An oil cooling and filtering circuit connecting a reciprocating fluid power hydraulic cylinder to a reversible hydraulic pump or hydraulic directional valve. In the print head, ink supply ports are arranged on both sides of a plurality of channels. The tracking unit obtains an object parameter of the object, wherein the object parameter is associated with a movement of the object. The cylinder is evacuated to a pressure which does not exceed 10% of ambient pressure during operation of the device, so that pressure changes in the low pressure region have minimal effect on the compensation force during movement of the movable member over its displacement range.
