Abstract
The pneumatic booster of the vacuum type comprises mainly a housing (12) divided into two chambers (7, 8) by a movable wall structure (6), constructed of a substantially radial plate (9) and a flexible diaphragm (10) secured by its outer peripheral edge to the housing (12), and forming a flange (11) in the space between the plate (9) and the housing (12). The plate is centrally integral with a hub structure housing, a distribution valve device and linked to a control member and to a controlled member, each by a swivel connection. The plate (9) has at its outer edge an extension (13) cooperating in a non-leaktight manner with the internal wall of the housing (12) in order to ensure axial guidance of the movable wall (6) inside the housing (12).
