ABSTRACT:
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.
