DEVICE FOR CONTROLLING A CONSTANT OUTFLOW FROM A TANK

摘要

The invention relates to a device (1) for controlling a constant outflow fro m a tank, especially a rain retention chamber. The device has an outlet opening (6) for the liquid, whereby a shutter (10) that moves in a straight line is assigned to the outlet opening, which controls the outlet of the liquid from the container depending on the liquid level. A component (40 ) that can change its position depending on the liquid pressure or the liquid backup in the liquid controls the shutter by way of a curve (23). The shutter movement of the shutter occurs opposite a resetting force. According to the invention, it is provided that a control element (22) that can rotate around an axis (21) has a curve (23), whereby the curve is used to convert the movemen t of the control element into the translational movement of the shutter.
