Gas valve with a thermostatically controlled gas valve and a thernoelectric ignition safety device

The invention relates to a gas valve with a thermostatically controlled gas valve and a thermoelek-

tric ignition safety device, which are arranged in a common housing, which is covered by a cap is completed, v / obei the gas valve thermostat through | a rotatable adjusting knob and the closing element of the ignition safety valve can be moved into the open position by a pushbutton which is displaceable in the axial direction.

Such gas fittings with a thermostatically controlled gas valve and one that can be actuated by at least one pushbutton thermoelectric ignition safety devices are available in different Embodiments known. The actuation of the thermostat assigned to the gas valve takes place by means of a Adjustment knob and the ignition safety valve by means of a

Push button from the front of the cover cap of the gas valve, so that when the gas valve is installed in a gas-heated one Device must be paid attention to this only possible mode of operation. In some cases the installation of the Gas fittings on gas-heated devices and also the actuation of the actuators are facilitated if another Actuation would be possible.

The object of the invention is therefore to create a gas array, which allows different modes of operation with little effort.

This task is carried out on the easier gas valve of the type mentioned at the beginning Kind according to the invention in that the adjusting knob and the push button either from the end face of the cover cap or are movable from a side wall of the cover cap and that, depending on the desired mode of operation, cover caps are optionally interchangeable with appropriately designed actuators. The arrangement can be made in such a way that the adjusting knob with a protrusion required for actuation and the pushbutton with a lateral approach required for actuation protrude through the side wall of the cover cap. But it also exists the possibility of having a disc-shaped adjusting knob with a protrusion through the front side that is required for actuation of the lateral approach of the push button protrudes and at least frictionally with the axis of rotation of the thermostat connected iat.

In this way, the installation position of the gas valve on the gas-heated Device can be selected more independently and, in addition, a simplification of the operation of the gas valve is achieved. It is essential that the housing of the gas arcsatur with all Internals always have the same uniform training and

are merely _u e for the desired operation, a cover is attached with appropriately designed Botätigungsgliederri so that it selectively at the end face or a side wall of the cap mounted.

The subject matter of the invention is explained in an exemplary embodiment with reference to the drawing.

3 shows a partial view of a gas valve according to FIG. 2, but with a different design of the actuators.

The gas fitting is made of a generally designated 10, Λ housing, each of which is composed of a lower part 101, a garment portion 102 and an upper part 103 with the interposition of sealing gaskets. The housing 10 is closed at its upper part 103 by a cover cap 11. Actuating elements for the individual parts built into the housing 10 protrude through the cover cap 11. According to the drawing, viewed from right to left, these built-in parts consist of a gas pressure regulator which is arranged behind a cover plate 104 which is releasably fastened to the smock part 102 of the housing 10 ' . Following this, a known thermoelectric ignition safety device is installed, which acts as an actuator

a push button for moving the closing element of the ignition safety valve into the open position and also assigned to moving the closing member of the main gas valve into the open position is. A thermostatically controlled gas valve, which is also known per se, is arranged thereafter, which axially parallel to the thermoelectric ignition safety device and also axially parallel to that for controlling the gas valve serving thermostat is arranged. A rotatable adjusting knob is assigned to the thermostat as an actuator.

In the embodiment according to Figure 1, the actuation ™ protrude members for the thermoelectric ignition safety device and the thermostat of the gas valve through the end face 111 of the cap 11 and that is the push button 12 for actuating the closing element of the ignition safety valve and around the setting button 13 for setting the thermostat of the gas valve.

In the embodiment according to FIG. 2, the operation takes place Actuating members on the side wall 212 of the cap 21. The actuating members have a corresponding design for this purpose on, namely the push button 22 for actuating the ignition safety valve with a laterally protruding shoulder 221 k provided, which through a corresponding recess on the side wall 212 of the cap 21 .throughout. If the cap 21, as in the illustrated embodiment, only a relatively Has low height, the recess in the upper part 103 of the housing 10 is continued to the required stroke of the Enable push button 22. To operate the thermostat of the gas valve, an adjusting knob 23 is provided in this case, which protrudes through the side wall 212 of the cover cap 21 with a protrusion required for actuation. To this In this way, the two actuators can be operated from the side wall of the cover cap 21. In the embodiment

according to FIG. 3, the operation is the same as with the execution horn according to Figure 2, however in this case both a push button 32 with a side button Approach 321 as well as a disk-shaped adjusting knob '33 too summarized in one structural unit. The push button 32 protrudes like in the embodiment according to Figure 2 by a recess in the side wall 312 of the cap 31 with continuation in Upper part 103 of the housing 10 through and the disk-shaped adjusting knob 33 protrudes with a necessary for its actuation Overhang through the end face 322 of the lateral extension 321 of the push button 32, within 'which the disk-shaped adjusting knob 33 is rotatably mounted. Of the disk-shaped adjusting knob 33 is in this case at least positively connected to the axis of rotation of the thermostat, for example via a cable drive, it can of course also be positively locked via a gear ratio with the axis of rotation of the Thermostats connected.

This different arrangement of the actuators for the ignition safety valve and the thermostat of the gas valve enables the gas valve to be adapted to the installation conditions on the gas-heated device and to the desired operating method. For this purpose, only an optional replacement of a cover cap f (e.g. 11) with actuators for another cover cap ^: (e.g. 21 or 31) with appropriately designed actuators is required, so that the housing 10 with the gas valve with all of its internals is made essentially uniform, but can be used universally by attaching a corresponding cover cap 11 or 21 or 31. There is also the possibility of using the pushbutton 12 or 22 or 32 to shut off the gas supply, namely by moving the pushbutton 'beyond its basic position further outwards in the axial direction, whereby at least the main gas supply and the corresponding
