Abstract
A fuel system for a work vehicle such as a tractor includes a pair of fuel tanks located on either side of the vehicle that are connected by a cross feed fuel line. The fuel line permits fuel to flow from both tanks to a common fuel suction line, which, in turn, feeds the vehicle's engine with fuel. The fuel line includes a check valve that prevents the free flow of fluid through the cross feed line when the vehicle is driven across a slope. The check valve is disposed to prevent liquid fuel from flowing away from a fuel suction line and starving the suction line for fuel.
Claims18
A fuel tank system for a work vehicle, comprising:
- a first fuel tank having a first fuel outlet disposed on a lower portion thereof;
- a second fuel tank having a second fuel outlet disposed on a lower portion thereof;
- a cross feed line having an inner diameter and coupled to and between the first and second outlets;
- and
- a check valve disposed in the cross feed line to block fuel from flowing through the cross feed line from the second tank to the first tank.
A flapper valve for a fuel tank system comprising:
- a polymeric annulus having a width in an axial direction greater than a thickness in a radial direction;
- and
- a generally planar valve element including an upper portion fixed to the annulus and a lower portion configured to pivot with respect to the annulus, thereby providing a fluid passageway between the annulus and the valve element.
