摘要： A shock absorber for a wheel suspension of a vehicle may include an outer cylinder, an outer piston that is axially displaceably guided in the outer cylinder, an inner piston that is axially displaceably guided in the outer piston, and a piston rod that is connected to the inner piston and that is guided out of the outer piston. A surface, which is located remote from the piston rod, of a piston portion of the outer piston, which is axially displaceably guided on an inner lateral surface of the outer cylinder, is connected so as to communicate partially with surroundings of the shock absorber.

摘要： Methods of moving an aircraft undercarriage that is movable between a retracted position and a deployed position generally include: using a rotary electromechanical type drive actuator coupled to a portion of the aircraft undercarriage to raise it from the deployed position to the retracted position; disengaging the drive actuator during a descent of the undercarriage from the retracted position to the deployed position and using a hydraulic linear shock absorber coupled to a portion of the undercarriage to regulate the rate of descent and to absorb shock on arrival of the undercarriage in the deployed position; and neutralizing the shock absorber while raising the undercarriage.

摘要： A rigid substructure (12) tied to a restrained column (16) at different floors undergoes rigid body rotation due to lateral dynamic loading. Flexural members (18) that are connected to the substructure (12) and another anchor column (14) resist the rigid body rotation and undergo vertical deflections. Damped diagonals (20) connected to common nodes of the rigid substructure and flexural members, for one embodiment, receive amplified displacements and more effectively dissipate energy. Flexural members restore the structure to the unloaded position. The system does not require moment connections and can work with flexure induced in simply supported beams. The system is highly effective and may remain elastic under maximum considered earthquake ground motions.

摘要： An oscillation damper includes a damper inner pipe with a damper inner pipe wall thickness and a damper inner pipe outer wall. A piston rod and piston are reciprocally movable in the damper inner pipe. The damper inner pipe is divided into a piston-rod-side operating space and an operating space remote from the piston rod. A damper outer pipe has a damper outer pipe wall thickness and a damper outer pipe inner wall. The damper outer pipe is arranged around the damper inner pipe and the damper outer pipe is fluidly connected to the damper inner pipe at the side of the operating space remote from the piston rod. The oscillation damper includes support elements arranged between the damper outer pipe inner wall and the damper inner pipe outer wall wherein the damper inner pipe is at least partially supported with respect to the damper outer pipe.

摘要： A shock absorber includes a push rod, a first piston, a cylinder, a piston rod, a second piston, and a third piston. The cylinder and the first piston cooperatively define a first oil cavity. The second piston, the first piston, and the cylinder cooperatively define a second oil cavity. The third piston and the cylinder cooperatively define a gas cavity. The first piston is configured to urge the hydraulic oil of the second oil cavity to flow into the first oil cavity and the third oil cavity in event the push rod is pushed. The third piston is configured to compress the gas in the gas cavity in event the third piston is urged toward the gas cavity, thereby creating a damping effect.

摘要： A valve assembly for a bicycle suspension system includes a housing, a rotary valve disposed within the housing, and a rotational electro mechanical actuator disposed within the housing. The housing is configured to house shock absorber fluid. The rotational electro mechanical actuator is disposed in operable communication with the rotary valve. The housing, the rotary valve and the rotational electro mechanical actuator define a plurality of fluid flow passages internal to the housing. The rotary valve and the rotational electro mechanical actuator are each subject to contact with or immersion in the shock absorber fluid in the housing when present.

摘要： A jounce control damping system with an elongated housing containing a damping medium, a primary piston assembly, a moveable outer piston assembly, and a movable inner piston assembly disposed at least partially within the outer piston assembly. The primary piston assembly provides a first compression damping force. The inner piston engages the primary piston assembly and provides a second compression damping force when moved in a compression direction. After the inner piston assembly moves a given distance, the outer piston assembly is moved in the compressive direction and provides a third compression damping force.
