The Working Hydraulics of Valve-Controlled Mobile Machines: Classification and Review

Abstract Productivity, reliability, controllability, flexibility, and affordable costs represent key aspects in mobile machines. Additionally, due to the high fuel price and the introduction of stringent emission regulations for diesel engines, the reduction of fuel consumption while persevering the existing performance is the current demand. In order to satisfy and maximize the above requirements, different hydraulic system architectures have been developed during the last decades. Both academia and industry have been investing considerable resources delivering numerous outcomes that require a classification. This review paper closes this gap by analyzing and classifying the working hydrau…
