DE3602079A1 - Device for transferring liquids - Google Patents

Abstract

A device is described, by means of which a liquid can be transferred from one container to another, for example fuel from a metal barrel into the petrol tank of a motor vehicle. The device includes a basic body which has an initial through bore, in which a tubular piece is inserted, and a further through bore with a tubular piece which is connected to a container which contains a pressurised gas. The basic body can be connected in a sealed manner to the screw thread of a metal barrel by means of an outer screw thread. When a propellent flows into the barrel, the liquid contained in the latter is expressed and can be transferred in this fashion to any other container.

Description

The invention relates to a device for decanting

Liquids from one container to another.

The fast and reliable transfer of liquids such as water, Oil, fuel and the like from one container to another is one of many Areas of frequently recurring task. This applies in particular to decanting of fuel from containers such as fuel barrels into the fuel tank of vehicles, such as refueling a tractor or the like in the field or on site. As a rule, the decanting takes place with the help of hand-operated or motor-driven Pump. The speed at which liquids are transferred does not always matter on, but in the case of refilling aircraft in agricultural use The speed of decanting can be of great concern. When using in military areas, the rate of transfer is even extremely high vital meaning. In this area in particular, there is another point special importance, the decanting must be done as noiselessly as possible. In this area is therefore at maximum when refueling tanks during the battle Speed and absolute silence.

The known types of pumps and other commonly used devices these properties are lacking.

While, on the one hand, manually operated pumps work largely noiselessly, but very slowly, motor-driven pumps allow a significantly higher transfer rate, but work very loudly. In addition, the latter are expensive and not always completely reliable.

The object of the present invention is to overcome the disadvantages mentioned above and a very simple, cheap and quiet device to operate to create for transferring liquids According to the invention, this object is achieved by the features in the characterizing part of claim 1 solved.

The device according to the invention is characterized by a very simple one Construction and low manufacturing costs.

It can be operated absolutely noiselessly and can be used to transfer liquids takes place e.g. 10 times faster than with known devices. In particular through the simple construction makes the device highly reliable and they can be operated simply and easily.

The main body of the device according to the invention has a standard screw thread equipped so that the device with appropriately equipped standard barrels can be screwed tight.

The connection line to the container, which contains a pressurized medium, is also provided at its end with a standardized screw cap, which allows a tight connection to the outlet of a standard gas container.

In the following, the invention will be described in more detail with reference to the drawings will. Show it Figure 1 shows the arrangement of the transfer device according to the invention in a fuel barrel with a connected gas container, Figure 2 shows the transfer device according to the invention on average.

In Figures 1 and 2, the arrangement of the device according to the invention shown in a fuel barrel.

The base body 2 of the arrangement is located in the opening 3 of the Container 1. The base body 2 has a cover with a screw thread 2 'is provided to create a tight connection between the base body 2 and the container 1 to manufacture. Furthermore, the base body 2 is provided with a safety valve 4 and an inlet valve 5 is provided, which has a nozzle 6 inside, and over a hose 7 is connected to a gas container 8, which compressed air or contains another propellant gas.

The base body 2 is also provided with a tube 10 that is attached to its one end has a suction pipe 11, while at its other end a flexible hose 12 is connected.

The device works in a simple manner on the siphon principle. Compressed air or a suitable propellant gas (e.g. C92 or natural or town gas) arrives from the container 8 via the line 7 and the nozzle 6 into the container 1, wherein the Flow through the nozzle 6 can be adjusted so that the amount of compressed air or Gas entering container 1 is less than the amount of liquid which flows out of the container 1 via the hose 12. That way you can the low pressure within the container 1 can be maintained.

Experiments show that a 200 liter container takes 24 to 30 seconds can be emptied. Of course, the flow rate can go through Replacing the nozzle 6 can be further regulated. Although security during the Operation of the device is guaranteed, a safety valve 6 is nonetheless provided to maintain and avoid the low pressure in container 1, that a maximum allowable pressure is exceeded.
