  • Patent number: 6928918
    Abstract: 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.

  • Patent number: 6918249
    Abstract: A brake booster comprising an envelope (2) having a longitudinal axis (X) formed of a first (4) and of a second (6) shell to define an interior volume divided by moving a skirt into a low-pressure first chamber and a variable-pressure second chamber. A three-way valve (12) actuated by a control rod places the front chamber and the rear chamber in communication at rest and during a braking phase interrupts the communication between the front chamber and the rear chamber and thereafter allows communication of pneumatic fluid at high pressure to the rear chamber. The booster is attached to the master cylinder by a clip-fastening arrangement wherein tabs (52) that radially extend from a sleeve tube (48) are plastically deformable in the radial direction on enter into a passage (54) in a flange (56) of the master cylinder and returning to the initial position when the attachment operation is complete.
