摘要： A shock absorber has a cylinder tube coaxially arranged with a strut tube for defining therebetween an annular reservoir chamber and an upper reservoir chamber which is separated from the annular reservoir chamber. A first fluid path is defined for permitting fluid flow from a lower fluid chamber in the cylinder tube to an upper fluid chamber and the annular reservoir chamber in response to bounding stroke of vibration. A second fluid path is also defined for permitting fluid flow from the lower fluid chamber and the annular reservoir chamber to the upper fluid chamber and the upper reservoir chamber, in response to rebounding stroke of vibration. A first flow restriction means is disposed in the first path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics. A second flow restriction means is also disposed in the second path for generating damping force in response to bounding stroke of vibration, which damping force is variable depending upon the magnitude of the bounding stroke in essentially linear variation characteristics.

摘要： A variable-damping-force shock absorber such that the damping force determined through an orifice selected by an orifice adjuster according to the driver's preference can further automatically be increased during extension for improvement in road-holding ability and decreased during compression for improvement in riding comfort. The shock absorber according to the present invention comprises an annular member formed with an orifice and a disk valve disposed on top of the annular member. During extension, the disk valve is closed for allowing fluid to by-pass through an orifice of the annular member; during compression, the disk valve is opened for additionally allowing fluid to by-pass through the annular member. Further, since the various elements for adjusting the damping force are completely housed within the piston rod, it is possible to increase the stroke of the piston rod.

摘要： A variable-damping-force shock absorber in which the motor for rotating the orifice adjuster is housed within the cylinder and the orifice-adjuster position sensor for outputting binary coded sensor signals is incorporated. Therefore, it is possible to reduce noise generated from the motor while improving the lifetime of the motor because mud or rain water will not adhere onto the motor and to improve the precision and the response speed in rotating the orifice adjuster because the adjuster can be feedback controlled in digital fashion. Further, since the driven shaft of the motor or the reduction gear is loosely coupled with the orifice adjuster in the axial direction thereof, it is possible to reduce the torque or the size of the motor, because fluid pressure is not directly applied to the driven shaft via the orifice adjuster.
