Abstract
The invention is directed to a pressure reducer having an outlet pressure which is controllable via a desired value-actual value comparison. The desired value of the outlet pressure is selectable in a simple manner and can be maintained independently of changes of the through-flow or input pressure. This result is achieved by providing a regulating element equipped with a drive device. The control unit is connected to the drive device for actuating the regulating element by means of a regulating control signal determined from the comparison between the desired value of pressure and the measured outlet pressure.
