<p>A combination valve seat and seal for the inlet passage of a carburetor, the purpose being to provide a resilient seat for a metal inlet valve and also to seal the portion of the housing around the seat so that any accidental or inherent porosity in the carburetor casting will not allow fuel to leak through the inlet valve when it is in closed position. The construction of the insert is such that it seals against the incoming fuel pressure to prevent pressure dislodgement of the seal.</p> |
