Abstract (en)
[origin: WO2019068602A1] The invention relates to a flow device (105) for controlling and/or adjusting a pressure in a pneumatic sand-conveying device for a rail vehicle, which flow device has at least one pressure chamber (110) and a controllable pressure device (115). The pressure chamber (110) comprises a conveying nozzle interface (120) to a conveying nozzle device (125) for generating a pressure in the pressure chamber (110). The controllable pressure device (115) is coupled to the pressure chamber (110) and is designed to generate a pressure in order to control and/or adjust the pressure in the pressure chamber (110).
