Abstract

A low-pressure casing for a brake booster for automotive vehicles comprises two casing shells which are sealingly interconnected and include a reinforcement plate at the inner surface of the casing end wall of each casing shell. The reinforcement plate is fastened to the master brake cylinder or to the automotive vehicle by means of fastening bolts. The section of the casing end wall which lies radially outside the reinforcement plate is of truncated-cone-shaped construction and merges into a cylindrical section of the casing. Inserted in the inner of the casing at the transition from the truncated-cone-shaped section into the cylindrical section is a prop ring which is via webs formed integrally with the reinforcement plate.
