outlet (15), a guide and/or support device (20) for the treatment element (13) is located in the first shaft element (11), the guide and/or support device (20) divides the first shaft element (11) into a treated side and an untreated side, the guide and/or support device (20) comprises a pipe fluid-tightly connected to the fluid inlet (14) of the first shaft element (11) on the untreated side, and has an opening (23) on the treated side, which forms a fluid connection with the fluid outlet (15) of the first shaft element (11), a throttle element (16) is located in the second shaft element (12) between a fluid inlet (17) and a fluid outlet (18), and the shaft elements (11, 12) are fluid-connected or fluid-connectable to one or several drainage-body elements (10). ### Claim 2 (depends on 1) The drainage-body unit according to claim 1, characterized in that the shaft elements (11, 12) and the drainage-body element (10), or several drainage-body elements (10), are integrated in a single, uniformly manageable component. ### Claim 3 (depends on 1, 2) The drainage-body unit according to claim 1 or 2, characterized in that the drainage-body element (10), or several drainage-body elements (10), are located between the shaft elements (11, 12). ### Claim 4 (depends on 1) The drainage-body unit according to claim 1, characterized in that the shaft elements (11, 12) and the drainage-body element (10), or several drainage-body elements (10), are located on a same level. ### Claim 5 (depends on 1) The drainage-body unit according to claim 1, characterized in that the fluid inlet (14) of the first shaft element (11), and the fluid outlet (18) of the second shaft element (12) are located on different levels. ### Claim 6 (depends on 1) The drainage-body unit according to
