Abstract (en)

An electromagnetic valve actuator (10) for actuating movement of a valve (12) in a vehicle engine is disclosed. The actuator (10) includes a valve assembly operatively connected to the valve for movement therewith. The valve assembly includes a shaft (14) connected to the valve (12), two armature plates (16,18) operatively associated with the shaft (14) each armature plate (16,18) having a permanent magnet as an integral part. An electromagnetic coil (24) is positioned between the two armature plates (16,18) for electromagnetically pushing and pulling the armature plates (16,18) and two springs (26,28) are engaged with the two armature plates (16,18) for biasing them in opposing directions. The permanent magnets are used to assist the electromagnetic coil (24) in holding the valve (12) in a desired position to reduce power consumption. <IMAGE>
