The Innas Hydraulic Transformer The Key to the Hydrostatic Common Pressure Rail 2000-01-2561

Through a series of incremental innovations, load sensing (LS) has become the current state-of-the-art in hydrostatic transmission technology. The Common Pressure Rail (CPR) is an alternative way to create a hydrostatic transmission. Although CPR systems offer considerable advantages over LS systems, they never really broke through. The main reason for this was the lack of a good solution to drive linear loads from a common pressure rail. The Innas Hydraulic Transformer (IHT) has been developed to fill this gap. It is a young component but has matured to a stage where a series production within the next two years should be possible. Because of its simple construction, its dynamic capacity, its low control power requirement and its efficiency it can be used to control both linear and rotary loads from a common pressure rail. With the IHT, the potential of CPR systems can finally be unleashed.
