PROBLEM TO BE SOLVED: To provide a variable volume controller for pressurized fluid capable of taking out predetermined amount of fluid to the outside while maintaining predetermined pressure of fluid in fluid equipment and pouring only predetermined amount of fluid into the fluid equipment while maintaining predetermined pressure for the fluid equipment requiring change of amount of fluid existent in the equipment arbitrarily. SOLUTION: This variable volume controller is provided with a cylinder part provided with a flow-out inlet for fluid, a piston part sliding in the cylinder part, a positioning member for positioning the piston part at a predetermined position, a driving source for driving the positioning member, and a controller for controlling the driving source. The driving source for driving the positioning member is controlled to position the piston part sliding in the cylinder part at the predetermined position and control volume of pressurized fluid existent in the fluid equipment.
