Abstract

1372207 I C engine fuel injectors ROBERT BOSCH GmbH 17 Dec 1971 [18 Dec 1970] 58610/71 Heading FIB [Also in Division H1] The valve member 10 mounted on the armature 5 of an electromagnet is located co-axially of the valve seat 13 by two spaced diaphragms 20, 21 clamped at their outer edges in the injector housing 1. The threaded shank 25 of the member 10 is secured in the armature 5 with adhesive 37 and the armature comprises a soft iron part 28 and aluminium parts 24 and 27. With the coil 8 de-energized the armature part 28 is spaced approximately 0À06 mm from the soft iron ring 32 under the bias of the spring 15.
