摘要：<p>An impulse valve has a housing provided with a working chamber and a main piston movable in the working chamber; two preliminary control valves are electromagnetically operated for a short period to switch over the main piston into a selected switching position which is retained even if the preliminary control valve is deenergized. To reduce volume of the valve and to reduce manufacturing cost, a flexible diaphragm is arranged between the preliminary control valves and the main control valve and cooperates with two opposite valve seats in such a manner as to establish connection between an inlet port to the working chamber and alternatively to pressure-relieve the working chamber.</p>
