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 previously separated from the main container in a known manner in a reserve canister, for example in the trunk of a motor vehicle is housed.

If necessary, it is necessary to remove the reserve container there, to be opened, to be provided with an outlet nozzle, to remove the tank cap and empty the fuel into the tank. Afterwards the container must be supplied and be fetched again at the next bank, replenished and supplied again.

Carrying out the type of reserve carried as described above, as well as refueling has disadvantages that driving a car in the form of unloading luggage, to get to the canister, missing spout.

Leaked canisters and forgotten refilling of the I emptied Canisters are known.

Attempts have already been made to carry reserve tanks with motor vehicles thereby making it superfluous that you connect the fuel line to the bottom of the tank switchable valve leading to different levels above the tank bottom connected, -which then when emptying the main amount of the tank contents that The valve must be brought into reserve position.

had to.

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

The task of the procedure described below and the required Devices is to eliminate the disadvantages indicated. This happens after - The invention by the arrangement or subsequent accommodation of a reserve container inside the tank, which is designed to automatically refill each time the tank is filled. or anchfilled and if necessary without the use of additional devices Action can be emptied from the outside inside the tank.

The reserve container can be arranged in two ways. Either the container is already used when the new tank is manufactured within the Tanks are attached to the tank wall or to the filler neck, or it is retrofitted introduced the filler neck as a separate part and attached to this attached.

It is essential in both cases that the reserve tank is at normal refueling without doing anything. When attaching the container to the tank sets this assumes that it is placed in the lower part, so that the fuel also then can enter, for example, if the tank is only half full.

If necessary, the reserve container can be emptied in two ways take place and that once directly by actuating the emptying mechanism by hand on the tank, for example by a connecting part to the tank cap or in motor vehicles preferably by remote control from the driver's seat, for example by a Bowden cable The invention is illustrated using the accompanying drawings, for example schematically described in more detail in their function.

It shows in the sectional drawings: In figure. 1 position 1 one Fuel tank with a capacity of 60 liters, for example, with the filler neck 2, the extended nozzle part 3 and the approx. 5 liter container part 4.

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

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

When filling fuel into the nozzle 2, the latter fills first 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 closure 8, the nozzle 2 in the usual way locked. Reserve fuel if necessary the closure 8 is opened and the connecting part attached to it is pulled out so far, that the bottom valve 6 opens against the pressure of the built-in spring and the Fuel can flow out into the tank. Afterwards the tank cap 8 is again put on. The reserve tank will then be automatic again the next time you refuel filled.

In Figure 2, position 10, 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 fibrous tissue-resistant, flexible plastic material, which is welded to the connecting piece 12.

Position 15 the plastic rope welded to the bottom of the bladder and Position 16 the special lock to match the insert socket 12.

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

In Figure 3 position 17 a fuel tank with one through the wall 18 separate reserve chamber 19, which is provided with inlet openings at 20, through which the fuel filled into the main space 21 'can enter.

Position 22 the outlet valve, which by means of the Bowden cable 23 from Driver's seat can be opened and closed.

Claims (9)

Patent claims: 1.) Procedure for storing, filling and emptying a propellant or fuel reserve in a tank characterized in that within of the tank, an additional container with connection openings to the tank space is arranged and the supplied fuel is either first filled into the auxiliary container and via its connection openings to the tank room or vice versa first into the tank room and then enters the additional container and, if necessary, emptying the Additional container takes place directly in the tank. 2.) Method according to claim 1.) characterized in that the emptying of the reserve container into the tank via the inlet openings by reducing its size Internal volume takes place from the outside. 3.) Method according to claim 1.) characterized in that the emptying the reserve container into the tank through a lockable opening on the bottom of the container takes place. 4.) Device according to claim 1.) to 3.) characterized in that that it consists of a tank, the inlet nozzle of which goes inwards over the tank jacket is extended addition and / or expanded to a container, the extended Nozzle and / or the container part directly adjoining the nozzle Opening on is in communication with the tank room. 5.) Device according to claim 1.) to 3.) through this characterizedf that a valve is arranged in the bottom of the container so that it through the filler neck by means of a attached to the tank cap or to the nozzle end Connection part can be opened and closed. 6.) 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. 7.)
