摘要:
An engine fuel injector body is assembled using a furnace brazing method to provide structural and hermetic internal joints at interior locations with minimum size and processing. The method of assembling an injector with such an internal hermetic and structural joint may include the steps of providing an annular body member with an annular inner recess having an inner cylindrical surface, forming an annular end recess adjoining the cylindrical surface, fitting a tubular member into the inner recess of the body member with an outer surface of the tubular member engaging the cylindrical surface of the inner recess, placing a brazing ring in the end recess of the body member adjacent the tubular member, and furnace brazing the members together to form the internal hermetic and structural joint. Additional joints may be joined during the same brazing step.
