EXPLANATION OF AIR CYLINDER TIMING SEQUENCE DIAGRAMVALID FOR CG-<strong>030</strong> AND ALL AIR DRIVEN RECIPROCATING PUMPSFIGURE 1In this picture, air is entering the cylinder through Port B, driving the piston forward,while exhaust air is exiting from Port A through the timing valve (1). While in motion, theair pressure at pilot ports (4) and (5) is equal to line air pressure.FIGURE 2In Figure 2, the piston has traveled to its fully extended len<strong>gt</strong>h and engaged poppetvalve (2), allowing the escape of a small amount of air from the pilot system. Release ofthis air has reduced the air pressure at timing valve pilot port (5), resulting in a pressureimbalance, causing the timing valve spool to shift, directing drive air through Port A,reversing direction of piston travel.FIGURE 3As the piston rod retracts, air pressure in the pilot system is again equal to linepressure, and exhaust air is expelled from the rear of the cylinder through Port B whiledrive air is entering the cylinder through Port A.FIGURE 4The piston has reached its maximum retraction travel and engaged poppet valve (3),resulting in a reduction of air pressure at pilot port (4). This causes the timing valvespool to shift, directing drive air to the cylinder through Port B. The piston is now movingforward again as exhaust air exits the cylinder through Port A.®
