Abstract
A very fast electromagnetic fuel injector of cartridge design for the injection of fuel into the intake manifold of an internal combustion motor. The magnetic pole of the valve is mounted on a non-magnetizable casing which is solidly connected to a valve seat. This casing, together with the armature, the magnetic pole, and the valve seat, form a cartridge which can be manufactured independent from the other valve components. The cartridge is built into a valve housing which largely consists of plastic material. The fuel injector is therefore inexpensive to manufacture. In addition, the valve can be provided with a monostable polarized magnetic circuit.
