    The invention provides a banjo fitting (10) for a fuel tank, the fitting including a rotatable valve (12) which is movable from a first position in which fluid is able to pass therethrough to a second position in which the fluid flow is interrupted, the valve including a nut member that is releasable only with a specific tool, and spring means (20) located under the nut and bearing against the frustoconical swivelable portion (14) of the valve for a frictional and sealing fit with the valve body (12); the frustoconic -. al portion (14) is adapted to receive a handle (30) that is accessible to an operator whereby rotation of the handle (30) causes the frustoconical portion (14) to move between the two positions.

    WO 2014/028947 PCT/ZA2013/000041 BANJO FITTING FOR FUEL TANKS TECHNICAL FIELD OF THE INVENTION This invention relates to a banjo fitting and in particular to a banjo fitting for fuel tanks.
    BA CKGROUND ART Large vehicles often have two or more fuel tanks connected with hoses. The hoses areattached to the tanks by means of banjo fittings or bolts so that a particular tank can bedisconnected for cleaning and other purposes. The fittings are provided with valves forvthis purpose but this leads to tampering and theft of fuel.
    SUMMARY OF THE INVENTION , According to the invention a banjo fitting is provided with a rotatable valve which is movablefrom a first position in which fluid is able to pass therethrough; and a second position at an anglethereto in which the fluid flow is interrupted, the valve including a nut member that is releasable only with a specific tool, a spring assembly located under the nut and that bears against the j frustoconical swivelable portion of the valve for a frictional and sealing fit with the valve body; the frustoconical portion which has or is adapted to receive a handle that is accessible to an operator, rotation of the' handle causing the frustoconical portion to move betweenthe two positions.
    The body of the fitting may include a cut-out for access to the handle: _ The nut is preferably screwed into the body of the fitting and the spring assembly is locatedbetween the underside of the nut and the top of the frustoconical portion. A copper washer is located between the nut and the valve body.
    The fitting 'is attached to a tankso that it_ is swivelable therewith to provide for sympathetic movement that may be caused by road agencies- such as bumps, rocks and the like.BRIEF_ DESCRIPTION OF THE- DRA WINGSAn embodiment is described below with reference to the accompanying drawings, in which: Figure 1 is a sectionalview through a fitting according to the invention, WO 2014/028947 PCT/ZA2013/000041Figure is an exploded view of the fitting,Figure 3 is a view of the assembled fitting.l-JETAILED DESCRIPTION OF THE INVENT-ION ln the drawings, a conventional banjo fitting 10A is provided with a rotating valve member 12which has a frustoconical portion 14 which is swivelable in the body of the lfitting. The frustoconicalportion includes space 16 between its top surface and the lower surface 18 of 'a nut member toretain a compression spring 20 whereby the valveis maintained under pressure and in frictional engagement within the body. A copper washer 22 fits on the skift 24 of the nut.
    The banjo portion 26 of the fitting may also be provided with a copper or the like washer (not shown) to permit swivelling thereof as described above.
    The valve extends through the body and an orifice 28 is provided at itsend to receive ahandle 30, shown in a first position in which it is at right angles to the paper and a second positionwhich is indicated in broken' line 32. The latter position effectively disconnects the fuel flow throughpassage _34. _ I i .
    The lower end of the valve portion is sealingly maintained by virtue of an Ot-ring 36 andthere is a cut-out zone 38 that provides access for the handle to be screwed into a corresponding threaded orifice (not shown) in the body of the fitting.
    The connecting tube 40 may be male or female or any other configuration as required.
