Vacuum brake booster

摘要

The brake booster comprises two booster units in a tandem arrangement each having a movable wall. A stationary partition is provided between the two movable walls. In order to increase the axial stiffness of the booster casing, the partition is provided with bolt projections extending in both directions therefrom and are rigidly connected to the appropriate end walls of the casing. The ends of the bolt projections at the end walls form anchor means for connecting the booster to a master brake cylinder and to a supporting surface of a motor vehicle.
