  • Patent number: 10882065
    Abstract: An agricultural vehicle comprises a left frame and a right frame. A left wheel is rotatable with respect to the left frame and a right wheel is rotatable with respect to the right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. A data processor estimates a reference point on or below the vehicle and an angular orientation or attitude of the beam relative to the reference point based on positions of location-determining receivers associated with the beam. An upper carriage is laterally movable along the beam. A lower carriage is suspended from the upper carriage by a plurality of vertical supports, such that a target lateral position of the upper carriage establishes an actual lateral position of the lower carriage.

  • Patent number: 10851753
    Abstract: A fuel injector is provided which has a valve member, a valve member guide and a spring chamber. Discharge of fuel out of a fuel injector outlet is controlled by movement of the valve member within a bore of the valve member guide. The spring chamber contains a biasing member, which is a compression spring, and which biases the valve member into contact with a valve seat when in a closed configuration. The fuel supply passage is provided, which by-passes the spring chamber, to direct a flow of the fuel to an outlet chamber of the fuel injector, and the cleaning fluid supply passage is provided to supply a pressurized cleaning fluid to a second end of the bore to restrict leakage of the fuel from the outlet chamber towards the second end of the bore along a clearance extending between the valve member and the valve member guide.
