fJLTI-STAGE GAS REGULATOR
BACKGROUND OF THE INVENTION
This invention concerns a mlti-stage gas regulator, Firticularlyone used for a fast gas oven having a maternal nuzzle and a main nozzle.
A known conventional oven has a ball valve for controlling respectively gas volume flowing through the maternal nozzle and the main nozzle, comparatively inconvenient to use, unable to quickly regulate hem.
SUMMARY OF THE INVENTION This invention has been devised to offer a multistage gas regulator with an improved structure for controlling gas in various volume flowing through the fraternal and the main nozzle at the same time by turning a shaft of a control member for various definite angles.

DETAILED DESCRIPTION OF TE- INVENTION
A multi-stage gas regulator in te present invention, as shown in Fig. 1, comprises a regulator body 1 having four holes, the first one of them being connected with a gas inlet tube 11 for a gas to come in, the second one being combined with a maternal nozzle 2, the third one being combined with a main nozzle 3, the fourth one being connected with a control member 4 for controlling the gas going through the maternal nozzle 2 and the main nozzle 3.
The maternal nozzle 2 has a nozzle body, a coil spring 21, a valve block 22, a valve rod 23 combined together. The valve rod 23 has one end fitting in one of two annular grooves 44 contacting with the bottom of the groove 44 of a shaft 42 of the control member 4, and the other end resting on to push down the valve block 22 for altering the gap between the valve block 22 and the second hole of the regulator body 1 so as to regulate the volume of gas flowing through the gap. A lighter 24 is provided to light gas coming out of the paternal nozzle 2.
The main nozzle 3 has a threaded body to threadably combine with the third hole of the regulator body 1, a coil spring 31, a valve block 32, and a valve rod 33 combined together. The valve rod 33 has one end fitting in the other groove 44 and contacting with the bottom of the other groove 44 of the shaft 42 of the control member 4, and the other end resting on the valve block 32 to push the block 32 for altering the gap between the valve block 32 and the third hole of the regulator body 1 so as to alter the volume of gas flowing through the gap into the main nozzle 3.
The control member 4 is to be combined with the regulator body 1, having a shaft 42 fixed with and rotated by a turning knob 41 for various definite angles. The shaft 42 has a sealing member 43 to prevent gas from leaking out of the control member 4, two annular grooves 44 spaced apart and having various different depths. The bottoms of the two grooves 4 are respectively elastically urged by the valve rods 23, 33 of the two nozzles 2 and 3, and rotation of the shaft 42 for various definite angles can push down the two valve rods 23 and 33 for different distances, and thus altering the distance respectively between the valve blocks 22 and 32 and the second and the third holes of the regulator body 1 in order to regulate the volume of gas flowing thereout or the size of the flames burning at the two nozzles 2 and 3.
Figure 2 shows that the maternal nozzle 2 and the main nozzle 3 are not yet lighted up with the gas stopped, and the valve blocks 22 and 32 are elastically pushed to block up the second and the third hole of the regulator body 1 so that gas cannot pass therethrough.
Figure 5 shows that the maternal nozzle 2 is opened, but the main nozzle 3 is still closed. Under this condition, the valve rod 23 of the maternal nozzle 2 is pushed down by the shaft 42, so the valve block 22 is also pushed down for a large distance but the valve rod 33 of the main nozzle 3 is not pushed down so that the valve block 32 seals up the third hole cf the regulator body 1.
Figure 8 shows that both the materal and the main nozzle 2 and 3 are at the saar time opened, with the valve rods 23, 33 pushed down by the shaft 42, with the valve blocks 22 and 32 also pushed down for a large distance to let the second and the third hole of the regulator body 1 open for gas to flow out much.
Figure 11 shows that the maternal nozzle 2 is closed up, and the main nozzle 3 is opened. Then the valve rod 23 of the maternal nozzle 2 is not pushed down by the shaft 42, with the valve block 22 blocking up the second hole of the regulator body 1. But the valve rod 33 of the main nozzle 3 is pushed down by the shaft 42, with the valve block 32 separated from the third hole of the regulator body 1 at a large distance to let the gas flow out much.
This invention mainly utilizes the shaft 42 of the control member 4, which is rotated by the turning knob 41, with various depths of the two annular grooves 44 possible to alter the gas flowing through the maternal nozzle 2 and the main nozzle 3.
Claims (5)
1. A multi-stage gas regulator comprising a regulator body having four holes, the first one of said four holes being connected with a gas inlet tube for flammable gas to pass through into the regulator body, the second c::e of said four holes being combined with a maternal ncz-le, the third one of said four holes being combined wrth a main nozzle, the fourth one of said four holes beig connected with a control member to regulate the gas flcing in said maternal and the main nozzle, said maternal nuzzle and said main nozzle both having a nozzle body, a valve rod, a valve block located under the valve rod, a ccF1 spring located under a-c elastically urging the bott= of the valve block, said valve blocks being moved UF and down by the valve rod to open or block up said second and said third holes of said valve body, and characterized by the control member which has a shaft fixed with and rotated by a turning knob, and two annular grooves provided spaced apart on said shaft and having various different depths and being in contact with the tops of said valve rods of said maternal and said main nozzle, rotation of said turning knob together with said shaft for various definite angles altering the position of said valve rods and the valve blocks of said two nozzles so that said valve block may open or block up said second and said third holes of said regulator body in various definite degrees and thus various volumes of gas may be let pass through said two nozzles or stopped completely.
2. A flow regulating device for regulating the flow of a fluid, comprising a body defining a chamber having an inlet port and a plurality of outlet ports, a control member extending into said chamber and moveable relative thereto for causing actuation of respective valve means controlling flow through said outlet ports.
3. A device as claimed in claim 2, wherein each of said valve means comprises a valve block biased into a port closing position and a member moveable by said control member for moving said valve block from said port closing position against said bias.
4. A device as claimed in claim 2 or 3, wherein said chamber is provided with two said outlet ports and progressive movement of said control member causes sequentially a one port to open whilst the other is closed, both ports to open, and said one port to close whilst said other port is open.
5. A multi-stage gas regulator substantially as herein described with reference to the accompanying drawings.
