摘要

The device has a control valve arrangement (14) that is operated by a force input unit (12). A chamber arrangement (24) is arranged in a housing (16) and includes a vacuum chamber (20) and an operating chamber (22) that is connected with a vacuum pressure or the atmosphere and that is separated over a movable barrier (18). The barrier is pre-stressed by a reset spring (38) that is accommodated in the housing. Damping units (48, 50) are engaged at the reset spring, where the damping units are attached at a clamping bolt. An independent claim is also included for damping units for a brake force boosting device.
