Diesel rail vehicle with pressurized refueling, especially personal transport locomotive, has overfill safety valve with float unit that trips mechanism on reaching fill level to close filler opening

摘要

The vehicle has a pressurized refueling device with a dry coupling on the filler for connecting a refueling hose, a valve for ventilating and venting the tank and a limit sensor for shutting off a feed pump on reaching a defined level. The fuel tank has an overfill safety valve near the filler with a float unit that trips a mechanism on reaching the fill level to close the filler opening at normal fill pressure and prevent further filling. The vehicle has a device for pressurized refilling of the fuel tank (1) with a dry coupling (3) on the filler (2) for connecting a refueling hose, a valve (4) for ventilating and venting the tank and a limit sensor (5) for shutting off a feed pump in the fuel station on reaching a defined level. The fuel tank has an overfill safety valve (6) near the filler with a float unit (7) that trips a mechanism on reaching the fill level to close the filler opening at normal fill pressure and prevent further filling.
