Apparatus for the contamination-free drainage of clean water in an aircraft

Abstract

An apparatus for the contamination-free drainage of fresh water in an aircraft, the apparatus having a fresh water supply line ( 8 ) with a fresh water outlet ( 2 ) from which water issues during drainage, and disposed downstream thereof an inlet opening ( 4 ) of a line ( 9 ), the inlet opening being provided for receiving drainage water and the line ( 9 ) being connected to the waste water system of the aircraft, and the fresh water outlet ( 2 ) and the inlet opening ( 4 ) being disposed in a housing ( 1 ) which has an overflow ( 7 ).

1 . An apparatus for the contamination-free drainage of fresh water in an aircraft, the apparatus having a fresh water supply line with a fresh water outlet from which water issues during drainage, and disposed downstream thereof an inlet opening of a line, the inlet opening being provided for receiving drainage water and the line being connected to the waste water system of the aircraft, wherein the fresh water outlet and the inlet opening are disposed in a housing which has an overflow. 
     
     
         2 . An apparatus according to  claim 1 , wherein the inlet opening is in the form of a funnel. 
     
     
         3 . An apparatus according to  claim 1 , wherein the fresh water outlet is disposed at the lid of the housing or is part of the lid. 
     
     
         4 . An apparatus according to  claim 1 , wherein the inlet opening is disposed at the base of the housing or is part of the base. 
     
     
         5 . An apparatus according to  claim 1 , wherein the central axes of the inlet opening and of the fresh water outlet are concentric. 
     
     
         6 . An apparatus according to  claim 1 , wherein the central diameter D E  of the inlet opening at the end towards the fresh water outlet is at least half the size of and more preferably greater than 75% of the size of the outside diameter D G  of the housing. 
     
     
         7 . An apparatus according to  claim 1 , wherein the overflow is disposed at the base of the housing or is part of the base. 
     
     
         8 . An apparatus according to  claim 1 , wherein at least one ventilation bore is provided in the housing. 
     
     
         9 . An apparatus according to  claim 1 , wherein the fresh water supply line has a valve ( 16 ) which must be opened for draining. 
     
     
         10 . An apparatus according to  claim 9 , wherein the overflow line attached to the overflow is equipped with a water-detecting device which is so configured that it automatically sends a signal to the valve in the event of water overflowing, whereby the drainage of fresh water is reduced or completely stopped. 
     
     
         11 . An apparatus according to  claim 9 , wherein a water level measuring device is disposed at the inlet opening, which sends a signal to the valve in dependence on the water level in the inlet opening, whereby the rate of flow of the fresh water is reduced. 
     
     
         12 . An apparatus according to  claim 1 , wherein an overflow opening, through which the water is able to flow into the overflow, is disposed beneath the inlet opening.
