ABSTRACT:
The seal assembly comprises providing a fuel conduit having a fluid flow passage therethrough for conveyance of a pressurized fuel-containing gas in a general fluid-flow direction with a first sealing surface disposed on the fuel conduit. A second sealing surface engages with the first sealing surface, such as to provide a fluid-tight connection preventing pressurized gas from leaving the fluid flow passage. The said first and second sealing surfaces are substantially perpendicular to the general fluid-flow direction. An o-ring is 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. Preferably the o-ring is subjected to a squeeze of at least 40%, more preferably 50%, when the first and second sealing surfaces are coupled together. The sealing arrangement is most advantageously applied to throttle assemblies and the like, in particular for use with low-speed, gaseous fueled engines.
