Excavator hydraulic circuit solution to reduce dissipations and fuel consumption

In the field of mobile machine research is mainly focused on solutions to reduce energy dissipations and fuel consumptions being these machines equipped with Diesel engines. This paper presents a solution for improving performance traditional Load sensing flow sharing circuit. The concerns insertion signal conditioner (LSc), developed by Walvoil S.p.A., that permits dynamically change pressure drop across directional valves. A careful control this new component obtain reduction consumption without changing taking as reference JCMAS duty cycle. mathematical model 9 ton excavator was previously validated tests carried out both single hydraulic main components like pump LSc added circuit has permitted simulate saving achievable in comparison solution. relevance carefully device order maximize performance. physical prototyping been already will be installed confirm simulated
