ABSTRACT:
A vacuum servo unit includes a movable power piston having a base portion and a cylindrical portion whose output side end portion is connected to the input side end portion of the base portion. The base portion has an annular first projection projecting into the inside of the cylindrical portion and a second projection projecting into the inside of the cylindrical portion. the second projection divides the space surrounded by the annular first projection into a first space and a second space. A vacuum path communicates the constant pressure chamber with the first space, and an air path communicates the variable pressure chamber with the second path. Thus, the area of the cross-section of the second space in a plane perpendicular to the axis of the movable power piston can be enlarged so that atmospheric air can smoothly flow into the variable pressure chamber.
