Oil separator rotor located in an enclosure provided with an oil reinjection system for lubricating a bearing. The oil separator rotor, which dries the excess air passing out of the enclosure, acts by aiding the deposition of suspended oil on the walls of a lining or packing of the rotor. The lining is a honeycomb material cartridge offering easy separation without excessive pressure losses. The rotor is assembled by bolts, which interconnect the end plates traversing the lining.

A system is disclosed for regulating oil and fuel temperatures in a turbojet engine having an engine accessory driven at constant speed by a power transmission which is driven by the turbojet engine. The system has a first closed oil circuit for circulating oil through the turbojet engine, a second closed oil circuit for circulating oil through the power transmission, a fuel circuit for supplying fuel to the turbojet engine, an air/oil heat exchanger connected to the first closed oil circuit to pass oil in heat exchange relationship with air, an oil/fuel heat exchanger connected to the fuel circuit and to the first closed oil circuit downstream of the air/oil heat exchanger to pass oil and fuel in heat exchange relationship, and an oil/oil heat exchanger connected to the first and second closed oil circuits to pass oil in heat exchange relationship, the connection to the first closed oil circuit being downstream of the oil/fuel heat exchanger.

A device for the remote filling of an oil tank, particularly an oil tank of an aircraft engine, is provided with a lock which interconnects the inlet nozzle of the oil filler and the outlet nozzle of excess oil remover so that the oil supply pipe cannot be connected to the inlet nozzle to supply oil to the tank until the removal pipe has been connected to the outlet nozzle of the excess oil remover. The lock includes a locking member which engages in a notch in a slide valve housed in the inlet nozzle to prevent the valve from moving to open the nozzle while a slide valve in the outlet nozzle is closed, but which moves clear of the notch when the outlet nozzle slide valve is opened by connection of the removal pipe to the outlet nozzle.

A centrifugal oil filter comprises a bowl which is rotatable about a vertical axis within a fixed casing and which is open at its upper and lower ends, the inner wall of the bowl being provided with grooves which trap particles in the polluted oil fed into the bowl as the bowl is rotated and the oil flows upwards along the wall under centrifugal action and which allow the particles to fall therefrom under gravity to a particle collector positioned below the open lower end of the bowl when the bowl stops rotating. The inner wall of the bowl is also formed with an annular recess above the particle trapping grooves. This recess fills with oil when the bowl is rotated, and this oil flows out and downwards along the wall under gravity when the bowl stops, thereby cleaning the filter wall.
