  • each cavity of the cover is arranged at one end, and in that at the other end of the cavity on the liquid-facing side of the cover a ventable valve, which opens into the environment and opens into the environment and a connection for the compressed gas source is provided.
  • the features according to the invention make it possible to find sufficiency with relatively small and low-power compressed gas sources. It has been shown that it is possible to find a solution with a stronger household vacuum cleaner as a compressed gas source for operating a cover for a medium-sized swimming pool.
  • a plurality of cover elements are provided, each of which has two or more cavities formed by preferably elongate boxes, which are connected to one another via a plate or a web, the free of which faces away from the liquid Side is preferably coated with a material with good absorption properties or the plate is made of such a material.
  • a particularly advantageous embodiment of a cover element is characterized in that the cover element has two or more hollow boxes which are connected to one another via two plates, one consisting of transparent, preferably crystal-clear material and the other on its side facing the transparent plate being well absorbent Surface.
  • the cover element has two or more hollow boxes which are connected to one another via two plates, one consisting of transparent, preferably crystal-clear material and the other on its side facing the transparent plate being well absorbent Surface.
  • the cover element is made of a material with a greater specific weight than the liquid to be covered, as a result of which there is no need to apply balast to enable lowering.
  • a further embodiment of cover elements which enables a particularly extensive reduction of the radiation losses of a swimming pool at low air temperatures, is characterized in that each cover element has a plurality of cavities formed by boxes with flood openings, which are connected to one another via at least one web, preferably in one piece are, two groups of boxes are provided and the boxes belonging to each group are connected to a ventilation valve via a common air line and at least the cavities of one of the groups of boxes can be connected to a pressure source, preferably via the assigned ventilation valve.

In contrast, is an insulating layer to avoid radiation losses z. B. during the night hours between the web 10 and the liquid, it is sufficient to open the valve 14 ', whereby the boxes 60 empty themselves and air flows into them. If, in addition, the load-bearing capacity of the cover elements is to be increased, the valve 14 'can then be closed again, as a result of which the boxes 60 also act as buoyancy bodies.
