Abstract: A drive system for a fluid displacement pump includes an electric motor, a drive coupled to the rotor at a first end of the electric motor, a pump including a fluid displacement member mechanically coupled to the drive, and a controller configured to control a level of power to the electric motor based on a pressure setting set by a user. The electric motor includes a stator and a rotor disposed on an axis. The drive coupled to the rotor converts the rotational output to a linear, reciprocating input to power a pump.

Abstract: A power controller monitors and controls supply of AC power to a load. A power supply derives DC power supply voltages from the input AC power. The power supply includes power dissipation circuit that dissipates excess power as a function of one of the supply voltages. A voltage sensing circuit provides a voltage sense signal that is a function of the voltage of the input AC power. A digital processor controls a switch that connects a load to the AC power based upon the voltage sensed signal.

Abstract: The present application discloses a method for measuring pressurized liquid fuel level in a fuel tank used on a vehicle comprising measuring the pressure of the fuel to generate a pressure signal and measuring the temperature of the fuel to generate a temperature signal. A fuel level signal is determined from the pressure signal and the temperature signal and changes in the fuel level signal are determined over time. A first point of the fuel level signal indicating approaching emptying of the tank is identified when changes in the fuel level signal exceed a given value and the approaching emptying of the tank is signaled to an operator of the vehicle in response to identifying the first point.

Abstract: A cooling assembly is provided for use in a work vehicle. The cooling assembly may comprise a heat exchanger for transferring energy in the form of heat from a coolant fluid to air passing through the heat exchanger, filter structure positioned adjacent a first side of the heat exchanger to filter the air before the air passes through the heat exchanger, and a fan shroud positioned adjacent a second side of the heat exchanger.

Abstract: A work vehicle is provided comprising: a main frame including an engine compartment; an engine located in the engine compartment; and a cooling system comprising a rotating fan apparatus and a cooling assembly. The cooling assembly may comprise a heat exchanger for transferring energy in the form of heat from a coolant fluid to air and a filter apparatus positioned adjacent an engine-compartment side of the heat exchanger. The air may be moved through the heat exchanger by the fan apparatus. The filter apparatus may filter the air before the air passes through the heat exchanger. The filter apparatus may comprise filter structure and a suction device for removing debris from the filter structure. The suction device preferably expels the debris outside of the engine compartment.
