<p>A valve arrangement comprises a valve housing (4) which has a valve chamber (7, 13, 15) with an outlet (9, 10, 11, 12) and an inlet (16) which is adapted to be connected to a pressure-medium source (25), and a valve opening communicating with the valve chamber. A control valve (8, 22) is mounted on the valve housing (4) to close the outlet of the valve chamber when in closed position, and open this outlet when in open position. A main valve (14, 17) mounted on the valve housing (4) has, in the valve opening, a valve member (17) which is movable in response to the pressure in the valve chamber (7, 13, 15) between an outer closing position and an inner opening position. The inlet (16) of the valve chamber extends through the wall of the valve housing (4).</p> |
