Abstract
A brake booster includes a center plate disposed within a shell. A seal member is provided to interrupt a communication between a variable and a constant pressure chamber which are located across the center plate. The seal member is formed with a lip, acting as a check valve which releases to the variale pressure chamber any pressure developed in the constant pressure chamber which is to be sealed by the seal member and which rises above the pressure in the variable pressure chamber.
