Abstract
A float device for use in drawing liquids such as fuel from a tank or other reservoir is disclosed. The device comprises a float 15 arranged for rising and falling with the level of liquid in the tank and a liquid pick-up duct, which comprises a flexible tube 14 having its free end coupled to the float 15. The float 15 is arranged for vertical movement within an elongate sleeve 10, which encloses the float 15 and the flexible tube 14. The sleeve 10 is tubular and comprises an open lower end and apertures 11 for filtration. A flanged top end cap 12 is provided. The float 15 may comprise a sealed upper chamber 16 and a portion 18 having an array of holes 19 for filtering the liquid. The float 15 may protrude from the lower end of the sleeve 10 so as to maximize liquid uptake when the liquid level is low.
Description
Float Device This invention relates to a float device for use in
drawing liquids such as fuel from a tank or other reservoir.
In conventional fuel tanks, the fuel is drawn from a point adjacent the bottom of the tank in order to enable the pick-up of fuel even when the level of fuel in the tank is low. However, a disadvantage of this arrangement is that any water and/or sediment which has accumulated at the bottom of the tank can be drawn up with the fuel.
UK Patent Number 0B2 350 337B discloses a solution to this problem in the form of a float device having a float arranged for rising and falling with the level of fuel in the tank, and a fuel pick up duct which comprises a flexible tube having its free end coupled to the float, the float being arranged for vertical movement within a filter which encloses the float and the flexible tube.
In use, the float ensures that the fuel entry or pick-up end of the tube is always adjacent the surface of the fuel in the tank. Accordingly, the pick-up point is always adjacent the surface of the fuel in the tank and thus the risk of drawing up a sediment or water is alleviated.
The filter in which the float moves vertically comprises an elongate perforated tube which is closed at its lower end by a solid or perforated end wall. A disadvantage of this arrangement is that the length of the filter needs to be accurate, otherwise it will abut the bottom of the tank and prevent the device from fitting properly. Alternatively, if the filter is too short, the pick-up end of the tube will not reach to the bottom of the tank and as such the fuel capacity of the tank is not maximised.
have now devised a float device which alleviates the above-mentioned problems.
In accordance with the present invention, as seen from a first aspect, there is provided a float device for use in drawing liquids such as fuel from a tank or other reservoir, the device comprising a float arranged for rising and falling with the level of liquid in the tank, and a liquid pick-up duct which comprises a flexible tube having its free end coupled to the float, the float being arranged for vertical movement within a filter or other member which encloses the float and the flexible tube, wherein the filter or other member is elongate and tubular in construction and comprises an open the lower end.
In use, the device operates in the same manner as the float device of UK Patent Number G82 350 337B. However, the lower end of the filter or other member is open thereby allowing the float to extend partially below the filter or other member when the level of fuel in the tank is low. in this way a device with a slightly shorter filter or other member can be fitted into a tank to ensure that the device fits and to allow for manufacturing tolerances or deformations in the tank. However, when the level of fuel is low, the float extends below the level of the filter or other member so that more fuel can be drawn from the tank compared with the device disclosed in UK Patent Number G82 350 3378. It will be appreciated that a device having a filter or other member of a particular length can thus be filled to tanks having a range of different depths.
The end of the tube may be outside the filter or other member when the fuel in tank is low and thus the float preferably carries filter means arranged to filter the liquid being drawn up the tube.
Preferably the float compnses a hollow chamber to which said tube is connected, the chamber comprising an apertured wall forming said filter means.
Preferably the apertured wall forms the bottom wail of the float, so that filtered fuel can be drawn right down to the point where the float buts the bottom of the tank.
Also in accordance with this invention, as seen from a second aspect, there is provided a float device for use in drawing liquids such as fuel from a tank or other reservoir, the device comprising a float arranged for rising and falling with the level of liquid in a reservoir, and a liquid pick-up duct which comprises a flexible tube having its free end coupled to the float, the float being arranged for vertical movement within an enclosure which encloses the float and the flexible tube, wherein the float carries filter means arranged to filter liquid being drawn up the tube.
Preferably the float comprises a hollow chamber to which said tube is connected, the chamber comprising an apertured wall forming said filter means.
Preferably the aper-tured wall forms the bottom wall of the float.
Preferably the bottom surface of the float is profiled or comprises projections which prevent the apertured wall from abutting the bottom surface of the tank and thereby inhibiting the flow of liquid.
An embodiment of the present invention will now be described by way of an example only and with reference to the accompanying drawing, the single figure of which is a sectional view through a float device in accordance with the present invention.
Referring to the drawing, there is shown a float device for fitting to a circular aperture formed in the top wall of a fuel tank (not shown). The device comprises an elongate circular-section of filter in the form of a metal sleeve 10 provided with an array of apertures 11. The sleeve 10 is open at its lower end and closed at its upper end by a flanged end cap 12, which is arranged for securing around its periphery to the edges of the aperture in the fuel tank.
A rigid feed pipe 13 extends through the end cap 12, the lower end of the pipe 13 being connected to an elongate coiled flexible tube 14 of plastics material. The lower end of the flexible tube 14 is connected to a float 15 by means of a tubular connector 20.
The float 15 is generally circular in section and is arranged to freely move vertically within the sleeve 10 with the level of fuel in the tank. The float 15 comprises a sealed upper chamber 16 which is filled with air and a separate bottom chamber 18 having bottom and side walls which are provided with apertures 19. The bottom chamber 18 comprises an outlet duct connected to the flexible tube 14 via the connector 20.
In use, when fitted to a fuel tank, the float 15 floats on the surface of the fuel and fuel is drawn into the lower chamber 18 through the apertures 19 and along the flexible tube 14. The apertures 19 serve to filter the fuel and prevent sediment and other matter from being drawn up the flexible tube 14. The apertures 11 in the sleeve 10 also serve to prevent sediment and other matter from entering the device.
As the level of fuel falls, the lower end of the float 15 moves out of the sleeve 10 as shown, thereby allowing fuel to be drawn to a level slightly below the sleeve 10.
In this manner, the volume of fuel in the tank can be maximised even if the sleeve 10 does not reach fully to the bottom of the tank.
