CONTROL VALVE FOR GASEOUS FUEL BURNERS Filed oct. 7, 1944 Iz/l 0n Position CHARLES M. MAYER.
Patented Jan. 6, 1948 CONTROL VALVE FOR GASEOUS FUEL BURNERS Charlesv M. Mayer, Mansfield, Ohio, assignor to The Tappan Stove Company, Mansfield, Ohio, acorporation of Ohio Application October 7, 1944, Serial No. 557,608
6'Claims. (Cl. 277-32) This invention relates generally to a control l valve for controlling the iiowl of gas to a gas burner and more particularly to a control valve for the top burners of a gas range which is so designed and constructed as to make it possible to obtain either a full llame or a simmer flame at the gas burner.
One of the objects of the invention isl to provide a control valve of the character described which will permit accurate control of the gas admitted to a burner whether' the burner venturi is located at or immediately adjacent the valve, or in a remote location and connected by a tube or pipe. Such aA valve is` particularly desirable with hydrocarbon gases which are delivered at relatively high pressure'andat high heat content per unit volume. ForV example, enough gas is delivered through an orice having a diameter of .025 inch to support a, maximum cooking flame on a top burner. For many cooking operations, it is desired to have a reduced flame and even a very small flame for simmering-L Fora simmer flame, the gas flow isv that permitted through an orice of. about .0.09fto .012 inchv inA diameter or an equivalent gas passageway, Obviously, if this control is attempted by the partial registration of two ports located in the plug and'body of the valve respectively, the slightest rotation of the plug would' at this point enlarge or decrease the opening by a large percentage in comparison to the small totalgas ilow required. Thecontrol of the ame therefore becomes very critical and requires only av slight turn ofthe handlef'rom the off to full position. In my improved valve, I control the flow of gas by means` of a longitudinally movable valve member which is actuated by rotation of thevalve cock so as to obtain accurate adjustment andA any size flame thatV is desired without minuteadjustment.
Another object of the invention is to provide a gas control valve having the above described distinguisliingI featuresand characteristics and which comprises few parts which are well adapted for' production and assembly atr a minimum cost.
Further and more limited objects of the invention will appear asthe description proceeds and by reference to the accompanying drawings in which- Fig. 1 isla vertical sectional view disclosing my improved control valve together with'a top'burn` er for a gas range;
Fig. 2 is f a vertical sectional viewof the control valve proper;
Fig. 3 is a vertical sectionalfviewon theiline 3 3 of Fig- 2;
Fig. 4 is a view in elevation of the longitudinally movable valve member;
Fig. 5 is a sectional view on the line 5 5 of Fig. 4;
Fig. 6 is a fragmentary view in elevation taken on the line 6 6 of Fig. 2;
Fig. '7 is a vertical sectional view taken on the line 'I I of Fig. 2; v
Fig. 8 is a vertical sectional Viewl taken on the line 8 8 of Fig. 2; and
Fig. 9 is a fragmentary sectional view similar to Fig. 2, but showing the valve inthe simmer position.
Referring now to the drawings, the control valve consists essentially of a valve body member' I having an inlet passageway 2 and an outlet passageway 3; The valve body has a generally frusto-conical chamber therein into which i'lts a similar shaped' valve plug 4' which is actuated by a valve stem 5i and a handle 8. A' cap 9 closes the end ofthe valve body and a coil spring I tends to urge the plug toward the left as' seen in Fig. 2. The plug 4 has one or more ports I I therein adapted to be brought into register with the outlet passageway 3. The valve plug 4. is
provided at its inner end with a` circular recess- I2. Threadedly securedin the inlet passageway 2 is a valve member I3 which is shown in detail in Figs. 4 and 5. One end of the valve member I3 ts within the recess I2 and isslidably but nonrotatably secured therein.' The valve member' I3 is provided with an axial'bore I4 anda smaller intersecting radial bore I5`the purpose of which will hereinafter appear. The inner end portion ofthe valve member I3 fits within notches provided within the wall of the chamber I2 `so that a turning movementV of the valve stem 5 imparts a longitudinal movement of the valve member I3 due to its threaded engagement with the walls of the inlet passageway.
Threadedly secured within the end of the inlet passageway is a plug IB having therein an axial bore I 'I which isA disposed in axial alignment with the bore I4 in the valve member I3. A pipe I8 connects the-inlet passageway with the gas intake manifold I9;
In Fig. 2 the valve is shown in the position for permitting a maximum flame at theV burner whichv is determined by the size of the bore II. Due to the fact that the valve member I3 is-somewhat triangularly shaped in section, three passageways are provided betweenthe inner wall of the' inlet passage and the valve member through which the gas may flow; When the'valve is moved to' the position shown in Fig. Zagasfflows through the port I'I in the plug I6 and thence along the valve member into the chamber I2 and thence through the outlet passage 3 through the port II. In this position of the valve, the burner is receiving the maximum amount of gas permitted which is determined by the size of the bore I'I. When the valve is moved to the simmer position shown in Fig. 9, the valve member I3 abuts the machined face of the plug I6 and completely shuts 01T the flow f gas between the faces of these parts, In the simmer position of the valve, the gas will flow through the bore Il, thence through the bore I4, thence through the smaller radial bore l into the chamber I2 and thence through the port II and outlet passage 3. The port I5 is of such size as to permit the flow of .only sunicient gas to maintain a simmer ame. In the oi position of the valve the outlet is closed by a solid portion of the plug 4. The first SiO-degree turn of. the valve plug 4 from the "o-if position brings the parts to the full on position shown in Fig. 2. If the valve handle is moved 90 degrees further in the same direction, the face of the valve member I3 is moved into engagement with the face of the plug I'I so as to permit flow of gas only through the ports I4 and VI5 to provide a simmer flame. In Fig. l there is disclosed a flat top stove 20 having the top burner 2I disposed immediately above the control valve but this arrangement is only illustrative as the control valve may be located elsewhere.
It will now be clear that I have provided a control valve for gas burners which will accomplish the objects of the invention as hereinbefore stated. The embodiment of the invention herein disclosed is to be considered merely as illustrative and not in a limiting sense as various changes may be made in the details of construction and arrangement of parts without departing from the spirit of my invention.
