A damper valve with an adjustable effective stiffness of a shim. The damper valve includes a piston. The piston has a fluid path formed therethrough. A shim is disposed proximate the fluid path formed through the piston. A stiffness adjustment feature is coupled to the shim, and the shim is disposed between the piston and the stiffness adjustment feature. The stiffness adjustment feature is configured to adjust the effective stiffness of the shim without affecting a preload applied to the shim.

An electronic modal base valve is disclosed. The electronic modal base valve includes a motive component, a controller communicatively coupled with the motive component, and a control valve 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 electronic modal base valve.

A vehicle suspension damper including: a cylinder; a piston assembly; and an adjuster, wherein the piston assembly compresses fluid as it moves within the cylinder and the adjuster obstructs fluid flow from a first side of a damping piston of the piston assembly to a second side of the damping piston.

A gas spring curve control valve for a adjustable-volume gas-pressurized device is described. The valve allows for selection from among at least four spring curves and can be packaged in small spaces/devices. In an exemplary embodiment of the invention, a rotary cam having grooves and lobes that interact with spring loaded ball bearings and an external adjuster knob are used to easily change the gas spring curve “on-the-fly” and with minimal user effort.

A main orifice plate assembly may be configured to transition a multi-actor damping system from a first damping actor configuration to a second damping actor configuration. The multi-actor damping system may be used in a shock strut assembly to alter a damping curve of the shuck strut assembly. The main orifice plate assembly may be a part of a main orifice assembly including an orbital cam. The main orifice plate may include a flow restrictor. The flow restrictor may be configured to retract or deploy in response to main orifice plate rotating about the orbital cam. The first damping actor configuration may correspond to a first damping curve. The second damping actor configuration may correspond to a second damping curve. The first damping curve being different than the second damping curve.

A damper apparatus includes an adjusting bolt including a head part rotatably stored in an adjusting bolt storage part formed in a base part, and a male thread part including a tip end formed in a male thread shape. An adjusting member includes: a female thread part, which is a part in a female thread shape fastened to the male thread part of the adjusting bolt and movably provided along an axis line of the adjusting bolt; a tapered surface part with which the tip end of a push rod comes into contact and formed in a tapered shape with respect to the axis line of the adjusting bolt; and wall parts rising from both ends of the tapered surface part with reference to the circumferential direction of the adjusting bolt, and interposing the push rod therebetween.

A shock absorber has a damping force generator including a spool valve body that is reciprocally engaged with a cylindrical portion of a piston and pressed from both sides by a pair of compression coil springs. The cylindrical portion has first openings for extension and compression strokes, and the spool valve body has second openings for extension and compression strokes. When the piston is displaced relative to the cylinder, the spool valve body is displaced by a difference between pressures in upper and lower cylinder chambers, so that the damping force generator changes a degree of overlap of the first and second openings for the extension stroke in the extension stroke and a degree of overlap of the first and second openings for the compression stroke in the compression stroke.

A vehicle suspension damper including: a cylinder; a piston assembly; and an adjuster, wherein the piston assembly compresses fluid as it moves within the cylinder and the adjuster obstructs fluid flow from a first side of a damping piston of the piston assembly to a second side of the damping piston.

A shock absorber device for a motor vehicle includes a spring support, a spring, a damping device configured to exert a damping force, a control unit, an electric motor electrically connected to the control unit and controllable by the control unit through a power supply signal emitted by the control unit, such that the electric motor provides a torque or a force corresponding to the power supply signal, and conversion means configured to control the damping device turning the torque or force outputted into a further force corresponding to the torque or force outputted and exerted by means of the damping device, wherein the control unit is configured to receive a first control signal indicative of a target value for the further force and to provide the power supply signal as a function of the first control signal, such that the power supply signal corresponds to the target value for the further force, the control unit being coupled to the spring support in a fixed position relative to the spring support.
