Definitions

  • the invention relates to a capless filler neck with delayed-closing flap for a neck of a container, in particular a tank of a motor vehicle with a long piece of a nozzle axis extending piece of pipe and a closure mechanism having an upper flap and an underlying lower flap, wherein at least the lower flap as sealing flap is formed and the upper closure flap and the lower closure flap by the insertion of a filling tube into the tube piece against a restoring force for opening the closure mechanism are alstagbar.
  • Lidless filler neck with delayed closing flap of this kind are from the WHERE WO 2009/135954 A GERDES GMBH 20091112 known. These are filler necks that securely close the filler neck of a fuel tank with the two closing flaps, even without a separate tank lid. Here, the two flaps are pushed through the pipe end of a fuel nozzle or a Nach Schollkanisters, hereinafter referred to as general with filling tube, usually with safety mechanisms are present, such as prevent unintentional opening. Only when both flaps are open, the tank can be filled.
  • the disadvantage of the known filler neck can consist in that the user already or only tries to fill up with fuel even when only partially inserted filling pipe or after refueling at already partially pulled out filling pipe.
  • the lower flap is designed as a sealing flap, but then fuel above the already closed lower flap can be filled in the pipe socket, which then can no longer flow down into the tank. This means that the fuel can get through the vent systems in the environment, which is not desirable for environmental reasons.
  • the object of the invention is therefore to provide a Stutzenab gleich that ensures as long as possible even after actuation of the fuel nozzle after partial withdrawal from the nozzle end that the over-fueled fuel flows into the tank.
  • the upper flap is designed and stored so that it is not in direct or indirect contact with the lower flap and closed along a top pivot flap and along one, to the first pivoting subsequent second pivoting with a power transmission portion so on a pressure range of the lower flap at a distance to the pivot axis of the movable part of the lower flap supported that it is open without influence of the filling tube at least a few degrees, while the upper flap moves along the second pivoting path is.
  • a further solution to this problem is a spout closure having the features of claim 10.
  • the bottom closure flap is a pivoting flap which per se, with the exception of the delayed closure of the present invention, independent of the top closure flap of the filling nozzle of the dispensing nozzle is pushed open when it is introduced into the tank ..
  • the lower flap can remain open over a longer period. While in the known embodiment, the lower flap closes immediately after leaving the lower edge of the fuel nozzle from the pivoting range of the lower flap and thus seals, now the lower flap remains open longer. Although not the entire opening angle is available, however, the remaining opening angle is sufficient to allow the amount of fuel still filled in an approximately drawn-off fuel nozzle to drain safely downwards. This is because, according to experience, the full pump power of the fuel nozzle is only retrieved when it is completely located in the nozzle.
  • An essential feature of the invention is the fact that the upper closure flap or an auxiliary element between the upper closure flap and the lower closure flap as a result of the partially inserted filling tube causes the forced by the force of a spring in the closed position lower closure flap remains open for a certain time. This time is determined by the mechanical action of the lower portion of the filling pipe of the fuel nozzle, as long as it is between the two flaps.
  • the lower closing flap is pressed down mechanically via a lever actuated by the fuel nozzle.
  • the invention solves this problem now in that initially a first pivoting range is available, via which the upper closing flap can be pivoted through the inserted filling tube, or that the lower closing flap moves. Finally, at this first pivoting area, a second pivoting area is used, via which the further pivoting movement of the upper closing flap exerts an immediate pressure or an indirect pressure on the lower closing flap in the sense that the lower closing flap opens at least by a few degrees and thus becomes liquid-permeable.
  • indirect opening means that the upper closure flap exerts pressure on the lower closure flap via an additional actuator.
  • immediate opening should be understood in the context of the invention that the upper flap is urged with a section directly against the lower flap and thus applies the opening force, which is necessary to overcome the restoring force, even on the lower flap.
  • the upper closure flap thus has a force transmission section or presses a force transmission section of a separate actuating element downwards into the connection in the direction of the lower closure flap, the force transmission section then being displaceably supported on a pressure region of the lower closure flap.
  • the pressure range must be arranged at a distance from the pivot axis in the direction of the nozzle axis, so that an opening torque can be applied by the pressure of the power transmission section. It is irrelevant whether the flaps open in the same direction or each other, so are hinged to different sides of the pipe section. Also, the flaps do not have to be flat, on the contrary, they will usually have an inner flap space, in which, for example, over and vacuum valves are arranged.
  • the flaps may be shaped so that the opening of the lower flap is maintained over the largest possible pivoting range.
  • the upper closure flap is provided with a flap body which is substantially cylindrical and laterally protruding in the lower region has a flange on which, surrounding the flap body, the seal of the lower flap is arranged. This seal is then pressed upon closing the lower flap against a corresponding edge of the nozzle.
  • the pivot axis is arranged slightly above the flange.
  • the pivot axis of the opposite part of the flange forms the power transmission area. This means that the bottom of the flange upon opening of the upper flap around the pivot axis beyond the first pivoting out pushes against the pressure range of the lower flap and pushes further pivotal movement in the opening direction, the lower flap down and thus at least slightly opens.
  • the upper flap can be made flat on its upper side. However, it is also possible that it has an elevation on its upper side, so that even before the cross-sectional plane of the pipe section in which the pivot axis is located, contact between the filling pipe of the fuel nozzle under the upper shutter occurs. This has the effect that the top flap is depressed earlier and vice versa closes later. This in turn means that the opening or the closing of the lower closure flap occurs earlier or later as a result of the contact force occurring after the first pivoting path has been traveled.
  • the variation of its surface shape may cause the bottom flap to sooner or later come into contact with the downwardly pivoted top flap.
  • the pressure range of the lower flap can be designed accordingly. Essential for the chronological sequence of the opening of the two flaps is only the fact when the lines of movement of both flaps meet.
  • An alternative embodiment of the invention uses an additional component.
  • This component may for example be designed as a toggle lever and be provided within the pipe section between the upper closure flap and the lower closure flap as actuating means for the premature opening of the lower closure flap.
  • a toggle lever may for example be designed as a lever, which is articulated with one end to the pipe section.
  • the opposite, free end of the lever then projects in the direction of the nozzle axis and in the path of movement of the fuel nozzle, so that the inserted fuel nozzle pushes the lever down.
  • this pushes with its free end then on the pressure surface of the lower flap and pushes them, as already described above in connection with the upper flap on.
  • the geometry of the lever and lower flap can optimize the opening times.
  • a hollow-cylindrical element can also be slidably provided between the two closing flaps so that, after a certain opening angle of the upper closing flap, it is pressed down by either the filling nozzle or the upper closing flap and the lower closing flap opens slightly.
  • Figure 1 is a sectional view of a nozzle closure according to the invention.
  • FIG. 1 schematically an alternative embodiment of the invention.
  • the nozzle end has in the upper region of its pipe section 1 a threading funnel for insertion of the filling tube 4 of a fuel nozzle.
  • This upper closure flap 2 is pivotally mounted about a pivot axis S and can be pushed open by the introduced fuel nozzle.
  • the upper closure flap 2 has a flange carrying a seal.
  • the flange of the flap 2 moves with its the pivot axis S remote from the edge along a circular path.
  • This line of movement initially runs in a circle from a lateral position, starting from top to bottom, about the pivot axis S. After a first angle section of the line of movement, a first pivoting path is run through, during which the top closing flap 2 does not yet come into contact with the bottom closing flap 3. This ensures that both flaps 2, 3 operate independently of each other and both can respectively seal the stub.
  • the upper flap 2 Only after passing through the first pivoting path, the upper flap 2 abuts the top of the lower flap 3. Since the further line of movement of the right in the drawing edge of the flange, ie that edge which is opposite to the pivot axis S, the plane of the top of the lower flap. 3 is also slightly opened by further opening the upper flap 2 in the lower flap 3, without the filling tube 4 of the fuel nozzle would have to come into contact with the lower flap 3.
  • the lower closure flap 3 also closes only when the upper closure flap 2 has moved back into the region of the first pivoting path, which happens only when the filling tube 4 of the dispensing nozzle is pulled out of the tube piece 1 comparatively far.
  • closure now occurs again much later, so that fuel still running out of the fuel nozzle through the lower flap 3 can run into the tank. This avoids that a larger amount of fuel between the two flaps 2,3 accumulates or passes through the vent of the tank system in the environment.
  • the upper closure flap 2 which can open up our closure flap 3
  • the upper closure flap 2 has a force transmission region 5 in the described region of the flange, which upon reaching the second pivoting travel is supported on a pressure region 6 of the lower closure flap.
  • the pressure region may in principle be formed by any part of the lower closure flap 3 which may come into contact with the force transmission section 5.
  • FIG. 1 Here is the pivoting range of the upper flap except the power transmission section 5 outside the lower flap 3.
  • the power transmission section 5 presses not on the lower flap 3 itself, but on the outside of the sealing region arranged pressure region 6, which is designed here as radially outwardly beyond the pivot axis S in the direction opposite to the lower flap 3 direction out extension of the lower flap 2 is formed.
  • the lower flap 3 must indeed be within reach of the filling tube, but should be located as deep as possible within this range, so that it is as well protected as a sealing flap against accidental influences acting on the body.
  • the force transmission section which extends the upper closure flap radially on the side facing away from the pivot axis and by the optional pressure range, which additionally or alternatively displaces upward the pressure surface for easy regurgitation, the lower closure flap 3 can now be optimally placed and yet as of the pivoting movement the upper flap 2 to be formed independently openable flap. This means that even if the upper flap is damaged or completely missing, the pipe socket sealed on the one hand, but remains accessible for emptying, for example.
  • FIG. 2 shows a variant of the invention.
  • the lower closure flap 3 is not stopped by the upper closure flap 2 but an auxiliary component in the form of an opening lever 7.
  • opening lever 7 are located a receiving groove 8, in which the lever can be displaced by the filling tube 4 and in which the pivot bearing is located.
  • a receiving groove 8 can also be dispensed with.
  • the opening lever 7 is bent here to be able to stop the lower flap 3. Instead of the curvature shown, it can also be angled, in particular formed at right angles.
  • the lower closure flap 3 remains open for a certain time by the configuration according to the invention, so that fuel still flowing out of the filling tube 4 can flow through this opening into the tank, as shown diagrammatically in FIG. 2 by the arrow.
