Present disclosure A hydraulic stopping damper includes a cylinder in which a work fluid is stored, a piston rod coupled such that one side of the piston rod is to be inserted into an inner space of the cylinder, and a rod guide through which the piston rod passes and coupled to one side of the cylinder. The hydraulic stopping damper includes a rebound spring surrounding the piston rod and disposed in an inner space of the cylinder, and a shock mitigator between the rod guide and the rebound spring, the shock mitigator configured to generate a damping force by a hydraulic pressure of the work fluid when one side of the rebound spring compressed in response to a rebound stroke of the piston rod is inserted into the rod guide.

A damper providing varying damping force is provided. The damper may include a housing and a rotary member rotatably received the housing. The rotary member may rotate within the housing between defined end points of travel to define an angular range of travel of the rotary member. An outermost surface of the rotary member may be spaced inwardly from an inner surface of the housing defined between the end points of travel to define a gap between the outermost surface of the rotary member and the inner surface of the housing throughout the angular range of travel. The gap may vary in dimension depending on a rotational position of the rotary member to provide varying damping rates within the angular range of travel of the rotary member.

A shock absorber includes a bearing unit having a bearing and a bearing holding member, and a seal unit having a seal member and a seal holding member. The seal holding member includes a seal accommodating portion being configured to accommodate the seal member, and an insertion hole through which a piston rod is inserted. The seal member is pressed against an outer circumferential surface of the piston rod and the seal accommodating portion by working-fluid pressure in the extension-side chamber. And the bearing is provided such that a first end surface of the bearing facing the seal member matches an aperture plane of a through hole of the bearing holding member or such that the first end surface of the bearing projects out from the aperture plane of the through hole.

An apparatus for stabilizing movements of two parts of a body region and/or of a sports device which are movable relative to one another, comprising a receptacle, which can be fixed to a first part of the region and/or device. An active body arrangement with an active body is received movably in the receptacle and can interact with the filling medium. A force transmission body can be fixed to a second part of the same region and/or device for transmitting an external force to the active body. The active body comprises at least one through-opening through which a filling medium in the receptacle can flow. The active body arrangement has a sealing lip for sealing a gap between an inner side of the receptacle and a lateral region of an outer side of the active body arrangement, the sealing lip being arranged on an outer side of the active body.

An embodiment of the present disclosure relates to a shock absorber. A shock absorber which is divided into a compression chamber and a rebound chamber by a piston valve in a tube having an interior filled with a fluid includes a first elastic member disposed in the compression chamber, a second elastic member disposed in the compression chamber to be spaced apart from the first elastic member, and a mid-guide member disposed between the first elastic member and the second elastic member and movable along a longitudinal direction of the compression chamber.

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.

The present disclosure relates to a hydraulic damper comprising a main tube, a piston assembly, a base valve assembly, and at least one hydraulic compression stop assembly cooperating with a compression valve assembly, and comprising a pin disposed slidably within the piston rod and biased to project an activating tip towards the compression chamber. Said compression valve assembly comprises at least one deflectable or floating disc covering compression flow passages, and biased by a piston member slidable along said axis and normally abutting a retaining surface, and a pressure chamber having one surface defined by a surface of said piston member abutting said retaining surface, wherein said pin upon sliding inside the piston rod facilitates a flow of the working liquid from the compression chamber into said pressure chamber to increase biasing load on said at least one deflectable or floating disc.

A restriction for a vibration damper, comprising an annular element with variable diameter which is supported by a support and which occupies a restriction position depending on a flow velocity of a damping medium within the restriction proceeding from an open position through a radial closing movement in direction of a flow guiding surface. The annular element has at least two legs supported so as to be movable around a pivot bearing.

The endurance of a bump stopper cap is improved by preventing a clearance from being generated between a back face of a top board portion of the bump stopper cap and a nib surface of a cylinder main body. A non-interference region in which a rib is not formed is disposed on the top side of a circular-cylinder portion of the bump stopper cap, and an interference region where the rib is formed is disposed on the opening side from this non-interference region. Since the non-interference region can be deformed freely in association with the deformation of the interference region when the bump stopper cap is pressed fit at the nib of the cylinder main body, a seating surface which is the back face of the top board portion can be properly seated on the nib surface of the cylinder main body.
