Abstract

539,856. Liquid-fuel injectors. STEVENS, A. H. (Ex-Cell-0 Corporation). Feb. 19, 1940, No. 3144. [Class 7 (iii)] A fuel-injection nozzle includes a body 3, Fig. 4, having an outlet passage 6, a spring- seated valve 20 for controlling the admission of fuel to the passage 6, and a pintle 15 carried by the valve, an annular restricted outlet between the pintle and the wall of the passage 6 being open in all positions of the pintle, which moves outwards on the opening of the valve to increase the area of the annular fuel outlet. As shown, the body 3 has a flange 7 held against the flange 49 of a housing 46, Fig. 1, by a filter holder 55 engaged by a nut 63, to which an inlet fitting 68 is clamped by a bolt 69. The valve 20, Fig. 4. is held against a spherical seal 14 in the flange of a tubular member 8 by a spring 27 surrounding the valve stem 30 and bearing against a hanger 29 engaging a head 31 on the valve stem. The valve and pintle, shown enlarged in Fig. 7, have a narrow cylindrical area 16 nearly closing the outlet passage 6, conical faces 17, 18, an annular groove 26, and a peripheral rib 22 near the valve face 20. The rib 22 co-acts with a shoulder 24 in a counterbore 21 to limit the opening movement of the valve and pintle, and spaced longitudinal passages 25 admit the fuel from the valve to the annular outlet around the pintle. Suitable dimensions for the pintle, valve &c. are specified. In a modification, Fig. 8, a tubular bushing 38 is fitted in a counterbore 37 in the end wall of the body 3a, and the bore of the bushing is counterbored to form a valve chamber 21a and a stop shoulder 24a. Longitudinal passages 25a in the bushing 38 lead to the distribution chamber 26a around the conical face 17a of the pintle. A sleeve 40 within the valve seat member 8a serves as a stop for the hanger 29a.
