  • Power steering system
    Patent number: 6513618
    Abstract: A power steering system for a motor vehicle comprising a hydraulic reaction device (11) by which reaction power is generated on the steering column of the vehicle, depending on the speed thereof. According to the invention, a accumulator (14) is provided on the line (13) connecting the reaction device (11). Said accumulator serves as a low-pass filter and decouples the reaction device from oscillations in pressure due to uneven road surfaces.
