Chapter 11 Basic Pneumatic Circuits and Their Application All pneumatic systems are composed of some basic circuits with different function, familiarizing and mastering these basic circuits are necessary foundation for analyzing and designing pneumatic systems. Two-stage pressure control circuit your suggestions  are welcome! One-stage pressure control circuit Over-load protection circuit Force increased circuit by multiple (three here) in-line cylinders Force increased circuit by an air-hydraulic intensifier Impact cylinder circuit * Chapter 11 Basic Circuits and their Application Hydraulic and pneumatic pressure transmission The basic circuit may be classified based on function: pressure and force control , direction control , speed control , etc. One-stage pressure control circuit 1-Pressure meter 2-Pressure switch 3-relief valve a） High and low pressures changeover circuit Pressure difference circuit a) b) Pressure control sequence circuit Over-load protection circuit Force increased circuit by multiple (three here) in-line cylinders Force increased circuit by an air-hydraulic intensifier Impact cylinder circuit Cylinder extending and retracting circuit Cylinder extending, retracting and stop circuit Cylinder extending and retracting circuit a) b) Cylinder extending, retracting and stop circuit Single-acting cylinder one-direction speed control circuit a) Inlet one-direction throttling speed control circuit b) Exhaust one-direction throttling speed control circuit a) Double-direction throttling speed control circuit b) Exhaust throttling speed control circuit Rapid reciprocating movement circuit Speed exchanging circuit Cushioning circuits Air-hydraulic speed changing control circuit Speed changing circuit The End Two-stage pressure control circuit High and low pressures changeover circuit * * * * * Chapter 11 Basic Circuits and their Application
