Abstract
A fuel pressure regulation system is provided. The fuel pressure regulation system includes a supply arrangement for supplying an outlet flow. A primary metering circuit is provided, an inlet of which receives a first portion of the outlet flow of the supply arrangement, the primary metering circuit comprising a fuel metering valve and a primary pressure regulator. The primary pressure regulator is connected to an outlet of the fuel metering valve. The system also includes at least one secondary metering circuit. The primary pressure regulator is operably connected to the at least one secondary metering circuit to sense a pressure of the at least one secondary metering circuit. The system also includes a bypass regulator connected in parallel with the primary metering circuit and the least one secondary metering circuit such that an inlet of the bypass regulator receives a second portion of the outlet flow of the supply arrangement.
