Abstract
This paper presents a study the performance and to improve energy efficiency of the traditional pneumatic driver, three supply pressures used 4, 6 and 8 bar, by cutoff flow process occurs at stroke end of the actuator before execution position, in which pressure supply line cutoff and the exhaust line remains open in position specified previously. The piston stroke completes rest under the influence of air expansion , the inertia force of the piston exactly at execution position, that is saving in compressed air and energy, reduced in required air additional to reduce the cost. compared with the traditional control of motion of the asymmetric cylinder in which maximum energy saving obtained at 6 bar are 16.7%.
