To sum up, a few design conclusions can be drawn. First of all, it is necessary to formulate a concept of the design solution for a hydraulic gear machine. It is necessary to decide whether the machine is supposed to work as a pump or as a hydraulic motor. It is related to the proper energy transformation in machines. In the case of a pump, the transformation is of mechanical energy into hydraulic energy, and in the case of a motor – the transformation of hydraulic energy into mechanical energy. Next, it is necessary to create a general model of the machine, which allow to carry out the analy­sis of energy transformation in the machine. Finally, it is crucial to decide what types of characteristics describing the transformations and what formulae for the determining of those characteristics should be employed.
