Beschreibung
Zusammenfassung:	A pressure control device to be inserted into a connection between a front wheel brake and a rear wheel brake which determines the rear brake hydraulic pressure in dependence upon front brake hydraulic pressure. The pressure control device provides a plurality of valve pistons hydraulically connected in parallel and displaceable by front axle hydraulic pressure in opposition to a control force. A predetermined change-over hydraulic pressure develops a braking pressure in the rear brake which is less than the front brake pressure. The valve pistons are provided by stepped pistons guided within stepped bores, each of which pistons provides smaller and larger effective pressure surfaces.
