Seal assembly for a pressurized fuel feed system for an internal combustion engine

A system, comprising:

• a fuel supply system configured to supply a fuel, wherein the fuel supply system comprises:
• a fuel passage;
• a first sealing surface disposed along the fuel passage;
• a second sealing surface disposed along the fuel passage;
• and
• an o-ring disposed between the first and second sealing surfaces, wherein the o-ring has a first thickness when not compressed between the first and second sealing surfaces, the o-ring has a second thickness when compressed between the first and second sealing surfaces, and the second thickness is at least 30 percent less than the first thickness.

A system, comprising:

• a combustion engine component, comprising:
• a fluid passage;
• a first sealing surface disposed about the fluid passage;
• a second sealing surface disposed about the fluid passage, wherein the first and second sealing surfaces are crosswise to a fluid flow direction through the fluid passage;
• and
• a seal disposed about the fluid passage between the first and second sealing surfaces, wherein the seal has a first thickness when not compressed between the first and second sealing surfaces, the seal has a second thickness when compressed between the first and second sealing surfaces, and the second thickness is at least 30 percent less than the first thickness.

A system, comprising:

• a gas supply system configured to supply a gaseous flow, wherein the gas supply system comprises:
• a gaseous flow passage;
• a first sealing surface disposed about the gaseous flow passage;
• a second sealing surface disposed about the gaseous flow passage, wherein the first and second sealing surfaces are crosswise to a gaseous flow direction through the gaseous flow passage;
• and
• a seal disposed about the gaseous flow passage between the first and second sealing surfaces, wherein the seal has a first thickness when not compressed between the first and second sealing surfaces, seal has a second thickness when compressed between the first and second sealing surfaces, and the second thickness is at least 30 percent less than the first thickness.
