发明名称 VACUUM BRAKE BOOSTER FOR AUTOMOBILE
摘要 In prior art vacuum brake boosters the partition wall is supported by a control hub. The boosting force is transmitted through the hub to a force transmitting serving to actuate the master cylinder. According to the present invention the partition wall includes a central sleeve of a stepped configuration which serves to transmit the boosting force without loading the hub. As a result the hub can be produced from a thermoplastic material of just sufficient strength to meet the reduced force transmitting requirements and which is easier to mold.
