Abstract:
1. A fuel supply system for supplying a pressurized gaseous fuel to a low speed internal combustion engine comprising: a fuel conduit having a fluid flow passage therethrough for conveyance of a pressurized fuel-containing gas in a general fluid-flow direction; a first sealing surface disposed on the fuel conduit; a second sealing surface engaged with and parallel to the first sealing surface, to provide a fluid-tight connection preventing pressurized gas from leaving the fluid flow passage; said first and second sealing surfaces are substantially perpendicular to the general fluid-flow direction; an o-ring disposed between the first sealing surface and second sealing surface, the o-ring being compressed by the first and second sealing surfaces to form said fluid-tight connection; wherein the o-ring when acted upon by the first and second sealing surfaces has a thickness that is at least 30% less than the thickness of the o-ring when not acted upon by the first and second sealing surfaces.
