A fixed magnet (21) and movable magnet (16) are arranged on a frame corresponding to the open state of the control valve arrangement, so that the prevailing magnetic force (R) of the opening movement of the control valve arrangement is acted between fixed magnet and movable magnet against each pole of fixed and movable magnets.
