Braking Servo Booster with Increased Fitting Safety (INCREASED SAFETY OF FITTING)

摘要

The present invention consists of a rigid casing (1) divided into at least two chambers (2, 3) by an elastically deformable diaphragm (4) in which rim (40) Each of the edges forming the overlapping portions 11a, 12a of the complementary curved portions are wrinkled toward each other, and the braking force for traction of the rim of the diaphragm The present invention relates to an air pressure servo.;According to the invention, the overlapping portion (11a) formed in at least one component (11) of the casing is such that the rim of the diaphragm is pushed by the overlapping portion of the components of the casing And the diaphragm is more effectively retained.
