Design of Dynamic and Efficient Hydraulic Systems Around a Simple Hydraulic Grid 2002-01-1432

Through the development of the Innas Hydraulic Transformer, a hydraulic driveline called Common Pressure Rail (CPR) becomes possible. The CPR system profits from considerable advantages over conventional hydraulic drivelines in terms of costs, controllability and flexibility. In CPR systems all cylinders and motors are connected to a single common rail, delivering the same pressure to all connected devices. The control of functions is realized using innas hydraulic transformers (IHT). IHTs enable local control of cylinders or motors without throttling energy. Integrating an IHT with a cylinder and closed loop control creates a Variable Displacement Cylinder or VDC. These devices enable modular design of mobile machinery. Design of flexible machines becomes possible and complex machine tasks are easy to automate without increasing the complexity of the machine.
