Installation and removable sealing protective ring in filler necks, in particular for motor vehicles

The invention relates to a sealing Schutsring that vehicles in the filler neck of motor is arranged o

Through the modern filling station network and its design, through the self-refueling of motor vehicles by the driver or passenger, this happens as follows during the refueling process:

■ i 4

As soon as the driver or the passenger has the fuel gun from, the fuel pump lifts and leads into the opening of the filler neck of the motor vehicle, flows the leaded fuel from the fuel gun through the filler neck to the tank of the motor vehicle. There in the usual simple way this work process in a stooped or slightly forward leaning posture is carried out by the above-mentioned persons to be carried out, flow out during the refueling process between the filler nozzle and the tank gun, toxins that find their way through the respiratory system to the lungs. The bent forward posture and the front position of the driver or passenger when refueling the vehicle thus offers the toxic, flowing and harmful exhaust gases a target. It becomes almost tragic in hot weather, when the leaded gasoline exhaust gases hit back - in intensified Dimensions are inhaled directly through this process - and the ones worn during the refueling process Clothing becomes soiled, which then follows Excitements are often uncomfortable.

It is still controversial which harmful ones

j Effects of the lead content on people,

\ The fact is that by inhaling the lead -

t containing toxins damage the overall respiratory system

of the human body - especially in the lungs have occurred and have been proven »By the year 199o, according to preliminary estimates, ϊ do not reduce the lead content in fuel -

increase due to the increased consumption.

The invention has therefore set itself the task of counteracting these listed - and for people, especially for the group of people who undertake the refueling of the vehicles - occurring harmful disadvantages as well as possible. E ₃ should be a solution, which is characterized in that an ah sealing protective ring with an insert or

a connector in the filler neck for power '|

Vehicles of all kinds or the like to create and train so that this is particularly easy and economical producible and used in the above-mentioned filler necks of motor vehicles of all kinds can be.

Solution task:

The invention solves the problem of the type mentioned and mentioned at the beginning d_a d_u_r_c_h that a sealable protective ring that can be installed and removed in filler necks, especially for motor vehicles the essential components, the protective ring, the insert piece and the tapered extension piece is formed, which has the connection in the upper Be rich of the filler neck groove and demands, or is formed with a bead all around, which lies on the upper edge of the filler neck- and can thus be locked while the insert piece

in the lower area has a recess that the ^!

additional clamping ring accommodates and in connection with

the conically arranged extension piece the tank - |

pistol while the vehicle is being refueled Hermetically sealed so that the toxic gasoline exhaust gases are bound and not inhaled

Furthermore, the invention is characterized in that the protective ring, which is located under the lock for · the Tank lock of the filler neck engages rich in the upper Be has an annular bead-like reinforcement. A special feature of the invention is there rin recognized that the sealing protective ring for filler neck in motor vehicles or the like. With egg nem own insert can be arranged, that is then formed all around with adhesive knobs, »

The invention is advantageously characterized in that the conical, tapered and sleeve-like extension piece is arranged and in the lower area a hollow screen does not allow the finest particles to flow into the tank ο

Another advantage of the invention is seen in the fact that in connection with the seal in the insert Protective ring are arranged on the inside with adhesive knobs that close with the cuff-like extension piece are suitable for holding the fuel gun during the refueling process.

A particularly important feature of the invention is seen in the fact that a level indicator within of the insert that is to indicate that the tank is filled with fuel to prevent the gasoline from overflowing «

The invention and the advantageous details of the invention are described below with reference to drawings and the exemplary embodiments explained in more detail:

Fig. 1 shows the sealing protective ring with

the insert that lies in the upper area of the filler neck

Fig. 2 shows the sealing protective ring with

the arranged tapered extension piece, the cuff-like ge forms is, furthermore the filling indicator and the introduced tank pistol

Fig. 3 shows the sealing protective ring with

the insert, the conical extension piece, with the arranged Hollow sieve

In Fig. 1, a protective ring or the sealing protective ring with the reference number 1 is assigned and with an insert 2 shown, on the circumference in the front upper area for connecting serving before jumps, like tongue and groove, 3 »3» arranged that are

extend outwards. Furthermore, in the protective ring 1, for the filler neck 4 in connection with the insert 2 recesses 18 for receiving the air line 6 and the gasoline overflow line 6, arranged. To connect the Schtttzringes 1 with the filler neck 4, the protective ring is bead-like 7, while the bead-like elaboration 7 is a fine one Steel snap ring 8 is arranged, which attaches the protective ring 1 to the upper edge 9 of the filler neck 4 presses under the lock for the tank lock. In addition, holding or clamping pieces 1o, 1o * are made from the material Material in the surrounding wall 11 of the Protective ring 1 angeordent, which have the task of securing the protective ring 1 to the upper Eand 9 of the filling nozzle 4 to clamp and hold.

In Fig. 2, an embodiment is shown, the protective ring 1 for the filler neck 4 with the associated insert 2 to show. The insert piece 2 is a conically elongated extension part 12 assigned that is cuff-like ge forms. The fiery resilience of the cuff-like Part 13 of the tapered extension piece 12 has its effect in that the Tank pistol 14 as it is inserted into the filler neck 4 is exposed to a holding resistance and sugleich with the sleeve-like training 13, des Extension piece, the fuel flow between the filler neck 4 and the fuel nozzle 14 hermetically sealed so that the gasoline exhaust gases are not inhaled will.

Furthermore, from this embodiment he can be recognized, in the insert 2 made of the material's own material, a level indicator 2o to be arranged, the Show the fueling process, by means of a pip tone or a whistle tone, when the tank is full. This arrangement of a level indicator 2o also prevents the fuel from overflowing. The leaded gasoline leaves no traces on the paintwork of the bodywork, nor does it leave white streaks, which which often annoy the owner of the motor vehicle through these defective areas - and later at the sale of the vehicle result in a lower price.

As can be seen from FIG. 3, a protective ring 1 for filler neck 4 is shown, which is located on the upper edge of the enclosure 11 has a bead 16 all around - and with this bead 16 on the upper edge 9 of the Filler neck3 4 is attached. Further is from oneself Offering security reasons in the lower part of the insert 2, a recess 17 is arranged, the one receives further safety ring 19, which is given the task that stole when pulling out the Tankpi 14 from the cuff-like extension piece 13 exposed to a resistance in front of the insert 2 and prevents the sealing protective ring 1 from being released from the filler neck 4. Furthermore, it can be seen from Fig. 3 that in the lower region of the tapered extension piece 12 a hollow screen 15 comes to the arrangement that the finest Particles of the fuel (especially with diesel)

do not flow into the tank, as this will damage the fuel line becomes clogged and annoyed a great many drivers.

In practice it will be useful in structural terms
Embodiment of the invention to combine the sealing protective ring 1, the extension piece 2 and the conically tapering extension piece 12 with the arranged hollow screen 15 to form a structural unit for reasons of economy.

The invention is not abandoned if for reasons the cost saving of the sealing protective ring 1, in conjunction with a tapered extension piece 12, with and without hollow screen 15, optionally for use comes.
