    摘要： An apparatus for developing photographic material having a delivery device and a removal device for developing fluid as well as an inlet and an outlet for the material to be developed with a narrow conduit that extends from the inlet to the outlet. A transport mechanism for transporting the photographic material to be developed from the inlet through the conduit to the outlet wherein the material to be developed comes into contact with the developing fluid as it is transported through the conduit and is developed. Two half shells are connectable to one another, with each half shell having two plates joined to make the half shell. The apparatus also has a central positive displacement element, which together with the inner wall of the half shells, defines the conduit in which the photographic material is developed. The conduit extends between the positive displacement element and the respective inner wall of the half shell. The inner wall of the positive displacement element is embodied substantially as a flat face, while the outer wall reinforces the inner wall in order to prevent deformation of the inner wall by the high pressure of the developing fluid.
