摘要：
A direct metering fuel supply system includes a fuel pump, a burn flow fuel line, a servo flow fuel line, and a servo regulator. The fuel pump is adapted receive pump commands representative of a commanded fuel flow rate and is configured, in response to the pump commands, to discharge fuel at the commanded fuel flow rate. The burn flow fuel line is in fluid communication with the pump to receive a first portion of the fuel discharged therefrom. The servo flow fuel line is in fluid communication with the pump to receive a second portion of the fuel discharged therefrom. The servo regulator is mounted on the servo flow fuel line and configured to maintain fuel flow rate in the servo flow fuel line at a substantially constant fuel flow rate regardless of fuel flow rate in the burn flow fuel line.
