Problems solved by technology

[0004] The disadvantage of solenoid-operated valves is that at least one electrical emergency current source must always be present even in emergency situations in which the valve must be operated
For this purpose, an auxiliary turbine (RAM-Air-Turbine Ram Air Turbine) is provided in the passenger aircraft, which ensures emergency power supply even in the event of a shutdown of all engines, but only in a limited amount

Embodiment Construction

[0023] according to figure 1 and figure 2 The oxygen emergency supply shown is arranged in a known manner in an aircraft not shown in detail in the figures, as in the cited prior art.

[0024] The illustrated oxygen emergency supply has a high-pressure oxygen cylinder 1 in which oxygen is stored at a pressure of, for example, 200 Bar. A pressure reducing valve 2 is provided at the outlet of the high-pressure oxygen cylinder 1. The pressure reducing valve 2 reduces the pressure to 2 Bar and provides it to the pipeline network through the supply pipeline 3. The pipeline network has four leading to the pulse breathing mask 4 here. The pipelines 5 are connected with the supply pipeline 3 pipelines. Parallel to the supply line 3 , after the pressure reducing valve 2 in the direction of flow, an auxiliary line 6 is connected, which is branched in a manner analogous to the branching of the supply line 3 into four openings into the line 5 . Pipeline 7.

Abstract

The invention relates to an oxygen emergency supply device for passengers in an aircraft. The oxygen emergency supply device for passengers in the aircraft comprises an oxygen source, the oxygen source is provided with a plurality of pulsed breathing masks which are connected to the oxygen source by pipelines, a single stop valve is arranged in each pipeline to the corresponding breathing mask, and each single stop valve is switched to a shut-off state in an inoperative state. Furthermore, the oxygen emergency supply device is provided with a pulse-type breathing control device for operating each single stop valve and auxiliary pipelines, the auxiliary pipelines connect the oxygen source with the breathing masks under the condition of bypassing the single stop valves, and each auxiliary pipeline is connected with the corresponding pipeline to the corresponding breathing mask or the corresponding breathing mask via the corresponding stop valve. The auxiliary pipelines are connected to the oxygen source via a central stop valve which is switched to an open state in an inoperative state.

Description

technical field [0001] The invention relates to an emergency oxygen supply device for passengers in an aircraft and an aircraft with such an emergency oxygen supply device for passengers. Background technique [0002] In the prior art, there are oxygen emergency supply devices for passengers on the aircraft. These oxygen emergency supply devices are used to ensure that a sufficient amount of oxygen can be supplied to the passengers in the event of a sudden pressure drop at a large altitude until the aircraft descends to a flight altitude sufficient to supply oxygen to the passengers from the environment. For this purpose, containers with breathing masks are usually arranged above the row of seats, these containers are opened in the event of a sudden drop in pressure, so that the breathing masks fall downwards towards the passenger and the passenger is supplied with the aid of an oxygen generator or from a high-pressure oxygen cylinder. Provide needed oxygen. For this, ther...
