  • Patent number: 11493106
    Abstract: Embodiments of a hydraulic bump stop assembly may include a telescoping hydraulic cylinder containing hydraulic fluid. The telescoping cylinder may be located on a vehicle shock. Components of the shock may engage and compress the telescoping cylinder during the final stages of compression of the shock to prevent the shock from bottoming out. The telescoping cylinder has damping properties during compression and expansion due to hydraulic fluid being forced through orifices of one or more hydraulic fluid lines to and from a reservoir. Damping ratios may be adjusted by adjusting the size of the orifices. In some embodiments, the damping ratios may be adjusted remotely, such as from the driver compartment of the vehicle.
