  • the nozzle comprises a housing 1 with an inlet 2 to which a supply line for supplying a fluid is connected. (not shown).
  • a discharge pipe 3 is inserted, at the front end of which an outlet 25 is located.
  • the outlet 25 can, for example, be inserted into a filler neck 22, 26 of a vehicle (see Figures 5 and 7 ).
  • a main channel 16 extends from the inlet 2 to the outlet 25, in which a main valve 5 is arranged to control the total volume flow.
  • the main valve 5 comprises a main valve body 6 (see Figure 2 ), which can be moved against a main valve seat 27 to close the main valve 5.

  • the restoring force of the restoring element 13 is so small that the valve body 6 together with the inner piston 12 can be moved into the open position by a normal fluid pressure.
  • the automatic shut-off device 30 is designed to move the main valve 5 into a closed position regardless of the position of the switching lever 4.
  • the functioning of the automatic shut-off device is basically known (see for example EP 2 386 520 A1 ) and will not be explained in more detail here.
  • the nozzle is designed to optionally deliver a first maximum volume flow or a second maximum volume flow.
  • the nozzle comprises a throttle valve arranged in the outlet pipe, which is designed to optionally limit the fluid flow to the first or second maximum volume flow.
  • the throttle valve is actuated by interaction with a ring magnet of a filler neck according to ISO 22241-4. By default, i.e. if there is no ring magnet, the nozzle is set to deliver the first maximum volume flow. If the outlet pipe 3 is inserted into a filler neck without a ring magnet, the first maximum volume flow can be delivered by operating the switch lever 4.
  • the first maximum volume flow is 9 l/min in this case.
  • the nozzle can deliver the second maximum volume flow, which is 20 l/min in this case.
  • the functionality of the throttle valve is explained in conjunction with the Figures 9 to 11 explained in more detail.
  • the functioning of the automatic shutdown device 30 requires that it be subjected to a vacuum.
  • the vacuum is generated as described below.
  • the main channel 16 merges downstream of the main valve 5 in the area 14 into a sub-channel 10 and into five parallel bridging channels 20a to 20e (see Figure 3 ).
  • the partial channel 10 is delimited by a wall 31.
  • the partial channel 10 has an opening 32 defined by the wall 31 and a section 33 tapering conically from the opening 32 in the direction of flow (see Figure 2 ). In the area of section 33 there is an inlet 8 of a vacuum line 9 into the partial channel 10. Due to the tapering section 33, the flow speed of the fluid in the partial channel 10 increases, so that the static pressure drops.
  • the bridging channels 20a to 20e each have a means for prioritizing the fluid flow, which in the present case is designed as an overflow valve 21a to 21e, whereby the overflow valves 21d and 21e are not visible in the sectional view shown.
  • the Figure 2 The overflow valve 21c shown in FIG. 1 is described. It comprises a shaft 19 and a closing body 17, which is tensioned upstream into a closed position by a return element 18. In the Figures 1 to 3 the main valve 5 is closed so that no fluid flows through the main channel 16. The closing body 17 of the overflow valve 21c is held in the closed position by the return element 18. The other overflow valves are also in the Figures 1 to 3 accordingly in their closed position.
  • the return elements 18 of the overflow valves 21a to 21e have different return forces, so that different fluid pressures are required to open the overflow valves 21a to 21e. This will be explained below in connection with the Figures 5 to 8 explained in more detail.
  • valve stem 15 By operating the control lever 4, the valve stem 15 is moved downstream so that the outer sleeve 24 of the valve stem 15 is released from the valve body 6 (see Figure 4 ). If no fluid is supplied to the inlet 2, the valve body 6 initially remains in the closed position, as already explained above, in which it is pressed against the valve seat 27 by the return element 13. This is in the Figure 4 illustrated.
  • the valve body 6 Only when a fluid with a certain fluid pressure is supplied to the inlet 2, the valve body 6 gives way to the opening pressure and moves against the force of the return element 13 into an opening position. This is shown in the Figures 5 and 6 shown.
  • the fluid can now enter from the inlet 2 into the area 14 in front of the partial channel 10 and the bridging channels 20a - 20e. Part of the fluid flows into the partial channel 10 and another part of the fluid in the direction of the overflow valves 21a to 21e. Since the overflow valves 21a to 21e are initially forced into the closed position by the return elements 18, a larger proportion of the fluid initially flows through the partial channel 10, so that a flow occurs there shortly after the main valve 5 opens and a vacuum is generated.
  • a fluid pressure builds up on the upstream-facing front surfaces of the closing bodies 17 of the overflow valves 21a to 21e, which depends on the supply pressure of the fluid, the opening position of the main valve and the available flow cross-sections within the nozzle downstream of the overflow valves 21a to 21e.
  • the nozzle according to the invention is shown after the outlet pipe has been inserted into a filler neck 22 of a vehicle and the main valve has been opened.
  • the filler neck 22 is designed in accordance with ISO 22241-5 and does not have a ring magnet. Accordingly, the throttle valve located in the outlet pipe 3 is in the closed position and allows a maximum flow through the outlet pipe 3 of approximately 9 l/min.
  • the restoring forces of the overflow valves are set in particular so that the resulting fluid flow through the partial channel 10 assumes an optimal value for vacuum generation.
  • the overflow valves 21d and 21e which cannot be seen in this view, also have a greater restoring force than the overflow valve 21b and therefore remain closed.
  • FIGS. 7 and 8 show the nozzle according to the invention after it has been inserted into a filler neck 26 according to ISO 22241-4 with ring magnet 23.
  • the ring magnet 23 actuates the throttle valve in a manner explained in more detail below, so that the nozzle can now deliver a maximum volume flow of 20 l/min. Due to the increased maximum volume flow, there is a higher fluid pressure in the area 14 in front of the partial channel 10 and the bridging channels 20a-20e, so that all overflow valves 21a-21e open (see Figure 8). By opening all overflow valves, the volume flow flowing through the partial channel 10 can be increased compared to the volume flow in the
  • Figures 5 and 6 shown state can be kept almost the same.
  • the vacuum generated by the partial channel 10 is thus essentially constant, regardless of whether the first maximum volume flow of approximately 9 l/min or the second maximum volume flow of approximately 20 l/min is delivered with the dispensing valve. Even with other volume flows, which can be set in particular with the aid of the hand lever and an opening position of the main valve corresponding to the hand lever position, the overflow valves according to the invention lead to an equalization of the vacuum generated.
