Abstract
A brake booster includes a solenoid valve which enables the opening or closing of a passage which provides a communication between a constant and a variable pressure chamber through a valve mechanism. The invention utilizes an empty space left within the constant pressure chamber for disposing a solenoid valve therein. The solenoid valve is mounted on a valve body in a manner to utilize the entry space efficiently to allow the solenoid valve to be mounted on the valve body without increasing the axial size of the brake booster.
