Definitions
- the invention relates to a fuel tank made of thermoplastic material.
- fuel tanks can be produced in many different ways, for example by extrusion blow molding, thermoforming or injection molding.
- the vessel may have been obtained from a tubular extruded preform made of plasticized plastic.
- the preform is then expanded within a two-part tool under gas pressure, wherein the tool defines the outer contour of the finished molded container.
- fuel delivery units include a fuel pump with an electric motor and possibly a fuel filter, which are arranged together in a surge or Schlingertopf.
- the swirl pot ensures that the fuel pump in every driving situation, d. H. is sufficiently fueled during acceleration or cornering or strong inclination of the vehicle about the transverse or longitudinal axis.
- the swirl pot also already defines the reserve volume and is still provided with at least one level sensor.
- a fuel tank with a fuel delivery device arranged therein which has an opening through which hydraulic and / or electrical connection lines of the fuel delivery device are led to the outside.
- the fuel delivery device was introduced during the manufacturing process of the fuel tank in this and surrounded by the one-piece fuel tank. In other words, the fuel delivery unit was blown into it when the fuel tank was formed. Therefore, the fuel tank may have an opening whose diameter is substantially smaller than the dimension of the fuel delivery unit.
- DE 196 00 872 A1 it is proposed to sealingly close the opening by a plug, wherein the fuel extraction line and electrical lines are passed through the stopper closing the opening.
- the invention is therefore based on the object to provide a completely novel fuel tank made of thermoplastic material, wherein the number of openings required in the container wall is kept to a minimum.
- a fuel tank made of thermoplastic material, with at least one peripheral seam, with a filling opening, with means for ventilation and with means for conveying and removal of fuel in the form of at least one disposed within the fuel tank fuel delivery unit, with in the fuel tank into and / or out of this out guided fluid lines and / or electrical lines, with no opening and / or no breakthrough in the container wall is provided whose diameter is substantially larger than the diameter of the line in question.
- the fuel tank according to the invention comes without the usual
- the fuel tank according to the invention provides a minimum of potential leakage paths. Leakage in the sense of the invention does not mean the otherwise usual loss of liquid in a visible degree; To understand hydrogen emissions in a barely measurable or barely perceptible area.
- a preferred variant of the fuel tank according to the invention is characterized in that at least one of the fluid lines is connected to a connecting element which passes directly through the tank wall.
- a connecting element may be formed, for example, as a nipple with a fir-tree-shaped profile, which was welded through the container wall by piercing or penetrating with the container wall in the formation of the container.
- the fluid lines and / or electrical lines led out of or into the fuel tank penetrate the seam of the fuel tank at an angle to the course of the seam and / or at least partially through the filling opening and, if appropriate, are guided by a filler neck which adjoins the filling opening.
- this variant of the fuel tank can be provided that, with the exception of the filling opening no openings or openings are provided in the container wall.
- the undisturbed wall portion of the container to understand, but not the seam, on the portions of the container wall are welded together.
- the container may, for example, by thermoforming of two half-switching or through
- the fuel tank according to a variant of the invention is characterized in particular by the fact that, with the exception of the filling opening, a completely undisturbed and unbroken container wall is provided.
- the Fluid lines and electrical lines, which are essential for the operation of the fuel tank, are guided either by the circumferential weld of the container or through the filler neck of the container.
- the invention can be summarized in that the necessary ducts for removal of fuel and venting of the container as well as for electrical lines are arranged in a region of the container, which may constitute a potential leakage point, which can not be avoided due to production reasons.
- the container When manufacturing the fuel tank by extrusion blow molding a tubular preform, the container has a circumferential crimping seam in the region of the division of the tool halves. If the fuel tank is produced from deep-drawn or injection-molded half-shells, a circumferential weld results on a flange-shaped peripheral edge region of the container.
- the fuel tank can also be blow-molded from sheet-like or strip-shaped extrudates, whereby a circumferential seam also results.
- the technique for incorporating the fuel delivery unit and any other required internals into the container will be different.
- the preform may have been blown over the fuel delivery unit in a known manner.
- the fuel delivery unit and all other internals may have been introduced before joining the shells of the fuel tank.
- no inspection opening is provided and the functional fixtures provided in the fuel tank are designed for the entire service life of the fuel tank.
- openings are entirely dispensed with, which would make subsequent access to the interior of the container for maintenance or revision possible.
- the invention therefore takes a completely different route than the prior art.
- a variant of the fuel tank according to the invention it is provided that exactly three fluid lines are fed into or out of the fuel tank.
- the terms "in” or “out” as used in this context refer to the medium carried in the conduit and are not intended to characterize the course of the conduit.
- exactly one filling line, exactly one vent line and exactly one fuel extraction line are provided.
- the vent line can also cover the ventilation function.
- the ventilation and venting line and the fuel extraction line could be routed through the filler neck within a jacket tube provided for this purpose. In this jacket tube and the required electrical lines could be included.
- this is composed of at least two shells which form a flange-like edge in each case in the region of the seam.
- At least one of the lines leading out of or into the fuel tank may extend through the seam in the parting plane of the shells and preferably approximately transversely to the course of the seam.
- the wall of the container may consist of a multilayer extrudate with at least one barrier layer for hydrocarbons.
- At least one line is connected to an insert passing through the seam of the fuel tank, which at least partially consists of plastic and which is welded to the plastic of the container in the seam.
- the insert may for example have been inserted in the connection of the shells of the container between the peripheral edges of the shells and welded to them.
- the insert is designed as a connector.
- FIG. 1 shows a schematic and greatly simplified view of a fuel tank according to the invention after a first
- Figure 2 is a highly simplified schematic view, partially in section, of a fuel tank according to a second embodiment of the invention.
- FIG. 3 shows a sectional view through the wall of the fuel tank and a connecting element passing through the wall in the region.
- the fuel tank 1 according to the invention is shown greatly simplified, so the filling opening usually provided on the fuel tank 1 is shown with a filler neck arranged thereon.
- the fuel tank 1 was manufactured by extrusion blow molding two sheet-shaped extrudates in a multi-stage molding process using a three-piece tool having two outer molds and one middle mold. In the process, two sheet-like extrudates were first placed in the first heat, ie in a still plastic state and without further heating between the outer forms and the middle mold.
- the outer molds each have partial cavities which correspond to the later outer contour of the finished fuel tank. In one step, the outer molds are closed against the central mold, wherein each of the preforms between the outer molds and the central mold are arranged.
- the preforms are expanded within the mold and applied to the inner surfaces of the partial cavities of the outer mold.
- the middle form component holder are within the so manufactured half shells of the container, the functional components required for operating a fuel tank, arranged.
- the outer molds are moved apart, the middle mold is moved away between the outer molds and the outer molds are driven against each other, so that the half-shells of the fuel tank in the region of their flange-like edges 2 welded together.
- the half-shells of the fuel tank 1 are formed of a six-layer co-extrudate with a barrier layer for hydrocarbons embedded therein.
- the fuel tank 1 has a circumferential seam 3, at which the flange-like edges 2 of the half-shells 4a, 4b of the fuel tank 1 are welded together.
- the fuel tank 1 is further provided with a filler pipe 10, which is shown greatly simplified in Figure 2.
- the geometry of the fuel tank 1 in the figures is greatly simplified. It is obvious to the person skilled in the art that the fuel tank 1 can have a relatively rugged and complex outer structure, for example, the fuel tank 1 can be designed as a saddle tank, which has two main volumes in its middle area. The retracted area will usually be arranged in the installation position of the fuel tank on the propeller shaft a car.
- a plurality of bushings 5 are provided in accordance with the invention, which enforce the seam 3 of the fuel tank 1 so that they form an interface of the fuel tank 1.
- These bushings 5 are arranged in a multi-function coupling 6 designed as an insert.
- the multi-function clutch 6 has a base body 7 made of thermoplastic material, which has a total of two feedthroughs 5 and an electrical plug-in contact 8 in the illustrated embodiment.
- the larger of the passages 5 may for example be provided for a vent line, whereas the smaller of the passages 5 may be provided for a fuel extraction line.
- the plug contacts 8 For example, the electrical supply of a fuel delivery unit 11 shown in FIG. 2 can be used and, moreover, the signal of a fill level sensor 12 can be tapped via the plug contacts 8.
- bushings 5 represent the only interface of the fuel tank 1 to the outside. Except this is of course the filler pipe 10, via which a filling of the fuel tank 1 must be made. With the exception of the opening provided in the fuel tank 1 for the filler pipe 10, the wall 9 of the fuel tank 1 is unharmed, i. There are no further breakthroughs.
- the measures provided for in the fuel tank 1 internals in the form of a fuel delivery unit or other functional components are designed for life of the fuel tank 1, in the failure of the entire fuel tank 1 is replaced.
- vent valves 13 are provided, which are connected via a vent line 14 with each other. These vent valves 13 may also be provided in a manner known per se with so-called roll-over valves which close the vent line 14 by gravity.
- the vent line 14, which may be formed, for example, as a refueling vent line, is guided through the filler pipe 10 to the outside. With 19 an electrical line is designated, which is guided at 20 directly through the seam 3 of the container to the outside. Alternatively, of course, electrical lines can be performed through the filler pipe 10.
- the fuel tank 1 according to the invention has no inspection opening, would be accessible by components in the interior of the fuel tank 1.
- connection elements 15 are provided for the connection of one or more fluid lines, which are for example designed as a double nipple and both sides of a circumferential collar 16 each have a pin 17 with a Have fir tree 18 profile.
- the pins serve to choke and attach fluid lines.
- the connecting element 15 was penetrated in the formation of the fuel tank 1 within the tool of the connection element 15. In this case, the connecting element was pushed by means of a manipulator provided for this purpose by the wall 9 of the fuel tank 1 in a mold provided in the die.
- connection element 15 is welded to the wall 9 of the fuel tank.
- the opening, which has been cut through the connection element 15 in the wall 9 of the fuel tank 1, has a diameter which is only slightly larger than the diameter of the connection element 15 or the diameter of the fluid lines to be placed on it.
