Abstract

1,197,738. Valves. ROBERT BOSCH G.m.b.H. 19 Oct., 1967 [20 Oct., 1966], No. 47608/67. Heading F2V. [Also in Division F1] A solenoid actuated fuel injection valve comprises an armature 7 with a pin 8 secured thereto so as to be reciprocable to actuate a valve needle 13, the pin 8 and needle 13 being separate and having a gap A therebetween. The needle 13 is mounted in a body part 10 which is screwthreaded into the main body 1, so that the gap A can be adjusted. Once adjusted, the part 10 is locked into the body 1 by an adhesive placed in bores 18. A part 6 is screw-threaded into an inlet connection 4 to act as an adjustable stop for the armature 7. The fuel enters the valve at 4, and passes through the valve body to a chamber 10b, and through passages 23 in a nozzle body 12, Fig. 2, to be metered by a gap 25 between the nozzle body bore and an enlargement 13c of the needle 13. In Fig. 3, not shown, the fuel is metered by tangentially arranged passages (27) in the nozzle body.
