Embodiment Construction

[0021] The device shown in the drawings is designed for combined pressure protection and air flow control in the interior of a rail vehicle, wherein as a preferred application the use in operative connection especially with the air inlet and air outlet of high-speed trains is mentioned . The functions of pressure protection and air flow are realized by common components, which control the free-flow cross-section of the air inlet and / or air outlet depending on the operating conditions.

[0022] figure 1 with image 3 As can be seen in , the device has a housing 2 which is designed to be pressure-tight and resistant to pressure shocks of a maximum magnitude of ±10 kPa. In an embodiment that is advantageous for mounting, the housing 2 is mounted on the base plate 1 .

[0023] A groove 3 is designed on the side of the housing 2 opposite to the bottom plate 1 . The groove is provided with a turn-over element 4 .

[0024] The folding element 4 is supported on the housing 2 via ...

Abstract

The invention relates to a device for combined pressure protection and airflow control in the interior of a high-speed rail vehicle, wherein the functions of pressure protection and airflow are realized by a common assembly that controls the air inlet and airflow according to specific operating conditions / or free flow cross-section of the air outlet. The object is to provide a device related thereto which requires a small installation space and a small number of separate components and which ensures fast and reliable control at high travel speeds. This object is achieved in that the device has a pressure-tight housing (2) resistant to pressure shocks of the magnitude ± 10 kPa at most, which housing is provided with a groove (3) on its side opposite to the bottom surface, the groove being equipped with The folding part (4), wherein the folding part (4) is supported on the housing (2) on the two end sections of the shaft (5) by a shaft (5) extending parallel to its longitudinal direction and arranged to be able to move along The shaft (5) rotates so that the groove (3) can be pressure-tightly closed starting from each position of the folding part (4), which is equipped with a drive assembly (7), which drives The assembly is operatively connected to the electric drive (8) for the positioning of the folding part (4) with precise repeatability in such a way that the closing process can be carried out within ≤ 50 ms from each position of the folding part (4) and wherein the electric drive (8) Connected to an adjustment element, which automatically adjusts the defined final position of the folding element (4) in a de-energized state.

Description

technical field [0001] The invention relates to a device for combined pressure protection and airflow control in the interior of a high-speed rail vehicle, wherein the functions of pressure protection and airflow control are implemented by a common assembly that controls the air inlet and / or air intake depending on the operating conditions or the free-flow cross-section of the air outlet. Background technique [0002] For high-speed trains, many aspects must be considered in order to avoid pressure surges and pressure fluctuations that inevitably occur during train operation. For structural components of rail vehicles, such as carriages, carriage passages, doors, windows, etc., a large number of technical solutions are already available, which can be adapted as optimally as possible to the respective conditions of use . In contrast, the number of suitable ventilation and air conditioning systems is significantly lower. [0003] A simple variant associated with this consis...
