Abstract
The main objective of this Ph.D. thesis is to provide an optimized Flow Sharing Directional Control Valve (DCV shown in Figure 2), specifically developed for maximizing the Energy Recovery opportunities in typical mobile applications. The final goal is the application of the new Energy Recovery architecture on an Off-road machine, in particular on a 5t excavator (Bobcat ZHS 435) that for a series of reasons that later will be explained is the best machine to be tested with this energy recovery layout. In Chapter II a detailed description of the new Directional Control Valve will be explained. In particular, the attention will be focused on its functioning inside the hydraulic circuit. Moreover, the advantages of this new architecture will be described. The experimental and numerical activities will be explained respectively in Chapter III and IV. Finally, in Chapter V the most important energy analysis about this project will be shown.
