Storage space as in claim 1, characterized by at least one curved surface (30 or 31) in the runoff area of the storage space and channeling the flushing torrent into a runoff gutter.

Claim 15

Storage space as in claim 13, characterized by curved surfaces (30 and 31) opposite each other and mutually displaced in a runoff area.

Claim 16

A storage space for liquids, comprising: a rain basin; at least one flushing chamber positioned at a maximum height of the bottom of said storage space and fillable with storage liquid; said flushing chamber emitting storage liquid in form of a torrent of flushing water through at least one flushing opening when said storage space empties; said flushing chamber filling automatically with storage liquid as the level of storage liquid rises; means for retaining storage liquid in said flushing chamber once said storage liquid has arrived in said flushing chamber; closure means controlled by the level of storage liquid in said storage space for closing and opening said flushing opening; said flushing chamber collecting a part of said liquid; said part of liquid being first released through said flushing opening when said storage space has emptied to enable flushing said storage space thoroughly with a strong torrent from the maximum height to the minimum height of the bottom of said storage space to remove sludge deposited in said storage space; means for closing off said flushing opening; float means in said storage space for actuating said means for closing off said flushing opening; a runoff area in said storage space, said float being in said runoff area and located dependent on the level of liquid in said storage space and liquid in said runoff area.

Claim 17

A storage space for liquids, comprising: a rain basin; at least one flushing chamber positioned at a maximum height of the bottom of said storage space and fillable with storage liquid; said flushing chamber emitting storage liquid in form of a torrent of flushing water through at least one flushing opening when said storage space empties; said flushing chamber filling automatically with storage liquid as the level of storage liquid rises; means for retaining storage liquid in said flushing chamber once said storage liquid has arrived in said flushing chamber; closure means controlled by the level of storage liquid in said storage space for closing and opening said flushing opening; said flushing chamber collecting a part of said liquid; said part of liquid being first released through said flushing opening when said storage space has emptied to enable flushing said storage space thoroughly with a strong torrent from the maximum height to the minimum height of the bottom of said storage space to remove sludge deposited in said storage space; means for closing off said flushing opening; float means in said storage space for actuating said means for closing off said flushing opening; a runoff area in said storage space, said float being in said runoff area and located dependent on the level of liquid in said storage space and liquid in said runoff area.
