Abstract

A valve arrangement includes a valve housing having a circular cylindrical portion in which is formed a valve chamber, a control valve and a valve member. The valve chamber has an inlet adapted to be connected to a pressure-medium source for allowing pressure-medium to flow into the valve chamber and an outlet through which pressure-medium flows out of the valve chamber. The control valve is movable between a closed position in which the outlet of the valve chamber is closed and an open position in which the outlet of the valve chamber is open. The valve member is freely displaceable within the circular cylindrical portion of the valve housing based on the pressure within the valve chamber. The valve member includes a piston which is movable between a closing position in which the piston is adapted to prevent the flow of pressure-medium and an opening position in which the piston is adapted to permit the flow of pressure-medium. The inlet of the valve chamber is defined by an annular gap formed between the piston and the circular cylindrical portion of the valve housing.
