Abstract
A turbine engine includes an oil supply system that has a main oil tank, a supply pump with an inlet and an outlet connected to a control system, an auxiliary oil tank, and a valve having a first inlet connected to the main tank, a second inlet connected to the auxiliary tank and an outlet connected to the inlet of the supply pump. The valve also has a member configured to move within the body and 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.
Claims16
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, and
- 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 connected to the inlet of the supply pump, 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.
The method according to claim 13, further comprising between steps (b) and (c) as well as between steps (d) and (e), a step of transmitting an electrical signal to the valve by an electrical control unit, wherein a deactivation period (t1) is defined between the detection of the first operating state in step (d) and the displacement command in step (e).
