Abstract
PURPOSE: To allow the operation of a cylinder to carry out in the plural number of stages by a method wherein the process for operating a piston can be set on a plural stage basis by selecting the plural number of pressure fluid injection ports provided in the axial direction of the cylinder.
CONSTITUTION: The plural number of air injection ports 3aW3d are provided along the axial direction in a cylinder 3 in which one main piston 4 and two driving pistons 5, 6 are installed in such a way that these driving pistons, which are concentric and partly overlapped with the main piston, are installed after shifting their positions in an axial direction. The pistons 5, 6 are provided with stoppers 5a, 5b that restrict their strokes, and each of the pistons 4W6 are thrusted to the left by means of a spring 7. If air is injected from the port 3a, the piston 4 is forced to operate the first stage stroke. Then, if air is injected from the ports 3c and 3d, the piston is forced to operate the second and third stage strokes, respectively.
