1,201,203. Spray carburetters; treating charge. ENERGY TRANSFORMATION CORP. Aug.31, 1967 [Aug.31, 1966], No.23482/67. Heading F1B. Baffle devices 27, 30, Fig. 1 produce eddies in the mixture flow which break up heavy fuel particles collecting adjacent the baffles. The fuel-air mixture is diverted outwards by baffle 27, and inwards by annular baffle 30, the light fuel particles flowing with the stream around the baffles whereas the heavy particles are diverted out of the stream against the baffles. In Fig. 4 (not shown) the first baffle (37) is a cone which diverts the flow outwards towards an annular baffle (40) with a concave surface facing upstream. A third baffle comprising a concave disc (42) is provided downstream of baffle (40). In Fig. 10 aerated fuel issues from orifices 72c of a suction-actuated disc 72b attached to a sliding stem 72 which co-operates with a fuel metering pin 78a in a chamber 78 supplied from a float chamber. The disc 72b co-operates with an aperture 70a in a baffle 70, a second baffle 80 being provided downstream of the nozzle. The fuel nozzle is supplied by a tube (76a) Fig. 11 (not shown) the end of which is positioned at the centre of the float chamber (53) to reduce the effects of tilting.
