PURPOSE: An accumulator is provided to maintain the constant internal pressure of a cylinder by controlling the position of a detecting part with a detector control part according to the changed internal pressure of the cylinder. CONSTITUTION: An accumulator(10) comprises a cylinder(30), a piston(50), a piston rod(55), a detector(70), and a detector control part(100). The piston is arranged inside the cylinder. The piston rod is coupled to one side of the piston. The detector detects the operation range of the piston rod to detect the position of the piston rod. The detector control part is coupled to the detector and moves the detector within the operation range of the piston rod according to the internal pressure of the cylinder. |
