ABSTRACT:
The pre-assembled two-stage reaction device for a vacuum brake booster includes reaction levers which are in engagement with the booster movable wall at a first location and with the master cylinder push rod and a reaction plate connected thereto at a second location, with the first location being arranged radially farther out than the second location. The reaction levers are acted upon by a cup spring at a third location, with the cup spring being positioned on the side of the reaction levers adjacent a vacuum chamber and with the third location having a greater radius than the first location. A spring plate is arranged between the cup spring and the reaction levers whose circumferential collar is provided with flattened portions for the reaction levers on the side adjacent the reaction levers. To create a two-stage reaction device which can be pre-assembled and can also be employed in boosters having control housings made of thermoplastic material, there is arranged a supporting ring with two inward supporting edges upon which the reaction levers abut whose inner ends are tiltable about the supporting edges in the direction of the control valve, and with the reaction levers, the push rod with the reaction plate, the spring plate and the cup spring being retained together by the supporting ring on the one side and by a circular guide element connected thereto on the other side.
