ABSTRACT:
An improved diaphragm is disclosed which partitions the interior of a shell of a brake booster into a constant pressure chamber and a variable pressure chamber. The diaphragm includes a bead which extends around its inner periphery, and which is formed with a lip extending from the side of the constant pressure chamber to the side of the variable pressure chamber. The lip is held in close contact with the outer peripheral surface of a valve body. The lip is capable of an elastic deformation in a flexible manner, whereby a good seal against the outer peripheral surface of the valve body is maintained.
