Parallel Metering Pressure Regulation System for a Thermal Efficient Metering System

摘要

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.

1. A fuel pressure regulation system, comprising:
a supply arrangement for supplying an outlet flow at a first pressure; a primary metering circuit, 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 connected to an outlet of the fuel metering valve; at least one secondary metering circuit, the primary pressure regulator operably connected to the at least one secondary metering circuit to sense a pressure of the at least one secondary metering circuit; 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; and wherein the bypass regulator is operably connected on an outlet side of the fuel metering valve to sense a pressure in the primary metering circuit downstream from the fuel metering valve.
