Abstract

The chapter delves into the innovative concept of 'digital' pumps for hydrostatic drives, offering a new approach to address the limitations of traditional hydraulic systems. It discusses the history of hydraulic power and the challenges faced by conventional hydraulic drives, such as cavitation and high power losses. The idea of digital hydraulics, introduced by Linjama, is explored in detail, highlighting the benefits of high efficiency, control flexibility, and resilience. The chapter also presents various digital hydraulic valve designs, including parallel digital hydraulic valves and high-speed switching digital hydraulic valves. A key focus is on the variable output control of pump flow and the digital control of variable pumps. The research aims to replace expensive and complex hydraulic systems with simpler and more reliable digital hydraulic components, promising significant cost savings and improved ecological parameters. The chapter concludes by emphasizing the potential of digital hydraulics as a real alternative to traditional servo and proportional systems, while acknowledging the need for further research and development in valve technology and control methods.
