Abstract

702,797. Fuel injectors. L'ORANGE, R. Nov. 8, 1951 [Nov. 13, 1950], No. 26185/51. Class 7(3) In a fuel injector the fuel is fed to an annular chamber 12 connected to an annular whirl space 13 adjacent the valve seat through inclined passages 14 bored through the valve stem. The valve loading spring 2 exerts its pressure on the needle 3 through an abutment plate 15 having a small contact area with the needle 3 to allow the needle 3 to rotate under the reaction of the fuel flowing through the grooves 14. The needle valve may have a conical, flat, or annular seat.
