Abstract (en)
A metering pump system includes a variable displacement pump (12) having an inlet (14) and an outlet (16), a flow sensing valve (20) fluidically connected to the outlet of the variable displacement pump (12), and an actuator (30) mechanically coupled to a displacement mechanism (18) of the variable displacement pump (12). The metering pump system also includes an electronic engine controller (50) in communication with the flow sensing valve (20). An electrohydraulic servo valve (60) is electrically connected to the electronic engine controller (50) and hydraulically connected to the actuator (30). The electrohydraulic servo valve (60) is configured to hydraulically drive the actuator (30) to move the displacement mechanism (18) to change displacement of the variable displacement pump (12).
