Abstract

1322793 Electromagnetic I.C. engine fuel injectors SOC DES PROCEDES MODERNES D'INJECTION 7 July 1970 [1 Aug 1969] 32974/70 Heading F1B At least part of the passage 13a leading from the injector inlet to the injector valve 11 has a cross-section of substantially 2 mm diameter. The passage may be circular and may be formed by a conduit (13), Fig. 1 (not shown), extending adjacent the injector housing 1. The injector nozzle 9 is spaced from the solenoid core 5 by a bronze ring 7.
