摘要： 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.

摘要： A hydraulic suspension damper includes a tube having an opened end and a closed end defining a compartment. A main piston is disposed in the compartment dividing the compartment into a compression chamber and a rebound chamber. A piston rod is attached to the main piston. A rod guide is disposed at said opened end. A stroke stop arrangement includes an insert and an additional piston attached to the piston rod. The insert has a narrowed section including an inner surface defining at least one recess between the distal end and the rod guide and extends axially along the insert in fluid communication with the compression chamber for allowing working liquid flow from the rebound chamber to the compression chamber during the rebound stroke. The at least one recess includes three recesses disposed equidistantly and spaced from one another.

摘要： To achieve the object described above, a shock absorber to solve the problem of the present invention includes a cover that covers an outer periphery of a cylinder which a reaction force air chamber forming member is slid ably in contact with, so that a slidable movement surface of the cylinder on which the reaction force air chamber forming member slidably moves is protected by the cover. Therefore, the slidable movement surface of the cylinder is not damaged by being hit by a flying stone or the like, an air tight property of the reaction force air chamber is maintained, and characteristics of an air spring included in the shock absorber do not change.

摘要： A damper includes a cylinder, an annular rod guide, an annular seat, a rod, an annular oil seal, a rebound cushion, and a communication passage. The cylinder houses an action chamber. The rod guide is secured to one side opening of the cylinder. The seat is secured to the rod guide. The rod is inserted through inner peripheral sides of the rod guide and the seat. The oil seal is held to an inner periphery of the rod guide and slidably in contact with an outer peripheral surface of the rod. The rebound cushion bumps against the seat. The communication passage transmits a pressure in the action chamber to the oil seal. An opening on the communication passage on the action chamber side is disposed on an outer peripheral side relative to a part of the seat against which the rebound cushion bumps.

摘要： A position-and-velocity dependent hydraulic damper is provided. The hydraulic damper has piston valve fixed to a tip of a piston rod, a base valve, and a reservoir chamber. The base valve has a compression side port. Between a first valve and the base valve, a first spiral spring is provided, and between the first valve and the piston valve, a second spiral spring is provided. The compression side port is closed by the first valve around the maximum compression state, reducing the flow rate of oil to the reservoir chamber. A second valve passing through the centers of the first valve and the base valve adjusts the flow rate of the oil to the reservoir chamber with a pressure equal to or higher than a prescribed level of an oil chamber.

摘要： A damper rod bushing operatively connects an end member of a gas spring and a damper rod of a damper to at least partially form a gas spring and damper assembly. The damper rod bushing is constructed for exposure to gas pressure within a spring chamber of a gas spring and damper assembly such that pre-load forces due to gas pressure within said spring chamber act on said damper rod bushing. The damper rod bushing can include an outer support element, an inner support element and an elastomeric connector element operatively connected between the outer and inner support elements such that a substantially fluid-tight seal is formed therebetween. A gas spring and damper assembly including such a damper rod bushing, as well as a suspension system including one or more of such gas spring and damper assemblies and a method of assembly are also included.
