Description

Tank with reserve container and procedure for filling and emptying same.

The invention relates to a stationary or in vehicles built-in tank with additional container for storing a reserve amount of fuel or fuel, as well as a method for filling and emptying the reserve container.

Fuel reserves are separated from the fuel in a known manner Main container kept in a reserve canister, which is used, for example, in motor vehicles is housed in the trunk.

If necessary, it is necessary to remove the reserve container there, to open, to be provided with an outlet nozzle, to remove the cap of the potion and empty the fuel into the tank. Afterwards the container must be supplied and at the and taken out again the next time you fill up, filled up and to be supplied again.

Carrying out the type of reserve carried as described above, as well as refueling has disadvantages for drivers in the form of unloading luggage to get to the canister, missing spout, leaked canisters and forgotten refilling of the empty canister are known.

Attempts have already been made to carry reserve tanks with motor vehicles to make it superfluous that you connect the fuel line at the bottom of the tank to a Switchable valve connected to different levels above the tank bottom has, with the valve in reserve position when the main volume of the tank is emptied had to be brought.

The disadvantage of this solution is that it was very often forgotten to reset the valve when refueling and that to maintain the more frequent cleaning had to be carried out due to the free flow.

The task of the procedure described below and the required Devices are to eliminate the identified disadvantages. This happens after the discovery through the arrangement or subsequent placement of a reserve container inside the tank, which is designed so that it is automatically activated each time the tank is filled is topped up or topped up and, if necessary, without the use of additional devices can be emptied from outside inside the tank.

The invention is illustrated by way of example with reference to the accompanying drawings described in more detail schematically in their puncture.

The sectional drawings show: In the Pir 1 Position 1 has a fuel tank of e.g. 60 liters capacity the filler neck 2, the extended neck part 3 and the approx. 5 liter capacity Switch part 4.

Position 5, the connection openings made in the extended nozzle 3 to the interior of the tank 1, as well as 6 the outlet valve which closes under spring pressure.

Position 7 the tank cap 8 attached connecting part to the valve 6 and position 9 a baffle plate.

When filling fuel into the nozzle 2 this fills zwerst the container 4, the bottom valve 6 of which is closed.

After filling, the fuel runs through the openings 5 into the tank 1 and fills this depending on the number of liters supplied.

With the preclusion 8, the connecting piece 2 is preclosed in the usual manner. When reserve fuel is required, the closure 8 is opened and the one attached to it Connection part pulled out so far that the bottom valve 6 against the pressure the built-in spring opens and the tea pulp can flow out into the tank. Normach the tank closure 8 is put back on. The next time you refuel, the Reserve tank refilled automatically.

In Figure 2 position 1 a fuel tank with the tank filler neck 11, in which a plastic nozzle 12 is inserted appropriately.

Position 13 the overflow openings to the tank 10.

Item 14 a bladder made of fuel-resistant, flexible plastic material, which is welded to the connecting piece 12.

Item 13 the plastic rope welded to the bottom of the bladder and Position 16 the special lock to match the socket 12.

The functional sequence is as described in FIG. 1, however in this example, the emptying of the bladder 14 by drawing in the flexible container skin in the direction of the nozzle 12 is made.

Claims (5)

Patent claims: 1.) Procedure for storing, filling and emptying a propellant or fuel reserve in a tank characterized in that within an additional container is arranged in connection with the filler neck of the tank, over which the supplied fuel only after it has been topped up with the appropriate Openings in the tank and, if necessary, an emptying of the additional container into the tank by opening a valve or by reducing its volume is effected from the outside. 2.) Device according to claim 1.) characterized in that it consists of a tank, the inlet nozzle of which goes inwards beyond the tank jacket is extended and / or expanded to a container, the elongated nozzle and / or the container part directly adjoining the nozzle via openings is in communication with the tank room. 3.) Device according to claim 1.) to 2.) characterized in that that in the bottom of the container a valve is arranged so that it is through the filler neck by means of a connecting part attached to the tank lid or to the nozzle end can be opened and closed. 4.) Device according to claim 1.) to 3.) characterized in that that in the upper part of the container below the connection openings to the tank Baffle plate is arranged, which causes the escape of substantial amounts of fuel Prevents vehicle movement. 5.) Device according to claim 1.) characterized in that ze consists of a tank, whose inlet connection is attached to an outer end of the connection, removable inner piece is used, which is after the tank interior over the tank jacket is extended and / or expanded to a container made of flexible material, wherein the elongated nozzle and / or the one directly adjoining the nozzle Container part communicates with the tank space via openings-6.) Device according to claim 5.) characterized in that between the container bottom and the tank nozzle opening or a connecting part is attached to the nozzle closure, with which by train from the outside the volume of the flexible container can be reduced so that the Content but the upper connection openings to the tank / runs out L. e e r e i t e
