April 1, 1958 R. scHoRK rs1-AL GAS BURNER ARRANGEMENT Filed July 14, 1954 United States Patent GAS BURNER ARRANGEMENT Rudolf Schork, Wernau, Kreis Esslingen (Neckar), and Josef Schmid, Ludwigsburg, Germany, assiguors to Firma Junkers & Co. G. m. b. H., Kreis Esslingen, Germany Application July 14, 1954, Serial No. 443,322
Claims priority, appicationGermany July 23, 1953 3 Claims. (Cl. 158-140) The present invention relates to gas burning installations.
In some gas burner installations there is a place adjacent the controls where the gas is always escaping to the atmosphere. This escaping gas, which is combustible, is extremely undesirable because there is always the danger of ignition of this gas. Such ignition will result, for example, in burning of the air to be sucked into the gas burner so that the combustion of the latter is very poor, and moreover the parts of the apparatus become heated to an undesirable extent producing unnecessarily high friction between moving parts.
One of the objects of the present invention is to improve an installation of the above type by preventing gas from leaking to the atmosphere.
Another object of the present invention is to utilize gas which would otherwise leak to the atmosphere.
A further object of the present invention is to arrange the apparatus in such a way that foreign matter cannot fall into the same to disturb the operation thereof.
With the above objects in view the present invention mainly consists of a gas burner arrangement which includes a conduit means for conveying a combustible gas.
A valve means is located in the conduit means for controlling the flow of gas from a part of the conduit means downstream of the valve means to a part of the conduit means upstream of the Valve means. An elongated valve operating member engages the valve means for operating the same, and a guide through which the operating member extends with clearance communicates with the interior of the conduit means so that the gas in the latter the guide is delivered by the duct to the interior of the mixing tube of the gas burner means.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together withradditional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection lwith-the accompanying drawings, in which:
Fig. 1 is a fragmentary, partly sectional, elevational view of one possible apparatus for carrying out the present invention;
Fig. 2 illustrates a different embodiment of the apparatus of Fig. 1; and
Fig. 3 is a sectional elevational view of a third embodiment of an apparatus constructed in accordance with the present invention.
Referring now to the drawings, the embodiment of Patented Apr. l, l1958 r6 ICC 2 Fig. 1 includes a gas valve housing 1 part of which is formed by a conduit 2 connected to a source of combustible gas by the dotted line conduit shown inthe lower portion of Fig. l. The conduit 3 conveys combustible gas to burners not shown in the drawings, the valve member 4 controlling the ilow of gas from the conduit` means located downstream of valve 4 to the conduit 3 located upstream of valve 4. This valve 4 is urged to its closed position by the spring 5 and is engaged by an elongated valve moving member in the form of rod 6. This rod 6 extends upwardly from valve member 4 and in the embodiment of Fig. 1 carries at itsrtop end a projectionv which is engaged by a bimetallic strip 7. As is shown in Fig. l, a llame, indicated in dotted lines, heats a member which transfers its heat to the strip 7 to cause the this bore 9 the guide 10 is formed with an enlarged continuation of bore 9 leading to the outer atmosphere so'Y that the gas leaking through bore 9 would simply low` to the outer atmosphere were it not for the structure of the invention described below. The enlarged continuation of bore 9 yis formed in a member 11 screwed into the outer sleeve of guide 10. The member 11 is formed with a cutout 12 which serves to provide a communication between bore 9 and the continuation thereof and a duct 13 connected at its left end, as viewed in Fig. 1, to the guide 10. The opposite end of duct 13 communicates with the primary air suction opening in the mixing tube of a gas burner 8.
The gas owing to the outlet nozzle of burner S sucks not only the gas leaking through bore 9 but also sucks into the mixing tube of burner 8 primary air derived through the enlarged continuation of bore 9, as is evident from Fig. 1. The burner 8 communicates directly with the conduit shown in dotted lines in Fig. 1 so that the supply of gas to burner 8 is uninlluenced by valve 4.
. It will be 4noted that with this arrangement the duct 13 determines the position of burner 8 and controls its d's'- tance from Vbimetallic strip 7.
The embodiment illustrated in Fig. 2 differs from that of Fig. 1 only in that the top end of guide 10 is covered so that downwardly falling foreign matter, falling, for example, from a heat exchanger located over pin 6, cannot fall into the guide and create disturbances. Thus,
instead of being open at the top, the embodiment of Fig;
2 is provided `adjacent the closed top of guide 10 with lateral openings 14 communicating with the outer atmosphere.
According to the embodiment shown in Fig. 3, a unitary valve arrangement is provided. Thus, the valve housing 1 is formed with a passage constituting the conduits 2' and 3 respectively located downstream and upstream` strip 7 to be operated thereby in'the manner described above. The guide bore 9 which forms a guide for the pin 6 is of somewhat larger cross section than the latter so that gas escapes through bore 9 when valve 4' is open. The guide of Fig. 3 further includes the member 11 carried by housing 1 and formed with an axial bore through which pin 6' slidably extends. The burner 8 also is carried by housing 1 and communicates with the gas passage downstream of valve 4 through an inclined bore formed in the housing 1', as shown in Fig. 3. This burner 8 further communicates with one end of a bore duct for the primary air sucked into the mixing tube of burner 8. The bore l5 extends across bore 9 and has its lower end, as viewed in Fig. 3, in communication with the outer atmosphere. Thus, air sucked into burner 8 along bore'lwill also draw into burner 8 gas which leaks through the bore 9', so that the embodiment of Fig. 3 produces the same results as the embodiments of Figs. l and 2. Furthermore, when the embodiment of Fig. 3 is in its operating position shown in Fig. 3, the location of the inlet end of bore 15 Ybeneath bore 9 and pin 6 prevents foreign matter from entering into the apparatus.
It will be seen that the structure of the invention prevents an uncontrolled escape of gas and in addition sucks this escaping gas with the gas mixing in the burner S or 8' so that even when rich gases such as propane or butane, which are heavier than air, are used, the leaking gas is efficiently delivered to the burner 8 or 8 and cannot cause any undesirable results.
It will be understood that each of the elements described above, or two or more together, may also ind a useful application in other types of gas burners diftering from the types described above.
While the invention has been illustrated and described as embodied in valve arrangement for gas burners, it is not intended t-o be limited to thedetails shown, since various modifications and structural changes may be made without departing in any Way from the spirit of the present invention,
Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitutes essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
