The second edition of this introductory book presents the principles of hydrostatic transmissions. The basic concepts of typical open-circuit and closed-circuit HSTs are described in a simple-to-understand manner. The configurations, types, specifications, and applications of HSTs are also given. Appendix 2 contains case studies on an open-circuit hydraulic concrete pump system, a hydraulic steering system, and typical displacement controls of a bidirectional variable-displacement axial-piston pump. Appendix 4 describes basic displacement control methods of variable-displacement axial-piston pumps. The book uses the SI system of units. Hydrostatic transmissions (HSTs) occupy a distinct place in fluid power technology. They are widely used in agricultural tractors, on and off-highway mobile equipment, and various self-propelled equipment for the transfer and control of power. An HST provides an infinitely variable speed between zero and maximum in both forward and reverse modes of operation without changing the prime mover's speed. Moreover, manufacturers are bringing out smaller, lighter HSTs with advanced electronic controls and improved performance. These factors make HSTs a cost-effective choice for many industrial and mobile applications.
When designing hydraulic systems, you aim to get as much work done as possible while using less energy. You've got many design choices - from more traditional circuits to specialized arrangements like load sensing. High-end load sensing hydraulic systems offer better control and energy efficiency. Load sensing systems have become increasingly popular and widely accepted, introducing greater sophistication and simplicity in hydraulic controls. The book is really helpful when it comes to understanding load sensing hydraulic systems. It explains these systems' important components, like load sensing variable-displacement pumps and pump displacement control elements. When the system demands flow, a load sensing variable-displacement pump with a swash plate design delivers only the flow required by the associated system at a pressure required to move the connected load. The displacement control elements, including pressure controllers and load sensing compensators, are used to control the swash plate angle efficiently. For easy understanding, the book provides simple examples that clearly illustrate different modes of operation for load sensing systems. The SI system of units is employed throughout the book.

Initially, cartridge valves were designed to perform a single function, and a cavity was created to accommodate the valve. Over time, the technology evolved to include multifunction and integrated circuit features, with many cartridge valves incorporated into a single manifold block. In recent years, there have been numerous advancements aimed at reducing leakage, complexity, and size, while improving the reliability, efficiency, and cost-effectiveness of cartridge valves.
