A damper assembly comprises a main tube defining a fluid chamber. The main tube includes a first section, a second section, and an intermediate portion. A sleeve is disposed about the main tube. An external tube is disposed about the main tube and the sleeve. The external tube defines a compensation chamber between the sleeve and the external tube. A main piston divides the fluid chamber into a rebound chamber and a compression chamber. A piston rod couples to the main piston for moving the main piston between a compression stroke and a rebound stroke. The sleeve is in an abutment relationship with the second section of the main tube, radially spaced apart from the first section of the main tube, defining a compartment extending between the sleeve and the first section of the main tube. A housing for the damper assembly is also disclosed herein.

A damper with inner and outer tubes and a piston slidably disposed within the inner tube to define first and second working chambers. A fluid transport chamber is positioned between the inner and outer tubes. A collector chamber is positioned outside the outer tube. An intake valve assembly, abutting one end of the inner tube, includes first and second intake valve bodies and a divider body, which define first and second intermediate chambers in the intake valve assembly. An accumulation chamber is positioned between the intake valve assembly and a closed end of the outer tube. The first intermediate chamber and accumulation chamber are arranged in fluid communication with the collector chamber. A first intake valve controls fluid flow between the second working chamber and the collector chamber. A second intake valve controls fluid flow between the second intermediate chamber and the collector chamber.

A damper with inner and outer tubes and a piston disposed within the inner tube to define first and second working chambers. A fluid transport chamber is positioned between the inner and outer tubes. A collector chamber is positioned outside the outer tube. An intake valve assembly, abutting one end of the inner tube, is positioned inside the outer tube to define a first intermediate chamber that is arranged in fluid communication with the collector chamber. The intake valve assembly includes a central passage that is arranged in fluid communication with the second working chamber and one or more intake valves that control fluid flow through the intake valve assembly between the first intermediate chamber and the central passage and between the first intermediate chamber and the fluid transport chamber.

A vibration damper with adjustable damping force, having an inner cylinder, which has a working chamber and a flow connection to a damping valve device situated outside forming an outer cylinder. The flow connection is made in a component separate from the inner cylinder, and the separate component is formed by an adapter sleeve, which forms a part of the working chamber and has a connection piece to the damping valve device.

This hydraulic damping device comprises a cylinder for containing oil; a reservoir chamber R which is provided in the outer part of the cylinder and in which liquid accumulates; a piston provided so as to be axially movable within the cylinder and dividing the space within the cylinder into a first oil chamber and a second oil chamber, which contain oil; a baffle member provided as a separate element from the cylinder, the baffle member having a body which is provided in the reservoir chamber R, and also having a protrusion which protrudes from the body, the baffle member preventing the waving of the surface of oil in the reservoir chamber R; and a limiting section (first section to be held) provided to the baffle member and limiting the movement of the baffle member on both one side and the other side in the axial direction.

A damper for a telescopic fork leg for a front fork of a vehicle, wherein the damper comprises a twin-tube cylinder and a piston rod assembly comprising a piston rod, wherein a first piston is attached to the inner end portion of the piston rod, wherein a second piston is attached to the piston rod between the first piston and an outer end portion of the piston rod, wherein the inner tube is provided with at least one outlet hole 19 through the wall of the inner tube, the outlet hole being positioned such that a sealing portion of the second piston at compression of the damper travels past at the at least one outlet hole, and wherein the inner tube is provided with at least one return hole through the wall of the inner tube, the at least one return hole being positioned such that it connects a chamber of the twin-tube cylinder to an outer volume of the cylinder.

A damper including a damper tube, a piston assembly, a piston rod attached to the piston assembly, and a monolithic base. The piston assembly is slidingly disposed within the damper tube. The monolithic base includes a closed end, an open end, a base portion at the closed end, and a wall portion. The base portion is joined to and seals one end of the damper tube. The base portion includes a concave depression that tapers inwardly from a base portion perimeter to a cup bottom. The wall portion extends longitudinally from the base portion perimeter to the open end such that the cup bottom is positioned between opposing sides of the wall portion. Integrally formed fastening eyes are provided in the opposing sides of the wall portion.

A steering damper assembly includes a cylindrical pressure tube defining a working chamber; a piston assembly disposed in the working chamber; a reserve tube extending circumferentially around the pressure tube and defining a reservoir chamber that is radially between the reserve tube and the pressure tube; a base valve fluidly connecting the working chamber and the reservoir chamber; and a piston rod fixed to the piston assembly. The reserve tube includes a cylindrical portion and a bulged portion. The cylindrical portion extends concentrically around the pressure tube. The bulged portion includes a first circumferential section and a second circumferential section, the first circumferential section having a maximum radial distance at most equal to an inner radius of the cylindrical portion, and the second circumferential section having a maximum radial distance greater than the inner radius of the cylindrical portion.

An extension assembly for a damper includes an extension post having an upper end and a lower end opposite to the upper end. The extension post includes a coupling portion, a narrow portion defining a deformed section, and a wide portion disposed between the coupling portion and the narrow portion. A diameter of the wide portion is greater than a diameter of the narrow portion. The extension assembly includes a retaining member having a sleeve portion received on the narrow portion of the extension post and a plurality of support portions extending from the sleeve portion. Further, the deformed section of the narrow portion secures the retaining member to the narrow portion. The extension assembly further includes a sealing ring disposed around the retaining member. The sealing ring is disposed between the wide portion of the extension post and the plurality of support portions of the retaining member.

Provided is a shock absorber that includes a middle chamber formed by a piston, a first damping-force generating device that is provided between an upper chamber and the middle chamber and generates a damping force, a second damping-force generating device that is provided between a lower chamber and the middle chamber and generates a damping force, and a position-based state changing device that changes a state of a passage to a state in which the upper chamber and the lower chamber communicate with each other, a state in which the upper chamber and the middle chamber communicate with each other, or a state in which the lower chamber and the middle chamber communicate with each other depending on a position of the piston.
