Abstract:
Embodiments include a modular fuel pump apparatus for an aircraft refueling chassis and related devices, systems and methods. In one exemplary embodiment, a pump module includes a hydraulic motor driven by a hydraulic pump connected to a chassis motor. A chassis engine is operated at a substantially constant RPM, which causes the hydraulic pump to output hydraulic fluid to the pump module at a substantially constant hydraulic pressure. The speed of the hydraulic motor can be varied by a proportional flow control valve disposed between the hydraulic pump and the hydraulic motor, thereby varying the speed of the fuel pump and the flow rate of the fuel. A controller is configured to operate the pressure control valve such that the flow of the fuel is maintained at a predetermined flow rate.

Claim (Index 1):
A pump module for a fuel delivery chassis, comprising:\n a proportional flow control valve configured to receive hydraulic fluid at a first hydraulic fluid flow rate from a hydraulic pump driven by a vehicle engine, the proportional flow control valve configured to allow at least a portion of the hydraulic fluid to pass through at a second hydraulic fluid flow rate; a hydraulic motor configured to receive and be driven by the hydraulic fluid passing through the proportional flow control valve at the second hydraulic fluid flow rate, the hydraulic motor configured to rotate at a rotational rate corresponding to the second hydraulic fluid flow rate; a fuel pump configured to be driven by the hydraulic motor, the fuel pump configured to pump fuel from a fuel storage receptacle to at least one fuel delivery hose assembly at a fuel flow rate corresponding to the rotational rate of the hydraulic motor; and a controller configured to control the proportional flow control valve to adjust the second hydraulic fluid flow rate to maintain the fuel flow rate within a predetermined flow rate range.
