Abstract

1. A method for supplying a pressurized medium, preferably an injection medium, to at least one consumer site, preferably an injection site, at a pressure not exceeding a reference value, comprising moving the pressurized medium at varying pressure by means of a regulatable pump device, and generating measuring value signals from the momentarily prevailing pressure of the pressurized medium, characterized by the fact that the maximum pressure value arisen within a predetermined time interval is determined from the measuring value signals within said interval, that an actual value is derived from that pressure value and a comparison value derived from at least one maximum value for a preceding time interval which has been determined in the above mentioned manner, and that regulation signals for the pump device are generated by virtue of a comparison of the actual values and a reference value.
