    摘要: A variable force cylinder device with a piston (20) reciprocated by a pressurized fluid in a cylinder chamber (18), in which the piston (20) has a large-diameter portion (34) and a small-diameter portion (36), the cylinder chamber (18) has a large-bore portion (30) corresponding to the large-diameter portion of the piston (34) and a small-bore portion (32) corresponding to the small-diameter portion of the piston (36), and a variable force mechanism is provided for varying a pressure-receiving area of the piston (20) under an interaction of the piston (20) with the cylinder chamber (18) varying depending on the phases of the piston stroke.
