The design of pressure compensators for load sensing hydraulic systems

A clear trend in mobile fluid power systems is to introduce more efficient system concepts, both in terms of energy efficiency and in terms of dynamic behaviour. Load sensing systems offers a very energy efficient solution, but it will also cause interference between the different loads in the system. One way to overcome this problem, is to use pressure compensated valves. The dynamic properties may, however, be problematic and are investigated in this paper.
