摘要： A rotary damper has a damper body having a receiving portion, and a rotor rotatably disposed in the receiving portion of the damper body. A space between an inner circumferential surface of the receiving portion and an outer circumferential surface of the rotor is divided into a plurality of pressure chambers. A rotation speed of the rotor is controlled to be at a low speed by a flow resistance of fluid filled in each of the pressure chambers when the fluid flows through gaps between an inner surface of the receiving portion and an outer surface of the rotor opposed to each other in a direction of a rotation axis of the rotor. The damper body and the rotor are relatively movable in the direction of the rotation axis of the rotor.

摘要： A damping shaft mechanism has a spiral shaft, spiral guide bush, a shell and blade. An external spiral structure is arranged at one end of the spiral shaft, and its core has a cone segment. An internal spiral structure is arranged in the spiral guide bush, which cooperates rotationally with the external spiral structure so that it can move along the axis relative to the spiral shaft when the spiral shaft is rotating. The two cavities change size by moving the spiral guide bush driven by the spiral shaft in the shell, and the taper on the spiral shaft makes the fit clearance between the spiral shaft and the spiral guide bush changed from maximum to minimum gradually in the damping process, so that the oil-flowing section between the two cavities changes from big to small.

摘要： A piston connected with a piston rod is fitted in a cylinder having a hydraulic fluid sealed therein. A damping force is generated through extension and compression disk valves and an orifice. Vehicle height adjustment is performed with a self-leveling mechanism by transferring the hydraulic fluid between the cylinder and a hydraulic fluid tank. A bladder of the hydraulic fluid tank is clamped between an outer flange portion of a partition member and a casing. Because the hydraulic fluid tank is formed without welding, it is possible to avoid contamination of the hydraulic fluid by welding sputter and thermal deformation. Provision of an O-ring on the outer flange portion can reduce the pressure acting from a reservoir on the clamped portion of the bladder and hence prevent dislodging of the bladder.

摘要： A fluid filled type vibration damping device including: a partition member having a communication passage connecting a pressure receiving and equilibrium chambers; an obstructing rubber elastic plate juxtaposed against the communication passage from an equilibrium chamber side, adapted to obstruct the communication passage, and arranged to be exposed to pressure of the pressure receiving and the equilibrium chamber at both faces; and a constraining member provided for retaining an outer peripheral section of the obstructing rubber elastic plate in contact against the partition member at multiple locations. The constraining member provides an opening/closing control member operated to induce the obstructing rubber elastic plate to push against the partition member and close off the communication passage, and to induce elastic deformation of the obstructing rubber elastic plate to be separated from the partition member.

摘要： The rotary damper for controlling helicopter motions includes an outer canister with an inner paddle wheel receiving cavity which receives an inner paddle wheel with upper and lower elastomeric tubular intermediate members between the inner paddle wheel and the outer canister. The canister and inner paddle wheel form neighboring variable volume chambers in liquid communication through liquid damping conduits. A clockwise rotation of the inner paddle wheel about the center of rotation axis relative to the outer canister pumps damper liquid from a second variable volume chamber through a first liquid conduit towards a first variable volume chamber, and a counterclockwise rotation of the paddle wheel relative to the outer canister pumps the damper liquid from the first variable volume chamber through the first liquid conduit towards the second variable volume chamber with the elastomeric tubular intermediate members providing for the relative rotation and containing the damper liquid in the damper.

摘要： A steering damper comprises two oil chambers (R1, R2) delimited in a housing (1, 7) by a partitioning member (2, 8), and a damping valve (2a, 2b) which imposes a drag on a flow of working oil between the two oil chambers (R1, R2). By further comprising an oil passage (5) connecting the two oil chambers (R1, R2), a pair of check valves (5a, 5b) which prevents oil flow from each of the two oil chambers (R1, R2) into the oil passage (5), and a bypass passage (6) connected to the oil passage (5) between the pair of check valves (5a, 5b) and having an opening that opens onto the interior of the housing (1) in the vicinity of the neutral position of the movable partitioning member (2, 8), the steering damper enables the movable partitioning member (2, 8) to return quickly towards the neutral position.
