the second inlet of the valve is in fluid communication with the outlet of the valve, and
a centrifugal pump arranged between the valve and the supply pump, the centrifugal pump having an inlet connected to the outlet of the valve and an outlet connected to the inlet of the supply pump, the oil flowing from the valve to the supply pump through the centrifugal pump.
