Patent ID: 8773228

Claim:
An actuator which can be actuated electronically from a switched-off position to a switched-on position, comprising: a coil ( 33 ) for generating a magnetic field; a magnetically conductive actuator sleeve ( 37 ) surrounded by said coil ( 33 ); a magnetic flux guiding element ( 53 ) arranged stationary with respect to said actuator sleeve ( 37 ); an armature ( 43 ) mounted for axially sliding movement within said actuator sleeve ( 37 ); said armature having at least two axially extending, parallel, axially offset, magnetic flux conducting profiles ( 99 , 101 ); and said actuator sleeve ( 37 ) comprising at least two magnetic flux conducting parallel passage areas ( 95 , 97 ) of different cross-section and complementary to and facing said magnetic flux conducting profiles of said armature for permitting respective ones of said conducting profiles of said armature ( 43 ) to slide along respective ones of said parallel passage areas; said at least two axially extending, parallel, axially offset, magnetic flux conducting profiles ( 99 , 101 ) contacting said at least two magnetic flux conducting passage areas ( 95 , 97 ) in the switched-off position as well as in the switched-on position.
