Problems solved by technology

If the pressure load is provided by bleed air, this pressure source is no longer available, for example, when the vehicle is on the ground with the engines turned off
If a compressor is used, it increases the weight of the system due to redundancy

Embodiment Construction

[0038] figure 1 A schematic configuration of a pressure supply system connected to a fresh water supply system is shown. exist figure 1 In the arrangement shown in , the operation and configuration of the pressure supply system is illustrated by the aircraft's pressure supply system or the fresh water supply system. In this context, the dotted line 2 represents the boundary of the aircraft, the area outside the cabin of the aircraft lies above the boundary line and the cabin area of ​​the aircraft lies below the dotted line. Although according to the accompanying drawings, the pipeline comprising the negative pressure valve 15, the overpressure valve 17 and / or the air pump 40 is discharged to the outside of the cabin or the aircraft, the pipeline comprising the negative pressure valve 15, the overpressure valve 17 and / or the air pump 40 The lines can also be vented into the cabin or aircraft interior.

[0039] Herein, the pressure supply system 1 includes a water storage 10...

Abstract

A pressure supply system (1) for a fresh water system of an aircraft, comprising a water reservoir (10) having a bleed air inlet (11) and a water outlet (12), and comprising a water pump (30) so as to load water, which is loaded with bleed air pressure, with a further pressure downstream until a predetermined nominal operating pressure range is achieved, it being possible as a result to provide an increased redundancy by pressure generator assemblies which are based on different pressure generation principles.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from the filing dates of German Patent Application No. 102011109943.7, filed August 10, 2011, and U.S. Provisional Patent Application No. 61 / 522,048, filed August 10, 2011, the entire disclosure of which is incorporated by reference Incorporated into this article by way of citation. technical field [0003] The present invention relates to a pressure supply system for a water system, in particular to a pressure supply system for a fresh water system in an aircraft, and to an aircraft comprising a corresponding pressure supply system for a fresh water system. Background technique [0004] In order to ensure that the water in the water system leaves at a corresponding tap point, eg a tap, or at a sufficiently high pressure, it is necessary to load the water in the fresh water system with a pressure which causes the water to be delivered to the point of withdrawal. In aircraft, a correspo...
