Abstract

A device for controlling the flow rate of a fuel gas/air mixture, and/or the ratio between the fuel gas and air in such a mixture. The device includes a body having an air inlet, a fuel gas inlet, a fuel gas/air mixture outlet, a gas-control passage in the body, with the cross-sectional area of the gas-control passage being variable via a control device for controlling the flow of fuel gas through the device, and an adjustable air-control passage for adjusting the flow of air through the device. The air-control and gas-control passages are configured and disposed in the body in such a way that they cooperate to also form an area within the body where said controlled fuel gas and air flows are combined and mixed.
