Servo brake unit for brake systems of motor vehicles has multi-sectional support component between pneumatic chambers and provided with cover formed as tube section and sealed at one end at least

摘要

The rod-form support component(20) located between the half-shells of the casing(2) is constructed multi-sectional at least in the radial direction. The support component has a cover which has a diameter which coincides with the second diameter of the passage(15) connecting the two pneumatic chambers(10,13). The cover is in the form of a tube section which extends approximately over the whole of the support component and which at least at one end is sealed and connected to the support component.
