Abstract

403,264. Liquid-fuel injectors. BOSCH AKT.-GES., R., 4, Militõrstrasse, Stuttgart, Germany. April 5, 1933, No. 10159. Convention date, April 21, 1932. [Class 7 (iii).] In a liquid-fuel injector having a piston raised by the fuel pressure, and a separate needle valve, the valve has differential areas on which the fuel pressure acts to couple the needle and the piston during injection. As shown in Fig. 1, fuel is supplied by a pump through a channel n to a chamber k, where it acts upon a collar f on the needle valve e and maintains the collar in contact with the edge of the piston g. The valve has an extension h of larger diameter, which is guided in a bore i in the piston, and any fuel leakage passes through a bore u in the piston and is discharged through a passage t. An adjustable stop r limits the lift of the valve. In a modified construction, a pin nozzle is used and the collar f is dispensed with ; the fuel pressure maintains the enlarged extension h in contact with the bottom of the bore i , and a grooved collar is provided near the valve seat to guide the valve e.
