FUEL-INJECTION METERING DEVICE, FUEL-INJECTION NOZZLE, MOULD FOR PRODUCING A FUEL-INJECTION METERING DEVICE AND METHOD FOR PRODUCING A FUEL-INJECTION METERING DEVICE

摘要

The present application concerns a fuel-injection metering device for a motor vehicle. The fuel-injection device include a main body with at least one through-hole, whereby the main body forms a valve seat on its inner face that is provided to interact with a valve body, whereby the inner face of the main body is electrochemically machined. The application also concerns a mould, a production method, and a fuel-injection nozzle.
