Electromagnetic actuator for gas shuttle valve actuation in internal combustion engine, includes coils wound on either sides of permanent magnet, to produce overlapping fields that is parallel to the magnet axis

摘要

The coils (12,13) are wound in the internal toothed area of a housing, on either sides of a permanent magnet (1) supported inside the housing. The coils produce overlapping magnetic fields that is parallel to the magnet axis, so that the magnet and a valve disk at the end of the magnet displace.
