PURPOSE: A simplified steam pressure cylinder is provided to operate with a high energy efficiency and to increase or decrease steam pressure faster without failure. CONSTITUTION: A steam pressure cylinder is composed of a first forward/backward operating chambers(22,24) formed in front part of a body. A second forward/backward operating chambers(32,34) are formed in rear part of the body. A hydraulic port is formed in rear part of the body to connect the first and second forward operating chambers. A first hydraulic inlet is formed in front part of the body to be connected to the first backward operating chamber. A second hydraulic inlet is connected to the second backward operating chamber. A pilot valve(60) is formed through the first forward operating chamber and the second backward operating chamber.
