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 damper having a cylinder (10) with a partition wall (13); a rotor (20) having a shaft portion (21) opposing the partition wall; a first recess (16) formed on a distal end surface of the partition wall; an elastic body (40) installed in the first recess and closely contacting the shaft portion to seal a gap between the partition wall and the shaft portion; and a second recess (27) formed in a part of an outer peripheral surface of the shaft portion not opposing the distal end surface of the partition wall during operation, and forming a space (50) into which the elastic body can be inserted without being compressed by facing an opening of the second recess to an opening of the first recess during assembly.

Slide assemblies for motor vehicles are provided. In one example, a slide assembly for a motor vehicle includes a first member and a second member that is slidingly coupled with the first member. A first leaf spring device is disposed between the first and second members for facilitating relative sliding movement between the first and second members. The first leaf spring device includes a raised contact portion that slidingly interfaces with one of the first and second members during the relative sliding movement.

An air spring assembly is disclosed. The air spring assembly includes a piston assembly including a piston, at least one compliant member, a seal configured to provide an air tight seal between the piston and a wall of an air chamber, and a fastener configured to couple the piston with a shaft.

An object of the present invention is to provide a vibration damping device including a bearing member capable of achieving simplification of configuration in the vibration damping device, reducing frictional force during operation, and having an excellent wear resistance. A vibration damping device of the present invention includes a bearing structure, in which a metal bush (bearing member) has a resin layer on a side defined as a friction sliding surface of a base member, the resin layer includes polytetrafluoroethylene (PTFE) and a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin, and the metal bush is lubricated by a magneto-rheological fluid composition.

A solenoid valve that can be adjusted axially, and hermetically, to a first end of a body of a shock absorber in order to be able to regulate the hydraulic load of the shock absorber as well as guide the movement of the rod in a longitudinal direction. The solenoid valve includes a movable part that can be moved between an open fluid flow position and another closed fluid flow position, a regulating chamber that generates a pressure to move said movable part towards the opening and an elastic element that generates a closing force. Likewise, the solenoid valve also includes electronic means to exert a force on the movable part, to move it in the direction of movement, preferably by means of a magnetic load. The invention also includes a shock absorber with hydraulic load regulation that comprises a solenoid valve, like the one mentioned, adjusted hermetically to a first end of the body of said shock absorber.

A tuned mass damper for damping an oscillating movement of a structure along a first direction is provided. The tuned mass damper comprises a mass arranged to perform a reciprocating movement along the first direction in response to the oscillating movement of the structure, wherein the mass comprises a braking mechanism configured to at least partially brake the movement of the mass along the first direction when the mass exceeds a predefined speed.

A vibration damper including a frame having at least a first cavity, a frame first end and a frame second end spaced from the frame first end; a shaft slidably coupled to and extending into the frame where the shaft extends through the first cavity; a first vibration isolator disposed within the first cavity where the shaft extends through the first vibration isolator so as to capture the first vibration isolator within the first cavity where the first vibration isolator interfaces with the frame second end; and a second vibration isolator disposed on the shaft, where the shaft extends through the second vibration isolator so as to capture the second vibration isolator on the shaft where the second vibration isolator interfaces with the frame second end opposite the first vibration isolator, where the first vibration isolator and the second vibration isolator act only in compression.

A vibration damper includes a housing and a piston rod construct and arranged to reciprocate along an axis and with respect to the housing. The housing defines first and second ports. A chamber is defined by the housing and the piston rod and is in fluid communication between the first and second ports. A translating isolator of the damper is located in the chamber and is in sealing contact with the piston rod and the housing. The isolator translates in a first direction toward the first port when the piston rod moves in the first direction and translates in an opposite second direction toward the second port when the piston rod moves in the second direction.

A damper apparatus for reducing or braking a movement of a second part that is movable relative to a first part includes a first damper component connected to the first part, a second damper component connected to the first second part, and a damping mechanism. The first damper component is movable relative to the second damper component and the relative movement is or can be decelerated due to the damping mechanism. A switching mechanism with a first switching contact and a second switching contact is arranged or integrated on the second damper component. At least one actuating region is configured on the first damper component such that, when the first damper component moves relative to the second damper component, an electrically conductive connection is established or disconnected between the first switching contact and the second switching contact using the at least one actuating region of the first damper component.
