Three piston rods are arranged, each of the piston rods is supported by a rod cover screwed onto the open end of each cylinder, and the pressurizing passage on the piston side is connected to the first piston rod.
A flow path further branches from the piston side, faces the second piston side, and further passes through the second piston toward the third piston, and the other flow path connects the oil flow ports of the first cylinder and the third cylinder. A hydraulic constant-velocity cylinder characterized in that the oil flow port facing the tank and the second cylinder are communicated with the tank side and the pressurizing flow path side via a differential pressure valve.
