摘要： The derailleur has a damper that breaks the angular movements of a chain guide. Variable volume chambers in the damper are filled with a damping fluid and connected through a controlled fluid passage system so that fluid flows between chambers in response to angular movement of the chain guide. The damper comprises a dividing body in a mobile body coaxial to the axis X, mechanically constrained so that each rotation of the dividing body about the axis X is accompanied by a translation of the dividing body along the axis X. The dividing body is mechanically constrained to the chain guide and moves with it in the angular direction about the axis X. The chambers are formed in the mobile body on opposite sides of the dividing body and change volume in opposite directions when the dividing body moves along the axis X.

摘要： A damper, including: a tube body, a central spindle, and two laminae. The laminae each include a curved plate, an oil-sealing rib plate and an oil-discharging rib plate which are disposed at two ends of the curved plate, respectively. The inner wall of the tube body is provided with two convex splitters. One end of the central spindle is inserted into an inner chamber of the tube body and sealed in the tube body; the other end of the central spindle extends outside the tube body. The central spindle includes two ribs, and the laminae are disposed between the ribs and the tube body. The ribs, the laminae and the splitters combined divide the inner chamber of the tube body into two pressure chambers and two nonpressure chambers; both the pressure chambers and the nonpressure chambers are filled with damping oil.

摘要： A swiveling arrangement with a swiveling element swivelable around an axis powered and damped by a gas spring having a cylinder filled with gas and divided into first and second working chambers by a piston that has a piston rod guided through the second working chamber and a guiding and sealing unit. A first connection opened during an outward stroke of the piston from the second to the first working chamber, and a second connection is opened during an inward stroke from the first to the second working chamber that has a smaller cross-sectional flow area than the first connection. An auxiliary piston separates the second working chamber from an auxiliary chamber. A third connection from the auxiliary chamber to the second working chamber opened in the end move-out stroke and a fourth connection from the second working chamber to the auxiliary chamber opened in the move-in stroke.

摘要： The present invention relates to a suspension method and to a shock-absorbing device for an automobile in the broadest sense of the term, i.e. any vehicle having a suspension and moving under its own power. Said shock-absorbing device includes a damping assembly (1) having, on the inside thereof, a piston (2) connected to a rod (17), the piston (2) and the rod (17) combined therewith being movable, in both the compression and expansion direction, about a static position inside the damping assembly (1) in order to provide a shock-absorbing function, the inside of the damping assembly (1) being filled with a hydraulic fluid, characterized in that said assembly (1) engages with a means for varying the damping effect so as to produce: a compression phase consisting of a compression sub-phase, directed from the static position toward the maximum compression position of the piston (2), and of an expansion sub-phase, directed from said maximum compression position toward the static position, respectively, and an expansion phase consisting of an expansion sub-phase, directed from the static position toward the position of maximum expansion of the piston (2), and of an expansion sub-phase, directed from said maximum position toward the static position, respectively, the means for varying the damping elect controlling the damping assembly such that the damping value of the compression sub-phase of the compression phase and/or the expansion sub-phase of the expansion phase is different from the damping value of the expansion sub-phase of the compression phase and the compression sub-phase of the expansion phase, respectively. According to the invention, provided is a step of modifying the damping value with separate values for the compression direction as well as for the expansion direction for each of the work sectors of the shock absorber depending on whether the work is being carried out between the static position of the suspension and the fully compressed position, or between the static position of the suspension and the fully expanded position.

摘要： A buffering device includes a cylindrical casing and a piston module movably mounted in the cylindrical casing. The cylindrical casing includes a base plate and a shielding piece pivotally attached to the base plate. An air inlet and an air outlet are defined in the base plate. A diameter of the air inlet is greater than that of the air outlet. When the piston module is moving towards the base plate, the shielding piece is rotated to a closed position to shield the air inlet by air pressure above the shielding piece. When the piston module is moving away from the base plate, the shielding piece is rotated to an open position to expose the air inlet by environmental air pressure.
