Tank device of an aero engine with an appliance for introducing oil

A tank device of an aero engine, comprising:

• an inlet for supplying an air-oil volume flow into a tank space of the tank device,
• an oil separator for receiving the air-oil volume flow supplied into the tank space and separating oil from the air-oil volume flow to form a reduced oil air-oil volume flow,
• a conduit positioned in the tank space and confined by a wall for receiving and guiding the reduced oil air-oil volume flow from the oil separator,
• an oil injector for injecting oil into the reduced oil air-oil volume flow guided through the conduit to form a further reduced oil air-oil volume flow, the oil injector arranged to inject the oil into the reduced oil air-oil volume in an injection direction substantially against a flow direction of the reduced oil air-oil volume flow guided through the conduit,
• an outlet through which the further reduced oil air-oil volume flow can be discharged from the tank space, the outlet including a valve for controlling the further reduced oil air-oil volume flow through the outlet.
