Fluid Power Pumps and Motors
Analysis, Design and Control

Fluid Power Pumps and Motors: Analysis, Design and Controls focuses on the high-performance, axial-piston, swash-plate type machine, providing a thorough analysis of the machine itself and presenting design guidelines for machine components. The book is intended for the engineer building and developing hydraulic systems to help analyze, design, control, and maintain hydrostatic pumps and motors. It also serves as a supplemental textbook. Covers analysis, design, and control considerations of hydrostatic machines' pumps and motors. Example problems illustrate the usefulness of the equations. The most comprehensive and up-to-date book on axial piston machinery. Teaches engineers how to design valve-plates within axial-piston machinery. Considers the variable displacement control problem using transient analysis and modeling. Results and techniques presented reduce product delivery lead-time and costs and increase accuracy of troubleshooting.
