Abstract
A suppressor for a gaseous fuel system is disclosed. The suppressor may include a cylindrical body having a first end opposite a second end along an axis. A vent opening may be disposed at the second end. A conduit may pass through the first end and may have an inlet disposed outside the cylindrical body and an outlet disposed inside the cylindrical body. The suppressor may include an acoustic core between the outlet of the conduit and the vent opening and configured to reduce a sound level of fluids exiting the conduit. The suppressor may include a thermal mass between the outlet of the conduit and the vent opening, wherein the thermal mass includes fluid channels and is configured to transfer heat energy to fluids exiting the conduit.
Claims20
A suppressor for a gaseous fuel system comprising:
- a cylindrical body having a first end opposite a second end along an axis;
- a vent opening being disposed at the second end;
- and
- a conduit passing through the first end and having an inlet disposed outside the cylindrical body and an outlet disposed inside the cylindrical body,
- an acoustic core between the outlet of the conduit and the vent opening and configured to reduce a sound level of fluids exiting the conduit;
- and
- a thermal mass between the outlet of the conduit and the vent opening, wherein the thermal mass includes fluid channels and is configured to transfer heat energy to fluids exiting the conduit.
A gaseous fuel system comprising:
- a fuel tank;
- an engine;
- a fuel line fluidly connecting the fuel tank and the engine;
- a ventilation line fluidly connecting the fuel line to the atmosphere;
- and
- a suppressor fluidly connected to an end of the ventilation line, the suppressor comprising:
- a cylindrical body having a first end opposite a second end along an axis;
- a vent opening being disposed at the second end;
- a conduit passing through the first end and having an inlet disposed outside the cylindrical body and an outlet disposed inside the cylindrical body,
- an acoustic core between the outlet of the conduit and the vent opening and configured to reduce a sound level of fluids exiting the conduit;
- and
- a thermal mass between the outlet of the conduit and the vent opening, wherein the thermal mass includes fluid channels and is configured to transfer heat energy to fluids exiting the conduit.
A suppressor for a gaseous fuel system comprising:
- a cylindrical body having a first end opposite a second end along an axis;
- a vent opening being disposed at the second end;
- a conduit passing through the first end and having an inlet disposed outside the cylindrical body and an outlet disposed inside the cylindrical body;
- a diffuser connected to the outlet of the conduit;
- an acoustic core located downstream of the diffuser, the acoustic core including:
- a sound-absorbing material;
- one or more acoustic structures configured to promote gas expansion, gas temperature increase, and sound attenuation;
- and
- a thermal mass between the outlet of the conduit and the vent opening, wherein the thermal mass includes fluid channels and is configured to transfer heat energy to fluids exiting the conduit.
