Abstract
A device (10) for controlling a flow of liquid, comprising a well (11) having an inlet tube (12) and an outlet opening (13), wherein the inlet tube (12) is arranged with an inlet opening (14) and a longitudinal axis (A), wherein the device further comprises a closing device (19) for at least partially closing the inlet opening (14), and a movable floating body (20), wherein the inlet tube (12) or the closing device (19) is operatively connected to the floating body (20) to control the closing of the inlet opening (14) by means of the closing device (19). The inlet opening (14) is arranged in an angle (a) to the outlet opening (13) of the well (11) to prevent a substantial part of the liquid from passing directly from the inlet opening (14) to the outlet opening (13) of the well (11). The invention also relates to a method for controlling a flow of liquid.
