Abstract
A circulation device for circulating a liquid in a treatment vessel, in particular in a treatment vessel for treating light-sensitive material. The circulation device has a feed pipe arranged roughly vertically in the treatment vessel, through which liquid from a feed line can flow into the treatment vessel. The flow cross-section (A) of the feed pipe is dimensioned so that the liquid flowing in from the feed line backs up in the feed pipe and produces a hydrostatic pressure that is such that the liquid flowing from the outlet opening of the feed pipe produces a circulation movement of the liquid in the treatment vessel.

A circulation device for circulating a liquid in a treatment vessel for treating light-sensitive material, wherein the circulation device has a feed pipe arranged roughly vertically in the treatment vessel through which liquid can flow in from a feed line into the treatment vessel, a flow cross-section (A) of the feed pipe being dimensioned so that the inflowing liquid from the feed line backs up in the feed pipe and generates a hydrostatic pressure which is such that outflowing liquid from an outlet opening of the feed pipe produces a circulation movement of the liquid in the treatment vessel.
