Abstract: The invention provides a fluid buffer with adjustable damping coefficient, it includes: cylinder tank which has a placing space, the placing space is filled with fluid; piston which is equipped with piston head moving in the placing space and the piston bar extending from the piston head to two ends of the tank body. The piston head is equipped with at least one fluid channel passing through the piston head and the piston head consists of at least one piston discs. The piston disc includes: the disc plate which is equipped with the via hole forming the fluid channel; the valve which is installed on the disc body and can be moved from the first position opening the via hole to the second position closing the via hole, and vice versa; the driver which controls the movements of valve through the deformation of from memory alloy, thereby opens or closes said fluid channel to adjust the number of damping force. Due to the valve in buffer of the invention is driven by form memory alloy, so the leaning on the outer force is eliminated, so the reliability of the buffer is maintained.
