A railway vehicle having pneumatic actuated devices connected to a pneumatic system including a refillable supply tank connected to the control and actuation elements of the pneumatic devices is provided with a device for coupling the supply tank to a source of pressure medium as the vehicle approaches the source. The apparatus comprises a supply funnel on the vehicle connected to the supply tank and a supply nozzle connected to a source of pressure medium at a station. The supply nozzle is provided with receiver means. On the vehicle there is provided contact means which are engageable with the receiver means as the vehicle enters the station to align coaxially the funnel and nozzle and to impart relative longitudinal movement between the funnel and nozzle to couple these elements in tight coupled position. The funnel and nozzle are each provided with check valves which are opened simultaneously upon coupling of the funnel and nozzle.
In a vehicle, particularly a railway vehicle, having pneumatic actuated devices connected to a pneumatic system including a refillable supply tank connected to the pneumatic devices, an apparatus for coupling and uncoupling the vehicle supply tank to a source of pressure medium while the vehicle approaches the source in a direction of travel and comprising a supply funnel connected to the vehicle supply tank, a supply nozzle connected to a source of pressure medium at a station and moveable in said direction of travel, receiver means at said supply nozzle, and contact means on said vehicle engageable with said receiver means as the vehicle enters the station and approaches the source of pressure medium for aligning coaxially said funnel and nozzle during movement of the vehicle and for imparting relative longitudinal movement between said funnel and nozzle after the funnel and nozzle are aligned to couple said funnel and nozzle.
