fif/ Patented June 18, 1946 DEVICE FOR SUPPLYING A PREDETER- MINED AMOUNT OF LIQUID Carl Bernhard Holm, Roslags-Nasby, Sweden Original application January 29, 1938, Serial No. 187,767. Divided and this application October 11, 1941, Serial No. 414,691.
This invention relates to devices for supplying a predetermined amount of liquid to a certain place for example to devices associated with burners for vaporised fuel for producing primary vaporisation and ignition.
For the ignition of such burners used for example in petrol stoves and the like a separate igniting liquid, for example alcohol, is generally used, which is ignited in an ignition cup arranged below the burner head in order to preheat the burner.
The object of the invention is to provide a device wherein a quantity within predetermined limits of the igniting liquid is supplied automatically to the ignition cup each time the burner is ignited.
According to the present invention the device for supplying a predetermined amount of igniting liquid into the ignition cup of a burner for vaporised fuels includes a vessel closed at the bottom and open at the top and having its lower part communicating through a conduit with the liquid space of a container 'for igniting liquid, and a measuring chamber which is in communication with the upper part of the vessel and has its lower part connected to the ignition cup and its upper part communicating in a controlled manner with a compressed air source.
The said device according to the invention preferably comprises an igniting fuel container supplying liquid through a liquid trap to a measuring chamber having its lower part communicating with the ignition cup of the burner and means to supply compressed air at will to the upper part of said chamber.
By the term liquid trap herein used is to be understood a liquid seal acting to prevent back flow of liquid from the measuring chamber to the igniting fuel container on the introduction of compressed air into the measuring chamber.
The invention will be hereinafter more fully described with reference to the accompanying drawing showing one embodiment of the invention in section.
Referring to the drawing a container for the igniting liquid exposed to atmospheric pressure is indicated by l. A conduit 2 connected to the base of this container leads into the lower part of a vessel 3 open at the top and closed at the bottom which is arranged within a closed vessel 4. The vessel 4 is connected at its base by means of a conduit 5 to an ignition cup (not illustrated) and its upper part is connected through a conduit 6 and a shut-off valve 1 arranged in the latter conduit with the air space of a fuel con- 2 Claims.
In Sweden July tainer exposed to pressure above atmospheric which is not illustrated in the drawing. The vessel 3 thus forms a. liquid trap the overflow from which passes into the annular space between the vessels 3 and 4 which annular space comprises a measuring chamber. This application is a division of application Serial Number 187,767, filed January 29, 1938, which has matured into Patent Number 2,268,591.
The above-described device operates in the following manner.
Since the conduit 5 is open, it is filled with igniting liquid, when the valve 1 is closed, up to a height corresponding to the liquid level in the container l. The vessels 3 and 4 are thus completely filled. ,In order to supply igniting liquid through conduit 5 to the ignition cup (not shown) the valve 1 is opened. Compressed air then flows from the fuel'container which, as above stated, is not shown through the valve 1 and conduit 6 into the vessel 4 and thus presses the amount of liquid which is present in the measuring chamber intermediate the vessels 3 and 4 through the conduit 5 into the ignition cup. The amount of liquid which is present in the vessel 3 is at the same time forced upwardly due to the pressure of the compressed air into the liquid container I.
When the valve 1 is subsequently closed, and the air in the conduit 6 and vessels 3 and 4 escapes through the threads of the valve 1 igniting liquid again flows by gravity into the vessels 3 and 4 from the container I. In this way the ignition cup is supplied each time the valve 1 is opened with the same amount which corresponds to the volume of the annular space between the walls of the vessels 3 and 4. 7
While the source of pressure has been described as a fuel container at a pressure above atmospheric it is obvious that the conduit 6 may also be connected to an air pump or the like which can be actuated manually or otherwise.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I de clare that what I claim is:
1. In combination, a container for ignition liquid communicating with the atmosphere, a vessel having a closed bottom and an open top, a conduit connecting the container with the lower part of the vessel, a second vessel enclosing the first said vessel and forming a measuring chamber between the two, the open top of the first named vessel communicating with the top of the chamber, liquid conducting means connected with the lower'part of the chamber, a conduit and part of the vessel, a second vessel forming a Ineasuring chamber, the open top of the first named vessel communicating with the top of the chamber, liquid conducting means connected with tne lower part of the chamber, a conduit and valve controlled means for admitting pressure fluid to the upper part of said chamber.
