  • Publication number: 20060278483
    Abstract: This invention relates to a type of adjustable damping shock absorber, comprising a reservoir, piston rods, and piston bodies. Said reservoir has an upper sealing cap with a through hole. The piston rod is placed in the through hole using a sealing ring. The special characteristics are: said piston body comprises an upper piston body and a lower piston body. A piston rod is connected to the upper piston body and a piston spinning rod is connected to the lower piston body. At the corresponding positions of the upper piston body and the lower piston body, there are passage holes for the passage of a liquid of choice to achieve damping. The lower piston body is connected to a power unit and can be driven by the power unit to spin the lower piston body, thereby changing the intersectional area of the passage holes, and the flow velocity and total flow from one chamber to another chamber within the reservoir is changed, achieving the variable damping adjustment.
