Description

Device for mixing fuel and 01 during the refueling of motor vehicles operated with mixtures object of the patent o66 828 is a device for mixing fuel and 01 during the refueling of motor vehicles which are operated with so-called mixture. This device consists of a set up for continuous mix freely movable mixing vessel with an inlet for fuel and 01, one of the 01 receiving, equipped with overflow and learning of (tapered fuel beaufschlag: en mixing chamber and a standing with the mixing chamber in connection downcomer for the final mixture The device, which forms a whole, can be placed directly on the fuel tank of the motor vehicle to be refueled.

Such a device is to be further developed in particular. <let a loosening and washing away of most of the oil already in the first Mixing phase due to the fuel flowing into the mixing chamber in an excessively sharp jet prevented and that a perfect mixing is also ensured then if the device is not exactly perpendicular to the fuel tank of the tank to be refueled Motor vehicle is put on. Accordingly, the invention seeks dissolution and mixing of fuel and oil for practically all or most of the inflow time of fuel to expand. The invention also aims to purify the Device can be made even easier.

To improve the mixing process, the invention proposes one within the mixing and receiving container for the oil, below the one in the upper part of the container located overflow arranged funnel-shaped intermediate wall before with a central opening and one in the area thereof in a certain inclined position attached baffle plate.

This results in too rapid an outflow of the aggregate through the overflow prevents and at the same time the swirling of the oil by the fuel jet promoted. Because the fuel jet is already split before it joins the one in it If the oil to be dissolved comes into contact, the device will work properly even if it z. B. in an urgent refueling or for other reasons more or less is inserted at an angle into the filler opening of the fuel tank.

In a further embodiment of the invention is at a small distance about the funnel-shaped bottom of the mixing and receiving container an open top and bottom Conical shell arranged, the so far the flow processes during the mixing process influenced as he made a lively movement and a pull even in the so far relatively brings dead side spaces of the mixing and receiving container and thus a more intensive Forcing mixing.

According to another proposal of the invention is in the lower end of the holding bar on which the mixing and receiving container is placed Sieve arranged, which together with its tire-like edge can be unscrewed after removing the trained drain nozzle can be removed from its holder. Through this additional benefits are achieved. The arrangement of a sieve on the one just marked Position causes a filtering of the mixture shortly before its final transfer into the fuel tank of the fueled vehicle, thereby simultaneously it is ensured that no undissolved oil parts escape. By that simply That is what has to be done by unscrewing and reattaching the drainage nozzle called sieve very accessible, so that it can be monitored at all times from the sieve residues can be released.

Finally, the subject of the invention is a special training the sieve rim or the holder for the sieve. The sieve rim and / or the holder are provided with cutouts at the bottom over the entire circumference through which a roughly serrated edge surface is formed. This ensures that during a refueling operation even the last remnants of the mixture come to drain and put in the fuel container of the vehicle, so that there is a guarantee that the customer of the gas station also actually gets the full amount of fuel he wants.

Finally, the device forming the subject of the main patent is obtained Another improvement in the following point: In the previous design of the device can possibly at a certain point in the upper part, namely where The mixing and receiving container, which can be moved in a vertical direction, is located in the outer jacket sliding leads, rainwater enter. According to the invention a on the filler neck of the Fastened mixing and receiving container, overlapping said sliding point inclined collar provided, which is guided around the entire filler neck. This Collar repels rainwater to the outside and reliably prevents that, too when it rains very heavily, water, even if only in small amounts, into that Can penetrate the inside of the device and mix with the fuel.

Further features of the invention and details of those achieved by it Advantages result from the following description of the in the drawing in Section shown embodiment of the device.

The cylindrical. @ Ußeilmantel i runs conically in the upper part 2 to. In the funnel-shaped bottom 3 a GeNvindehals .I is used, in which the one provided at the top with a thread, in the fuel container 6 of the to be refueled Motor vehicle usable drain pipe 5 can be screwed.

The outer jacket i encloses the smaller mixing and receiving container 7 for the oil. This is in the vertical direction by pressing down the lever 8 displaceable against the action of the spring y. Rests in the lowered position it on the retaining bar io, which is provided with a seal> i.

The filler neck 1 2 of the container 7 can be closed by the cover 13. An intermediate wall 15 is arranged below the overflow 14 of the container 7 with a central opening in which a baffle plate 16 is attached in an inclined position is.

Located at a distance above the funnel-shaped bottom of the container 7 the cone jacket 17. The sieve 18 is inserted into the lower end of the retaining web, the edge and, if necessary, the holder is provided with cutouts. Through this a roughly serrated edge surface is formed, with tips i9 of the individual serrations are directed downwards.

On the filler neck 12, the circumferential collar 2o is attached, the the upper edge 2 of the outer jacket i covers.

The device works as follows: After placing the device on the Fuel tank 6 of the vehicle to be refueled and the lid opened 13 is first the necessary amount of oil z. B. by emptying an oil can the filler neck id introduced into the container 7. After the empty oil can has been removed, the hose of the fuel pump with a filler cock is inserted into the filler neck 12 introduced. When refueling, the fuel first hits the baffle plate 16 and flows in a distributed manner into the lower part of the container, in which the through the Conical jacket 17 favored mixing with the oil takes place. The mixture is through the partition 15 deflected once more before it over the central opening in the partition 15 and through the overflow 14 into the annular space between the outer jacket i and the container 7 flows downwards. Before the final outflow through the Drainage port 5, the mixture passes through the removably arranged sieve i8.
