The annular main body (201) defines an annular disc-shaped portion (202) having an upper surface (203), a lower surface (204), an outer peripheral edge (205) and an inner edge (206). Said inner edge (206) bounds a circular opening (207) extending the full height of said annular disc shaped portion (202) between said upper and lower surfaces (203, 204). The annular main body (201) further defines an annular collar portion (208) upstanding from the upper surface (203) of said disc shaped portion (202) adjacent said peripheral edge (205) of said disc shaped portion (202), said annular collar portion (208) extending height-wise from a base end (209) joined to said disc-shaped portion (202) to an upper end (210), and width-wise from an inner edge (211) to an outer peripheral edge (212), said inner edge (211) of said annular collar portion (208) bounding a circular opening (213) extending the full height of said annular collar portion (208). The annular main body (201) also further defines an annular flange portion (216) extending height-wise downwardly from the lower surface (204) of said disc-shaped portion (202) from a base end (217) joined to said lower surface (204) of said disc-shaped portion (202) to a distal end (218), and width wise from an inner edge (219) to an outer edge (220).

A damper comprises a pressure tube extending longitudinally between a first pressure tube end and a second pressure tube end, a piston arranged in sliding engagement inside the pressure tube, a piston rod coupled to the piston, a hydraulic rebound stop positioned in a first working chamber and including a sealing ring circumferentially extending around the piston rod and within the pressure tube. The sealing ring at least partially defining a high-pressure region within the pressure tube during a rebound stroke the damper further comprising a pressure relief valve in fluid communication with the high-pressure region. The pressure relief valve being operable to allow pressurized fluid from the high-pressure region to pass therethrough once a predefined pressure threshold has been reached.

A baffle press-fit against an inner portion of an outer tube defining an interior of a hydraulic damper. The baffle comprising a first wall, a second wall, opposite the first wall, a circumferential third wall, and a channel formed between at least a portion of the circumferential third wall and the inner portion of the outer tube. The channel comprising an inlet formed along at least a portion of the first wall, an outlet formed along at least a portion of the second wall, and a groove formed along at least a portion of the circumferential third wall and fluidly coupling the inlet to the outlet.

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.

A gas spring comprising: a cup-shaped body; a movable piston which is inserted in an axially slidable manner in the cup-shaped body and is coupled to the cup-shaped body in a fluid-tight manner, so as to delimit a variable-volume closed chamber adapted to contain a pressurised gas; and a safety plug provided with a shank which extends in pass-through manner in the bottom wall of the cup-shaped body, and protrudes cantilevered within the cup-shaped body so that its distal end can be reached/struck by the movable piston in the case of overtravel; the distal end of the shank having a substantially tubular structure that directly communicates with the closed chamber.

A solar tracker system includes a torque tube, a solar panel assembly attached to the torque tube, a housing defining a chamber and a fluid passageway extending from the chamber, and an active lock connected to a seal configured to prevent a flow path of fluid while in a sealed state and allow the flow path of fluid in an unsealed state. The system further includes a controller in communication with the torque tube and the active lock. The controller is programmed to receive a command to place the solar panel assembly in a stowed position, instruct the torque tube to rotate the panel assembly to a stowed angle corresponding to the stowed position, monitor a current angle of the panel assembly, compare the current angle to the stowed angle, and instruct the seal to transition to the sealed state when the current angle is equal to the stowed angle.

A suspension unit has a piston assembly connected to an adjuster. The piston assembly has three or more concentric cylindrical bodies including: an outer tube; an inner tube, and a dampener rod. The dampener rod is inside and concentric to the inner tube. The outer tube is rigidly connected to the dampener rod. The inner tube is telescopically mounted to the outer tube. The inner tube is inside and concentric to the outer tube. The adjuster has an adjuster compression entry port. The axle clamp rebound port connects to an adjuster block rebound entry port. The adjuster block has a high-speed compression cavity formed on an end of the adjuster block.

A ring circumscribing a moveable rod of a hydraulic damper, the moveable rod defining a central axis, the ring comprising a first circumferential surface, a second circumferential surface, a first finger, a second finger, a first flange, and a second flange. The first finger and the first flange defining a first end of the ring. The second finger and the second flange defining a second end of the ring.

A vibration damper having a hydraulic compression stop includes: a cylinder filled with a damping medium; a piston rod guided in the cylinder the cylinder having a first piston fastened to the piston rod and slidable on an inner wall of the cylinder; and a second piston arranged on the piston rod at an axial distance from the first piston the second piston being slidable in a pressure cylinder. The pressure cylinder is formed with respect to the cylinder by a separate plastic pressure sleeve having a bottom, and the bottom of the pressure sleeve and a coating surface of the base on a side of the base facing away from the pressure sleeve are connected to each other via at least one web.

The disclosure relates to a vibration damper comprising two adjustable damping valve devices, wherein a damping valve device is connected to a piston-rod-side working chamber via a fluid connection and a damping valve device is connected to a working chamber spaced apart from a piston rod within a cylinder filled with damping medium. A fluid connection between the damping valve device and the working chamber occurs via at least one tube element. Both adjustable damping valve devices are connected to a common balancing chamber for receiving the damping medium displaced out of the working chambers by the piston rod. A line block is connected to the cylinder, which forms a first fluid connection to the damping valve device for one of the working chambers and forms an intermediate tube, encasing the cylinder, for a second fluid connection to the damping valve device for the other of the two working chambers. The second fluid connection is also connected to the line block. Both fluid connections have a separate radial channel within the line block, each being connected to an inlet opening of the damping valve devices. A reducer part is arranged between the cylinder and the first fluid line of the line block, and the second fluid line runs within the line block within a projection surface of the cylinder.
