Abstract
A brake power booster for automotive vehicles has a control valve which is operable by a solenoid irrespective of the driver's wish. In order to adapt the force-travel characteristic curve of the solenoid to the consumer characteristic curve of the control valve exhibiting a drop in force, the present invention discloses an armature having two parts which are movable relative to each other and interact with stops that are axially offset in the housing of the solenoid in the actuating direction of the latter.
