Abstract

A fluid-disposing system for a galley sink includes: a galley sink for a galley cabin monument, a self-regulating valve, a control unit, a sensor, and a signal connection between the sensor and the control unit. The valve input is connected to a fluid line, connected to a drainage opening of the galley sink. The valve is arranged underneath the drainage opening, such that fluid from the galley sink can flow through the associated drainage opening into the fluid line. The valve output is designed to be couplable with a source of negative pressure. The valve is designed to automatically open at a predetermined amount M1 of fluid in the fluid line, such that fluid can flow out of the fluid line, and to automatically close at a predetermined amount M2 of fluid in the fluid line, such that the predetermined amount M2 of fluid remains in the fluid line.
