Abstract (en)

[origin: WO03019582A1] The invention concerns an electromagnetic actuator comprising a stator structure (2) consisting of two ferromagnetic circuits (3, 4) provided with at least an electric excitation coil (5, 5A; 6, 6A) and between which is mounted mobile between two stable end-of-travel positions (8, 9) and countering the action of elastic return means (10), an armature (7) made of soft ferromagnetic material symmetrically connected to a load to be controlled, the armature (7) and the stator structure (2) being symmetrical relative to the axis (12) of rotation of the armature (7). The invention is characterised in that each ferromagnetic circuit (3, 4) comprises four stator poles with which are urged to co-operate in pairs the armature (7) in one or the other of its stable end-of-travel positions. The invention is particularly applicable for controlling combustion air intake duct valve of internal combustion engines.
