ABSTRACT:
A fuel injection valve for an engine comprises a tubular housing having a central throughway. An axially directed valve seat defines an outlet from the throughway. At least one housing fuel inlet communicates the exterior of the housing with the throughway outwardly of the seat. A sealing section outwardly of the housing fuel inlet includes an internal annular enlargement in the central throughway. A housing buffer inlet communicates the exterior of the housing with the enlargement. An inert, nonflammable buffer gas is injected through the housing buffer inlet. A valve stem is mounted for reciprocation in the throughway and has a valve element for cooperation with the seat. First and second annular housing seals are disposed between the valve stem and the housing, respectively inwardly and outwardly of the downstream end of the housing buffer inlet.
