Definitions

• the invention relates to a connection hose between two containers, said hose comprising a liquid channel and an air channel and having connection pieces for tight fastening in the container spouts, and where the one container in the filling position is raised above the other container so that the liquid can be transferred from the upper to the lower container.
• inflammable liquid such as engine fuel (petrol) or the like
• inflammable liquid such as engine fuel (petrol) or the like
• a certain risk is always connected with such a filling operation.
• the filling can be effected via a funnel which is placed in the spout of the tank, and into which the fuel is poured carefully from the discharge spout on the container.
• a hose is secured to the container spout and this hose is inserted down into the tank, after which the fuel is made to flow by an appropriate lifting of the container.
• the air hose opens out above the surface of the liquid, in order for the air to be able to escape from the hose when the discharge is initiated at the start of the filling. There is no "free flow" for the liquid, the reason being that the air is restricted by the thin hose and by its passage through the pipe, which reduces the filling capacity.
• connection hose which comprises a liquid channel and an air channel, and where the liquid channel and the air channel have the same cross-sectional area, and the air channel is extended in such a manner that it projects up above the liquid channel in the filling position.
• fig. 1 shows a connection hose mounted between two containers during the transfer of liquid from the upper to the lower container
• fig. 2 shows an example of a connection hose.
• connection hose 4 In figs. 1 and 2 there is shown a preferred embodiment of a connection hose 4 according to the invention.
• This comprises a piece of twin hose, preferably executed in a flexible, transparent synthetic material, and where there is a liquid channel 5 and an air channel 6 which have the same sectional area.
• the hose 4 is mounted between two truncated coneshaped plugs 3, 7. At the upper end, the air channel 6 is extended.
• both the air and the liquid channels are extended for a suitable distance in order to determine the maximum liquid level, shown with a stippled line in fig. 1, that the liquid 2 can reach in the container 1 after the filling.
• the plugs 3, 7 are preferably made of an elastic plastic foam with a skin-like surface, such as polyurethane on ether base. In the plug there is a tight fit for the hose 4, which passes tightly through the plug.
• This configuration ensures that a plug can be pressed easily into the spout on a container, and that it remains here firmly and tightly during the filling. After use, the plug can be wriggled out of its engagement and is able to be used again and again without becoming leaky.
• connection hose When in use, the connection hose is mounted on the spouts of the two containers by means of the cone -shaped plugs, hereby providing a completely closed circuit between the containers. It is a condition for the correct function that all joints are absolutely tight.
• connection hose is mounted so that the inlet is effected through that end at which the air channel 6 extends up over the liquid channel 5 when the container 10 is lifted and tipped, as shown in fig. 1.
• the difference in height between the inlets of the two channels 5, 6 results in a higher pressure in the lower channel 5 than in the higher channel 6, whereby the air from the lower container 1 will be pressed up through the channel 6 because of the lower pressure in this channel.
• this channel is more or less filled with liquid, which is therefore pressed up through the channel and out in the upper container.
• the amount of air which is evacuated from the container 1 will be equal to the amount of liquid admitted to the container. Moreover, the liquid is separated from the air, and is thus not disturbed by the passage of the air up through the down -flowing liquid.
• the liquid can be made to run out of the hose and down into the containers, without the need for as much as a drop of liquid being spilt, and moreover without the escape of undue amounts of vapour.
• the latter is solely a question of how quickly this part of the operation can be carried out.
• the spout is provided with a cap, and the filling has been completed in a safe, clean and simple manner.
• the use can be envisaged of plugs to which the hose is secured by welding or the like, in that the hose does not need to pass through the plug, but can end at the plug.
• the air channel, which must be extended, can be secured to the one plug's opposite end, for example by welding or the like.
