ABSTRACT:
A brake booster of tandem type includes a valve body, a rear power piston, a front power piston and a centerbody slidably extending through a centerplate which is centrally disposed within a shell, all of which are integrally connected together by utilizing a hub. An end of the hub located adjacent to the valve body is formed with an engaging portion which extends radially outward, while the shank portion of the valve body is formed with an axial groove which permits the engaging portion to pass there through and is also formed with an engaging recess circumferentially displaced from the axial groove and receiving the engaging portion. The engagement between the engaging portion and the engaging recess allows the hub to be assembled with the valve body while preventing the withdrawal of the hub forwardly from the valve body and also preventing the relative rotation therebetween, all with a greatly simplified construction.
