Claims

[Claims for Utility Model Registration] A first cylinder having a first inner diameter; a second cylinder having a second inner diameter different from the first inner diameter and coaxially aligned with and communicating with the first cylinder; a first piston slidingly fitted within the first cylinder; and a second piston slidingly fitting within the second cylinder and connected to the first piston by a rigid connecting rod; , an inlet for operating high pressure fluid of the first piston is provided at an end opposite to the second cylinder, and the second piston extends from the end of the second cylinder opposite to the first cylinder. a second supply of said or another working high pressure fluid to a predetermined working stroke distance of said second cylinder at a first piston side end of said second piston; an inlet so that after the second piston end reaches the second inlet at the predetermined stroke distance;
An output changing device for an operating cylinder, wherein fluid pressure is also applied to the second cylinder side of the piston, thereby changing the operating force at the output section.
