PREVENTING AIR LOCKS INTERUPTING FLOW IN LIQUID FUEL FEED SYSTEMS IN AERONAUTICAL ENGINES

摘要

An air arrester device that can be connected into the fuel line of an airplane to interrupt the passage of a bubble of air moving through the fuel line, the device including a vertically oriented elongated container which includes an inlet duct connected to its lower end and an outlet duct which extends downwardly through its upper end and into the interior of the container, the outlet duct including at least one intake port located at about half way along the length of the container to enable fuel in the container to flow into the outlet duct and upwardly out of the container. Under negative G conditions an air bubble which has passed into the container via the inlet duct will be located below the intake ports while under normal conditions it will be located above the intake ports.
