Abstract
The invention is directed to a pressure reducer wherein the outlet pressure thereof is regulated by means of a comparison of the desired value with the actual value such that the adjusting range is expanded. This expansion of the adjusting range is obtained in that the adjustment of the biasing force of the membrane effects a corresponding adaptation of the desired value applied to a control unit via a position-value transmitter.
