    摘要： A valve assembly is dimensioned for interconnection between a pressurized gas supply system and a pressurized gas braking system of a rail vehicle. The valve assembly can include a valve housing and a valve body. The valve housing can include a housing wall that at least partially defines a housing chamber and includes a plurality of communication ports in fluid communication with the housing chamber. The valve body is supported within the housing chamber for sliding movement relative to the housing wall. The valve body can be displaced between a plurality of positions in which different ones of the communication ports are in fluid communication with one another. A pressurized gas system and a rail vehicle are also included.
