Abstract

1,162,304. Regulating air supply. REDFYRE Ltd. 26 March, 1968 [30 March, 1967], No. 14496/67. Heading F4W. In a natural draught heating appliance, e.g. a solid fuel stove, the supply of combustion air to the appliance is automatically controlled in dependence of the draught at the flue outlet 3 by means of a butterfly valve 6 positioned in the combustion air inlet 4. The butterfly valve comprises a pivoted plate 11 extending through a rectangular opening 10 in an inclined frame 7. A weight 16 is attached to the plate 11 which is held vertically in an open position by gravity. In operation changes in the flue draught, e.g. due to variations in atmospheric conditions, cause the valve to close or open to keep the rate of flow of combustion air to the appliance steady. The upper part of the opening 10 is provided with a masking plate 19. A manually adjustable damper 5 in the form of a sliding gate valve is also provided in the combustion air inlet 4.
