Storage device for intermediately storing returned brake fluid from wheel brake cylinders in hydraulic assembly of passenger car brake system, has sealing ring fixedly held at storage piston by deformation, where piston is produced as blank

摘要

The device has a sealing ring (36) i.e. O-ring, arranged at a storage piston. The sealing ring is fixedly held at the storage piston by deformation, where the storage piston is produced as a blank (38). The blank is designed as an injection molded part. The blank is provided with axially aligned deformation geometry (50) for forming the deformation. The blank is designed in a round shape. The deformation geometry is extendingly designed over an entire circumference of the blank. The deformation geometry is designed at a bottom (32) of the blank.
