Definitions

  • the invention relates to a filling device for a fuel tank, comprising a filling line which at a first end is in open communication with the fuel tank and at a second, opposite end is provided with a filling mouth designed to receive a filling pistol and accessible via a closable filling opening.
  • the invention relates in particular to a filling device for a fuel tank placed on board a ship.
  • FIG. 1 A fuel tank of a ship provided with a prior-art filling device is depicted in Fig. 1.
  • the device comprises an internal filling line (18) which at one end is in open communication with the fuel tank (17) and at an opposite end comprises a filling mouth (20) which is fastened in the gangway (6) of the ship.
  • a filling opening of the filling mouth (20) can be closed here by means of a cap (5).
  • the cap (5) is removed and a filling pistol of a pump installation is inserted through the filling opening thus made accessible into the filling mouth (20). Air and fuel vapour driven from the fuel tank (17) by this can escape through a vent line (16) and a vent nipple (15).
  • US-A- 4,615,362 a filling device has been provided to contain and store underground tank overfill of gasoline and diesel fuel.
  • the present invention has for its object to provide a filling device of the kind disclosed in US-A-4 615 362, wherein oil spillage is even further reduced.
  • a filling device according to claim 1 is designed with a splash guard.
  • the overflow chamber of the filling device according to the invention may be mounted in an existing filling device in that it is placed in the internal fuel hose.
  • the device according to the invention is characterized in that the tubular portion is provided with a connection sleeve for a filling hose to the fuel tank at an end facing away from the filling mouth.
  • the existing fuel hose possibly made shorter, is joined to the connection sleeve, and the overflow chamber is mounted to the deck in the desired location.
  • the overflow chamber comprises vent means and is provided at or at least near its bottom with a drain hole which is connected to vent means of the fuel tank via a discharge line. Any fuel spilled into the overflow chamber can then flow into the fuel tank through the drain hole, discharge line, and vent means.
  • the vent means in the overflow chamber ensure that a vent path from the fuel tank is nevertheless maintained during this.
  • FIGs. 2 and 3 An embodiment of the filling device according to the invention for use on board a ship is shown in Figs. 2 and 3 with the filling opening in a horizontal and in a vertical portion of the deck, respectively, more in particular in the gangway 6 and in a raised, vertical portion 19.
  • the filling device can be mounted on the existing fuel tank 17 of the ship, which does not require any special adaptations for this purpose.
  • the filling device comprises an overflow chamber 1 which surrounds a tubular portion 2 of the filling device in the relevant area, see Fig. 5A.
  • the tubular portion 2 is mounted in the chamber 1 in a manner impermeable to liquids and comprises at its free end a filling mouth 20 inside the overflow chamber 1 for receiving a filling pistol of a pump installation.
  • the tubular portion 2 comprises a connection sleeve 11 for connection to an existing, possibly shortened filling hose 18 to the fuel tank 17.
  • the overflow chamber 1 is provided with a filling opening 25 through which the filling mouth 20 is accessible to a filling pistol.
  • the filling opening 25 is provided with an internal thread into which a cap 5 can be screwed, which cap is provided with a mating external thread for this purpose.
  • the material of the overflow chamber 1 is a HD polyethylene or aluminium, both being particularly well resistant to petrol and diesel fuels.
  • the overflow chamber 1 can be mounted in any rotational position in the horizontal plane relative to the fuel line cap 5. As a result, the ideal position of the chamber 1 relative to the cap 5 can always be found when the former is mounted, for example, below the gangway of a ship.
  • the fuel overflow chamber 1 is so designed that it can be connected adjacent any fuel line cap 5 fitted with a standard hose connector of, for example, 50 mm or 38 mm diameter.
  • the fuel overflow chamber 1 can be mounted directly to the fuel line caps 5 already present in many cases, provided sufficient space is available for the chamber 1.
  • Fuel line caps 5 are often fitted with a long filling connection; the latter should preferably project easily over the internal filling line 2 when a fuel overflow chamber 1 is used.
  • the overflow chamber 1 is fitted with fastening means in the form of two fastening eyelets 10. It is in fact preferable to mount the chamber 1 to, for example, the deck by means of two strips or similar parts. The strips then absorb the weight of the chamber 1 and of any fuel present therein as well as the forces exerted by the fuel hose (18).
  • a rubber closing piece 4 is fastened to the - possibly shortened - fuel line cap 5 by means of at least two stainless steel hose clips 7 in the present embodiment of the invention.
  • Two hose clips 7 are used because this offers more security and certainly also because ISO guidelines for yacht construction will render this compulsory in the future.
  • the rubber used for the closing piece 7 is highly resistant to petrol and diesel fuels and is provided with a reinforcement fabric.
  • a rubber splash guard 3 is mounted between the rubber closing piece 7 and the chamber 1.
  • the rubber closing piece 7 and the splash guard 3 are fastened to the chamber 1 by means of a stainless steel retaining ring 9 and screws 8.
  • the rubber splah guard 3 has a central opening 31 from which a number of incisions 32 extend radially outwards. This serves to render possible the ready insertion of filling pistols of different diameters, for example for petrol and diesel, into the internal filling line 2.
  • the tubular portion 2 of the internal filling line may form an integral whole with the housing of the overflow chamber, for example, it may be integrally cast or injection-moulded thereto, or as in the present example may be formed by a separate insert which is mounted with exact fit in the filling connection sleeve 11 so as to be impermeable to liquids.
  • a fuel supply hose 18 is mounted to the connection sleeve 11, again with two hose clips 7, the tubular portion 2 of the internal filling line will be held securely and leak-free in the connection sleeve 11 after the hose clips 7 have been tightened.
  • the tubular portion 2 is internally provided with a kind of screwthread at the area of the filling mouth 20 in the form of a number of circumferential ridges 21.
  • the filling mouth is further fitted with a flared end so that a filling pistol can be easily guided into it.
  • the overflow chamber has a capacity of approximately 3 litres, which was found to be sufficient in practice. All fuel present in the chamber 1 after tanking has ended will flow back into the fuel tank 17 through the connection 12 in the bottom and the vent hose 16 coupled thereto.
  • vent hose connection 12 When fuel flows towards and into the fuel tank 17 during filling of the tank, air will want to flow from the tank to the exterior. This air will escape through the vent hose 16. The air will enter the overflow chamber 1 through the vent hose connection 12. It will be able to escape to the outside because the overflow chamber 1 is also provided with vent means, i.e. a vent hose connection 13 and the vent hose 16 coupled thereto.
  • the overflow chamber 1 in the present example is even fitted with two vent hose connections 13, see Fig. 5B, to enable the ship builder to connect the vent hose there where it is most convenient.
  • the connection 13 which is not used is or remains sealed. Fuel rising inside the vent line 16 at the end of the tanking process and threatening to escape to the exterior through the vent line 16 is also effectively caught in the overflow chamber in this embodiment, so that any pollution of the environment is avoided.
  • the vent means 13, 16 of the chamber 1 are in communication with an externally mounted vent nipple 15, with or without an interposed odour filter 14 as in the present example.
  • the vent nipple 15 must always be mounted at a higher level than the fill cap 5.
  • the connection 13 serves not only to allow air driven from the fuel tank to escape to the exterior through the vent nipple 15; inversely, air can flow towards the fuel tank 17, for example when fuel is being consumed.
  • the odour filter 14 mounted between the connection 13 and the vent nipple 15 prevents the air escaping from the fuel tank from spreading an unpleasant diesel smell.
  • a filtering material comprising a particular type of activated carbon is provided in the fuel odour filter 14.
  • the activated carbon absorbs the molecules causing the diesel smell from the air flowing past.
  • the activated carbon filter must on no account come into contact with liquid fuel. It is to be preferred, accordingly, that the odour filter 14 should be mounted as far above the fuel overflow chamber 1 as possible. If the fast-flowing air should contain some drops of fuel, these will be separated from the air in the chamber 1 before the air issues to the exterior through connection 13.
  • the filling device according to the invention can also be used if the fuel line cap 5 is not mounted in a deck or gangway 6, but instead in a vertical wall of, for example, a raised deck structure 19 as depicted in Fig. 4.
  • the tubular end 2 of the internal filling line is then allowed to be mounted in one manner only: sloping in downward direction so that as little fuel as possible can flow from the filling opening 25.
  • the fuel overflow chamber 1 also counteracts at least partly another problem associated with the existing filling device:
  • the following problem may arise when a fuel tank 17 on board a ship has been filled to capacity.
  • the tank from which the fuel originates lies below ground and has a temperature of 10°C.
  • the fuel tank of the ship has a capacity of, for example, 5001.
  • the ship is not used after being filled up, but owing to fine, hot weather the temperature in the ship rises to 35°C.
  • the fuel is also heated up thereby.
  • the temperature rise will cause the fuel to expand.
  • the coefficient of thermal expansion of, for example, diesel fuel is 0.000875.
  • the 500 will expand to approximately 5111.
  • the invention offers an overflow protection against the unwanted escape of a liquid fuel and the accompanying environmental pollution during filling of a fuel tank caused by a too late switching-off of a filling pistol or by e.g. the thermal expansion of the liquid fuel.
