Abstract (en)
[origin: WO2019068598A1] A flow device (110) for controlling and/or adjusting a counter pressure (115) in a pneumatic sand-conveying device (105) for a rail vehicle has at least one conveying channel device (200) and a controllable counter pressure device (205). The conveying channel device (200) is formed to convey sand (210). The controllable counter pressure device (205) is coupled to the conveying channel device (200), and arranged and/or formed to generate the counter pressure (115) against and/or perpendicular to a conveying direction (215) of the sand (210) conveyed in the conveying channel device (200), or against and/or perpendicular to an intended conveying direction (215) of the sand (210) that can be conveyed in the conveying channel device (200).
