Abstract: In order to attain a modestly dimensioned device with small height, comprising two pressure regulators for supplying two independently regulated adjustable pressures from line pressure, the two regulators are divided into two functional units arranged laterally side by side. The first unit comprises a first valve chamber, the second unit a second valve chamber which act together to regulate the output pressure with manually adjustable control means. Line pressure supply line and pressure issue line of each unit are arranged in line with said valve chambers arranged side by side. The issue lines are connected to a measurement selector switch by which each of the units can be connected separately with measurement means. Further, independent measurement connections are provided. The described arrangement allows a compactly formed device in a box-shaped block.
