Air duct system for a rail vehicle of passenger traffic

Abstract

An air duct system for a passenger rail vehicle has a first component venting duct with at least one opening to a second component venting duct and at least one air outlet for ventilating an inner space of the rail vehicle. Furthermore, a membrane that can be held in a formable and/or movable manner is arranged on the air duct system in such a manner that the membrane reduces and or closes the opening and opens the air outlet in a first state and reduces or closes the air outlet and opens the opening in a second state.

         11 . An air duct system for a rail vehicle of passenger traffic, the air duct system comprising:
 a first part-ventilation duct;   a second part-ventilation duct;   a diaphragm retained in a deformable and/or movable manner;   said first part-ventilation duct having at least one opening formed therein to said second part-ventilation duct and at least one air outlet for ventilating an inner space of the rail vehicle; and   said diaphragm being retained so as to be able to be deformed and/or moved and disposed such that said diaphragm reduces or closes said opening in a first state and releases said air outlet and, in a second state, said diaphragm reduces or closes said air outlet and releases said opening.   
     
     
         12 . The air duct system according to  claim 11 , wherein:
 said opening in said first part-ventilation duct is one of a plurality of openings disposed over a length of said first part-ventilation duct; and   said air outlet in said first part-ventilation duct is one of a plurality of air outlets disposed over said length of said first part-ventilation duct.   
     
     
         13 . The air duct system according to  claim 11 , wherein said diaphragm for reducing said opening has a hole formed therein which has a smaller clear width than said opening. 
     
     
         14 . The air duct system according to  claim 11 , wherein said diaphragm contains an air-tight textile or a textile which is coated so as to be air-tight. 
     
     
         15 . The air duct system according to  claim 11 , wherein a movement and/or deformation of said diaphragm is brought about in a manner free from foreign energy, simply by changing an air pressure at said diaphragm in the air duct system. 
     
     
         16 . The air duct system according to  claim 12 , wherein:
 at least two of said air outlets are spaced apart from each other in a longitudinal direction of said first part-ventilation duct;   said diaphragm extends parallel to a longitudinal axis of said first part-ventilation duct at least between said two air outlets and delimits said first part-ventilation duct; and   said diaphragm and said air outlets are adapted to each other such that, in the first state of said diaphragm, for a predetermined total air flow, air flows from both of said air outlets are substantially of a same size.   
     
     
         17 . The air duct system according to  claim 12 , wherein:
 at least two of said openings are spaced apart from each other in a longitudinal direction of said first part-ventilation duct;   said diaphragm extends at least between said two openings parallel to a longitudinal axis of said first part-ventilation duct and delimits said first part-ventilation duct; and   said diaphragm and said openings are adapted to each other in such a manner that, in the second state of said diaphragm, for a predetermined total air flow, the air flows from both of said openings are substantially of a same size.   
     
     
         18 . The air duct system according to  claim 11 , wherein said diaphragm is disposed in the air duct system in such a manner that said diaphragm delimits a cross-section of said first part-ventilation duct for guiding an air flow and in that said diaphragm is retained so as to be able to be deformed and/or moved in such a manner that the cross-section in the second state is smaller than in the first state. 
     
     
         19 . The air duct system according to  claim 11 , wherein said first part-ventilation duct is disposed as a roof air duct in a ceiling of the rail vehicle, and in that said second part-ventilation duct is disposed in side walls of the rail vehicle. 
     
     
         20 . The air duct system according to  claim 11 , wherein said opening in said first part-ventilation duct is one of a plurality of openings disposed over a length of said first part-ventilation duct. 
     
     
         21 . The air duct system according to  claim 11 , wherein said air outlet in said first part-ventilation duct is one of a plurality of air outlets disposed over said length of said first part-ventilation duct. 
     
     
         22 . The air duct system according to  claim 11 , wherein said diaphragm for reducing said air outlet has a hole formed therein which has a smaller clear width than said air outlet. 
     
     
         23 . A rail vehicle for passenger transport, comprising:
 an inner space; and   an air duct system, containing:
 a first part-ventilation duct; 
 a second part-ventilation duct; 
 a diaphragm retained in a deformable and/or movable manner; 
 said first part-ventilation duct having at least one opening formed therein to said second part-ventilation duct and at least one air outlet for ventilating said inner space of the rail vehicle; and 
 said diaphragm being retained so as to be able to be deformed and/or moved and disposed such that said diaphragm reduces or closes said opening in a first state and releases said air outlet and, in a second state, said diaphragm reduces or closes said air outlet and releases said opening.
