Fuel Injector

The body of the injector valve (1) may be at a slight angle to the injector tip. A metal ring (33) surrounds a narrow angled portion of the injector valve body and pushes an inwardly-projecting flange (25) at the narrow end of the funnel-shaped seal into a semicircular-section groove (26) in the injector valve body. The broad end of the funnel fits in a circular bore in the wall of the engine induction manifold (30). The spray of injected fuel passes through an L-section ring (31,32) in the broad end of the funnel-shaped seal.
