| 摘要 |
The invention relates to an electromagnetic injection valve, for controlling a fuel amount to be injected into an internal combustion engine, comprising a valve body which may be displaced by an electromagnetic coil system, co-operating with a magnet armature of the electromagnetic coil system. According to the invention, the electromagnet coil system comprises at least two concentrically arranged coils (32-1, 32-2), said coils (32-1, 32-2) are arranged in a magnetic circuit, such that a first pole body (42-2) is arranged between two adjacent coils and a second pole body (42-1, 42-3) is arranged adjacent to the inner and outer coil (32-1, 32-2), whereby the first and second pole bodies (42-1, 42-2, 42-3) are components of the magnetic circuit in the electromagnetic coil system and each adjacent coil (32-1, 32-2) may be activated in the opposing sense to each other, by a common activation current (40).
