Abstract
A fuel system, such as for use in an aircraft, comprises a main pump, a servo pump, a modulating valve, a shut-off valve, an actuator and a pump sharing valve. The main pump and the servo pump receive fuel from a source. The metering valve receives main flow from the main pump. The shut-off valve receives fuel flow from the metering valve. The actuator receives fuel flow from the servo pump. The pump sharing valve receives circulating flow from the servo pump and alternatively directs shared flow to the main flow or an inlet of the servo pump. The pump sharing valve also sends main pump flow to supplement the servo pump during shutdown conditions.
