Abstract (en)
[origin: EP0802328A1] The device has a forcing water pipe (30), a feed pipe (32), connected to forcing water via a floor valve (4), and a ram valve (3), connected to both pipes. The ram valve is held in closing position by a spring, to separate the water pipes. A pressure accumulator (5) is connected to the forcing water pipe in front of the ram valve, in direction of flow. The floor valve element is ring-shaped, axially movable, and connected sealed to the feed pipe. The effective cross section of this connection is larger than that of the valve seat. The valve seats (6, 4a) of ram valve and floor valve are mechanically coupled for transmission of kinetic energy.
