摘要： A premixing apparatus has a butterfly valve (7) and a changeover valve (8) for changing over, between high and low, a ventilation resistance in an air supply passage (3) and in a gas supply passage (4), respectively; and an interlocking mechanism (9) to open or close the changeover valve in interlocking with the opening or closing of the butterfly valve. In either of the small-capacity state in which the ventilation resistance in the air supply passage and in the gas supply passage is made high to attain a small-capacity state or in a large-capacity state to attain a large-capacity state, adjustments are arranged to be made to make appropriate the excess air ratio of the air-fuel mixture. An interlocking mechanism (9) is constituted: to maintain the changeover valve (8) in a fully-closed state when the butterfly valve (7) lies in a predetermined first rotation angle range inclusive of the closed posture; and to maintain the changeover valve (7) in a fully-opened state when the butterfly valve (7) lies in a predetermined second rotation angle range inclusive of the opened posture. The rotation angle of the butterfly valve (7) at which the excess air ratio of the air-fuel mixture becomes the predetermined appropriate value within the first rotation angle range is set to a closing-side stop angle of the butterfly valve (7). The rotation angle of the butterfly valve (7) at which the excess air ratio of the air-fuel mixture becomes the predetermined appropriate value within the second rotation angle range is set to an opening-side stop angle of the butterfly valve (7).

摘要： Device for protecting the oxygen and gas supply to a cutting torch (4) which is of the type operated by a negative pressure in the gas supply line (2', 2"). The device consists of a housing (8) which comprises an inner chamber which is divided into an upper (9') and a lower (9") chamber by a diaphragm (10). Said diaphragm controls a gas valve (13) which can allow gas to pass to the lower chamber from a supply (1), which lower chamber is connected to the cutting torch via the gas supply (2', 2"). Subsequently, the diaphragm actuates an oxygen valve (14) which can allow oxygen to pass to the cutting torch directly from the oxygen supply (1) via the oxygen supply (3', 3"). All this is arranged in such a manner that when there is no negative pressure in the gas supply line (2', 2"), the diaphragm closes the two valves (13, 14), so that the supply of gas and oxygen to the cutting torch stops.
