摘要

The diesel engine fuel injector consists of a hollow injector body (39) fitted with a plunger (41) located within the body. A movable coupling (45) is positioned within the body of the injector, alongside the fuel dispensing nozzle. A variable rate return spring (36) is placed in between the injector body and the coupling, so that any movement from the coupling compresses spring.
