Embodiment Construction
[0025] figure 1 A schematic partial sectional view of a fuel nozzle 1 with a nozzle housing 2 is shown, which has a fuel distribution pipe 4 on the one hand and a pump hose connection 6 on the other. The manual lever 8 shown in the filling position is used to actuate the dispensing valve 10 in a known manner.
[0026] According to the invention, a device 12 for extracting fuel vapors is arranged in the fuel nozzle 1 and during the refueling process the fuel vapors are extracted via a fuel extraction pipe 14 which is arranged coaxially with the fuel distribution pipe 4 And it is connected to the device 12 via a gas flow path not shown in detail.
[0027] figure 2 is a longitudinal sectional view illustrating the structure of the device 12 for extracting fuel vapor in the closed position. This device 12 has a gas valve 16, which is connected to a vacuum source via a gas hose (not shown), and which is arranged in the region of the fuel inlet location into the fuel gun housing...
