Abstract
An auxiliary supply device that includes: an auxiliary oil tank, an auxiliary pump including an inlet connected to the auxiliary tank and an outlet, a valve including a body having an inlet connected to the outlet of the auxiliary pump and a first outlet connected to the auxiliary oil tank, and a second outlet intended to be connected to a control system, the valve further having a member capable of moving within the body and configured to move between a first position in which the inlet of the valve is in fluid communication with the first outlet of the valve and a second position in which the inlet of the valve is in fluid communication with the second outlet of the valve.
Claims12
An auxiliary device for supplying oil to a control system for controlling variable pitch angle vanes for an aircraft turbine engine, the control system being supplied with the oil from a main oil tank under conditions of positive gravitational force experienced by the aircraft, the auxiliary device being intended to supply the oil to the control system under conditions of negative or zero gravitational force experienced by the aircraft, the auxiliary device comprising:
- an auxiliary oil tank,
- an auxiliary pump comprising an inlet connected to the auxiliary tank and an outlet,
- a valve comprising a body having an inlet connected to the outlet of the auxiliary pump and a first outlet connected to the auxiliary tank, and a second outlet intended to be connected to the control system, the valve further comprising a movable member movable in the body and configured to move between a first position in which the inlet of the valve is in fluid communication with the first outlet of the valve and a second position in which the inlet of the valve is in fluid communication with the second outlet of the valve.
An aircraft turbine engine comprising:
- the variable pitch angle vanes,
- the control system for controlling the vanes comprising:
- a control unit connected to a hydraulic actuator,
- an oil supply system comprising:
- a main oil tank,
- an oil supply pump comprising an inlet connected to the main oil tank and an outlet connected to the control system,
- wherein it further comprises the auxiliary oil supply device according to any one of the preceding claims.
