Abstract
A tire pressure control system having a pressure switch installed in a rim, which pressure switch, as part of a tuned circuit, damps, across an air gap, an HF transmitter, installed in a wheel web and having downstream analysis electronics, the pressure switch having a diaphragm pressure cell with a reference pressure, the diaphragm of which reference cell is subjected on one side to the reference pressure and on the other side to the tire pressure. A valve installed in the pressure switch makes it possible to adjust the reference pressure so that, when filling the tire, the desired tire pressure is simultaneously retained as the new reference pressure in the diaphragm pressure cell for the tire pressure control system.
