2112359 9301433 PCTABS00019 A valve arrangement has a valve housing (4) with a valve chamber (12) formed therein, which has an outlet (13) and an inlet (23) which is adapted to be connected to a pressure-medium source (1). A control valve (10, 26) is adapted, when in closed position, to close the outlet (13) of the valve chamber (12) and, when in open position, to open it. A main valve arranged in the valve housing has a valve member which is displaceable in the valve chamber and, depending on the pressure in the valve chamber, is shiftable between an outer closing position and an inner opening position. The valve member consists of a piston (22) freely displaceable in a circular-cylindrical portion (15) of the valve housing (4). The inlet of the valve chamber consists of an annular gap (23) between the piston (22) and the circular-cylindrical portion (15) of the valve housing (4).
