REGULATING DEVICE FOR GAS BURNERS
First Claim
1. A regulating device for providing a desired gas/air mixture to a gas burner, wherein a gas line provides a source of gas to a gas valve, and the gas valve provides a regulated gas flow based at least in part on a signal provided by a sensor, wherein the signal provided by the sensor is related to a gas pressure of the regulated gas flow against a reference pressure at a reference pressure input of the sensor, the regulating device comprising:
- a mixing device for mixing the regulated gas flow with a combustion air flow to produce a gas/air mixture to the gas burner, the mixing device includes a venturi nozzle, wherein the regulated gas flow is provide to a mixing region of the venturi nozzle in which the regulated gas flow and the combustion air flow are mixed to form the desired gas/air mixture;
a device having an inner chamber and an outer chamber separated by a filter, wherein the inner chamber is fluidly coupled to the reference pressure input of the sensor, and the outer chamber is fluidly coupled to a region of the mixing device that is downstream of the mixing region of the venturi nozzle via a connecting line; and
a flow guiding element associated with the outer chamber of the device, wherein the flow guiding element helps guide and/or capture an ambient air flow from an ambient atmosphere to the outer chamber, and further helps guide and/or capture a flow from the reference pressure input of the sensor, which has crossed over from the inner chamber and into the outer chamber through the filter.

Abstract
Regulating device for gas burners for providing a gas/air mixture, with a mixing device for mixing a gas flow with a combustion air flow and therefore for providing the gas/air mixture, wherein in a gas line which conducts the gas flow at least one gas valve is positioned, which is adjusted in dependence upon a measurement signal of an electric or electronic sensor, wherein the sensor acts on the gas line by a measuring point and wherein a reference pressure prevails on a reference point of the sensor. The mixing device may be formed as a Venturi nozzle, wherein the gas line leads to a mixing region of the Venturi nozzle in which the gas flow and the combustion air flow are mixed, wherein the reference point of the sensor acts on a device in which the reference pressure prevails, and wherein the device may be connected via a connecting line to the Venturi nozzle, that is to say to a region of the Venturi nozzle which lies downstream of the mixing region of the Venturi nozzle.
