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.

A solar tracker system includes a torque tube, a solar panel assembly attached to the torque tube, a housing defining a chamber and a fluid passageway extending from the chamber, and an active lock connected to a seal configured to prevent a flow path of fluid while in a sealed state and allow the flow path of fluid in an unsealed state. The system further includes a controller in communication with the torque tube and the active lock. The controller is programmed to receive a command to place the solar panel assembly in a stowed position, instruct the torque tube to rotate the panel assembly to a stowed angle corresponding to the stowed position, monitor a current angle of the panel assembly, compare the current angle to the stowed angle, and instruct the seal to transition to the sealed state when the current angle is equal to the stowed angle.

A shock absorbing device includes a control unit and a transmission unit. The control unit includes a first shaft and a second shaft which freely and rotatably extends through the first shaft. The first end of first shaft and the first end of the second shaft protrude beyond the shock absorbing device. The transmission unit includes a first bevel gear and a second bevel gear. The second shaft freely and rotatably extends through the first bevel gear. When the first shaft is rotated to drives the first bevel gear, the first bevel gear drives the second bevel gear to adjust the recovery damping of the shock absorbing device. When the second shaft is rotated, the compression damping of the shock absorbing device is adjusted. The cooperation of the first and second bevel gears makes the operation of the shock absorbing device be smooth and stable.

A shock absorber includes a hard-side damping element for applying resistance to a flow of liquid from a compression side chamber to an extension side chamber, a solenoid valve capable of changing an opening area of a compression side bypass passage for communicating the compression side chamber and the extension side chamber by bypassing the hard-side damping element, and a soft-side damping element provided in the compression side bypass passage in series with the solenoid valve. The hard-side damping element has an orifice and a leaf valve provided in parallel with the orifice. The soft-side damping element has an orifice having an opening area larger than that of the orifice.

In a vehicle suspension, a preload is adjusted by selective engagement of cam surfaces of different heights with a cam receiving part by rotation of an adjuster part, the adjuster part includes a vertical wall part erected in an axial direction of a spring from a spring receiving part and an engaging part with which a tool to rotate the adjuster part is to be engaged, and the engaging part includes a first engaging part formed by a gap between the plurality of vertical wall parts disposed separately from each other in a circumferential direction of the adjuster part and a second engaging part formed by a hole penetrating the vertical wall part.

A stator provided at a position facing an opening of a housing member. The stator includes a conical protrusion portion and a side surface made from a magnetic body. The side surface extends from an outer periphery of the reduced diameter portion in a direction away from the opening of the housing member. Also included is a yoke with a fixation hole having an inner peripheral surface to which a part of the side surface portion of the stator is fixed. A non-contact portion, where the yoke and the side surface portion are out of contact with each other, is formed on the housing member side of the fixation hole. Also included is a non-magnetic connection member joined by being heated between the housing member and the yoke, and a movable element provided axially movably in the housing member and made from a magnetic body.
