A hydraulic seal and an oil scavenge system are combined, and oil pumping gears and other associated equipment thus obviated. The hydraulic seal 32 comprises an oil reservoir holding centrifuged oil, and an annular fin 22, the periphery of which dips in the oil. The fin 22 has an orifice 33 which receives the oil under pressure derived from the speed of rotation of the oil, and passes it via conduit 34,26 to an oil sump.
