Description

two pressure equalization systems with remote The F i g. 2 shows an arrangement in which to

operable closure devices arranged 60 reduction of the pressure peaks on the outer skin 1 of the be, of which the channel parts 5 from the outer skin 1 to the ship for the respective direction of travel effective pressure equalization system is opened. matching places under the ship's bottom 6 each

In the known arrangements, the installation is at least on the side of their mouths in the outer skin one can be passed through the entire width of the ship.

Another solution to the problem of the invention is that each of an orifice outgoing channel part of the pressure equalization channel device at a point in the ship's bottom on the 35 side of its mouth ends, which sat a pressure equalization. The invention relates to a cross-flow control for this type of construction has the same ones mentioned above Watercraft with a control water channel and advantages and is particularly suitable for ships with shallow a pressure equalization channel device whose Mün-Boden is suitable. fertilize in the outer skin of the watercraft 40 Further details of the invention are at hand are ordered. of the configuration shown schematically in the drawing El is an arrangement of one or more pressure management example explained, namely shows
