Fuel injector, e.g. for a motor vehicle, has an injector body, a jet body and an actuator for operating a needle-shaped injection valve element

摘要

A first buncher space (72) activates an injection valve element (92). An actuator (20) fits in an injector body (12) in a pressure chamber (18) affected by systems pressure. A fuel injector (10) has a pressure intensifier (26). So as to reverse the direction of force/effect, the actuator is assigned a primary (28)/secondary (30) piston system.
