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.

摘要： In order to propose a hollow poppet valve having an excellent, high strength to weight properties by constructing it in order that no influence from welding heat is exerted onto the face, and no stress is concentrated at the welded portion, and a method for manufacturing the same valve, a fillet area 14 opened like a flare is integrally formed at one end of the cylindrical stem portion 12, and a cap is integrally welded to the open edge portion of the fillet area, wherein only the open edge portion of the fillet area 14 is made thicker than the other portions, and the face 15 is formed on the thicker portion 30. Thereby, it is possible to prevent the hardness of the face 15 from being lowered due to the cap welding heat, and stress from being concentrated at the welded portion, whereby the property of high strength to weight can be improved.

摘要： A method of making a valve (62) that has a poppet valve member (100) biased by a spring (110) toward a closed position against a poppet valve seat (90). The spring acts between the poppet valve member and a spring seat (120) and applies a predetermined force to the poppet valve member. The method comprises the steps of providing a valve housing (70) having a chamber (72); inserting into the chamber in sequential order the poppet valve seat (90), the poppet valve member (100), the spring (110), and the spring seat (120); applying a force to the spring seat to compress the spring a predetermined amount; and securing the poppet valve seat and the spring seat to the housing (70) while maintaining the spring compressed the predetermined amount.
