Abstract
A valve arrangement is disclosed including a housing in which an electromagnetically actuatable preliminary control valve for controlling a differential pressure and a main valve which is actuatable by the differential pressure are arranged and whose closing element provides for a selective connection between an outlet connection and at least one inlet connection. The valve arrangement is adapted for use in automotive vehicles without additional pressure fluid sources, by providing for the main valve to be changed over by means of a movable wall experiencing a balanced pressure in the rest position and which is pressurizable by the differential pressure.
