The most important, strategic goal however is creation of the variable displacement version of the new pump PWK. Thanks to full discharge of it's commutation mechanism from hydrostatic forces the variable pump can be directly controlled by low-energy actuator like proportional electromagnet or stepping motor. It means that costly and complicated hydraulic servomechanism (applied in all present variable displacement pumps) is no longer necessary. The new pump may be thus cheaper and lighter than today's units. It allows also to simplify the whole circuit, thanks to elimination of additional pump and it's equipment necessary to supply the servomechanism.
