  • Patent number: 11872879
    Abstract: A fuel pick-up device (10) for a fuel tank (13) has a head (11) for fitting to a wall of the tank (13), and an elongate body (14) which extends from the head (11) into the tank (13). A water separator disposed in body comprises an axially-extending separation chamber (18), and a vane (21) for creating a helical flow of fuel flowing through the chamber between an inlet (17) and an outlet (23), wherein any water in the fuel entering the separation chamber through the inlet (17) moves radially outwardly in the helical flow away from the outlet (23), the outlet (23) being arranged such that fuel drawn from the chamber (18) is substantially free of water. Water separated from the fuel is collected in a chamber (25) and can be removed via a drain (24).
    Type: Grant

  • Publication number: 20200369144
    Abstract: A fuel pick-up device (11) for a fuel tank (10) comprises a float (17) arranged for rising and falling with the level of fuel (F) in the tank (10) and a plurality of elongate flexible tubes (16a, 16b) extending helically from the float (17) to a fuel outlet (15) of the device (11), the float (17) being arranged for generally vertical movement within an apertured sleeve (13). The flexible tubes (16a, 16b) are sufficiently thin to allow the float (17) to freely rise and fall with the level of the fuel (F). However, the combined cross-sectional area of the ducts provided by the plurality of flexible tubes (16a, 16b) is sufficient to allow fuel to be drawn from the tank at a high flow rate sufficient for large engines.
