Abstract

A fuel injector, e.g., for fuel-injection systems of internal combustion engines in motor vehicles, includes a valve housing including a sleeve-shaped housing section; and a solenoid, situated on the housing section, having a coil brace, magnetic coil and magnetic cup. To protect the magnetic coil from salt fog that arises under specific environmental conditions and penetrates along the contact areas of solenoid and housing section, the coil brace with wound magnetic coil is completely enclosed on all sides by a one-piece plastic coat.
