摘要： A pressure reducer includes a housing, defining upstream and downstream pressure chambers. A valve is positioned in the housing and includes a diaphragm acting on a valve tappet. The valve includes a valve body fastened to the valve tappet and cooperating with a sealing element. The valve body has a cylindrical, hollow-cylindrical, or conical contour and forms a sealing surface effective in the radial direction. The sealing surface is interrupted at at least one circumferential position by a flow channel, such that, depending on a pressure drop in the downstream pressure chamber, either the sealing element lies against the sealing surface and completely closes a flow region between the sealing element and the sealing surface or the sealing element is removed from the sealing surface and completely opens the flow region or the sealing element lies against the sealing surface and partly opens the flow region exclusively by the respective flow channel.

摘要： Flow modulator (10) for a fluid like combustion gas, comprising: a housing (11), a modulator body (14) positioned with the housing (11), and a valve body (18) positioned with the housing (11). The modulator body (14) has a flow channel (15) and an opening (16) providing together a flow passage (17) for the fluid. The valve body (18) is provided by a foil element (19), wherein the foil element (19) has an opening (20) for the fluid, wherein the foil element (19) is rotatable relative to the modulator body (14) to modulate the flow of the fluid by adjusting an overlap between the opening (20) of the valve body (18) and the flow passage (17) of the modulator body (14), and wherein the foil element (19) is positioned up-stream of the modulator body (14) such that an inlet pressure of the fluid presses the foil element (19) against the modulator body (14) thereby providing a sealing level between the foil element (19) and the modulator body (14).

摘要： A device for handling combustion gas comprises: a housing, a first electronic element, a second electronic element, a connecting element, and a sealing element. The housing defines a gas chamber for the combustion gas and an ambient chamber for ambient air. The first electronic element is positioned within the gas chamber and is exposed to the combustion gas. The second electronic element is positioned within the ambient chamber and is not exposed to the combustion gas but is exposed to the ambient air. The connecting element electrically connects the first electronic element and the second electronic element. The sealing element is made at least partially from an elastomer, and is compressed between the connecting element and the housing, and seals the gas chamber against the ambient chamber even if electrically insulating material of the connecting element or the connecting element is removed.

The gas burner appliance (10) is operated to compensate for a fluctuating gas inlet pressure of the gas burner appliance by executing the following steps: Measure a first absolute pressure by the absolute pressure sensor (21) when at least the first gas safety valve (19a) of the gas safety valve unit (19) is closed. Measure a second absolute pressure by the absolute pressure sensor (21) when the gas safety valve unit (19) is opened. Determine a pressure difference between the first absolute pressure or a pressure depending on the first absolute pressure and the second absolute pressure or a pressure depending on the second absolute pressure. Operate the gas flow modulator (18) dependent from said pressure difference.

摘要： A method may measure a respective temperature at a respective remote location or at the respective water pipe with the respective temperature sensor. A method may determine from the respective temperature measured by the respective temperature sensor a water usage event at the respective remote location. A method may determine during a determined water usage event a temperature profile from the temperature measured by the respective temperature sensor. A method may determine from the temperature profile determined during the water usage event a risk factor of microbiological growth at the respective remote location or of microbiological growth within the respective water pipe. A method may execute a disinfection cycle for the respective remote location or the respective water pipe if the respective risk factor of microbiological growth is above a respective risk threshold.

摘要： In some examples, a method for operating a gas burner appliance includes determining, on basis of a nominal burner-load and on basis of a mixing ratio of gas and air of a gas/air mixture or a λ-value of the gas/air mixture, a nominal air mass flow in order to provide the nominal burner-load. The method further comprises determining the ambient air pressure and the ambient air temperature of the ambient air, determining, on basis of the ambient air pressure and on basis of the ambient air temperature, the atmospheric density of the ambient air, determining on basis of the nominal air mass flow, on basis of the determined atmospheric density of the ambient air, and on basis of a system resistance of the gas burner appliance, the fan speed of the fan in order to provide the nominal burner-load.
