AB - The need for energy savings is on the rise. Pneumatic systems, as essential parts of any branch of industry, are large consumers. The opportunities for saving energy in these systems are great. The paper presents a structure of pneumatic systems while a special emphasis is put on the saving of energy in the execution part with semi-rotary actuator by a method of restoring energy via by-pass valve. The realized energy savings are average 41.48% for conventional systems and 31.42% for servo systems for nominal operating value of pressure supply of 600 kPa. Cost effectiveness of proposed method is also presented.
