This exciting reference text is concerned with fluid power control. It is an ideal reference for the practising engineer and a textbook for advanced courses in fluid power control. In applications in which large forces and/or torques are required, often with a fast response time, oil-hydraulic control systems are essential. They excel in environmentally difficult applications because the drive part can be designed with no electrical components and they almost always have a more competitive power/weight ratio compared to electrically actuated systems. Fluid power systems have the capability to control several parameters, such as pressure, speed, position, and so on, to a high degree of accuracy at high power levels. In practice there are many exciting challenges facing the fluid power engineer, who now must preferably have a broad skill set.

The use of hydraulic control is rapidly growing and the objective of this book is to present a rational and well-balanced treatment of its components and systems. Coverage includes a review of applicable topics in fluid mechanisms; components encountered in hydraulic servo controlled systems; systems oriented issues and much more. Also offers practical suggestions concerning testing and limit cycle oscillation problems.

Fundamentals of hydraulics and pneumatics are presented in this manual, prepared for regular navy and naval reserve personnel who are seeking advancement to Petty Officer Third Class. The history of applications of compressed fluids is described in connection with physical principles. Selection of types of liquids and gases is discussed with a background of operating temperature ranges, contamination control techniques, lubrication aspects, and safety precautions. Components in closed- and open-center fluid systems are studied in efforts to familiarize circuit diagrams. Detailed descriptions are made for the functions of fluidlines, connectors, sealing devices, wipers, backup washers, containers, strainers, filters, accumulators, pumps, and compressors. Control and measurements of fluid flow and pressure are analyzed in terms of different types of flowmeters, pressure gages, and values; and methods of directing flow and converting power into mechanical force and motion, in terms of directional control valves, actuating cylinders, fluid motors, air turbines, and turbine governors. Also included are studies of fluidics, trouble shooting, hydraulic power drive, electrohydraulic steering, and missile and aircraft fluid power systems. Illustrations for explanation use and a glossary of general terms are included in the appendix.

The excitement and the glitz of mechatronics has shifted the engineering community's attention away from fluid power systems in recent years. However, fluid power still remains advantageous in many applications compared to electrical or mechanical power transmission methods. Designers are left with few practical resources to help in the design and

This book forms the Proceedings of the Second Symposium on Fluid Power organised by the Japan Hydraulics and Pneumatics Society and held in Tokyo in September 1993. It follows the very succesful First Symposium held in 1989 and presents the latest information on research and industrial activity currently underway in the field of fluid power.

This book covers the background theory of fluid power and indicates the range of concepts needed for a modern approach to condition monitoring and fault diagnosis. The theory is leavened by 15-years-worth of practical measurements by the author, working with major fluid power companies, and real industrial case studies. Heavily supported with examples drawn from real industrial plants – the methods in this book have been shown to work.
