Abstract

This paper presents a structure of a compressed air saving for pneumatic positioning systems with capacity to move high loads. These structure uses the loads to save compressed air and thus increase the energetic efficiency of this systems. This configuration adds a fast switching on/off valve in a feedback between the cylinder chambers. With this type of configuration up to 58 % of compressed air saving can be achieve
