摘要:
In a fuel injection valve, the direct attachment of a protective sleeve to the valve housing has the effect that breathing of the inside of the valve can take place without spray water or other fluids penetrating into the inside of the valve (coil space). The fluid is, rather, held in a space with many passages. Corrosion on the contact pins or on the coil wire is, therefore, ruled out. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
