  • the control valve or the control valve may be connected in parallel with an adjustable bypass device.
  • the control valve for the first gas burner is connected in parallel, so that even in the case that closes during the temperature-controlled operation, the control valve passes through the bypass means a certain small gas flow to the first gas burner and this, at least with a kind of pilot flame , keeps on burning.
  • no reignition must take place, but this then increases its performance just according to the stronger gas flow.
  • this is known to those skilled in principle, for example from the aforementioned DE 102013218014 ,

  • control valve in the control valve or in the control valve body is a very space-saving design possible. Furthermore, this also simplifies a gas flow, since less complicated gas ducts or gas ducts in the gas valve housing, which is preferably made as far as possible from a solid piece of metal, must be provided.
  • the thermostat drive sits on the rotary shaft itself.
  • a rotary shaft is mounted relatively stable and stable on the gas valve device or in the gas valve housing, whereby such storage is also made possible for the thermostat drive.
  • the thermostat drive can in the usual way have an expansion body, which is advantageously flat and is preferably designed in the manner of a double disc or a flat drum. This expansion body is connected at its top to the rotary shaft. On its underside it is connected to the control valve body. One of the two connections can be fixed or even insoluble, for example by welding.
  • the other connection can be either solvable or even realized only with a pressure system, so that ultimately the thermostat drive exerts pressure on the control valve when regulating, for example, to close.
  • a control valve seat spring By its own spring, such as a control valve seat spring means, the control valve can be pressed in the open position and in the direction of the thermostat drive.
  • a defined position of the control valve is adjustable.

  • the control valve body may be provided with an aforementioned control valve seat spring means.
  • the overpressure spring means serves to protect thermostat drive and control valve from damage due to excessive forces
  • the control valve seat spring means serves to open the control valve with the space created when withdrawing or retreating the thermostat drive with the resulting space or to open the control valve body from the control valve seat to the stop on the thermostat drive.
  • the spring force of the control valve seat spring means should be less than that of the overpressure spring means, so that the control valve actually opens only as far as it allows the thermostat drive as a kind of stop.

  • the manual handle is arranged at the front, for example on a control panel of the gas appliance.
  • a shut-off valve may be provided in the gas valve device, in particular in order to interrupt the gas flow as a safety function when extinguishing a flame on a gas burner, so that no more gas reaches this or even one of the gas burners.

  • Such a check valve may be formed as a known solenoid valve and, for example, be opened manually at the beginning of the operation of the gas burner and kept open.
  • a coil of the solenoid valve is connected to a thermocouple close to one of the gas burners, so that with sufficient heat generation at the gas burner after a few seconds of operation, a thermo-current flows as a holding current through the coil to keep the shut-off valve so to speak automatically open. Only when the gas flame extinguishes and thus ends the heat generation at the gas burner, detached from a further existing gas flow, the Thermostrom stops flowing and the shut-off valve closes and blocks any gas flow out of the gas valve device.
  • the rotary shaft can be mounted by means of a thread on the gas valve housing so that it tends to open the control valve stronger depending on the rotational position or closes stronger.
  • a rotation of the rotary shaft can be provided starting from a zero position in a direction of rotation.

  • the driver is fixedly arranged on the rotary shaft, so that it exerts only one torque on the control valve body, but no force in the axial direction.
  • the rotary shaft by means of an aforementioned thread further into the gas valve housing in or out of it, so the force generated thereby should not be transferred to the control valve body.

  • this bypass gas flow can bridge the control gas flow to still supply the first gas burner with some gas when the control valve is closed, to keep it from burning.
  • gas supply to the second gas burner can run outside of the control valve body channels.

On a rotary shaft 30 of the rotary knob 21 is placed as a manual handle.
  • the gas valve device 20 is also provided with a first thermocouple 40 near the first gas burner 15 with a first conduit 41 and with a second thermocouple 43 near the first second gas burner 17 connected to a second line 44. These thermocouples are used to switch off the gas valve device 20 if the temperature at them drops so far that their associated gas burner is not in operation. So this is a known security measure. Furthermore, a liquid tube 46 is connected as a temperature detection means of a liquid line 36 to the gas valve device 20. These serve a thermostat drive described above.
  • FIG. 3 a detailed illustration of the gas valve device 20 is shown.

  • thermostat drive 34 At the lower end of the rotary shaft 30 of the thermostat drive 34 is arranged.
  • This thermostat drive 34 can also be taken from the aforementioned prior art, which is why it is treated only briefly. It has an expansion body 35 in the manner of a concentric multiple corrugated double disc. From above, the liquid line 36 leads from the aforementioned liquid reservoir 46, and the liquid contained therein is also contained in the interior of the double disc of the expansion body 35.
  • a gripper 37 is provided, in the interior of which an overpressure spring 38 is arranged as a helical spring. The gripper 37 engages the control valve 49 in order to pull it up positively. Down can be exerted on the control valve 49 pressure not directly from the gripper 37, but only by the pressure-spring 38. But this is sufficient to close the control valve 49th
  • the control valve 49 in turn, has a control valve seat 50 against which a control valve body 51 of the control valve 49 is driven, moved by the thermostat actuator 34.
  • the control valve body 51 is supported downwardly with a control valve seat spring 53 which causes the control valve 49 opens.
  • the control valve seat spring 53 is designed as a helical spring, but with a much weaker spring force than the pressure spring 38, as previously explained. The difference in spring force can be 1.2 to 2 or 3 times.

  • the function of the adjustment via the rotary knob 21 on the control valve is obviously recognizable. If the rotary knob 21 is moved in one direction, for example in the counterclockwise direction, the rotary shaft 30 is slightly moved out of a normal thread between the rotary shaft 30 and the adjusting nut 32. It thus opens the control valve 49 via the gripper 37, since the control valve body 51 is lifted from the control valve seat 50. At the same time the check valve 24 is opened, for example via the manual opener 25, which should be automatically pressed or pressed in a known manner via a lever or other power transmission device when pressing the rotary knob 21. The further the rotary knob 21 is rotated, the more the control valve opens.
  • the liquid has the thermostat drive 34 causes a certain extent of the expansion body 35 and thus a certain Move down. If this has gone so far that the control valve body 51 rests against the control valve seat 50 and the control valve 49 closes, occurs on the first Gas outlet 27 no more gas. The temperature in the oven muffle 12 goes back, and the control process continues in a known manner.
  • a bypass screw 55 is provided as the aforementioned bypass means. It is a long screw with a thin bypass bore 56 at the bottom. At the bottom, it has a downward screw tip 57. Through a bypass feed line 59 gas from the shut-off valve 24 to the bypass screw 55 and flows through the bypass hole 56 down past the screw tip 57. By means of a bypass outlet 60, the gas flows back, as it were, below the control valve seat 50 to the first gas outlet 27. This ensures that this bypass gas flow, which is adjustable with the bypass screw 55, always flows to the first gas burner 15, regardless of whether whether the control valve 49 is open or closed.
  • the first gas burner 15 can continue to burn with the lowest possible power, so that its performance is greatly reduced during the control process, but does not run out. This has been explained before.
  • the flow rate can be adjusted by the bypass screw 55 by a known principle by turning the screw and adapted to any type of gas.
  • bypass screw 55 instead of the bypass screw 55 shown here, other embodiments are conceivable.
  • a bypass device could also be provided in the control valve body 51 itself, similar to the aforementioned DE 102013218014 is known, and so for bridging a small gas flow, namely just cause the bypass gas flow past the closed control valve seat 50 over. Then the gas valve housing 22 could be made even smaller and more compact.
  • the gas valve device 20 still has a control valve 63 with a large and conical or truncated cone-shaped control valve body 64 in a correspondingly formed control valve seat 65.
  • the two parts are so accurate that can pass through their mating surfaces no gas flow or gas can not flow undesirable.
  • the control valve body 64 is thereby pressed by a control valve spring 66, which rests on the inside of the rotary shaft holder 31, into the gas valve housing 22 or into the control valve seat 65.
  • a gas channel leads from the shut-off valve 24 via the control valve seat 65 into a drilled gas duct 69 in the control valve body 64.
  • This is formed at least partially outside of the control valve body 64 along as a groove and ends in the Fig. 3 with the groove 70 from which the bypass lead 59 to the bypass screw 55 goes off.
  • This groove 70 is designed here, that only with rotational positions of the rotary knob 21 and thus of the control valve body 64, which correspond to an operation of the first gas burner 15 or cause this, the bypass feed line 59 is in register with the groove 70 and is thus supplied with gas.
  • the control valve 63 is closed.
  • a further groove 71 is formed in the control valve body 64, which is in register with the bypass outlet 60. From the results, as can be seen on the left, a bore in the interior of the control valve 49, which, as explained above, opens below the control valve seat 50.
  • the second gas burner 17 can be operated as a grill burner only with a single power stage, which corresponds to the gas flow resulting from the cross sections. It may alternatively, but also be provided that the groove 74 depending on the rotation angle of the rotary knob is slowly and increasingly brought into overlap with the gas channel 75 for an adjustable flow area at this point, so that the power at the second gas burner 17 are also set can. This is easy to realize for the expert.
  • a driver 61 is provided, which engages in an opening 62 above in the control valve body 64.
