PURPOSE: An accumulator is provided to increase the moving speed of oil drawn into or out from a cylinder by forming a wide oil passage. CONSTITUTION: An accumulator comprises a cylinder(10), a piston, and a holding part(30). A gas inlet(11) is formed in one side of the cylinder and an opening(12) is formed on the other side thereof. The piston is inserted in the cylinder to reciprocate in the cylinder. The holding part is connected to the opening to restrict the movement of the piston. An oil groove is formed lengthwise on one side of the piston. |
