Abstract
An apparatus, system, and method of damping pressure pulsations and attenuating noise transmission in a fuel supply system. The apparatus includes a first end in fluid communication with a fuel supply line, a second end in fluid communication with a manifold, and a body that couples in fluid communication the first and second ends. The first end is adapted to receive fuel from a pump. The second end is adapted to supply the fuel to a plurality of nozzles in individual fluid communication with the manifold. And the body includes a tube that is arranged in a helix around a central axis.

An apparatus damping pressure pulsations and attenuating noise transmission in a fluid supply system, the apparatus comprising:
- a first end in fluid communication with a fluid supply line, the first end is adapted to receive fluid from a pump;
- a second end in fluid communication with a manifold, the second end is adapted to supply the fluid to a plurality of nozzles in individual fluid communication with the manifold;
- and
- a body coupling in fluid communication the first and second ends, the body including a tube arranged in a helix around a central axis, the body including a first portion extending along a first axis from the helix to the first end, and including a second portion extending along a second axis from the helix to the second end.
A system for delivering fuel to an internal combustion engine, the system comprising:
- a tank storing fuel at a first pressure;
- a fuel injector dispensing the fuel, the fuel is supplied to the fuel injector at a second pressure;
- an apparatus in fluid communication between the tank and the fuel injector, the apparatus including:
- a first end in fluid communication with the tank;
- a second end in fluid communication with the fuel injector;
- and
- a body coupling in fluid communication the first and second ends, the body including a tube arranged in a helix around a central axis;
- and
- wherein the apparatus damps pressure pulsations and attenuates noise transmission due to variations in the second pressure.
A system for delivering fuel to an internal combustion engine, the system comprising:
- a tank storing fuel;
- a fuel injector dispensing the fuel;
- an apparatus in fluid communication between the tank and the fuel injector, the apparatus providing a helical fuel flow path and reducing pressure pulsations to an approximate range of ±10.0 kilopascals.
