Patent number: 6928918Abstract: A pneumatic brake booster comprising an envelope of longitudinal axis formed of a dish having a rim and a lid. The envelope defines an interior volume that is divided into a variable-pressure work chamber and a low-pressure chamber by a skirt. The skirt is mounted to sealingly slide along the longitudinal axis of the envelope. The skirt has a central orifice with a pneumatic piston sealingly mounted therein. The sealing between the variable-pressure work chamber and the low-pressure chamber is achieved by a first sealing member arranged between a radially internal first end of the skid and a radially external end of the piston and a second sealing member arranged at a radially external second end of the skid and an internal surface of the rim. The skid provides sealing between the radially external first end of the skirt and the radially internal second end of the skirt.Type: GrantFiled: March 21, 2003Date of Patent: August 16, 2005Assignee: Robert Bosch GmbHInventors: Ulysse Verbo, Jean-Pierre Michon
