Title:
HYDROMECHANICAL PRESSURE COMPENSATION CONTROL OF A VARIABLE DISPLACEMENT PUMP IN A CENTRIFUGAL PUMPING AND METERING SYSTEM AND ASSOCIATED METHOD
Document Type and Number:
WIPO Patent Application WO/2013/166108
Kind Code:
A3
Abstract:
A pump assembly includes a pump unit having a centrifugal pump and a variable pump supplying pressurized flow. A fuel control assembly receives flow from the pump unit and includes at least one metering valve and at least one throttling valve. A control for the variable pump receives first and second pressure signals indicative of a pressure differential across the throttling valve, or across the metering valve/throttling valve combination, for altering operation of the variable pump in response to the pressure differential.
