Abstract
A fuel tank for an agricultural vehicle, comprises a main fuel tank 10 having a filler pipe 11 and a separate inlet 15 and a removable auxiliary tank 30 having a second filler pipe 32 and an outlet 36 for supplying fuel into the separate inlet 15 of the main tank. To avoid spillage from the filler pipe of the main tank 10, in one aspect of the invention, a valve 16 is provided in the main fuel tank 10 to close off the second inlet 15 when the fuel level within the main tank 10 reaches a predetermined level. In a second aspect of the invention, spillage is avoided by means of an extension tube 40 which sealingly engages the filler tube 11 of the main tank at its lower end and opens at its upper end into the filler pipe 46 of the auxiliary tank 30.
Claims12
A fuel tank for an agricultural vehicle, comprising
- a main fuel tank having first and second separate inlets and flow paths, wherein the first inlet includes a first filler pipe;
- a removable auxiliary tank having a second filler pipe and an outlet for supplying fuel into the second inlet of the main tank, wherein a valve is provided in the main fuel tank to close off the second inlet when the fuel level within the main tank reaches a predetermined level;
- and
- an extension tube for connecting the first filler pipe of the main fuel tank to that of the auxiliary tank, the extension tube having a first connector for sealingly engaging the first filler pipe of the main tank at its lower end and having a third filler pipe at its upper end, the extension tube having a second connector located above the first connector and below the third filler pipe and positioned such that when the main fuel tank is filled below the predetermined level, the flow path of fuel entering the third filler pipe is through the second filler pipe and auxiliary tank into the main fuel tank.
A fuel tank for an agricultural vehicle, comprising a main tank having a first filler pipe and a separate inlet into the tank from that of the first filler pipe, a removable auxiliary tank offset upward from the main fuel tank and having a second filler pipe and an outlet for supplying fuel into the separate inlet of the main tank, the outlet configured to permit direct passage of flow from the second filler pipe into the main fuel tank through the auxiliary tank until a predetermined amount of fuel is present in the main fuel tank;
- and
- an extension tube having a first connector for sealingly engaging the first filler pipe of the main tank at its lower end and having a third filler pipe at its upper end the extension tube having a second connector located above the first connector and below the third filler pipe, the second connector positioned such that fuel entering the third filler pipe will be directed into the second filler pipe of the auxiliary tank, wherein when the main fuel tank is filled below the predetermined amount, the flow path of fuel entering the third filler pipe is into the auxiliary tank through the second filler pipe and then exiting the auxiliary tank through the outlet into the main fuel tank.
