The present invention relates to a shock absorber with mechanical stop for torque converter that has a simplified manufacturing process and also prevents the exterior springs from reaching the solid length. To achieve the foregoing, a shock absorber with mechanical buffer stop is implemented which comprises a drive plate; at least one exterior spring; and a driven plate, wherein the driven plate additionally comprises at least one mechanical stop which is configured to make contact with the drive plate when the drive plate compresses each exterior spring, and each mechanical stop is located such that it prevents each exterior spring from reaching a solid-length condition.

The invention relates to an oscillation damper which is in particular suitable for wind turbines and which is based on the eddy current principle and is temperature-controlled in such a way that it can not only effectively dissipate the heat generated by the eddy current but can also effectively and self-adjustingly compensate for the damping loss occurring at higher temperatures.

A rotary magnetic damper comprises a first, rotary damper element, a second, static damper element and a rotary input coupled to the rotary damper element. The coupling between the input and the rotary damper element is such that rotation of the rotary input causes the rotary damper element to progressively magnetically engage the static damper element whereby to progressively increase a damping force created by the damper. The rotary damper element may be a magnet or magnets mounted on a carrier which threadingly engages a screw driving element such that as the input rotates the carrier, it and the rotary damper element translate axially along the screw driving element towards the static damper element.

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.

A restraint system includes a housing, a spool rotatably coupled to the housing, a pinion fixed to the spool, a rack engaged with the pinion, and a piston attached to the rack and the housing. The piston is filled with a resilient material. The resilient material may be a heterogeneous mixture of a liquid and hydrophobic, nanoporous particles.

The invention relates to a stabilizer assembly of a two-track vehicle for stabilizing a rolling movement, the stabilizer assembly being operable on at least two different spring characteristics, comprising a first and a second stabilizer half, each coupled to a wheel of the vehicle, wherein the first and the second stabilizer halves are coupled such that they can rotate relative to each other about their longitudinal axis by means of a spring element, whereby the stabilizer is operable with a first spring characteristic, and wherein the first and the second stabilizer halves can be hydraulically coupled such that they can rotate relative to each other about their longitudinal axis by means of a hydraulic actuator, whereby the stabilizer is operable using at least one second spring characteristic. The actuator comprises at least two work chambers which are filled with a hydraulic medium and coupled to each other by a fluid-conducting connection, and the actuator comprises a transmission unit which is designed such that a rotational movement of the stabilizer halves can be converted into a translational movement of an intermediate element arranged between the two work chambers, and a volume flow of the hydraulic medium from the one work chamber into the other work chamber can thus be produced.

A cushioning mechanism of a heat sealing device applied in a film wrapping machine has a leading cylinder, an elastic unit, a first cushioning plate, a second cushioning plate, and a cushioning component. The elastic unit, the first cushioning plate, and the second cushioning plate are sequentially disposed on the leading cylinder along an axial direction of the leading cylinder; the first cushioning plate and the leading cylinder rotate synchronously. The cushioning component has a cushioning groove and a cushioning protrusion respectively formed on the first cushioning plate and the second cushioning plate. When the second cushioning plate is rotated, the cushioning protrusion presses one of two groove walls of the cushioning groove such that the first cushioning plate can rotate synchronously with the second cushioning plate for transmission or move relative to the leading cylinder to compress the elastic unit for cushioning.
