A bi-directional damping system generates damping forces in two opposing directions. A shaft has a plurality of bi-directional damping modules fixedly coupled thereto. Each module includes a fluid-filled variable-volume first chamber including at least one port through which fluid can flow based on changes in volume of the first chamber, and a fluid-filled variable-volume second chamber including at least one port through which fluid can flow based on changes in volume of the second chamber. The first chamber and second chamber are fluidically isolated from one another. A fluid-filled spacer chamber is coupled to adjacent ones of the modules.

Example bicycle suspension components are described herein. An example damper for a bicycle suspension component includes a damper body and a damper member disposed in the damper body to control a flow of fluid between a first chamber and a second chamber in the damper body. The damper member includes a damper member body and a flow member movable relative to the damper member body along an axis of movement. The damper member body has a set of radial openings distributed circumferentially around the damper member body. The radial openings define flow paths that are transverse to the axis of movement. The flow member is movable between a first position in which the radial openings are unblocked and a second position in which the radial openings are blocked.

A suspension strut for a vehicle comprises: a first connector for connecting to a first point on the vehicle; a second connector for connecting to a second point on the vehicle; and a damper assembly adapted to provide a damping force as fluid flows through the damper assembly during relative compression between the first point and the second point, wherein the damper assembly comprises a side wall and a damper aperture in the side wall, wherein the damper aperture is open throughout operation of the strut to allow fluid to flow through the damper assembly.

The invention relates to a vibration damper for a motor vehicle comprising an inner tube, an outer tube and at least one compensating chamber, which is formed between the inner tube and the outer tube and comprises at least one gas bag, which is arranged in the compensating chamber, wherein the compensating chamber is fluidically connected to at least one working area of the inner tube filled with a hydraulic fluid, wherein at least one guide element is provided, which deflects a flow of the hydraulic fluid during a rebound stage or a compression stage in such a way that the gas bag is indirectly subjected to flow. Furthermore, the invention relates to a motor vehicle.

A steering damper can minimize a mounting space and can achieve favorable damping force characteristics. A rod member is mounted on a side of a first end of a piston and passes through a side of a first end of the damper case. A cylinder has a stepped configuration including a small-diameter cylinder and a large-diameter cylinder. Insertion of the piston in the cylinder causes an oil chamber filled with damper oil to be divided into a first oil chamber that has the small-diameter cylinder as an outer circumference, a second oil chamber that has the large-diameter cylinder as an outer circumference and that contacts the rod member, and a third oil chamber that has the large-diameter cylinder as an outer circumference and that does not contact the rod member. The piston has a stepped configuration including a small-diameter portion associated with the small-diameter cylinder and a large-diameter potion associated with the large-diameter cylinder.
