Abstract

The present invention relates to a brake booster device for a vehicle brake system comprising a force input element, a control valve arrangement actuable via the force input element, a chamber arrangement disposed in a housing and comprising a vacuum chamber and a working chamber, which is separated from the vacuum chamber by a movable wall and connectable selectively to a vacuum source or the atmosphere, and a force output element, wherein the movable wall is biased into a normal position by a resetting spring accommodated at least partially in the housing and wherein the housing is penetrated by at least one fastening bolt. In this case, it is provided that at least one damping element acts for the purpose of vibration damping on the resetting spring, wherein the at least one damping element is mounted on the at least one fastening bolt.
