<p>PURPOSE:To simplify the structure of a cylinder assembly and miniaturize the size thereof, by fitting a valve body, which operates in accordance with pressure to open/close fluid passages, in a bulkhead block located between the first and the second cylinders. CONSTITUTION:A valve body 8, which operates in accordance with the variation in pressure to open/close fluid passages 11 and 12, is fitted in a bulkhead block 7 located between the first cylinder 1 and the second cylinder 2. A ram 6, which is connected to a pressure increasing piston 5, is guided to penetrate the valve body 8. With this contrivance, a limit switch or a solenoid valve, which is used to detect the location of a work, can be dispensed with, thereby simplifying the structure of a cylinder assembly, and miniaturizing the size thereof.</p> |
