摘要： A hydraulic damper (3) includes a tube (4), a piston assembly (5) disposed slidably inside the tube (4), and an additional valve assembly (13). A compression chamber (9) is defined between the piston assembly (5) and the additional valve assembly (13). An additional compensation chamber (14) is defined between the additional valve assembly (13) and one side of a slideable partition (10). A gas chamber (11) is defined at the other side of the slidable partition (10). The damper includes an additional chamber assembly (15) to retain all the advantages of a twin-tube damper while providing the single construction offered by a mono-tube damper. One end of the additional chamber assembly (15) is attached to the slidable piston chamber (5) or to said piston rod (6) at the compression side thereof and the other end of said additional chamber assembly (15) is terminated with the additional valve assembly (13).

摘要： In a hydraulic shock absorber, upper and lower pistons (26, 27) forming upper and lower two stages are fixed to a leading end portion of a piston rod (23). An intermediate oil chamber (21C) is provided between the upper and lower pistons (26, 27). An intermediate air chamber (60) is provided in such a manner as to compensate an oil amount change in an oil chamber (21) by coming into contact with the intermediate oil chamber (21C) and expanding and compressing on the basis of the oil amount change of the oil chamber (21) caused by an extension and compression stroke of the piston rod (23), and an air compression rate of an upper portion air chamber (22B) of the oil reservoir chamber (22) is set to be equal to or more than an air compression rate of the intermediate air chamber (60), with respect to the extension and compression stroke of the piston rod (23).

摘要： A frequency- dependent damper (10) for creating a damping force in response to a variable - frequency disturbance includes an outer damper body (12) having an internal cavity (16), an inner damper body (14) for receiving the variable - frequency disturbance extending into the internal cavity, a first fluid chamber (46) and a second fluid chamber (48) defined inside the internal cavity, a piston (44) separating the first and second fluid chambers, a selected orifice ( 39 ) for transferring fluid between the first and second fluid chambers, and a selected spring element (54) arranged serially between the piston and the inner damper body such that the piston can move relative to the inner damper body through deformation of the spring element.

摘要： A shock absorber comprises a tubular housing (10), a bearing (14) sealingly mounted to the front end of the tubular housing, a piston (34) mounted within the tubular housing (10) for a reciprocal sliding movement, which defines within the tubular housing (10) a working chamber (W) and an accumulator chamber (A), a stem (32) being connected to the piston (34) and projecting from the tubular housing (10) through the bearing (14), at least one fluid pathway (42) connecting the working chamber (W) to the accumulator chamber (A), and a compensation diaphragm (18) facing on the accumulator chamber, which consists of a sleeve made of a deformable material mounted between the ends of the bearing. The compensation diaphragm has a rear end (18b) folded backwards such as to envelope the cupshaped rear end (14b) of the bearing (14), and provided with a shaped edge (18c) to provide a sealing between the bearing and the piston stem.

摘要： The invention relates to a method for controlling the pressure balance between the two chambers (2a, 2b) in a shock absorber and to a shock absorber of this kind. The shock absorber consists of a damping cylinder (2) pressurized by a system pressure (p3) and divided by a piston (3) into a compression and a return chamber (2a, 2b), in which a resilient device (8) is disposed in the return chamber (2b). The resilient device (8) comprises a pressurizing member (9) or pressurizing medium disposed in an inner volume (8a, 33) which is delimited from the return chamber (2b). The resilient device (8) acts upon the damping medium volume in the return chamber (2b), so that the pressure (p2) initially during a compression stroke does not fall below a predetermined minimum pressure. As long as the pressure (p2) in the return chamber (2b) is less than the pressure created by the resilient device (8), the device is energy-absorbing. When the pressure in the return chamber (2b) is greater than the pressure created by the resilient device (8), the device becomes inflexible. This resilient device therefore compensates for the pressure reduction in the return chamber (2b) which occurs under rapid damping movements and can cause cavitation during a compression stroke.

摘要： The present invention relates to a shock absorber, in particular for vehicles, having a damping force control valve for controlling a magnitude of a damping force generated by a movement of a piston to a target value, wherein a damping force setting means is configured to vary the target value depending on a change in a moving speed of the piston.
