ABSTRACT:
A brake booster such as of a tandem type having a center plate disposed within a shell is disclosed. A valve body has a stepped end face, from which a cylindrical portion extends rearwardly. The cylindrical portion extends through a rear power piston and a rear diaphragm while maintaining a hermetic seal therebetween, with a distal end of the cylindrical portion being disposed within a variable pressure chamber of a rear chamber. The internal space of the cylindrical portion defines the rear end of a variable pressure passage. This arrangement allows the rear end of the variable pressure passage (the cylindrical portion) to be disposed in radially overlapping relationship with the rear power piston, thereby allowing the external diameter of the valve body to be reduced. In this manner, the effective area of the front power piston connected to the valve body may be increased as compared with the prior art.
