Abstract

A metal cup accommodating a reaction disc and the end of a push rod is fixed with respect to a control valve housing of a vacuum brake power booster. The manner of fixation is of simple design, allowing the parts to be manufactured at low cost and offering ease of mounting. According to the invention a metal cup is supported in axial direction at the front side of the control valve housing and is retained by a retaining clip in a positive locking fit with the control valve housing.
