Abstract
A device for controlling gas burners which enables precise adjustment of the heating rate of the burner is disclosed. The device includes an energy regulator which adjusts the heating rate by alternate lighting and extinguishing of the burner in a more or less cyclic manner. In operation, a main control knob is set to obtain the operating rate required. This immediately energizes an electro-valve which feeds gas to a pilot. At the same time, a spark generator is energized to light the pilot light. Once the pilot is lit, a safety inverter turns the spark generator off. A second electro-valve is enabled a predetermined time thereafter and, under the control of the energy regulator, feeds gas to the burner. A thermostatically operated switch may also be placed in series between the energy regulator and the second electro-valve to provide additional control of the heating rate of the burner.

Th is a thermostatic element electrovalve EV2 makes it possible to represent visually the operating of the said electro-valve, hence of the gas burner B. i
The user starts up the operation of the device is as follows the burner by setting the energy regulator REl by means of a control knob M, and positions that knob to obtain the required operating rate, the said knob acting on an adjusting cam C regulating the distance of the bi-metallic strip bi of the energy regulator; such a regulator is known per se and the operating thereof gives the man in the art no difficulty; the coil 1 of the electrovalve EVl is then fed through a break contact R1 of the time delay relay RT; the spark generator G being fed through a break contact R2 of the safety invertor ISM provides for the lighting of the pilot V which heats the tank S of the safety invertor lSM, this bringing make contacts T2 and T3 of the said invertor into play; the said tank S is placed so that it is heated by the pilot and not by the burner. The contact T2 enables the feeding of the coil 1 of the electrovalve EVl without using the time delay relay RT, at the same time as the spark generator stops operating due to the stopping of its electricity supply; the time delay relay then comes into action and, by its make contact Tl, enables the feeding of the coil 2 of the electro-valve EV2, the contact T3 of the safety invertor ISM being closed; the burner B receiving gas is lit by the pilot V. After a certain time, the bi-metallic strip bi of the energy regulator will operate, stopping the electricity supply of the coil 2 of the electrovalve EV2; after a certain time, when the bimetallic strip bi has cooled down, it closes the electricity supply circuit of the coil 2 again, opening the electro-valve EV2, then the burner operates again.
If the temperature of the device heated by the burner B axceeds a certain value detected by the thermostatic element Th. the operation of the latter causes the opening of its contact Thl, this stopping the electricity supply of the electro-valve EV2 of the gas burner B, hence the input of gas to the said burner stops, as long as the contact Thl is not closed, that is, as long as the temperature of the device protected by the thermostatic element Th has not returned to a value lower than the operation value of the said element Th; when the temperature has lowered, the contact Th1 closes and the electro-valve is again fed through the energy regulator.
