Abstract
395,175. Fuel - injection pumps. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. Aug. 9, 1932, No. 22266. Convention date, Sept. 14, 1931. [Class 102 (i).] In a fuel-ignition pump of the type in which the injection is effected by means of an accumulator plunger 13 loaded by an adjustable spring 14, the pump plunger 8 is connected to a piston 7, which is operated against the action of a spring 11 by the pressure in the engine cylinder 6, admitted to the piston 7 by a pipe 5. Injection takes place through a passage 18 and a groove 16 in the plunger 8 and a passage 10 and nozzle 3. The plunger is rotatable by means of a rack 20 and pinion 19, and is formed with an inclined edge 12, which controls the suction passage 9. Alternatively the amount of the charge may be controlled by a valve independent of the pump plunger, or by limiting the stroke of the pump plunger by means of an adjustable stop. The accumulator plunger may be loaded by the pressure in the engine cylinder. Specification 375,151 is referred to.
