This reprint focuses on the recent advances in fluid power technology reporting results in a wide range of applications. Studies concerning the developments of pumps both at constant and variable displacement are reported. Analyses are focused on the improvement of efficiency, control, design and pressure ripple reduction. About fluid power, several applications are investigated with the aim of reducing energy losses, in particular implementations in an excavator, a hybrid transmission and a system for agricultural solutions are described. Applications are studied focusing also on the effects of a particular load holding valve, and facing the relevant aspects of the condition monitoring, failure modes and effects analysis. The fluid power covers a very wide range of application as demonstrated by the paper concerning an exoskeleton device. Finally, a particular application concerning a gas pressure regulator with lower noise emission is reported.

This book covers some of the fundamental topics in fluid power technology, presenting detailed derivations of formulas that form the basis of the theory. It shows the reader how to properly (i) design basic fluid power systems, (ii) construct lumped parameter models of simple fluid power systems, (iii) perform frequency analysis of fluid power components and systems, and (iv) develop controllers for fluid power systems. The book mainly focusses on mathematical modelling and analysis of fluid power components and systems i.e. practical issues such as working principles and construction of components are not covered in depth. The text is organized in four main parts: I Physics of Fluid, II Fluid Power Components, III Fluid Power Systems and IV Learning by Doing. .

Water is fundamental to human life, and the ways in which a society uses it can tell us a great deal about a people. The ancient Greeks and Romans had at their disposal several mechanical water-lifting devices. The water-screw, the force pump, the compartmented wheel, and the bucket-chain were developed by scientists associated with the great school at Alexandria. Application of these devices was sporadic in the Hellenistic world, but they, and the later saqiya gear, were used in a wide range of rural and urban settings in many parts of the Roman Empire.Professor Oleson has prepared a definitive study of mechanical water-lifting devices in the Greek and Roman world. He systematically and thoroughly examines the literary, papyrological, and archaeological evidence for the devices and considers the design, materials, settings, costs, effectiveness, and durability of the many adaptations of the small basic repertoire of models. The literary and papyrological materials range from Deuteronomy to papyri of the seventh century AD, and the archaeological sites discussed range from Babylon to Wales.An extensive collection of illustrations complements the literary, papyrological, and archaeological evidence for this remarkable ancient technology.
