Device and method for active pressure regulation in rail vehicles

Abstract

A device for active regulation of the internal vehicle pressure in a rail vehicle includes an aeration device for increasing the internal pressure in the rail vehicle, a ventilation device for reducing the internal pressure in the rail vehicle, and a measuring device for measuring the internal pressure in the rail vehicle. A control device is connected for signaling purposes at least to the ventilation device in order to reduce the internal pressure and to the measuring device, and the ventilation device for reducing the internal pressure can be controlled by the control device according to the internal pressure determined by the measuring device.

1 - 10 . (canceled) 
     
     
         11 . A device for active regulation of an internal vehicle pressure in a rail vehicle, the device comprising:
 an aeration device configured to increase the internal pressure in the rail vehicle;   a ventilation device configured to reduce the internal pressure in the rail vehicle;   a measuring device configured to measure the internal pressure in the rail vehicle; and   a control device connected for signaling at least to said ventilation device and to said measuring device, said control device configured to control said ventilation device in dependence on the internal pressure determined by said measuring device.   
     
     
         12 . The device according to  claim 11 , wherein said control device has an input channel for introducing a diagnostic signal indicating at least one of an open or closed state of at least one of an external door or a window of the rail vehicle. 
     
     
         13 . The device according to  claim 11 , wherein said measuring device is configured to determine the internal pressure in the rail vehicle at least at one of a train level or a car level. 
     
     
         14 . The device according to  claim 11 , wherein said ventilation device includes at least one of an external valve, a ventilation flap or a fan. 
     
     
         15 . A method for active pressure regulation of an internal pressure in a rail vehicle, the method comprising the following steps:
 increasing the internal pressure within the rail vehicle by using an aeration device;   measuring the internal pressure within at least one sub-area of the rail vehicle by using a measuring device;   adjusting the internal pressure within the rail vehicle by using a ventilation device; and   controlling the ventilation device with a control device in dependence on the internal pressure determined by the measuring device as required if a specified internal pressure has built up within the rail vehicle.   
     
     
         16 . The method according to  claim 15 , which further comprises controlling the ventilation device within a climate control of the rail vehicle. 
     
     
         17 . The method according to  claim 15 , which further comprises:
 provided the ventilation device with at least one of an external valve, a ventilation flap or a fan; and   carrying out a regulation of the internal pressure by opening or closing at least one of the external valve or the aeration flap or regulating a speed of the fan.   
     
     
         18 . The method according to  claim 15 , which further comprises carrying out the step of measuring the internal pressure only with external doors and windows of the rail vehicle closed. 
     
     
         19 . The method according to  claim 15 , which further comprises carrying out the step of measuring the internal pressure within the rail vehicle while carrying out at least one of passenger operations or an inspection of the rail vehicle. 
     
     
         20 . The method according to  claim 15 , which further comprises carrying out the step of measuring the internal pressure at least at one of a train level or a car level.
