Abstract
A valve arrangement includes at least two valves and a housing which is configured as an installation cartridge. One of the valves is configured as a pressure regulator and the other of the valves is configured as a delivery flow regulator. The valve arrangement is configured to be inserted or screwed into a variable-displacement pump, thereby minimizing the spatial requirement of the valve arrangement.
