Abstract
The invention relates to a device for providing a gas/combustion air mixture for a gas burner, comprising a fan (11) for providing a combustion air flow, a gas control device for providing a gas flow and a mixing device (13) for mixing the combustion air flow and the gas flow, thus providing the gas/combustion air mixture. Said mixing device (13) and the fan (11) are connected together on one side, and on the other side, the mixing device and the gas control device are connected together. According to the invention, the mixing device (13) and the fan (11) are connected together in such a manner that a vibration absorber (15) is arranged between a connecting section (12) of the mixing device (13) and a connecting section (10) of the fan (11).
Claims20
A device for providing a gas/combustion air mixture for a gas burner, with a fan for providing a combustion air flow, with a gas regulating device for providing a gas flow, and with a mixing device for mixing the combustion air flow and the gas flow and therefore for providing the gas/combustion air mixture, wherein on one side of the mixing device, the mixing device and the fan are interconnected, and on the other side of the mixing device, the mixing device and the gas regulating device are interconnected, and wherein a vibration absorber is arranged between a connecting section of the mixing device and a connecting section of the fan, wherein the connecting section of the mixing device and the connecting section of the fan extend along a longitudinal axis of the device, and wherein the vibration absorber includes an engagement feature for mechanically engaging with a corresponding engagement feature of the device to form an interference connection, wherein the engagement feature of the vibration absorber is configured to restrict movement of the vibration absorber relative to the corresponding engagement feature of the device along the longitudinal axis in both directions.
An apparatus for providing a gas/combustion air mixture to a gas burner, comprising:
- a gas regulating device for providing a gas flow;
- a fan for providing a combustion air flow, the fan having a connecting section;
- a mixing device for mixing the combustion air flow and the gas flow to produce the gas/combustion air mixture, the mixing device having a connecting section;
- and
- a vibration absorber arranged between the connecting section of the mixing device and the connecting section of the fan, wherein the connecting section of the mixing device and the connecting section of the fan extend along a longitudinal axis of the device, and wherein the vibration absorber includes one or more engagement feature each for mechanically engaging one or more corresponding engagement feature along the connecting sections of the mixing device and/or fan to form an interference connection that mechanically secures the vibration absorber such that movement of the vibration absorber is restricted along the longitudinal axis in both directions.
A device for directing a gas/combustion air mixture to a gas burner, comprising:
- a fan, the fan having a connecting section;
- a mixing device, the mixing device having a connecting section, wherein the connecting section of the fan and the connecting section of the mixing device are concentrically arranged along a longitudinal axis;
- and
- a vibration absorber situated between the concentrically arranged connecting sections of the mixing device and the fan, wherein the vibration absorber is formed from an elastomeric material, and wherein the vibration absorber is held in place by an interlocking connection between an engagement feature of the vibration absorber and a corresponding engagement feature of the device that secures the vibration absorber in place such that movement of the vibration absorber is restricted along the longitudinal axis in both directions.
