  • the liquid valve 145 to be manually opened by depressing the tank filling device 101 against the filler neck 113 serves not only to supply liquid to a fuel tank 114, but also to aerate the liquid tank 105 to equalize the negative pressure built up by the outflowing fuel.
  • FIG. 11 shows the air duct 148 in particular centrally above the valve disk 141, wherein the air nozzle 147 - as Fig. 8 shows - are aligned radially to the longitudinal central axis 149 of the valve stem 146.
  • a plurality of, in particular three air nozzles 147 are provided over the circumference, which are in the embodiment in the circumferential direction with equal distances u to each other.
  • three air nozzles 147 are provided with a distance u of 120 °.
  • the air nozzles 147 connect together in the center of the valve disk 141 to the air channel 148 in the valve lifter 146.
  • the longitudinal center axis of an air nozzle 147 and the longitudinal center axis 149 of the valve stem 146 are preferably at a right angle to each other.
  • the air stub 147 are formed in ribs 188, the -. Fig. 8 extend in the region between the inner wall of the pouring spout 104 or its spout 106 and the valve stem 146.
  • the ribs 188 are advantageously formed integrally with the valve stem 146 and project through the annular space 150. The ribs 188 guide the valve stem 146 in the region of the liquid valve 145 within the spout 106, so that the end of the valve stem 146 in the open position - see. Fig. 8 - and in the closed position - cf. Fig. 9 - Is guided radially.
  • the ribs 188 are longer in the longitudinal direction of the valve plunger 146 than the opening stroke a1 + a2 of the valve 145; Preferably, the ribs 188 extend axially beyond the double to triple opening stroke a1 + a2.
  • Fig. 12 shows, are provided between the air channels 147 outflow regions 180 for the liquid, in the embodiment for the fuel; In a corresponding manner, inflow regions 190 are formed for the inflowing ambient air.
  • the outflowing fuel is indicated by arrows 181; the incoming ambient air is indicated by arrows 191.
  • the ribs 188 can be provided as a divider of the fuel flowing to the liquid valve 145, so that the fuel is discharged to the right and left into the outflow regions 180 above the air connection.
  • Fig. 12 clearly shows, alternate over the circumference of the valve disk 141 Abström Suitee 180 for the liquid and inflow regions 190 for the ambient air from each other, in particular evenly from each other.
  • Abström Suitee 180 for the liquid and inflow regions 190 for the ambient air from each other in particular evenly from each other.
  • successive outflow regions 180 for the outflow of the liquid, in the exemplary embodiment of fuel, and inflow regions 190 for the inflow of ambient air into the air channel 148 are formed on the valve disk 141 in the circumferential direction.
  • the measured angular range of a discharge region 180 is greater, advantageously several times greater than the angular region of an inflow region 190 measured in the circumferential direction.
  • an outflow region 190 extends over 100 ° and an inflow region exceeds 20 °.
  • the air nozzles 147 can - like Fig. 11 shows - be designed so that they lie with their air inlet forming end 171 'on a diameter which is smaller than the inner diameter I of the pouring spout 4.
  • Fig. 11 shows - be designed so that they lie with their air inlet forming end 171 'on a diameter which is smaller than the inner diameter I of the pouring spout 4.
  • the air nozzles are guided to the edge 157 of the valve disk; in plan view of the valve plate 141 according to Fig. 11 end the air nozzle 147 on the inner circumference of the pouring 4.
  • FIG. 13 is a section along the line XIII - XIII in Fig. 8 shown.
  • the valve stem 146 has on its outer circumferential surface guide ribs 188 ', which are guided in filling pieces 189 in the longitudinal direction of the valve stem 146.
  • the end of the valve tappet 146 carrying the valve disk 141 is guided radially in the region of the spout 106 of the pouring spout 104.
  • the valve tappet 146 In the open and in the closed position of the liquid valve 145, the valve tappet 146 is always centric; tilting during an opening movement or closing movement of the liquid valve 145 is thus avoided.
  • the patches 189 can - as from the view Fig. 13 can be seen - completely penetrate the annular space 150 between the valve stem 146 and the inner wall of the spout 106 and abut the outer surface of the valve stem 146.
  • the filler pieces 189 are expediently fixed in the spout 106 or in the pouring spout 104, so that the valve spool 146 moves relative to the filling pieces 189.
  • the filling pieces 189 are located above the air connection 147 (FIG. Fig. 11 ), whereby the filler 189 form a kind of roof for the air nozzle 147.
  • the fuel flow flowing through the annular space 150 to the liquid valve 145 is divided via the filling pieces 189 above the air connection 147, so that in the region of the open mouths the air connection 147 (FIG. Fig. 8 ) no fuel flows.
  • the fuel is discharged in the circumferential direction from the filler 189 to the right or left and exits through the outflow region 180.
  • the inflow regions 190 for the compensating air are thus substantially fuel-free, so that hardly or substantially no liquid or fuel flows in via the air stubs. This ensures that sufficient air can flow through the air connection 147 and the air channel 148 to equalize the pressure in the liquid container 105.
