An overflow main portion has a vent valve (15) having a deflection channel connected to the control channel which is above the deflection channel and having its longitudinal axis extending transversely to the overflow main portion opening into the end of riser. The control channel opens in the deflection channel via a control opening such that the return line is formed in the non-overlapping wall portion of deflection channel. |
