<p>1,206,715. Mixing fluids in flow. DENTATUS A.B. 30 Jan., 1968 [14 Feb., 1967], No. 4841/68. Heading B1C. [Also in Division F2] In apparatus for suspending a mist of oil or other liquid in air or other gas, the main gas current enters the tube 5, passes through openings 12 in a valve member 8 which is lifted from its seat, and through the bores 6 and 7. The openings 12 cause a pressure drop whereby a minor portion of the gas current passes through the annular clearance 26 between a hole 16 in the tube 5 and a suction tube 14, up which liquid is drawn from the transparent container 1 and atomized at the outlet of the tube 14. The oil mist so formed passes under the transparent baffle 18 which intercepts large droplets, and through the passages 19, 37 to rejoin the main gas stream in the bore 6. The amount of liquid entrained may be adjusted by the needle valve 25 in the bypass. The pressure drop and consequently the amount of liquid entrained are maintained substantially constant irrespective of the rate of gas flow, by movement of the valve member 8 to uncover more or less of the openings 12. If gas flow be contained, the valve member 8 may be replaced by a fixed orifice (see Fig. 2, not shown). If it be desired in the embodiment of Fig. 3 shown that the rate of liquid supply increase with increasing gas flow, the compression of the valve spring 9 is increased by means of the adjusting knob 30. Conversely if the rate of liquid supply is to decrease with increasing gas flow, the tubular plug 36 is screwed out into the bore 6 until its plane end 35 acts as a valve seat in cooperation with a plane face 39 on the side of the valve member 8, so that the outlet of the passage 37 into the bore 6 is gradually occluded as the valve member 8 lifts. An embodiment incorporating an air filter (101), air pressure regulator (102) and pressure gauge (116) is described with reference to Figs. 4 and 5, not shown.</p> |
