Abstract
A fuel injection system is described, and which has an upstream portion and a downstream portion. The upstream portion includes a source of fuel, the fuel inlet of a fuel injection servo or flow regulator, and a first fuel flow line connected in fuel flowing relation relative to the source of fuel and to the fuel inlet of the fuel injection servo. The downstream portion includes a flow divider, at least one fuel outlet of the fuel injection servo, and a second fuel flow line connected in fuel flowing relation relative to the flow divider and the fuel outlet of the fuel injection servo. A fuel accumulator pressure damper is mounted in fuel flowing relation relative to the downstream portion of the fuel injection system so as to substantially reduce standing waves in the fuel injection system.
Claims14
A fuel injection system, comprising:
- a fuel injection servo with a fuel inlet and at least one fuel outlet;
- an upstream portion of the fuel injection system, comprising a source of fuel;
- the fuel inlet of the fuel injection servo;
- and a first fuel flow line connected in fuel flowing relation relative to the source of fuel and to the fuel inlet of the fuel injection servo;
- a downstream portion of the fuel injection system, comprising a flow divider;
- at least one fuel outlet of the fuel injection servo;
- and a second fuel flow line connected in fuel flowing relation relative to the flow divider and the at least one fuel outlet of the fuel injection servo;
- and
- a fuel accumulator mounted in fuel flowing relation relative to the downstream portion of the fuel injection system;
- wherein the fuel accumulator comprises a vessel fabricated from a pressure compliant material received within containment housing.
A fuel injection system for an aircraft engine, comprising:
- a source of fuel;
- a fuel injection servo with a fuel inlet, and wherein the source of fuel is connected in fuel supplying relation relative to the fuel inlet of the fuel injection servo;
- and
- a fuel accumulator mounted downstream of the fuel inlet of the fuel injection servo, and wherein the fuel accumulator comprises a vessel fabricated from a pressure compliant material which substantially reduces standing waves in the fuel injection system.
