Influence of New Technologies on Higher Energy Efficiency of Hydrostatic Devices and Systems

Abstract

Both the experience and data from literature show that current hydraulic components and development of electric control systems have significantly increased energy efficiency. Therefore, all world manufacturers of hydraulic devices and systems use advanced technologies and methods with the final aim to integrate them into mechanical system. Energy losses, made as a result of all forms of friction, are minimized. It is safe to say that modern growth is based on development of new materials and accompanying technologies as well as on control techniques, i.e. on mechatronic approach and design of such systems. Ecological requirements and legal regulations should not be neglected, either. Based on the above issues and available data the authors of the paper try to answer the following question: What is the position of once famous factory of hydraulic devices from Trstenik in comparison to other competitive factories worldwide?.
