摘要： A valve mechanism includes: a cylindrical body; a plurality of valve bodies; and a drive valve. The drive valve includes a shaft portion having therein a flow path penetrating in the axial direction, and a step portion extending from an outer peripheral surface of the shaft portion to a radial outside of the shaft portion. The shaft portion has a tip portion which extends further on the cylindrical body side than the step portion. An outer diameter of the tip portion is smaller than an outer diameter of the step portion. A gap between the valve bodies is changed by elastically deforming an inner peripheral portion of the valve body, which comes into contact with the drive valve moved in a direction approaching the valve body, in a direction approaching the cylindrical body with respect to an outer peripheral portion of the valve body.

摘要： A shock absorber for a wheel suspension of a vehicle may include an outer cylinder, an outer piston that is axially displaceably guided in the outer cylinder, an inner piston that is axially displaceably guided in the outer piston, and a piston rod that is connected to the inner piston and that is guided out of the outer piston. A surface, which is located remote from the piston rod, of a piston portion of the outer piston, which is axially displaceably guided on an inner lateral surface of the outer cylinder, is connected so as to communicate partially with surroundings of the shock absorber.

摘要： Disclosed is a hydraulic damper wherein the main damper tube has a narrowed section and it includes at least one additional piston assembly adapted to be received in the narrowed section to generate additional damping force. The piston assembly comprises a compression valve assembly and a rebound valve assembly each comprising at least one deflective disc. A sealing ring assembly is disposed between the compression and rebound valve assembles and comprises a first annular member having a plurality of channels covered by the deflective disc of the compression valve assembly; a second annular member having a plurality of channels, covered by the deflective disc of the rebound valve assembly; an axial projection between the annular members radially internal to the axial channels; and a sealing ring displaceable axially between the annular members and radially over the axial projection and adapted to cooperate with the narrowed section of the tube.

摘要： Embodiments of three parameter isolators including rolling seal damper assemblies are provided. In one embodiment, the three parameter isolator includes first and second isolator end portions, which are opposed along a working axis. A main spring and a tuning spring are mechanically coupled in parallel between the first and second isolator end portions. A rolling seal damper assembly is further mechanically coupled between the first and second isolator end portions in parallel with the main spring and in series with the tuning spring. The rolling seal damper assembly includes a first hydraulic chamber, a second hydraulic chamber fluidly coupled to the first hydraulic chamber, and first and second rolling diaphragm seals partially bounding the first and second hydraulic chambers, respectively. In certain implementations, the rolling seal damper assembly also contains a thermal compensator piston to which the first rolling diaphragm seal is attached.

摘要： A twin-tube hydraulic damper assembly includes a main tube having an internal radius extending along a center axis between a first end and a second end. An external tube is disposed on the center axis extending about the main tube. A base valve attached to the second end for controlling the flow of the working liquid during the compression stroke and the rebound stroke. A rebound valve of at least one rebound deflective disc having a thickness is disposed in the compression chamber and adjacent to the body. The rebound deflective disc has an external circumferential surface spaced from the main tube defining an annular damping gap extending about the center axis and having a radial width whereby a ratio of said radial width of the annular damping gap to the internal radius is less than 10%.

摘要： A shock absorber according to one embodiment includes a damper case provided to hold an outer tube and an inner tube such that an upper end of the outer tube is positioned closer to a side on which a piston rod is disposed than an upper end of the inner tube. The damper case includes a damper housing portion that houses a damper unit, a compression-side communication path through which an inner side of the inner tube and the damper housing portion communicate with each other, an extension-side communication path through which an annular passage and the damper housing portion communicate with each other, and a passage opening which is formed on the opposite side to the piston rod of the outer tube. The extension-side communication path and the annular passage communicate with each other through the passage opening.
