摘要： A hydraulic buffer device includes a first chamber, a second chamber, and a buffering space disposed under the first and second chambers, an air bladder disposed in the buffering space, an oil chamber disposed above the first and second chambers and divided by a piston into upper and lower chamber portions, and an annular passage disposed around the oil chamber. When the piston is moved downwardly within the oil chamber, the hydraulic oil flows from the lower chamber portion into the buffering space via the first chamber to contract the air bladder so that, upon expansion of the air bladder, air pressure in the air bladder pushes the hydraulic oil to flow from the buffering space into the upper chamber portion via the second chamber and the annular passage.
