Providing a vibration damping shelf which can suppress fall of articles placed on a shelf member while suppressing shake of other articles or the like. The vibration damping shelf includes a damper and shelf plates. The damper has two ends mounted, on a top surface of a piece of furniture and a ceiling spaced from each other in an up-down direction. The shelf plates are held on the damper.

A drive for adjusting an adjustment element of a motor vehicle, the drive including a hollow cylinder, a rod guided axially therein, two articulated parts configured to provide linear drive movements to the motor vehicle and form a drive connection to the adjustment element and the rest of the motor vehicle. The one articulated part axially fixed to a first component of the components of the drive unit and the other articulated part axially fixed to a second component of the components of the drive unit in the installed state. The drive has a drive spring assembly including a drive spring acting on the articulated parts. In the installed state, at least one of the components of the drive unit is axially fixed to a securing element by a threaded connection, and the securing element projects radially into an axial projection of a spring material of the drive spring assembly.

A shock absorber includes a cylinder-side member having an inner cylinder, a piston-side member having a piston and a piston rod that move relative to the inner cylinder, and a phase correction communication passage. The phase correction communication passage is provided between a bottom-side oil chamber, which is one side chamber, and a rod-side oil chamber, which is the other side chamber. That is, the phase correction communication passage is provided in the inner cylinder which is the cylinder-side member and communicates the bottom-side oil chamber and rod-side chamber with each other. By having a spiral conduit that advances in the axial direction while spiraling (orbiting) multiple times at the same diameter, the phase correction communication passage is configured as a second damping mechanism which generates a force (an axial force) that advances the phase of the damping force.

A hydraulic damper including a tube. A piston assembly is disposed slidably inside the tube and divides the tube into a rebound chamber and a compression chamber. A fluid compensation chamber is located outside of the tube. A base valve assembly controls the flow of the fluid between the compression and compensation chambers. A hydro-mechanical compression stop assembly includes a covering member that overlies the base valve assembly and defines a main flow channel and an auxiliary flow channel that each fluidly connect the compression chamber and the base valve assembly. A closing member selectively closes the main flow channel. A first telescoping sleeve is coupled with the piston assembly and a second telescoping sleeve has a base connected to the closing member. A first spring is compressed between the piston assembly and the base to bias the closing member in an extended position.

Solar tracker systems include a torque tube, a solar panel attached to the torque tube, and a damper assembly. The damper assembly includes an outer shell, a first chamber wall and a second chamber wall within the outer shell at least partially defining a chamber, and a piston to direct fluid through the chamber. A valve is within the chamber that includes a first axial end, a second axial end, and a seal positioned on the first axial end. The damper assembly further includes a biasing assembly that biases the valve into a first position within the chamber in which the seal is spaced from the first chamber wall. The valve is moveable within the chamber from the first position to a second position in which the seal contacts and seals against the first chamber wall to prevent the flow of fluid through the chamber.

A pressure-balanced shock absorber has an outer tube, an inflatable base, a piston tube, a valve adjusting rod, a piston base, an inner tube, and an adjusting resilient element. The inflatable base has a valve passage and a first valve core. The first valve core selectively seals the valve passage. The piston tube communicates with the valve passage. The valve adjusting rod is movably mounted in the valve passage of the inflatable base and the valve tube. The piston base is connected to the piston tube and has a piston passage. A second valve core selectively seals the piston passage. The inner tube is mounted around the piston tube. The piston base divides the inner tube into a first air chamber and a second air chamber. The adjusting resilient element is disposed in the piston tube to achieve the effect of inflating two air chambers.

A shock absorber includes a plate and a lock portion. The plate is secured to a distal end side with respect to a nut of a piston rod by crimping the piston rod. The lock portion is disposed on a bottom portion side of a cylinder and locks the plate. The shock absorber is maintained in a contraction state by the plate being locked by the lock portion.

A shock absorber includes a tube that has one end from which a piston rod extends, a capping member disposed in an end portion at a side of the one end in the tube, the capping member including a locking portion formed on an outer peripheral surface, and a cover member disposed in a distal end side of the piston rod, the cover member including a locked portion locked to the locking portion formed on an inner peripheral surface, wherein the shock absorber is kept in a contracted state by the locked portion of the cover member being locked to the locking portion of the capping member.

A valve body for a damper includes a plurality of pressure tubes of the damper having different diameters. The valve body includes a plurality of fluid passages. The valve body further includes a plurality of stepped regions having different diameters relative to a valve axis of the valve body. Each stepped region is configured to be selectively coupled to one of the plurality of pressure tubes having a corresponding diameter.

A seal guide unit for guiding and sealing a piston rod of a vibration damper having a first guide element and a second guide element fixedly connected to the first guide element and arranged coaxial to the first guide element, and a radially moveable piston rod seal arrangement arranged coaxially between the two guide elements and is at least indirectly surrounded in circumferential direction by at least one guide element, including a defined radial annular gap, and comes in at least indirect axial contact with at least one guide element. The piston rod seal arrangement includes a piston rod seal and a sliding element which encloses the piston rod seal in circumferential direction and axially limits the piston rod seal at least on one side. The sliding element has a lower friction coefficient than parts of the seal guide unit adjoin the piston rod seal arrangement.
