Accomplished authors and researchers Andrea Vacca and Germano Franzoni begin by describing the foundational principles of hydraulics and the basic physical components of hydraulics systems. They go on to walk readers through the most practical and useful system concepts for controlling hydraulic functions in modern, state-of-the-art systems.\u003c\/p\u003e\u003cp\u003eWritten in an approachable and accessible style, the book's concepts are classified, analyzed, presented, and compared on a system level. The book also provides readers with the basic and advanced tools required to understand how hydraulic circuit design affects the operation of the equipment in which it's found, focusing on the energy
