An adjustment wheel arrangement for a shock absorber with a first adjustment wheel which is configured to connect in a torque-proof fashion to an adjustment tube of a piston rod of the shock absorber, and a second adjustment wheel which is configured to connect in a torque-proof fashion to an adjustment rod extending through the adjustment tube. The first adjustment wheel and the second adjustment wheel can be twisted relative to each other by means of a push-twist connection but are or can be connected by form-fit to each other in the axial direction. The push-twist connection is configured in the manner of a key-lock, such that the first adjustment wheel and the second adjustment wheel can be connected to or separated from each other only in a single relative orientation.

A shock absorber has a valve controlling the flow rate of fluid between a first chamber and a second chamber. The shock absorber may include a blocker that has a variable profile. The blocker may be rotatable using an external adjuster to position the blocker to variably occlude an aperture and vary the damping of the suspension. A bias may also be positioned adjacent the blocker to allow force from the fluid to move the blocker and expose the aperture, thereby allowing fluid to flow through the entirety of the aperture.

Present invention concerns a laminated spring containing valve on a cylinder that contains two compartments which are separated by a piston, which ensures the adjustment of the fluid flow rate between the two compartments by being sensitive to the pressure difference between the two compartment. Present invention explains a valve and its control method which provides a dynamical control over the fluid flow between the two compartments and the flow rate. Besides, this invention explains a valve set and a prosthetic joint, which contains this set, that ensures the adaptive movement of the prosthetic limbs of the amputees with the natural movement phases.

An adjustable valve for a shock absorber comprises a hollow valve body comprising a plurality of valve apertures. A rotatable sleeve is rotatably arranged around at least part of the hollow valve body. The rotatable sleeve comprises a plurality of sleeve apertures. The adjustable valve further comprises a movable spool slidably arranged within the hollow valve body and configured to move relative to the hollow valve body. The movable spool divides the hollow valve body into a first chamber and second chamber. Rotation of the rotatable sleeve relative to the hollow valve body varies an alignment between at least one sleeve aperture of the plurality of sleeve apertures and at least one valve aperture of the plurality of valve apertures. Movement of the movable spool relative to the hollow valve body varies an available opening area of at least one valve aperture of the plurality of valve apertures.

The invention describes a damper control arrangement (24) for a damper (2) in an electronic suspension assembly (4) of a two-wheeled vehicle (3), the damper control arrangement (24) comprising a sensor arrangement comprising a number of sensors (240AS, 240P, 240M) arranged to measure motion-related parameters of the two-wheeled vehicle (3); an upward lift detection means configured to detect an upward lifting action (Z.sub.lift) on the sprung mass from the sensor outputs (240x, 240y, 240z, 240p, 240m); and a decision module configured to generate a control signal (24out) to open the damper (2) in response to the detected upward lifting action (Z.sub.lift). The invention further describes an electronic suspension assembly (4) and a method of controlling an electronic suspension assembly (4).

A damper valve for a vibration damper, in particular of a vehicle, comprises a valve body, at least one control disc arranged on the valve body, and at least one rotatably mounted adjustment element, wherein the valve body, the control disc and the adjustment element are arranged coaxially, and wherein the control disc is connected to the adjustment element for conjoint rotation and the control disc is rotatable relative to the valve body in order to open up or block at least one of a plurality of through-channels in the valve body for the flow of a damper fluid, wherein the control disc has at least two through-openings with different cross sections, in order to change the flow of the damper fluid, in particular the flow cross section, through the through-channels in the valve body.

A check shim style electronic modal base valve is disclosed. The check shim style electronic modal base valve includes a motive component, a controller communicatively coupled with the motive component, and a control valve having a lead screw is coupled with the motive component. The controller is configured to control an operation of the motive component, wherein a movement of the motive component is configured to cause the control valve to adjust a flow rate for a flow path through the check shim style electronic modal base valve.
