Vacuum-Operated Cylinders The cylinders described on this page are vacuum operated and are designed to provide reliable linear movement using differential air pressure. When a vacuum is applied to the front chamber of the cylinder, the integrated piston rod extends by overcoming the opposing spring force. This movement is generated by atmospheric pressure acting on the rear face of the piston, with air entering the rear chamber through the hollow piston rod. The greater the pressure difference between the evacuated front chamber and the atmospheric rear chamber, the greater the piston thrust force. The piston rod returns to its initial...
