1. An aircraft engine, comprising:
an oil circuit fluidly connecting a reservoir of oil to components of the aircraft engine; and
a de-aerator fluidly connected to the oil circuit and located downstream of the components relative to a flow of the oil through the oil circuit, the de-aerator feeding the flow of the oil into the reservoir, the de-aerator having:
a nozzle extending from a nozzle inlet to a nozzle outlet along a flow passage delimited by a peripheral wall, the peripheral wall extending around a central axis of the nozzle, a flow circulating area of the flow passage decreasing from the nozzle inlet to the nozzle outlet; and
a deflector projecting from the peripheral wall of the nozzle at the nozzle outlet, the deflector having a curved section extending between a proximal end at the nozzle outlet and a distal end, the deflector intersected by the central axis of the nozzle.
