Method and device for cleaning conduits, in particular supply conduits in pneumatic brake systems

The method involves pumping a cleaning liquid with a supply pressure of 0 to 5 bar through the cleaning pipeline (2), and supplying air with a pressure of 0.5 to 2.0 bar to the cleaning liquid flowing to the cleaning pipeline. The cleaning liquid is blown with compressed air to the cleaning pipeline at the end of a cleaning operation. An independent claim is also included for a device for cleaning pipelines, particularly supply lines in a pneumatic brake system.
