Abstract (en)

[origin: EP1568858A2] The device has a magnetic circuit comprising two non-coplanar ferromagnetic parts (30, 32) each in C form with an open branch (38). The branch provides a space (40) in which a magnetic blade (42) that moves in the space is provided, and the ferromagnetic parts have central branch around which coils (34, 36) are wound. The parts are arranged so that corresponding ends of the open branch are coplanar. An independent claim is also included for an internal combustion engine.
