Abstract:
The invention relates to a cover device for at least sectional closing of an underwater opening in a hull of a watercraft, in particular an opening of a transverse channel of a thruster. According to the invention the cover device includes at least one variable-volume hollow chamber lip including at least one buoyancy body, and the at least one hollow chamber lip is shiftable into an expansion state or into a shrinkage state by supplying or removing a fluid, in particular air. As a result of the variable-volume or inflatable cover device a more reliable and simultaneously lower-maintenance operation of the cover device is given. In addition, the invention has a thruster, in particular a bow or stern-thruster, as subject matter.

Claim (Index 6):
The cover device according to  claim 5 , wherein a change between the expansion state of the hollow chamber lip is effected rapidly due to the bistable spring element and wherein the shrinkage state of the hollow chamber lip is also effected rapidly due to the bistable spring element.
