A vehicle damper is described. The vehicle damper includes: a cylinder; a piston within the cylinder; a working fluid within the cylinder; a reservoir in fluid communication with the cylinder via the working fluid, the reservoir operable to receive the working fluid from the cylinder in a compression stroke; a valve in a flow path between the cylinder and the reservoir; and a remotely-operable valve having a position allowing the working fluid to significantly by-pass the valve.

A controllable vibration damper with damping force control may include a damper tube housing that is filled with damping medium. The controllable vibration damper may also include a damping valve element that is structurally and fluidically connected to the damper tube housing for damping force control. The damping valve element may be configured as a pilot-controlled pressure-limiting valve having a pilot valve. Further, a two-stage pre-throttle valve assembly placed in front of the pilot valve. The damping valve element may be arranged internally with respect to the damper tube housing in some cases. In other cases, the tamping valve element may be arranged externally with respect to the damper tube housing.

A shock absorber includes a hollow cylinder body extending in an up-down direction, a rod pipe located on an axis of the cylinder body, provided to be relatively movable in an axial direction of the cylinder body with respect to the cylinder body, and provided in a form of receiving a force in the axial direction, a rod-shaped support body extending inside the rod pipe with an upper end fixed, a stroke sensor including a coil and a conductor provided to be able to detect relative displacement of the rod pipe with respect to the support body, and a hollow intermediate member provided between the inner peripheral surface of the rod pipe and the support body to allow movement in the axial direction.

A suspension apparatus includes: a damping device; an operating section; and a determination section. The determination section uses a base damping force determined based on a change velocity and an extension occasion adjustment value, or the base damping force, the extension occasion adjustment value and a zero occasion adjustment value to determine a target value of an extension occasion damping force. The determination section uses the base damping force, a compression occasion adjustment value and the zero occasion adjustment value, or the base damping force and the compression occasion adjustment value to determine a target value of an compression occasion damping force. The determination section uses the base damping force and the zero occasion adjustment value to determine a target value of a zero occasion damping force.

A continuously variable damper is disclosed. The damper includes an elongate outer tube and inner tube with a piston in the inner tube. The piston defines a rebound working chamber and compression working chamber. An active rebound valve is in fluid communication with the rebound working chamber through a rebound down tube, and an active compression valve is in fluid communication with the compression working chamber through a compression down tube. An intake compression valve is in fluid communication with the rebound working chamber through the rebound down tube, and an intake rebound valve is in fluid communication with the compression working chamber through the compression down tube. The opposite position of the intake valves balance the active rebound and compression valves to avoid asymmetric/bending loads on the inner tube in the damper.

A damper assembly includes a cylinder defining a chamber. The damper assembly includes a body supported by the cylinder and having a first surface and a second surface opposite the first surface. The body defines a passage extending from the first surface to the second surface. One of the first surface or the second surface define a slope at the passage. The damper assembly includes a check disc at the slope, the check disc selectively restricting fluid flow through the passage.
