Abstract

The invention relates to a method for controlling the pressure supply of a hydraulic piston-cylinder unit (18) which is connected to a pressure source (11), which carries out a working step which terminates when a predeterminable amount of a displaced fluid pressure medium is not attained during a charge stroke of the piston-cylinder unit (18).
